Journal ArticleDOI
Cosmology: small scale issues revisited
TL;DR: In this paper, the authors consider the implications for cold vs. various varieties of warm dark matter (WDM) for galaxy formation, and the current evidence appears to be consistent with the standard LambdaCDM, although improving data may point toward a rather tepid version of LambdaWDM.
Journal ArticleDOI
Implications of Spikes in the Redshift Distribution of $z\sim3$ Galaxies
Risa H. Wechsler,Michael A. K. Gross,Michael A. K. Gross,Joel R. Primack,George R. Blumenthal,George R. Blumenthal,Avishai Dekel,Avishai Dekel +7 more
TL;DR: In this article, the authors examined the likelihood of such a spike in the redshift distribution within a suite of models for the evolution of structure in the Universe, including models with Omega=1 (SCDM and CHDM) and with Omega = 0.4-0.5 (LCDM and OCDM).
Journal ArticleDOI
Concentrations of Dark Halos from their Assembly Histories
TL;DR: In this article, the relation between the density profiles of dark matter halos and their mass assembly histories was studied using a statistical sample of halos in a high-resolution N-body simulation of the LCDM cosmology.
Journal ArticleDOI
Caught in the Act: Gas and Stellar Velocity Dispersions in a Fast Quenching Compact Star-Forming Galaxy at z~1.7
Guillermo Barro,Sandra M. Faber,Avishai Dekel,Camilla Pacifici,Pablo G. Pérez-González,Elisa Toloba,David C. Koo,Jonathan R. Trump,Shigeki Inoue,Yicheng Guo,F. S. Liu,Joel R. Primack,Anton M. Koekemoer,Gabriel B. Brammer,Antonio Cava,Nicolás Cardiel,Daniel Ceverino,Carmen Eliche,Jerome J. Fang,Steven L. Finkelstein,Dale D. Kocevski,Rachael Livermore,Elizabeth J. McGrath +22 more
TL;DR: In this paper, Keck I MOSFIRE spectroscopy in the Y and H bands of GDN-8231, a massive, compact, star-forming galaxy at a redshift of z ~ 1.7 is presented.
Journal ArticleDOI
Implications of spikes in the redshift distribution of z ~ 3 galaxies
Risa H. Wechsler,Michael A. K. Gross,Michael A. K. Gross,Joel R. Primack,George R. Blumenthal,George R. Blumenthal,Avishai Dekel +6 more
TL;DR: In this article, the authors examined the likelihood of such a spike in the redshift distribution of Lyman-break objects (LBOs) within a suite of models for the evolution of structure in the universe, including models with Ω = 1 (a standard cold dark matter [SCDM] and a cold plus hot dark matter model [CHDM]).
