The X-ray to optical-UV luminosity ratio of X-ray selected Type 1 AGN in XMM-COSMOS
E. Lusso, A. Comastri, C. Vignali +29
We present a study of the X-ray to optical properties of a sample of 545 X-ray selected Type 1 AGN, from the XMM-COSMOS survey, over a wide range of redshifts ($0.04<\z<4.25$) and…
A catalog of Kazarian galaxies
M. A. Kazarian, V. Zh. Adibekyan, B. McLean +2
The entire Kazarian galaxies (KG) catalog is presented which combines extensive new measurements of their optical parameters with a literature and database search. The measurements…
A candidate redshift z ~ 10 galaxy and rapid changes in that population at an age of 500 Myr
R. J. Bouwens, G. D. Illingworth, I. Labbe +9
Searches for very-high-redshift galaxies over the past decade have yielded a large sample of more than 6,000 galaxies existing just 900-2,000 million years (Myr) after the Big Bang…
On the Stellar Populations and Evolution of Star-Forming Galaxies at 6.3 < z < 8.6
Steven L. Finkelstein, Casey Papovich, Mauro Giavalisco +4
We study the physical characteristics of galaxies at 6.3 < z < 8.6, selected from deep near-infrared imaging with the Wide Field Camera 3 (WFC3) on board the Hubble Space Telescope…
The Rise and Fall of Passive Disk Galaxies: Morphological Evolution Along the Red Sequence Revealed by COSMOS
K. Bundy, C. Scarlata, C. M. Carollo +13
The increasing abundance of passive "red-sequence" galaxies since z=1-2 is mirrored by a coincident rise in the number of galaxies with spheroidal morphologies. In this paper, howe…
A Multiwavelength Study of a Sample of 70 micron Selected Galaxies in the COSMOS Field I: Spectral Energy Distributions and Luminosities
Jeyhan S. Kartaltepe, D. B. Sanders, E. Le Floc'h +26
We present a large robust sample of 1503 reliable and unconfused 70microm selected sources from the multiwavelength data set of the Cosmic Evolution Survey (COSMOS). Using the Spit…
