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…

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…

Suzaku and Multi-wavelength Observations of OJ 287 during the Periodic Optical Outburst in 2007

Hiromi Seta, Naoki Isobe, Makoto S. Tashiro +10

Suzaku observations of the blazar OJ 287 were performed in 2007 April 10--13 and November 7--9. They correspond to a quiescent and a flaring state, respectively. The X-ray spectra…

Search for VHE -ray emission from the globular cluster M13 with the MAGIC telescope

MAGIC Collaboration

Based on MAGIC observations from June and July 2007, we have obtained an integral upper limit to the VHE energy emission of the globular cluster M13 of $F(E>200 \textrm{GeV})<5.1\t…
