In the six billion years between redshifts z = 1 and z = 0.1, galaxies change due to the aging of their stellar populations, the formation of new stars, and mergers with other galaxies. Here I explore the relative importance of these various effects, finding that mergers and other processes are unlikely to convert more than 10% of the blue galaxy sequence into red galaxies in that time period. I compare the galaxy population at redshift z ~ 0.1 from the Sloan Digital Sky Survey (SDSS) to the… 
THE z < 1.2 ?> OPTICAL LUMINOSITY FUNCTION FROM A SAMPLE OF ∼410,000 GALAXIES IN BOÖTES
Using a sample of ∼410,000 galaxies to a depth of I AB = 24 ?> over 8.26 deg2 in the Boötes field (∼10 times larger than the z ∼ 1 ?> luminosity function (LF) studies in the prior literature), we
The Evolving Luminosity Function of Red Galaxies
We trace the assembly history of red galaxies since z = 1 by measuring their evolving space density with the B-band luminosity function. Our sample of 39,599 red galaxies, selected from 6.96 deg2 of
THE ASSEMBLY HISTORIES OF QUIESCENT GALAXIES SINCE z = 0.7 FROM ABSORPTION LINE SPECTROSCOPY
We present results from modeling the optical spectra of a large sample of quiescent galaxies between 0.1 < z < 0.7 from the Sloan Digital Sky Survey (SDSS) and the AGN and Galaxy Evolution Survey
The DEEP2 Galaxy Redshift Survey: environments of post-starburst galaxies at z∼ 0.1 and ∼0.8
Post-starburst (also known as K+A) galaxies exhibit spectroscopic signatures indicating that their star formation was recently quenched; they are candidates for galaxies in transition from a
The DEEP2 galaxy redshift survey: the evolution of the blue fraction in groups and the field
We explore the behaviour of the blue galaxy fraction over the redshift range 0.75 z 1.3 in the DEEP2 Survey, both for field galaxies and for galaxies in groups. The primary aim is to determine the
Evolutionary paths to and from the red sequence: star formation and H i properties of transition galaxies at z∼ 0
We investigate the properties of galaxies between the blue and the red sequence (i.e. the transition region, 4.5 < NUV - H < 6 mag) by combining ultraviolet (UV) and near-infrared imaging to 21-cm H
The VIMOS Public Extragalactic Redshift Survey (VIPERS): - A quiescent formation of massive red-sequence galaxies over the past 9 Gyr
We explore the evolution of the Colour-Magnitude Relation (CMR) and Luminosity Function (LF) at 0.4 10^11 M_sun) and expeditious RS formation over a short period of ~1.5 Gyr starting before z=1. This
Galaxy evolution in the high-redshift, colour-selected cluster RzCS 052 at z= 1.02
We present deep I and z' imaging of the colour-selected cluster RzCS 052 and study the colour-magnitude relation of this cluster, its scatter, the morphological distribution on the red sequence, the
GALAXY GROWTH BY MERGING IN THE NEARBY UNIVERSE
We measure the mass growth rate by merging for a wide range of galaxy types. We present the small-scale (0.014 h−170 Mpc < r < 11 h70−1 Mpc) projected cross-correlation functions w(rp) of galaxy
The DEEP2 Galaxy Redshift Survey: the role of galaxy environment in the cosmic star formation history
Using galaxy samples drawn from the Sloan Digital Sky Survey and the DEEP2 Galaxy Redshift Survey, we study the relationship between star formation and environment at z ∼ 0.1 and 1. We estimate the
