Multi-waveband Emission Maps of Blazars

Alan Marscher, Svetlana G. Jorstad, Valeri M. Larionov +2

We are leading a comprehensive multi-waveband monitoring program of 34 gamma-ray bright blazars designed to locate the emission regions of blazars from radio to gamma-ray frequenci…

On The Origin Of The Mass-Metallicity Relation For GRB Host Galaxies

Daniel Kocevski, Andrew A. West

We investigate the nature of the mass-metallicity (M-Z) relation for long gamma-ray burst (LGRB) host galaxies. Recent studies suggest that the M-Z relation for local LGRB host gal…

Optical Spectral Variability of the Very-High-Energy Gamma-Ray Blazar 1ES 1011+496

M. Boettcher, B. Hivick, J. Dashti +10

We present results of five years of optical (UBVRI) observations of the very-high-energy gamma-ray blazar 1ES 1011+496 at the MDM Observatory. We calibrated UBVRI magnitudes of fiv…

Flaring Behavior of the Quasar 3C~454.3 across the Electromagnetic Spectrum

Svetlana G. Jorstad, Alan P. Marscher, Valeri M. Larionov +29

We analyze the behavior of the parsec-scale jet of the quasar 3C~454.3 during pronounced flaring activity in 2005-2008. Three major disturbances propagated down the jet along diffe…
