DESI 2024 II: Sample Definitions, Characteristics, and Two-point Clustering Statistics
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present the samples of galaxies and quasars used for DESI 2024 cosmological analyses, drawn from the DESI Data Release 1 (DR1). We describe the construction of large-scale struc…
Modeling the Ages and Chemical Abundances of Elliptical Galaxies
Nicole Marcelina Gountanis, David H. Weinberg, Aliza G. Beverage +3
Spectroscopic studies of elliptical galaxies show that their stellar population ages, mean metallicity, and -enhancement traced by [Mg/Fe] all increase with galaxy stellar mass…
Carbon and Iron Deficiencies in Quiescent Galaxies at z=1-3 from JWST-SUSPENSE: Implications for the Formation Histories of Massive Galaxies
Aliza G. Beverage, Martje Slob, Mariska Kriek +20
We present the stellar metallicities and multi-element abundances (C, Mg, Si, Ca, Ti, Cr, and Fe) of 15 massive (log ) quiescent galaxies at z=1-3, derived fro…
DESI 2024 III: Baryon Acoustic Oscillations from Galaxies and Quasars
DESI Collaboration, A. G. Adame, J. Aguilar +193
We present the DESI 2024 galaxy and quasar baryon acoustic oscillations (BAO) measurements using over 5.7 million unique galaxy and quasar redshifts in the range 0.1<z<2.1. Divided…
DESI 2024 VI: Cosmological Constraints from the Measurements of Baryon Acoustic Oscillations
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present cosmological results from the measurement of baryon acoustic oscillations (BAO) in galaxy, quasar and Lyman- forest tracers from the first year of observations from t…
DESI 2024 IV: Baryon Acoustic Oscillations from the Lyman Alpha Forest
DESI Collaboration, A. G. Adame, J. Aguilar +196
We present the measurement of Baryon Acoustic Oscillations (BAO) from the Lyman- (Ly) forest of high-redshift quasars with the first-year dataset of the Dark Energy Spectrosc…
Galaxies in a Simulated CDM Universe II: Observable Properties and Constraints on Feedback
Dušan Kereš, Neal Katz, Romeel Dave +2
We compare the properties of galaxies that form in a cosmological simulation without strong feedback to observations at z=0. We confirm previous findings that models without strong…
The Growth of Central and Satellite Galaxies in Cosmological Smoothed Particle Hydrodynamics Simulations
Vimal Simha, David H. Weinberg, Romeel Dave +3
We examine the accretion and merger histories of central and satellite galaxies in a smoothed particle hydrodynamics (SPH) cosmological simulation that resolves galaxies down to 7e…
Dark Matter Halos of Disk Galaxies: Constraints from the Tully-Fisher Relation
Oleg Y. Gnedin, David H. Weinberg, James Pizagno +2
We investigate structural properties of dark matter halos of disk galaxies in LCDM cosmology, using a well-defined sample of 81 disk-dominated galaxies from the SDSS redshift surve…
Photoionization Feedback in Low--Mass Galaxies at High Redshift
Mark Dijkstra, Zoltan Haiman, Martin J. Rees +1
The cosmic ultraviolet (UV) ionizing background impacts the formation of dwarf galaxies in the low-redshift universe (z=3) by suppressing gas infall into galactic halos with circul…
Comparing Simulations and Observations of the Lyman-Alpha Forest I. Methodology
C. E. Petry, C. D. Impey, N. Katz +2
We describe techniques for comparing spectra extracted from cosmological simulations and observational data, using the same methodology to link Lyman-alpha properties derived from…
Metal Enrichment of the Intergalactic Medium in Cosmological Simulations
Anthony Aguirre, Lars Hernquist, Joop Schaye +3
Observations have established that the diffuse intergalactic medium (IGM) at z ~ 3 is enriched to ~0.1-1% solar metallicity and that the hot gas in large clusters of galaxies (ICM)…
Metal Enrichment of the Intergalactic Medium at z=3 by Galactic Winds
Anthony Aguirre, Lars Hernquist, Joop Schaye +3
Studies of quasar absorption lines reveal that the low density intergalactic medium at z ~ 3 is enriched to 0.001-0.01 solar metallicity. This enrichment may have occurred in an ea…
