Star Formation in AEGIS Field Galaxies since z = 1.1: The Dominance of Gradually Declining Star Formation, and the Main Sequence of Star-forming Galaxies
We analyze star formation (SF) as a function of stellar mass (M*) and redshift z in the All-Wavelength Extended Groth Strip International Survey. For 2905 field galaxies, complete to 1010(1010.8) M☉…

Selection of active galactic nuclei (AGNs) in the infrared facilitates the discovery of AGNs whose optical emission is extinguished by dust. In this paper, we use the Spitzer Space Telescope First…
The All-Wavelength Extended Groth Strip International Survey (AEGIS) Data Sets
- M. Davis, P. Guhathakurta, R. Yan
- Physics
- 15 July 2006
In this the first of a series of Letters, we present a panchromatic data set in the Extended Groth Strip region of the sky. Our survey, the All-Wavelength Extended Groth Strip International Survey…
THE GEMINI CLUSTER ASTROPHYSICS SPECTROSCOPIC SURVEY (GCLASS): THE ROLE OF ENVIRONMENT AND SELF-REGULATION IN GALAXY EVOLUTION AT z ∼ 1
We evaluate the effects of environment and stellar mass on galaxy properties at 0.85 9.3 the well-known correlations between environment and properties such as star-forming fraction (fSF), star…
Evidence for Significant Growth in the Stellar Mass of Brightest Cluster Galaxies over the Past 10 Billion Years
- C. Lidman, J. Suherli, T. Webb
- Physics
- 25 August 2012
Using new and published data, we construct a sample of 160 brightest cluster galaxies (BCGs) spanning the redshift interval 0.03 < z < 1.63. We use this sample, which covers 70 per cent of the…
DISCOVERY OF A RICH CLUSTER AT z = 1.63 USING THE REST-FRAME 1.6 μm “STELLAR BUMP SEQUENCE” METHOD
- A. Muzzin, G. Wilson, A. Rettura
- Physics
- 24 January 2013
We present a new two-color algorithm, the “Stellar Bump Sequence” (SBS), that is optimized for robustly identifying candidate high-redshift galaxy clusters in combined wide-field optical and…
The ROSAT Deep Survey - VI. X-ray sources and Optical identifications of the Ultra Deep Survey
- I. Lehmann, G. Hasinger, G. Wilson
- Physics
- 22 March 2001
The ROSAT Deep Surveys in the direction of the Lockman Hole are the most sensitive X-ray surveys performed with the ROSAT satellite. About 70-80% of the X-ray background has been resolved into…
Star Formation History since z = 1.5 as Inferred from Rest-Frame Ultraviolet Luminosity Density Evolution
We investigate the evolution of the universal rest-frame ultraviolet luminosity density from z = 1.5 to the present. We analyze an extensive sample of multicolor data (U, BAB, VAB = 24.5) plus…
Evidence for a change in the dominant satellite galaxy quenching mechanism at z = 1.
We present an analysis of galaxies in groups and clusters at 0.8 10(10.3) M-circle dot, we find f(convert) similar to 0.4 in the groups and similar to 0.6 in the clusters, similar to comparable…
