We show that a sufficiently bright quasar (for example, 1/10 as luminous as that recently discovered by Fan et al.) can ionize a large volume, allowing the transmission of a substantial fraction of the flux of its intrinsic Lyα emission line on both sides of the Lyα wavelength. The observed line profile is richly informative. We show that a sufficiently accurate, high spectral resolution (R ≈ 104) measurement of the line profile of a bright quasar is feasible using the Next Generation Space Telescope as well as large ground-based telescopes. Such a measurement has two potentially important applications. First, the red side of the Lyα emission line provides a way to measure the quasar lifetime. Second, the blue side provides a direct measure of the density fluctuations of the IGM at the quasar redshift. The estimate of the absorption of the red side is limited by the accuracy to which the intrinsic profile of the Lyα emission line is known. The blue side, however, does not sensitively depend on the intrinsic profile because the former is much narrower than the latter.","lang":"eng"}],"_id":"17813","publisher":"American Astronomical Society","date_updated":"2024-11-12T10:32:23Z","external_id":{"arxiv":["astro-ph/0006376"]},"title":"Quasar Strömgren spheres before cosmological reionization","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.astro-ph/0006376","open_access":"1"}],"oa_version":"Preprint","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"10","scopus_import":"1","arxiv":1,"publication_status":"published","fulldoi":"https://doi.org/10.1086/312937","publication":"The Astrophysical Journal","intvolume":"       542","extern":"1","status":"public","year":"2000","issue":"2","type":"journal_article","date_created":"2024-09-06T11:42:33Z","oa":1,"date_published":"2000-10-20T00:00:00Z","OA_place":"repository","page":"L75-L78","author":[{"last_name":"Cen","first_name":"Renyue","full_name":"Cen, Renyue"},{"last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","orcid":"0000-0003-3633-5403","first_name":"Zoltán","full_name":"Haiman, Zoltán"}],"day":"20","OA_type":"green","article_type":"original","quality_controlled":"1","volume":542},{"author":[{"full_name":"Haiman, Zoltán","first_name":"Zoltán","last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","orcid":"0000-0003-3633-5403"},{"full_name":"Abel, Tom","first_name":"Tom","last_name":"Abel"},{"first_name":"Martin J.","full_name":"Rees, Martin J.","last_name":"Rees"}],"day":"01","OA_place":"repository","page":"11-24","volume":534,"article_type":"original","OA_type":"green","quality_controlled":"1","publication_status":"published","arxiv":1,"fulldoi":"https://doi.org/10.1086/308723","publication":"The Astrophysical Journal","date_created":"2024-09-06T11:43:22Z","oa":1,"date_published":"2000-05-01T00:00:00Z","intvolume":"       534","extern":"1","status":"public","year":"2000","issue":"1","type":"journal_article","language":[{"iso":"eng"}],"month":"05","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.astro-ph/9903336"}],"oa_version":"Preprint","article_processing_charge":"No","doi":"10.1086/308723","citation":{"mla":"Haiman, Zoltán, et al. “The Radiative Feedback of the First Cosmological Objects.” <i>The Astrophysical Journal</i>, vol. 534, no. 1, American Astronomical Society, 2000, pp. 11–24, doi:<a href=\"https://doi.org/10.1086/308723\">10.1086/308723</a>.","apa":"Haiman, Z., Abel, T., &#38; Rees, M.

The UVB at energies below 13.6 eV suppresses the formation of stars or black holes inside small halos by photodissociating their only cooling agent, molecular H2. We self-consistently compute the buildup of the early UVB in Press-Schechter models, coupled with H2 photodissociation both in the intergalactic medium (IGM) and inside virialized halos. We find that the intergalactic H2 has a negligible effect on the UVB, both because its initial optical depth is small (≲0.1) and because it is photodissociated at an early stage. If the UV sources in the first collapsed halos are stars, then their UV flux suppresses further star formation inside small halos. This results in a pause in the buildup of the UVB, and reionization is delayed until larger halos (Tvir ≳ 10^4 K) collapse. If the small halos host miniquasars with hard spectra extending to ~1 keV, then their X-rays balance the effects of the UVB, the negative feedback does not occur, and reionization could be caused by the small halos."}],"publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"title":"The radiative feedback of the first cosmological objects","_id":"17814","publisher":"American Astronomical Society","date_updated":"2024-11-12T12:17:03Z","external_id":{"arxiv":["astro-ph/9903336"]}},{"publication":"The Astrophysical Journal","publication_status":"published","arxiv":1,"fulldoi":"https://doi.org/10.1086/308557","oa":1,"date_published":"2000-03-20T00:00:00Z","date_created":"2024-09-06T11:45:26Z","issue":"1","type":"journal_article","intvolume":"       532","status":"public","year":"2000","extern":"1","day":"20","author":[{"last_name":"Aguirre","first_name":"Anthony","full_name":"Aguirre, Anthony"},{"first_name":"Zoltán","full_name":"Haiman, Zoltán","orcid":"0000-0003-3633-5403","last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"}],"page":"28-36","OA_place":"repository","volume":532,"quality_controlled":"1","OA_type":"green","article_type":"original","citation":{"ista":"Aguirre A, Haiman Z. 2000.

An alternative explanation of the SN results is an open universe with ΩΛ = 0 and the presence of ≳0.1 μm dust grains with a mass density of Ωdust ~ a few × 10-5 in the intergalactic (IG) medium. The same dust that dims the SNe absorbs the cosmic UV/optical background radiation around ~1 μm, and reemits it at far-infrared (FIR) wavelengths. Here we compare the FIR emission from IG dust with observations of the cosmic microwave (CMB) and cosmic far-infrared backgrounds (FIRB) by the DIRBE/FIRAS instruments. We find that the emission would not lead to measurable distortion of the CMB, but would represent a substantial fraction (≳75%) of the measured value of the FIRB in the 300-1000 μm range. This contribution would be marginally consistent with the present unresolved fraction of the observed FIRB in an open universe. However, we find that IG dust probably could not reconcile the standard Ω = 1 CDM model with the SN observations, even if the necessary quantity of dust existed. Future observations, capable of reliably resolving the FIRB to a flux limit of ~0.5 mJy, along with a more precise measure of the coarse-grained FIRB, will provide a definitive test of the IG dust hypothesis in all cosmologies.","lang":"eng"}],"publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"article_processing_charge":"No","title":"Cosmological constant or intergalactic dust?

This object was selected as an i'-band dropout object, with i* = 21.8 ± 0.2 and z* = 19.2 ± 0.1. It has an absolute magnitude M1450 = -27.2 (H0 = 50 km s-1 Mpc-1, q0 = 0.5). The spectrum shows a strong and broad Lyα emission line, strong Lyα forest absorption lines with a mean continuum decrement DA = 0.91 and a Lyman limit system at z = 5.72. The spectrum also shows strong O I and Si IV emission lines similar to those of quasars at z ≲ 5, suggesting that these metals were produced at a redshift beyond 6. The lack of a Gunn-Peterson trough in the spectrum indicates that the universe is already highly ionized at z ∼ 5.8. Using a high-resolution spectrum in the Lyα forest region, we place a conservative upper limit on the optical depth because of the Gunn-Peterson effect of τ < 0.5 in regions of minimum absorption. The Lyα forest absorption in this object is much stronger than that in quasars at z ≲ 5. The object is unresolved in a deep image with excellent seeing, implying that it is unlensed. The black hole mass of this quasar is ∼3 × 109 M⊙ if we assume no lensing amplification and that it is radiating at the Eddington luminosity, implying that it resides in a very massive dark matter halo. The discovery of one quasar at M1450 < -27 in a survey area of 600 deg2 is consistent with an extrapolation of the observed luminosity function at lower redshifts. The abundance and evolution of such quasars can provide sensitive tests for models of quasar and galaxy formation.","lang":"eng"}]},{"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"abstract":[{"lang":"eng","text":"We compute the expected angular power spectrum of the cosmic far infrared background (FIRB).

The mass accretion rate, , onto quasar BHs is a free parameter of the models, which we constrain using the observed LFs. The accretion rate inferred from either the optical or X-ray data under these assumptions generally decreases as a function of cosmic time from z ≃ 4 to z ≃ 0. We find that a comparable accretion rate is inferred from the X-ray and optical LF only if the X-ray/optical flux ratio decreases with BH mass. Near z ≃ 0, drops to substantially sub-Eddington values at which advection-dominated accretion flows (ADAFs) exist. Such a decline of M, possibly followed by a transition to radiatively inefficient ADAFs, could explain both the absence of bright quasars in the local universe and the faintness of accreting BHs at the centers of nearby galaxies. We argue that a decline of the accretion rate of the quasar population is indeed expected in cosmological structure formation models.","lang":"eng"}],"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"citation":{"apa":"Haiman, Z., &#38; Menou, K.

At the limiting line flux ≈10^-19 ergs s^-1 cm^-2 arcsec^-2 of the Next Generation Space Telescope, several sufficiently massive halos, with velocity dispersions σ ≳ 120 km s^-1, would be visible per 4' × 4' field. The halos would have characteristic angular sizes of ≈10'', would be detectable in a broadband survey out to z ≈ 6-8, and would provide a direct probe of galaxies in the process of forming. They may be accompanied by He+ Lyα emission at the ≈10% level, but remain undetectable at other wavelengths.
