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…
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…
First Neutrino Point-Source Results From the 22-String IceCube Detector
IceCube Collaboration, R. Abbasi
We present new results of searches for neutrino point sources in the northern sky, using data recorded in 2007-08 with 22 strings of the IceCube detector (approximately one-fourth…
Probing the ATIC peak in the cosmic-ray electron spectrum with H.E.S.S
H. E. S. S. Collaboration, :, F. Aharonian
The measurement of an excess in the cosmic-ray electron spectrum between 300 and 800 GeV by the ATIC experiment has - together with the PAMELA detection of a rise in the positron f…
Determination of the Atmospheric Neutrino Flux and Searches for New Physics with AMANDA-II
The IceCube Collaboration
The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100 GeV to 10 TeV ene…
