The Spatial Distribution of Satellite Galaxies
We use the first Millennium Run simulation (MRS) to investigate the spatial locations of the satellites of relatively isolated host galaxies. The stellar masses of the MRS hosts span a range of 10.3 6 log10 [M∗/M⊙] 6 11.5, and host-satellite systems were selected via typical redshift space proximity criteria. The 3-D locations of the MRS satellites are well-fitted by a combination of a Navarro,...
متن کاملThe Spatial Distribution Function of Galaxies at High Redshift
This is the first exploration of the galaxy distribution function at redshifts greater than about 0.1. Redshifts are based on the North and South GOODS Catalogs. In each catalog we examine clustering in the two redshift bands 0.47 ≤ z ≤ 0.8 and 0.9 ≤ z ≤ 1.5. The mean redshifts of the samples in these bands are about 0.6 and 1.1. Our main result is that at these redshifts the galaxy spatial dis...
متن کاملAlma Redshifts of Millimeter-selected Galaxies from the Spt Survey: the Redshift Distribution of Dusty Star-forming Galaxies
Using the Atacama Large Millimeter/submillimeter Array (ALMA), we have conducted a blind redshift survey in the 3mm atmospheric transmission window for 26 strongly lensed dusty starforming galaxies (DSFGs) selected with the South Pole Telescope (SPT). The sources were selected to have S1.4mm>20 mJy and a dust-like spectrum and, to remove low-z sources, not have bright radio (S843MHz < 6mJy) or ...
متن کاملHigh-redshift, Restframe Far-infrared Selected Galaxies
I discuss our current understanding of the properties and nature of high redshift, far-infrared luminous galaxies selected through their observedframe submillimeter emission.
متن کاملAnisotropies in the Distribution of Satellite Galaxies
We find that satellites of isolated disk galaxies at projected radii between 300 and 500 kpc are distributed asymmetrically about the parent galaxy and aligned preferentially with the disk minor axis. The dynamical timescale at these radii is sufficiently long that the shape of this distribution must reflect the formation history of the outer halo rather than its internal evolution. We also fin...
