The main dogma is the existence of density-dependence mechanisms, which can be modelled with distinct functional forms that depend on the size of the Population. One important class of regulatory functions is the theta-logistic, which generalizes the logistic equation. Using this model as a motivation, this paper introduces a simple dynamical reformulation that generalizes many growth functions. The reformulation consists of two equations, one for population size, and one for the growth rate. Furthermore, the model shows that although population is density-dependent, the dynamics of the growth rate does not depend either on population size, nor on the carrying capacity. Actually, the growth equation is uncoupled from the population size equation, and the model has only two parameters, a Malthusian parameter rho and a competition coefficient theta. Distinct sign combinations of these parameters reproduce not only the family of theta-logistics, but also the van Bertalanffy, Gompertz and Potential Growth equations, among other possibilities. It is also shown that, except for two critical points, there is a general size-scaling relation that includes those appearing in the most important allometric theories, including the recently proposed Metabolic Theory of Ecology. With this model, several issues of general interest are discussed such as the growth of animal population, extinctions, cell growth and allometry, and the effect of environment over a population.

We investigate the model system SiGe/Si(0 0 1) by a new approach based on &quot;reading the footprints&quot; which islands leave on the substrate during their growth and evolution. Such footprints consist of trenches carved in the Si substrate. We distinguish between surface footprints and footprints buried below the islands. The former allow us to discriminate islands which are in the process of growing from those which are shrinking. Islands with steep morphologies grow at the expense of smaller and shallower islands, consistent with the kinetics of anomalous coarsening. While shrinking, islands change their shape according to thermodynamic predictions. Buried footprints are investigated by removing the SiGe epilayer by means of selective wet chemical etching. Their reading shows that: (i) during post-growth annealing islands move laterally because of surface-mediated Si-Ge intermixing; (ii) a tree-ring structure of trenches is created by dislocated islands during their &quot;cyclic&quot; growth. This allows us to distinguish coherent from dislocated islands and to establish whether the latter are the result of island coalescence."}],"publisher":"Elsevier","year":"2006","issue":"12","publication":"Microelectronics Journal","author":[{"full_name":"Rastelli, Armando","last_name":"Rastelli","first_name":"Armando"},{"full_name":"Stoffel, Mathieu","last_name":"Stoffel","first_name":"Mathieu"},{"first_name":"Georgios","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","last_name":"Katsaros","full_name":"Georgios Katsaros"},{"last_name":"Tersoff","full_name":"Tersoff, Jerry","first_name":"Jerry"},{"first_name":"Ulrich","last_name":"Denker","full_name":"Denker, Ulrich"},{"last_name":"Merdzhanova","full_name":"Merdzhanova, Tsvetelina","first_name":"Tsvetelina"},{"first_name":"Gouranga","full_name":"Kar, Gouranga S","last_name":"Kar"},{"full_name":"Costantini, Giovanni","last_name":"Costantini","first_name":"Giovanni"},{"first_name":"Klaus","full_name":"Kern, Klaus","last_name":"Kern"},{"first_name":"Hans","last_name":"Von Känel","full_name":"Von Känel, Hans"},{"first_name":"Oliver","last_name":"Schmidt","full_name":"Schmidt, Oliver G"}],"citation":{"apa":"Rastelli, A., Stoffel, M., Katsaros, G., Tersoff, J., Denker, U., Merdzhanova, T., … Schmidt, O.

Because the earliest ionizing sources formed at the locations of the rare density peaks, their spatial distribution was strongly clustered. Here we demonstrate that this clustering significantly boosts the impact of feedback processes operating at high redshift. We build a semianalytical model to include feedback and clustering simultaneously and apply this model to the suppression of star formation in minihalos due to photoionization. The model is built on the excursion-set-based formalism of Furlanetto, Zaldarriaga, and Hernquist, which incorporates the clustering of ionizing sources and which we here extend to include the suppression of star formation in minihalos. We find that clustering increases the mean H II bubble size by a factor of several, and it dramatically increases the fraction of minihalos that are suppressed by a factor of up to ~60 relative to a randomly distributed population. This enhanced suppression can significantly reduce the electron-scattering optical depth τ, as required by the 3 year data from the Wilkinson Microwave Anisotropy Probe. We argue that source clustering is likely to similarly boost the importance of a variety of other feedback mechanisms.","lang":"eng"}],"month":"10","type":"journal_article","status":"public","date_published":"2006-10-01T00:00:00Z","publication_status":"published","scopus_import":"1","date_updated":"2024-09-25T13:27:16Z","oa":1,"title":"Feedback from clustered sources during reionization","main_file_link":[{"url":"https://doi.org/10.1086/506906","open_access":"1"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","page":"570-578","_id":"17718","volume":649,"citation":{"apa":"Kramer, R.

Using these models, we interpret a number of recent observations of extended Lyα blobs (LABs) at high redshift. We suggest, based on the angular size, energetics, relatively shallow surface brightness profiles, and double-peaked spectra, that several of these LABs may be associated with collapsing protogalaxies. We suggest two follow-up observations to diagnose the presence of gas infall. High-S/N spectra of LABs should reveal a preferential flattening of the surface brightness profile at the red side of the line. Complementary imaging of the blobs at redshifted Hα wavelengths should reveal the intrinsic Lyα emissivity and allow its separation from radiative transfer effects. We show that Lyα scattering by infalling gas can reproduce the observed spectrum of the Steidel et al. LAB2 as accurately as a recently proposed outflow model. Finally, we find similar evidence for infall in the spectra of pointlike Lyα emitters. The presence of scattering by the infalling gas implies that the intrinsic Lyα luminosities and derived quantities, such as the star formation rate, in these objects may have been underestimated by about an order of magnitude."}],"publisher":"American Astronomical Society","article_processing_charge":"No","year":"2006","publication":"The Astrophysical Journal","citation":{"short":"M.

These clouds have masses in the range 10^5 -10^7 M_sun, form at high redshifts (z>18), are assumed to lie within the short-lived cosmological HII regions around the first generation of stars. In addition, we study the combined effects of this transient UV flux and a persistent Lyman-Werner (LW) background from distant sources. In the absence of a LW background, we find that a critical specific intensity of J_UV ~ 0.1 x 10^-21 ergs s^-1 cm^-2 Hz^-1 sr^-1 demarcates a transition from net negative to positive feedback for the halo population. A weaker UV flux stimulates subsequent star formation inside the fossil HII regions, by enhancing the H_2 molecule abundance. A stronger UV flux significantly delays star-formation by reducing the gas density, and increasing the cooling time, at the centers of collapsing halos. At a fixed J_UV, the sign of the feedback also depends strongly on the density of the gas at the time of UV illumination. Regardless of the whether the feedback is positive or negative, we find that once the UV flux is turned off, its impact stars to diminish after ~30% of the Hubble time. In the more realistic case when a LW background is present, with J_LW > 0.01 x 10^-21 ergs s^-1 cm^-2 Hz^-1 sr^-1, strong suppression persists down to the lowest redshift (z=18) in our simulations. Finally, we find evidence that heating and photoevaporation by the transient UV flux renders the ~10^6 M_sun halos inside fossil HII regions more vulnerable to subsequent H_2 photo-dissociation by a LW background.","lang":"eng"}],"publisher":"American Astronomical Society","article_processing_charge":"No","year":"2006","publication_status":"published","status":"public","date_published":"2006-09-10T00:00:00Z","type":"journal_article","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","main_file_link":[{"url":"https://doi.org/10.1086/506173","open_access":"1"}],"title":"Ultraviolet radiative feedback on high‐redshift protogalaxies","oa":1,"date_updated":"2024-09-26T07:47:36Z","scopus_import":"1","publication":"The Astrophysical Journal","citation":{"mla":"Mesinger, Andrei, et al. “Ultraviolet Radiative Feedback on High‐redshift Protogalaxies.” <i>The Astrophysical Journal</i>, vol. 648, no. 2, American Astronomical Society, 2006, pp. 835–51, doi:<a href=\"https://doi.org/10.1086/506173\">10.1086/506173</a>.","ieee":"A.

Several theoretical studies have suggested that gas contraction and star-formation in these minihalos was suppressed by radiative, chemical, thermal, and dynamical feedback processes. The recent measurement by the Wilkinson Microwave Anisotropy Probe (WMAP) of the optical depth to electron scattering, tau=0.09+/-0.03, provides the first empirical evidence for this suppression. The new WMAP result is consistent with vanilla models of reionization, in which ionizing sources populate cold dark matter (CDM) halos down to a virial temperature of T_vir=10^4K. On the other hand, we show that in order to avoid overproducing the optical depth, the efficiency for the production of ionizing photons in minihalos must have been about an order of magnitude lower than expected and lower than the efficiency in large halos that can cool via atomic hydrogen (T_vir > 10^4K). This conclusion is insensitive to assumptions about the efficiency of ionizing photon production in the large halos, as long as reionization ends by z=6, as required by the spectra of bright quasars at z<6. Our conclusion is strengthened if the clumping of the ionized gas evolves with redshift, as suggested by semi-analytical predictions and three-dimensional numerical simulations."}],"publisher":"American Astronomical Society","article_processing_charge":"No","year":"2006","article_type":"original","author":[{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","full_name":"Haiman, Zoltán","last_name":"Haiman"},{"last_name":"Bryan","full_name":"Bryan, Greg L.","first_name":"Greg L."}],"fulldoi":"https://doi.org/10.1086/506580","day":"10","extern":"1","publication_identifier":{"issn":["0004-637X","1538-4357"]},"oa_version":"Published Version"},{"type":"journal_article","publication_status":"published","status":"public","date_published":"2006-09-20T00:00:00Z","abstract":[{"lang":"eng","text":"We present Monte Carlo calculations of Lyman alpha (Lya) radiative transfer through collapsing gas clouds, representing proto-galaxies that are caught in the process of their assembly. Such galaxies produce Lya flux over an extended solid angle from a spatially extended Lya emissivity and/or from scattering effects. We study the effect of the gas distribution and kinematics, and of the Lya emissivity profile, on the emergent spectrum and surface brightness distribution. The emergent Lya spectrum is typically double-peaked and asymmetric. In practice, the blue peak is significantly enhanced and the red peak, in most cases, will be undetectable. The resulting effective blueshift, combined with scattering in the intergalactic medium, will render extended Lya emission from collapsing protogalaxies difficult to detect beyond redshift z=4. The surface brightness distribution is typically flat, and a strong wavelength dependence of its slope (with preferential flattening at the red side of the line) would be a robust indication that Lya photons are being generated (rather than just scattered) in a spatially extended region around the galaxy. We also find that for self-ionized clouds whose effective Lya optical depth is less than 10^3, infall and outflow models can produce nearly identical spectra and surface brightness distributions, and are difficult to distinguish from one another. The presence of deuterium with a cosmic abundance may produce a narrow but detectable dip in the spectra of systems with moderate hydrogen column densities, in the range 10^18-10^20 cm^-2.

Furthermore, through ``self-calibration,'' parameters describing the mass-observable relation and cosmology could be simultaneously determined, although at a loss in accuracy by about an order of magnitude. Here we examine an alternative approach to self-calibration, in which a parameterized ab initio physical model is used to compute theoretical mass-observable relations from the cluster structure. As an example, we use a modified-entropy (``preheating'') model of the intracluster medium, with the history and magnitude of entropy injection as unknown input parameters. Using a Fisher matrix approach, we evaluate the expected simultaneous statistical errors on cosmological and cluster model parameters. We find that compared to a phenomenological parameterization of the mass-observable relation, our physical model yields significantly tighter constraints in both surveys and offers substantially improved synergy when the two surveys are combined. In a mock X-ray survey, we find statistical errors on the dark energy equation of state are a factor of 2 tighter than the phenomenological model, with Δw0 ~ 0.08 and its evolution, Δwa ≡ -Δdw/da ~ 0.23, with corresponding errors of Δw0 ~ 0.06 and Δwa ~ 0.17 from a mock Sunyaev-Zel'dovich (SZ) survey, both with Ncl ~ 2.2 × 104 clusters, while simultaneously constraining cluster model parameters to ≲10%. When the two surveys are combined, the constraints tighten to Δw0 ~ 0.03 and Δwa ~ 0.1, a 40% improvement over adding the individual experiment errors in quadrature and a factor of 2 improvement over the phenomenological model.

We calculate the size and orientation of the three-dimensional error ellipse in solid angle and redshift within which the LISA event could be localized using the GW signatures alone. We take into account uncertainties in LISA's measurements of the luminosity distance and direction to the source, in the background cosmology, in weak gravitational lensing magnification due to inhomogeneities along the line of sight, and potential source peculiar velocities. We find that weak lensing errors exceed other sources of uncertainties by nearly an order of magnitude. Under the plausible assumption that BH mergers are accompanied by gas accretion leading to Eddington-limited quasar activity, we then compute the number of quasars that would be found in a typical LISA error volume, as a function of BH mass and redshift. We find that low redshifts offer the best opportunities to identify quasar counterparts to cosmological standard sirens, and that the LISA error volume will typically contain a single near-Eddington quasar at z=1. This will allow a straightforward test of the hypothesis that BH mergers are accompanied by bright quasar activity and, if the hypothesis proves correct, will guarantee the identification of a unique quasar counterpart.

We assume that the star formation rate (SFR) at high redshift traces the formation rate of dark matter halos. We obtain a rate of 0.4-2.3 SNe arcmin^-2 yr^-1 at z ≳ 5 at the near-infrared (4.5 μm) flux density threshold of 3 nJy (achievable with the James Webb Space Telescope [JWST] in a 10^5 s integration). In a hypothetical 1 yr survey, it should be possible to detect up to several thousand SNe per unit redshift at z ~ 6. We discuss the possible application of such a large sample of distant SNe as a probe of the epoch of reionization. By heating the intergalactic medium (IGM) and raising the cosmological Jeans mass, the process of reionization can suppress star formation in low-mass galaxies. This could have produced a relatively sharp drop in the SN rate around the redshift of reionization (zre). We quantify the detectability of this feature in future surveys of distant SNe by varying the redshift and duration of reionization, as well as its impact on the SFR in low-mass halos, which results in different redshifts, widths, and sizes of the drop in the expected SFR. We find that the drop can be detected out to zre ~ 13, as long as (1) the reionization history contains a relatively rapid feature that is synchronized over different regions to within Δz ≲ 1-3, (2) the star formation efficiency in halos that dominate reionization is epsilon* ~ 10%, and (3) reionization significantly suppresses the star formation in low-mass halos. Depending on the details of (1)-(3), this could be achieved with a survey lasting less than 2 weeks. Detecting this signature would also help elucidate the feedback mechanism that regulates reionization."}],"publisher":"American Astronomical Society","year":"2006","article_processing_charge":"No","publication_status":"published","status":"public","date_published":"2006-01-20T00:00:00Z","type":"journal_article","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","main_file_link":[{"url":"https://doi.org/10.1086/498294","open_access":"1"}],"title":"The redshift distribution of distant supernovae and its use in probing reionization","oa":1,"date_updated":"2024-09-30T11:23:16Z","scopus_import":"1","publication":"The Astrophysical Journal","citation":{"short":"A.
