The X-ray Flux Distribution of Sagittarius A* as Seen by Chandra
J. Neilsen, S. Markoff, M. A. Nowak +11
We present a statistical analysis of the X-ray flux distribution of Sgr A* from the Chandra X-ray Observatory's 3 Ms Sgr A* X-ray Visionary Project (XVP) in 2012. Our analysis indi…
Unprecedented study of the broadband emission of Mrk 421 during flaring activity in March 2010
The MAGIC Collaboration, J. Aleksić, S. Ansoldi +251
A flare from the TeV blazar Mrk 421, occurring in March 2010, was observed for 13 consecutive days from radio to very high energy (VHE, E > 100 GeV) gamma-rays with MAGIC, VERITAS,…
Time-Variable Linear Polarization as a Probe of the Physical Conditions in the Compact Jets of Blazars
Alan P. Marscher
A single measurement of linear polarization of a nonthermal source provides direct information about the mean direction and level of ordering of the magnetic field. Monitoring of t…
Very Long Baseline polarimetry and the gamma-ray connection in Markarian 421 during the broadband campaign in 2011
R. Lico, M. Giroletti, M. Orienti +16
We analyzed data in polarized intensity obtained with the Very Long Baseline Array (VLBA) at twelve epochs (one observation per month from January to December 2011) at 15, 24, and…
Secondary Production as the Origin for the Cosmic Ray Positron Excess
M. Kruskal, S. P. Ahlen, G. Tarlé
The Alpha Magnetic Spectrometer has released high-precision data for cosmic rays, and has verified an excess of positrons relative to expectations from cosmic ray interactions in t…
Jet outflow and gamma-ray emission correlations in S5 0716+714
B. Rani, T. P. Krichbaum, A. P. Marscher +4
Using millimeter-very long baseline interferometry (VLBI) observations of the BL Lac object S5 0716+714 from August 2008 to September 2013, we investigate variations in the core fl…
The connection between the parsec-scale radio jet and gamma-ray flares in the blazar 1156+295
Venkatessh Ramakrishnan, Jonathan León-Tavares, Elizaveta A. Rastorgueva-Foi +30
The blazar 1156+295 was active at gamma-ray energies, exhibiting three prominent flares during the year 2010. Here, we present results using the combination of broadband (X-ray thr…
Comprehensive Monitoring of Gamma-ray Bright Blazars. I. Statistical Study of Optical, X-ray, and Gamma-ray Spectral Slopes
Karen E. Williamson, Svetlana G. Jorstad, Alan P. Marscher +21
We present -ray, X-ray, ultraviolet, optical, and near-infrared light curves of 33 -ray bright blazars over four years that we have been monitoring since 2008 August with mul…
The Outburst of the Blazar S40954+658 in March-April 2011
D. A. Morozova, V. M. Larionov, I. S. Troitsky +22
We present the results of optical (R band) photometric and polarimetric monitoring and Very Long Baseline Array (VLBA) imaging of the blazar S4 0954+658, along with Fermi and gamma…
A Continuum of H- to He-Rich Tidal Disruption Candidates With a Preference for E+A Galaxies
Iair Arcavi, Avishay Gal-Yam, Mark Sullivan +23
We present the results of a Palomar Transient Factory (PTF) archival search for blue transients which lie in the magnitude range between "normal" core-collapse and superluminous su…
Seed Photon Fields of Blazars in the Internal Shock Scenario
Manasvita Joshi, Alan P. Marscher, Markus Boettcher
We extend our approach of modeling spectral energy distribution (SED) and lightcurves of blazars to include external Compton (EC) emission due to inverse Compton scattering of an e…
A Link Between X-ray Emission Lines and Radio Jets in 4U 1630-47?
Joseph Neilsen, Mickael Coriat, Rob Fender +5
Recently, Diaz Trigo et al. reported an XMM-Newton detection of relativistically Doppler-shifted emission lines associated with steep-spectrum radio emission in the stellar-mass bl…
MAGIC gamma-ray and multifrequency observations of flat spectrum radio quasar PKS 1510-089 in early 2012
MAGIC Collaboration, J. Aleksić, S. Ansoldi +218
Among more than fifty blazars detected in very high energy (VHE, E>100GeV) gamma-rays, only three belong to the subclass of Flat Spectrum Radio Quasars (FSRQs). MAGIC observed FSRQ…
