The 21 Centimeter Background from the Cosmic Dark Ages: Minihalos and the Intergalactic Medium before Reionization
Paul R. Shapiro, Kyungjin Ahn, Marcelo A. Alvarez +3
The H atoms inside minihalos (i.e. halos with virial temperatures T_vir < 10^4 K, in the mass range roughly from 10^4 M_sun to 10^8 M_sun) during the cosmic dark ages in a LambdaCD…
Gas Rich Mergers in Disk Formation
Chris B. Brook, Vincent Veilleux, Daisuke Kawata +2
In order to explain disk galaxy formation within the hierarchical structure formation, it seems that gas rich mergers must play an important role. We review here our previous studi…
Understanding the Equilibrium Structure of CDM Halos
Paul R. Shapiro, Kyungjin Ahn, Marcelo Alvarez +2
N-body simulations find a universal structure for the halos which result from the nonlinear growth of Gaussian-random-noise density fluctuations in the CDM universe. This talk summ…
HI Detection in two Dwarf S0 Galaxies in Nearby Groups: ESO384-016 and NGC 59
Sylvie F. Beaulieu, Kenneth C. Freeman, Claude Carignan +2
An \hi survey of 10 dE/dS0 galaxies in the nearby Sculptor and Centaurus A groups was made using the Australia Telescope Compact Array (ATCA). The observed galaxies have accurate d…
The 21-cm Background from the Cosmic Dark Ages: Minihalos and the Intergalactic Medium before Reionization
Kyungjin Ahn, Paul R. Shapiro, Marcelo A. Alvarez +3
The H atoms inside minihalos (i.e. halos with virial temperatures T_vir < 10^4 K, in the mass range roughly from 10^4 M_sun to 10^8 M_sun) during the cosmic dark ages in a LCDM uni…
The Evolving Structure of Galactic Disks
Hugo Martel, Chris Brook, Sean McGee +2
Observations suggest that the structural parameters of disk galaxies have not changed greatly since redshift 1. We examine whether these observations are consistent with a cosmolog…
