Galaxy And Mass Assembly (GAMA): Gas Fuelling of Spiral Galaxies in the Local Universe I. - The Effect of the Group Environment on Star Formation in Spiral Galaxies

M. W. Grootes, R. J. Tuffs, C. C. Popescu +20

Abridged - We quantify the effect of the galaxy group environment (for 12.5 < log(M_group/Msun) < 14.0) on the star formation rates of the (morphologically-selected) population of…

Galaxy-Galaxy Lensing in EAGLE: comparison with data from 180 square degrees of the KiDS and GAMA surveys

Marco Velliscig, Marcello Cacciato, Henk Hoekstra +14

We present predictions for the galaxy-galaxy lensing profile from the EAGLE hydrodynamical cosmological simulation at redshift z=0.18, in the spatial range 0.02 < R/(Mpc/h) < 2, an…

Implications of an updated ultraviolet background for the ionization mechanisms of intervening Ne VIII absorbers

Tanvir Hussain, Vikram Khaire, Raghunathan Srianand +2

Ne VIII absorbers seen in QSO spectra are useful tracers of warm ionized gas, when collisional ionization is the dominant ionization process. While photoionization by the ultraviol…

AGN-Host Connection at 0.5 < z < 2.5: A rapid evolution of AGN fraction in red galaxies during the last 10 Gyr

Tao Wang, D. Elbaz, D. M. Alexander +13

We explore the dependence of the incidence of moderate-luminosity ( erg s) AGNs and the distribution of their accretion rates on host color at 0.5 <…

On the galaxy-halo connection in the EAGLE simulation

Harry Desmond, Yao-Yuan Mao, Risa Wechsler +2

Empirical models of galaxy formation require assumptions about the correlations between galaxy and halo properties. These may be calibrated against observations or inferred from ph…

Molecular Gas in the Halo Fuels the Growth of a Massive Cluster Galaxy at High Redshift

B. H. C. Emonts, M. D. Lehnert, M. Villar-Martin +19

The largest galaxies in the Universe reside in galaxy clusters. Using sensitive observations of carbon-monoxide, we show that the Spiderweb Galaxy -a massive galaxy in a distant pr…
