Multifrequency Observations of the Gamma-Ray Blazar 3C 279 in Low-State during Integral AO-1
W. Collmar, M. Böttcher, V. Burwitz +19
We report first results of a multifrequency campaign from radio to hard X-ray energies of the prominent gamma-ray blazar 3C 279 during the first year of the INTEGRAL mission. The v…
Quasars and Narrow-Line Seyfert 1s: Trends and Selection Effects
Joseph C. Shields, Anca Constantin
The SDSS has opened a new era for the study of AGN spectroscopic properties and how these depend on luminosity and time. In this presentation we review some of the current issues a…
Coordinated Multiwavelength Observations and Spectral Variability Modeling of Gamma-Ray Blazars
M. Boettcher
Our recent progress on time-dependent modeling of the multiwavelength spectra and variability of blazars with leptonic and hadronic jet models is reviewed. Special emphasis is plac…
The diagnostic power of X-ray emission lines in GRBs
M. Boettcher
Absorption and reprocessing of Gamma-ray burst radiation in the environment of cosmological GRBs can be used as a powerful probe of the elusive nature of their progenitors. Althoug…
Magnetic Bubbles in Galaxy Clusters
B. R. McNamara
I discuss Chandra X-ray Observatory measurements of cavities in galaxy clusters and their implications for heating the intracluster gas. The emerging paradigm for cooling flows has…
