X-Ray Groups of Galaxies in the Aegis Deep and Wide Fields
G. Erfanianfar, A. Finoguenov, M. Tanaka +19
We present the results of a search for extended X-ray sources and their corresponding galaxy groups from 800-ks Chandra coverage of the All-wavelength Extended Groth Strip Internat…
Towards a resolved Kennicutt-Schmidt law at high redshift
J. Freundlich, F. Combes, L. J. Tacconi +16
Massive galaxies in the distant Universe form stars at much higher rates than today. Although direct resolution of the star forming regions of these galaxies is still a challenge,…
The metallicity dependence of the CO {\rightarrow} H_2 conversion factor in z>1 star forming galaxies
R. Genzel, L. J. Tacconi, F. Combes +20
We use the first systematic samples of CO millimeter emission in z>1 'main-sequence' star forming galaxies (SFGs) to study the metallicity dependence of the conversion factor αCO,…
A Study of the Gas-Star Formation Relation over Cosmic Time
R. Genzel, L. J. Tacconi, J. Gracia-Carpio +19
We use the first systematic data sets of CO molecular line emission in z~1-3 normal star forming galaxies for a comparison of the dependence of galaxy-averaged star formation rates…
High molecular gas fractions in normal massive star forming galaxies in the young Universe
L. J. Tacconi, R. Genzel, R. Neri +19
Stars form from cold molecular interstellar gas. Since this is relatively rare in the local Universe, galaxies like the Milky Way form only a few new stars per year. Typical massiv…
