In the present work, we developed a new method to efficiently coat CsPbX3 NCs, which resulted in their increased chemical and optical stability as well as processability. The method is based on the incorporation of poly(maleic anhydride-alt-1-octadecene) (PMA) into the synthesis of the perovskite NCs. The presence of PMA in the ligand shell stabilizes the NCs by tightening the ligand binding, limiting in this way the NC surface interaction with the surrounding media. We further show that these NCs can be embedded in self-standing silicone/glass plates as down-conversion filters for the fabrication of monochromatic green and white light emitting diodes (LEDs) with narrow bandwidths and appealing color characteristics.","lang":"eng"}]},{"_id":"367","oa_version":"None","citation":{"apa":"Ibáñez, M., Berestok, T., Dobrozhan, O., Lalonde, A., Izquierdo Roca, V., Shavel, A., … Cabot, A.

In this direction, while impressive advances have been achieved in the past decade in the synthesis of multicomponent nanoparticles and nanocomposites, element rearrangement during catalyst activation has been frequently overseen. Here, we present a facile galvanic replacement-based procedure to synthesize Co@Cu nanoparticles with narrow size and composition distributions. We further characterize their phase arrangement before and after catalytic activation. When oxidized at 350 °C in air to remove organics, Co@Cu core-shell nanostructures oxidize to polycrystalline CuO-Co3O4 nanoparticles with randomly distributed CuO and Co3O4 crystallites. During a posterior reduction treatment in H2 atmosphere, Cu precipitates in a metallic core and Co migrates to the nanoparticle surface to form Cu@Co core-shell nanostructures. The catalytic behavior of such Cu@Co nanoparticles supported on mesoporous silica was further analyzed toward CO2 hydrogenation in real working conditions.","lang":"eng"}],"quality_controlled":"1","article_type":"original","publication_identifier":{"eissn":["1520-5827"],"issn":["0743-7463"]},"year":"2016","extern":"1","author":[{"first_name":"Raquel","full_name":"Nafria, Raquel","last_name":"Nafria"},{"last_name":"Genç","full_name":"Genç, Aziz","first_name":"Aziz"},{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria","orcid":"0000-0001-5013-2843","last_name":"Ibáñez","full_name":"Ibáñez, Maria"},{"last_name":"Arbiol","full_name":"Arbiol, Jprdi","first_name":"Jprdi"},{"last_name":"Ramírez De La Piscina","full_name":"Ramírez De La Piscina, Pilar","first_name":"Pilar"},{"last_name":"Homs","full_name":"Homs, Narcís","first_name":"Narcís"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"}],"date_created":"2018-12-11T11:46:04Z","language":[{"iso":"eng"}],"page":"2267 - 2276","month":"03","issue":"9"},{"abstract":[{"text":"The efficient conversion between thermal and electrical energy by means of durable, silent and scalable solid-state thermoelectric devices has been a long standing goal. While nanocrystalline materials have already led to substantially higher thermoelectric efficiencies, further improvements are expected to arise from precise chemical engineering of nanoscale building blocks and interfaces. Here we present a simple and versatile bottom-up strategy based on the assembly of colloidal nanocrystals to produce consolidated yet nanostructured thermoelectric materials. In the case study on the PbS-Ag system, Ag nanodomains not only contribute to block phonon propagation, but also provide electrons to the PbS host semiconductor and reduce the PbS intergrain energy barriers for charge transport. Thus, PbS-Ag nanocomposites exhibit reduced thermal conductivities and higher charge carrier concentrations and mobilities than PbS nanomaterial. Such improvements of the material transport properties provide thermoelectric figures of merit up to 1.7 at 850 K.","lang":"eng"}],"quality_controlled":"1","article_type":"original","DOAJ_listed":"1","OA_type":"gold","type":"journal_article","scopus_import":"1","publication":"Nature Communications","intvolume":"         7","article_processing_charge":"No","date_published":"2016-03-07T00:00:00Z","volume":7,"doi":"10.1038/ncomms10766","oa":1,"date_updated":"2026-05-13T13:59:30Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/ncomms10766"}],"month":"03","author":[{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria","last_name":"Ibanez Sabate","orcid":"0000-0001-5013-2843","full_name":"Ibanez Sabate, Maria"},{"first_name":"Zhishan","full_name":"Luo, Zhishan","last_name":"Luo"},{"last_name":"Genç","full_name":"Genç, Azoz","first_name":"Azoz"},{"full_name":"Piveteau, Laura","last_name":"Piveteau","first_name":"Laura"},{"full_name":"Ortega, Silvia","last_name":"Ortega","first_name":"Silvia"},{"first_name":"Doris","full_name":"Cadavid, Doris","last_name":"Cadavid"},{"full_name":"Dobrozhan, Oleksandr","last_name":"Dobrozhan","first_name":"Oleksandr"},{"id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu","orcid":"0000-0001-7313-6740","last_name":"Liu","full_name":"Liu, Yu"},{"last_name":"Nachtegaal","full_name":"Nachtegaal, Maarten","first_name":"Maarten"},{"first_name":"Mona","last_name":"Zebarjadi","full_name":"Zebarjadi, Mona"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"first_name":"Maksym","full_name":"Kovalenko, Maksym","last_name":"Kovalenko"},{"first_name":"Andreu","last_name":"Cabot","full_name":"Cabot, Andreu"}],"date_created":"2018-12-11T11:46:04Z","language":[{"iso":"eng"}],"extern":"1","year":"2016","publication_identifier":{"eissn":["2041-1723"]},"publist_id":"7463","day":"07","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","publication_status":"published","license":"https://creativecommons.org/licenses/by/4.0/","external_id":{"pmid":[" 26948987"]},"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"status":"public","publisher":"Nature Publishing Group","article_number":"10766","oa_version":"Published Version","_id":"369","citation":{"ieee":"M.

In such applications, the use of solution-processed nanocrystals (NCs) to produce thin films or bulk nanomaterials has associated several potential advantages, such as high material yield and throughput, and composition control with unmatched spatial resolution and cost. Here we report on the production of Cu3SbSe4 (CASe) NCs with tuned amounts of Sn and Bi dopants. After proper ligand removal, as monitored by nuclear magnetic resonance and infrared spectroscopy, these NCs were used to produce dense CASe bulk nanomaterials for solid state TE energy conversion. By adjusting the amount of extrinsic dopants, dimensionless TE figures of merit (ZT) up to 1.26 at 673 K were reached. Such high ZT values are related to an optimized carrier concentration by Sn doping, a minimized lattice thermal conductivity due to efficient phonon scattering at point defects and grain boundaries, and to an increase of the Seebeck coefficient obtained by a modification of the electronic band structure with Bi doping. Nanomaterials were further employed to fabricate ring-shaped TE generators to be coupled to hot pipes, which provided 20 mV and 1 mW per TE element when exposed to a 160 °C temperature gradient. The simple design and good thermal contact associated with the ring geometry and the potential low cost of the material solution processing may allow the fabrication of TE generators with short payback times."}],"date_updated":"2026-05-13T13:12:04Z","doi":"10.1039/C6TA08467B","volume":5,"date_published":"2016-12-19T00:00:00Z","article_processing_charge":"No","page":"2592 - 2602","date_created":"2018-12-11T11:46:05Z","language":[{"iso":"eng"}],"author":[{"id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu","last_name":"Liu","orcid":"0000-0001-7313-6740","full_name":"Liu, Yu"},{"last_name":"García","full_name":"García, Gregorio","first_name":"Gregorio"},{"last_name":"Ortega","full_name":"Ortega, Silvia","first_name":"Silvia"},{"last_name":"Cadavid","full_name":"Cadavid, Doris","first_name":"Doris"},{"full_name":"Palacios, Pablo","last_name":"Palacios","first_name":"Pablo"},{"full_name":"Lu, Jinyu","last_name":"Lu","first_name":"Jinyu"},{"full_name":"Ibanez, Maria","last_name":"Ibanez","first_name":"Maria"},{"first_name":"Lili","last_name":"Xi","full_name":"Xi, Lili"},{"last_name":"De Roo","full_name":"De Roo, Jonathan","first_name":"Jonathan"},{"last_name":"López","full_name":"López, Antonio","first_name":"Antonio"},{"last_name":"Márti Sánchez","full_name":"Márti Sánchez, Sara","first_name":"Sara"},{"full_name":"Cabezas, Ignasi","last_name":"Cabezas","first_name":"Ignasi"},{"first_name":"Maria","last_name":"De La Mata","full_name":"De La Mata, Maria"},{"full_name":"Luo, Zhishan","last_name":"Luo","first_name":"Zhishan"},{"first_name":"Chaocha","full_name":"Dun, Chaocha","last_name":"Dun"},{"full_name":"Dobrozhan, Oleksandr","last_name":"Dobrozhan","first_name":"Oleksandr"},{"full_name":"Carroll, David","last_name":"Carroll","first_name":"David"},{"first_name":"Wenging","last_name":"Zhang","full_name":"Zhang, Wenging"},{"full_name":"Martins, José","last_name":"Martins","first_name":"José"},{"first_name":"Mksym","last_name":"Kovalenko","full_name":"Kovalenko, Mksym"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"last_name":"Noriega","full_name":"Noriega, German","first_name":"German"},{"first_name":"Jiming","last_name":"Song","full_name":"Song, Jiming"},{"first_name":"Perla","last_name":"Wahnón","full_name":"Wahnón, Perla"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"}],"issue":"6","month":"12","publication_identifier":{"eissn":["2050-7496"],"issn":["2050-7488"]},"year":"2016","extern":"1"},{"month":"11","keyword":["nanoparticle","iron oxide","magnetite","core−shell nanostructure","electrocatalysts","oxygen evolution reaction","OER"],"issue":"43","author":[{"last_name":"Luo","full_name":"Luo, Zhishan","first_name":"Zhishan"},{"last_name":"Márti Sánchez","full_name":"Márti Sánchez, Sara","first_name":"Sara"},{"first_name":"Raquel","full_name":"Nafria, Raquel","last_name":"Nafria"},{"last_name":"Joshua","full_name":"Joshua, Gihan","first_name":"Gihan"},{"full_name":"De La Mata, Maria","last_name":"De La Mata","first_name":"Maria"},{"last_name":"Guardia","full_name":"Guardia, Pablo","first_name":"Pablo"},{"last_name":"Flox","full_name":"Flox, Christina","first_name":"Christina"},{"first_name":"Carlos","full_name":"Martínez Boubeta, Carlos","last_name":"Martínez Boubeta"},{"first_name":"Konstantinos","last_name":"Simeonidis","full_name":"Simeonidis, Konstantinos"},{"first_name":"Jordi","full_name":"Llorca, Jordi","last_name":"Llorca"},{"last_name":"Morante","full_name":"Morante, Joan","first_name":"Joan"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria","last_name":"Ibanez Sabate","orcid":"0000-0001-5013-2843","full_name":"Ibanez Sabate, Maria"},{"last_name":"Cabot","full_name":"Cabot, Andreu","first_name":"Andreu"}],"date_created":"2018-12-11T11:46:05Z","language":[{"iso":"eng"}],"page":"29461 - 29469","extern":"1","year":"2016","publication_identifier":{"issn":["1944-8244"],"eissn":["1944-8252"]},"abstract":[{"lang":"eng","text":"The design and engineering of earth-abundant catalysts that are both cost-effective and highly active for water splitting are crucial challenges in a number of energy conversion and storage technologies.

Specifically, the Ag-Au-Se system has been explored from a synthetic point of view, which leads to a set of Ag2Se-based hybrid and ternary nanoparticles including the room temperature synthesis of the rare ternary Ag3AuSe2 fischesserite phase. An in-depth structural and chemical characterization of all nanomaterials has been performed, which proofed especially useful for unravelling the reaction mechanism behind the formation of the ternary phase in solution. The work is complemented with the thermal and electric characterization of a ternary Ag-Au-Se nanocomposite with promising results: we found that the use of the ternary nanocomposite represents a clear improvement in terms of thermoelectric energy conversion as compared to a binary Ag-Se nanocomposite analogue.

Lead chalcogenide QDs are known to crystallize in the rock-salt structure, although with very different atomic order and stoichiometry in the core and surface regions; however, there exists no convincing prior identification of how extreme downsizing and surface-induced ligand effects influence structural distortion. Using forefront X-ray scattering techniques and density functional theory calculations, here we have identified that, at sizes below 8 nm, PbS and PbSe QDs undergo a lattice distortion with displacement of the Pb sublattice, driven by ligand-induced tensile strain. The resulting permanent electric dipoles may have implications on the oriented attachment of these QDs. Evidence is found for a Pb-deficient core and, in the as-synthesized QDs, for a rhombic dodecahedral shape with nonpolar {110} facets. On varying the nature of the surface ligands, differences in lattice strains are found."}],"quality_controlled":"1","publication":"Nature Materials","intvolume":"        15","scopus_import":"1","OA_type":"closed access","type":"journal_article"},{"publisher":"Royal Society of Chemistry","status":"public","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 3.0 Unported (CC BY 3.0)","legal_code_url":"https://creativecommons.org/licenses/by/3.0/legalcode","short":"CC BY (3.0)"},"license":"https://creativecommons.org/licenses/by/3.0/","publication_status":"published","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","day":"13","publist_id":"7448","OA_place":"publisher","title":"Colloidal AgSbSe2 nanocrystals: surface analysis, electronic doping and processing into thermoelectric nanomaterials","citation":{"apa":"Liu, Y., Cadavid, D., Ibáñez, M., De Roo, J., Ortega, S., Dobrozhan, O., … Cabot, A.

Here, we present our experimental results on the thermal and electrical transport properties of PbS-metal composites produced by a versatile particle blending procedure, and where the metal work function allows injecting electrons to the intrinsic PbS host. We compare the thermoelectric performance of composites with microcrystalline or nanocrystalline structures. The electrical conductivity of the microcrystalline host can be increased several orders of magnitude with the metal inclusion, while relatively high Seebeck coefficient can be simultaneously conserved. On the other hand, in nanostructured materials, the host crystallites are not able to sustain a band bending at its interface with the metal, becoming flooded with electrons. This translates into even higher electrical conductivities than the microcrystalline material, but at the expense of lower Seebeck coefficient values.","lang":"eng"}]},{"publist_id":"7440","acknowledgement":"The authors would like to thank C.

The strong time-periodic potential of intense laser light can be used to generate hybrid photon-electron states. Interaction of light with Bloch states leads to Floquet-Bloch states, which are essential in realizing new photo-induced quantum phases. Similarly, dressing of free-electron states near the surface of a solid generates Volkov states, which are used to study nonlinear optics in atoms and semiconductors. The interaction of these two dynamic states with each other remains an open experimental problem. Here we use time- and angle-resolved photoemission spectroscopy (Tr-ARPES) to selectively study the transition between these two states on the surface of the topological insulator Bi2Se3. We find that the coupling between the two strongly depends on the electron momentum, providing a route to enhance or inhibit it. Moreover, by controlling the light polarization we can negate Volkov states to generate pure Floquet-Bloch states.

We suggest that the growth of SMBHs above a few 10^{10} M_sun is prevented by small-scale accretion physics, independent of the properties of their host galaxies or of cosmology. Growing more massive BHs requires a gas supply rate from galactic scales onto a nuclear region as high as >10^3 M_sun/yr. At such a high accretion rate, most of the gas converts to stars at large radii (~10-100 pc), well before reaching the BH. We adopt a simple model (Thompson et al. 2005) for a star-forming accretion disk, and find that the accretion rate in the sub-pc nuclear region is reduced to the smaller value of at most a few M_sun/yr. This prevents SMBHs from growing above ~10^{11} M_sun in the age of the Universe. Furthermore, once a SMBH reaches a sufficiently high mass, this rate falls below the critical value at which the accretion flow becomes advection dominated. Once this transition occurs, BH feeding can be suppressed by strong outflows and jets from hot gas near the BH. We find that the maximum SMBH mass, given by this transition, is between M_{BH,max} ~ (1-6) * 10^{10} M_sun, depending primarily on the efficiency of angular momentum transfer inside the galactic disk, and not on other properties of the host galaxy.","lang":"eng"}],"intvolume":"       828","publication":"The Astrophysical Journal","type":"journal_article","arxiv":1,"scopus_import":"1","date_published":"2016-09-12T00:00:00Z","article_processing_charge":"No","date_updated":"2024-09-24T08:11:51Z","oa":1,"volume":828,"doi":"10.3847/0004-637x/828/2/110","_id":"17618","oa_version":"Preprint","citation":{"apa":"Inayoshi, K., &#38; Haiman, Z.

For each QSO, we complete a Monte Carlo Markov Chain fitting of the continuum and emission-line properties and perform a visual quality assessment to construct a large data base of robustly fit spectra. With this data set, we construct a covariance matrix to describe the correlations between the high-ionization emission lines Lyα, C iv, Si iv +O iv] and C iii], and find it to be well approximated by an N-dimensional Gaussian distribution. This covariance matrix characterizes the correlations between the linewidth, peak height and velocity offset from systemic while also allowing for the existence of broad- and narrow-line components for Lyα and C iv. We illustrate how this covariance matrix allows us to statistically characterize the intrinsic Lyα line solely from the observed spectrum redward of 1275 Å. This procedure can be used to reconstruct the intrinsic Lyα line emission profile in cases where Lyα may otherwise be obscured.

When analyzing galaxy surveys, redshift information has proven to be a valuable addition to angular shear correlations. We forecast parameter constraints on the triplet (Ω𝑚,𝑤,𝜎8) for a LSST-like photometric galaxy survey, using tomography of the shear-shear power spectrum, convergence peak counts and higher convergence moments. We find that redshift tomography with the power spectrum reduces the area of the 1⁢𝜎 confidence interval in (Ω𝑚,𝑤) space by a factor of 8 with respect to the case of the single highest redshift bin. We also find that adding non-Gaussian information from the peak counts and higher-order moments of the convergence field and its spatial derivatives further reduces the constrained area in (Ω𝑚,𝑤) by factors of 3 and 4, respectively. When we add cosmic microwave background parameter priors from Planck to our analysis, tomography improves power spectrum constraints by a factor of 3. Adding moments yields an improvement by an additional factor of 2, and adding both moments and peaks improves by almost a factor of 3 over power spectrum tomography alone. We evaluate the effect of uncorrected systematic photometric redshift errors on the parameter constraints. We find that different statistics lead to different bias directions in parameter space, suggesting the possibility of eliminating this bias via self-calibration.","lang":"eng"}],"quality_controlled":"1","publication":"Physical Review D","intvolume":"        94","type":"journal_article","arxiv":1,"scopus_import":"1","article_processing_charge":"No","date_published":"2016-09-30T00:00:00Z","oa":1,"date_updated":"2024-09-24T08:54:34Z","doi":"10.1103/physrevd.94.063534","volume":94,"issue":"6","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.1605.01100"}],"month":"09","author":[{"last_name":"Petri","full_name":"Petri, Andrea","first_name":"Andrea"},{"last_name":"May","full_name":"May, Morgan","first_name":"Morgan"},{"full_name":"Haiman, Zoltán","last_name":"Haiman","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"}],"date_created":"2024-09-05T13:55:24Z","language":[{"iso":"eng"}],"extern":"1","year":"2016","publication_identifier":{"issn":["2470-0010","2470-0029"]},"day":"30","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publication_status":"published","external_id":{"arxiv":["1605.01100"]},"article_number":"063534","publisher":"American Physical Society","status":"public","oa_version":"Preprint","_id":"17626","citation":{"mla":"Petri, Andrea, et al. “Cosmology with Photometric Weak Lensing Surveys: Constraints with Redshift Tomography of Convergence Peaks and Moments.” <i>Physical Review D</i>, vol. 94, no. 6, 063534, American Physical Society, 2016, doi:<a href=\"https://doi.org/10.1103/physrevd.94.063534\">10.1103/physrevd.94.063534</a>.","short":"A.

An accurate estimate of the 𝑁𝑏×𝑁𝑏 feature covariance matrix 𝐂 is essential to obtain accurate parameter confidence intervals. When 𝐂 is measured from a set of simulations, an important question is how large this set should be. To answer this question, we construct different ensembles of 𝑁𝑟 realizations of the shear field, using a common randomization procedure that recycles the outputs from a smaller number 𝑁𝑠≤𝑁𝑟 of independent ray-tracing 𝑁-body simulations. We study parameter confidence intervals as a function of (𝑁𝑠, 𝑁𝑟) in the range 1≤𝑁𝑠≤200 and 1≤𝑁𝑟≲105. Previous work [S. Dodelson and M. D. Schneider, Phys. Rev. D 88, 063537 (2013)] has shown that Gaussian noise in the feature vectors (from which the covariance is estimated) lead, at quadratic order, to an 𝑂⁢(1/𝑁𝑟) degradation of the parameter confidence intervals. Using a variety of lensing features measured in our simulations, including shear-shear power spectra and peak counts, we show that cubic and quartic covariance fluctuations lead to additional 𝑂⁢(1/𝑁2𝑟) error degradation that is not negligible when 𝑁𝑟 is only a factor of few larger than 𝑁𝑏. We study the large 𝑁𝑟 limit, and find that a single, 240  Mpc/ℎ sized 5123-particle 𝑁-body simulation (𝑁𝑠=1) can be repeatedly recycled to produce as many as 𝑁𝑟=few×104 shear maps whose power spectra and high-significance peak counts can be treated as statistically independent. As a result, a small number of simulations (𝑁𝑠=1 or 2) is sufficient to forecast parameter confidence intervals at percent accuracy."}],"publication_identifier":{"issn":["2470-0010","2470-0029"]},"extern":"1","year":"2016","language":[{"iso":"eng"}],"date_created":"2024-09-05T13:57:57Z","author":[{"full_name":"Petri, Andrea","last_name":"Petri","first_name":"Andrea"},{"full_name":"Haiman, Zoltán","last_name":"Haiman","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"first_name":"Morgan","last_name":"May","full_name":"May, Morgan"}],"issue":"6","month":"03","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.1601.06792","open_access":"1"}],"article_number":"063524","publisher":"American Physical Society","status":"public","external_id":{"arxiv":["1601.06792"]},"publication_status":"published","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","day":"24","title":"Sample variance in weak lensing: How many simulations are required?","citation":{"ista":"Petri A, Haiman Z, May M. 2016.

Previous theoretical and observational studies have shown that the cosmological constraints on Ωm and σ8 are improved by a factor of up to ~ 2 when peak counts and second-order statistics are combined, compared to using the latter alone. We study the origin of lensing peaks using observational data from the 154 deg2 Canada-France-Hawaii Telescope Lensing Survey. We found that while high peaks (with height κ >3.5 σκ, where σκ is the r.m.s. of the convergence κ) are typically due to one single massive halo of ~1015M⊙, low peaks (κ <~ σκ) are associated with constellations of 2-8 smaller halos (<~1013M⊙). In addition, halos responsible for forming low peaks are found to be significantly offset from the line-of-sight towards the peak center (impact parameter >~ their virial radii), compared with ~0.25 virial radii for halos linked with high peaks, hinting that low peaks are more immune to baryonic processes whose impact is confined to the inner regions of the dark matter halos. Our findings are in good agreement with results from the simulation work by Yang el al. (2011).","lang":"eng"}],"quality_controlled":"1","article_type":"original","arxiv":1,"type":"journal_article","scopus_import":"1","publication":"Physical Review D","intvolume":"        94","article_processing_charge":"No","date_published":"2016-08-26T00:00:00Z","volume":94,"doi":"10.1103/physrevd.94.043533","oa":1,"date_updated":"2024-09-24T12:59:05Z"}]
