Probing the bias of radio sources at high redshift

Author: Passmoor, S ; Cress, C ; Faltenbacher, A ; Johnston, R ; Smith, M ; Ratsimbazafy, A ; Hoyle, B Date: Nov 2012 The relationship between the clustering of dark matter and that of luminous matter is often described using the bias parameter. Here, we provide a new method to probe the bias of intermediate-to-high-redshift radio continuum sources for which ... Read more
Reconstructing the velocity field beyond the local universe

Author: Johnston, R ; Bacon, D ; Teodoro, LFA ; Nichol, RC ; Warren, MS ; Cress, C Date: Oct 2014 We present a maximum probability approach to reconstructing spatial maps of the peculiar velocity field at redshifts z ~ 0.1, where the velocities have been measured from distance indicators (DI) such as D(sub n) - s relations or Tully–Fisher. ...
