Simultaneous multi-frequency observation of the unknown redshift blazar PG 1553+113 in March-April 2008
MAGIC Collaboration, J. Aleksić, H. Anderhub +161
The blazar PG 1553+113 is a well known TeV gamma-ray emitter. In this paper, we determine its spectral energy distribution using simultaneous multi-frequency data in order to study…
Simultaneous Multiwavelength observation of Mkn 501 in a low state in 2006
The MAGIC Collaboration, H. Anderhub, R. Sato +4
We present results of the multiwavelength campaign on the TeV blazar Mkn 501 performed in 2006 July, including MAGIC for the VHE gamma-ray band and Suzaku for the X-ray band. A VHE…
Radio Imaging of the Very-High-Energy Gamma-Ray Emission Region in the Central Engine of a Radio Galaxy
The VERITAS Collaboration, the VLBA 43 GHz M 87 Monitoring Team, the H. E. S. S. Collaboration +1
The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particle…
Simultaneous Multiwavelength Observations of Markarian 421 During Outburst
The VERITAS Collaboration, I. de la Calle Perez, A. Ibarra +2
We report on the results of two coordinated multiwavelength campaigns that focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These campaigns obtained UV and X…
First bounds on the VHE gamma-ray emission from isolated Wolf-Rayet binary systems
Diego F. Torres, Javier Rico, Vincenzo Vitale
Different theoretical models predict VHE gamma-ray emission to arise in tight binary star systems (high mass-loss and high wind speeds), which has not been confirmed experimentally…
The June 2008 flare of Markarian 421 from optical to TeV energies
R. M. Wagner, I. Donnarumma, J. Grube +6
We present optical to very-high energy (VHE) gamma-ray observations of Mrk 421 between 2008 May 24 and June 23. A high-energy (HE) gamma-ray signal was detected by AGILE-GRID durin…
