Observational Limits on Type 1 AGN Accretion Rate in COSMOS
Jonathan R. Trump, Chris D. Impey, Brandon C. Kelly +13
We present black hole masses and accretion rates for 182 Type 1 AGN in COSMOS. We estimate masses using the scaling relations for the broad Hb, MgII, and CIV emission lines in the…
The Chandra COSMOS Survey, I: Overview and Point Source Catalog
Martin Elvis, Francesca Civano, Cristian Vignali +40
The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra} program that has imaged the central 0.5 sq.deg of the COSMOS field (centered at 10h, +02deg) with an effective exp…
Strongly Variable z=1.48 FeII and MgII Absorption in the Spectra of z=4.05 GRB 060206
H. Hao, K. Z. Stanek, A. Dobrzycki +9
We report on the discovery of strongly variable FeII and MgII absorption lines seen at z=1.48 in the spectra of the z=4.05 GRB 060206 obtained between 4.13 to 7.63 hours (observer…
"Anomalous" Optical GRB Afterglows are Common: Two z~4 Bursts, GRB 060206 and 060210
K. Z. Stanek, X. Dai, J. L. Prieto +9
We report on two recent z~4 gamma-ray bursts (GRBs), GRB 060206 and GRB 060210, for which we have obtained well-sampled optical light curves. Our data, combined with early optical…
Detecting a physical difference between the CDM halos in simulation and in nature
Weike Xiao, Chang Peng, Xianfeng Ye +1
Numerical simulation is an important tool to help us understand the process of structure formation in the universe. However many simulation results of cold dark matter (CDM) halos…
A Physical Bias in Cosmological Simulations
Weike Xiao, Zhengfan Sun, Heng Hao
Numerical simulation plays an important role in the study of structure formation of the universe. However, the mass resolution in current simulations is still poor. Due to technica…
