Magic constraints on Gamma-ray emission from Cygnus X-3
J. Aleksić, L. A. Antonelli, P. Antoranz +156
Cygnus X-3 is a microquasar consisting of an accreting compact object orbiting around a Wolf-Rayet star. It has been detected at radio frequencies and up to high-energy gamma rays…
Gamma-ray excess from a stacked sample of high- and intermediate-frequency peaked blazars observed with the MAGIC telescope
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +147
Between 2004 and 2009 a sample of 28 X-ray selected high- and intermediate-frequency peaked blazars with a X-ray flux larger than 2 uJy at 1 keV in the redshift range from 0.018 to…
MAGIC TeV Gamma-Ray Observations of Markarian 421 during Multiwavelength Campaigns in 2006
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +145
The Major Atmospheric Gamma Imaging Cerenkov (MAGIC) telescope participated in three multiwavelength (MWL) campaigns, observing the blazar Markarian (Mkn) 421 during the nights of…
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…
MAGIC Gamma-ray Telescope Observation of the Perseus Cluster of Galaxies: implications for cosmic rays, dark matter, and NGC1275
The MAGIC Collaboration, J. Aleksić, L. A. Antonelli +152
The Perseus galaxy cluster was observed by the MAGIC Cherenkov telescope for a total effective time of 24.4 hr during 2008 November and December. The resulting upper limits on the…
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…
Upper Limits on the VHE gamma-ray Emission from the Willman 1 Satellite Galaxy with the MAGIC telescope
MAGIC Collaboration, E. Aliu
We present the result of the observation of the ultrafaint dwarf galaxy Willman 1 performed with the 17 m MAGIC telescope during 15.5 hr between March and May 2008. No significant…
Observation of Pulsed Gamma-rays Above 25 GeV from the Crab Pulsar with MAGIC
The MAGIC Collaboration, E. Aliu
One fundamental question about pulsars concerns the mechanism of their pulsed electromagnetic emission. Measuring the high-end region of a pulsar's spectrum would shed light on thi…
First bounds on the high-energy emission from isolated Wolf-Rayet binary systems
MAGIC Collaboration, E. Aliu
High-energy gamma-ray emission is theoretically expected to arise in tight binary star systems (with high mass loss and high velocity winds), although the evidence of this relation…
VHE Gamma-Ray Observation of the Crab Nebula and its Pulsar with the MAGIC telescope
MAGIC Collaboration, J. Albert
We report about very high energy (VHE) gamma-ray observations of the Crab Nebula with the MAGIC telescope. The gamma-ray flux from the nebula was measured between 60 GeV and 9 TeV.…
Discovery of very high energy gamma-ray emission from the low-frequency peaked BL Lacertae object BL Lacertae
MAGIC Collaboration, J. Albert
The MAGIC collaboration observed BL Lacertae for 22.2 hr during 2005 August to December and for 26 hr during 2006 July to September. The source is the historical prototype and epon…
