MegaZ-LRG: A photometric redshift catalogue of one million SDSS Luminous Red Galaxies
Adrian Collister, Ofer Lahav, Chris Blake +14
We describe the construction of MegaZ-LRG, a photometric redshift catalogue of over one million luminous red galaxies (LRGs) in the redshift range 0.4 < z < 0.7 with limiting magni…
Cosmological baryonic and matter densities from 600,000 SDSS Luminous Red Galaxies with photometric redshifts
Chris Blake, Adrian Collister, Sarah Bridle +1
We analyze MegaZ-LRG, a photometric-redshift catalogue of Luminous Red Galaxies (LRGs) based on the imaging data of the Sloan Digital Sky Survey (SDSS) 4th Data Release. MegaZ-LRG,…
The distribution of red and blue galaxies in groups: an empirical test of the halo model
Adrian A. Collister, Ofer Lahav
The popular halo model predicts that the power spectrum of the galaxy fluctuations is simply the sum of the large scale linear halo-halo power spectrum and the weighted power spect…
ANNz: estimating photometric redshifts using artificial neural networks
Adrian A. Collister, Ofer Lahav
We introduce ANNz, a freely available software package for photometric redshift estimation using Artificial Neural Networks. ANNz learns the relation between photometry and redshif…
