Variability in Quasar Broad Absorption Line Outflows I. Trends in the Short-Term versus Long-Term Data
Daniel M. Capellupo, Fred Hamann, Joseph C. Shields +2
Broad absorption lines (BALs) in quasar spectra identify high velocity outflows that likely exist in all quasars and could play a major role in feedback to galaxy evolution. The va…
Time-dependent Radiation Transfer in the Internal Shock Model Scenario for Blazar Jets
Manasvita Joshi, Markus Boettcher
We describe the time-dependent radiation transfer in blazar jets, within the internal shock model. We assume that the central engine, which consists of a black hole and an accretio…
The fundamental plane of EDisCS galaxies - The effect of size evolution
R. P. Saglia, P. Sanchez-Blazquez, R. Bender +15
We study the evolution of spectral early-type galaxies in clusters, groups and the field up to redshift 0.9 using the EDisCS dataset. We measure Re, Ie, and sigma for 154 cluster a…
The DAFT/FADA survey. I.Photometric redshifts along lines of sight to clusters in the z=[0.4,0.9] interval
L. Guennou, C. Adami, M. P. Ulmer +20
As a contribution to the understanding of the dark energy concept, the Dark energy American French Team (DAFT, in French FADA) has started a large project to characterize statistic…
New Nuclear Physics for Big Bang Nucleosynthesis
Richard N. Boyd, Carl R. Brune, George M. Fuller +1
We discuss nuclear reactions which could play a role in Big Bang Nucleosynthesis (BBN). Most of these reactions involve lithium and beryllium isotopes and the rates for some of the…
Fermi Large Area Telescope and multi-wavelength observations of the flaring activity of PKS 1510-089 between 2008 September and 2009 June
LAT Collaboration
We report on the multi-wavelength observations of PKS 1510-089 (a flat spectrum radio quasar at z=0.361) during its high activity period between 2008 September and 2009 June. Durin…
