High energy emission from the nebula around the Black Widow binary system containing millisecond pulsar B1957+20
W. Bednarek, J. Sitarek
The features of pulsed -ray emission from classical and millisecond pulsars indicate that the high energy radiation processes in their inner magnetospheres occur in a similar wa…
Observations of the magnetars 4U 0142+61 and 1E 2259+586 with the MAGIC telescopes
The MAGIC Collaboration, J. Aleksić, L. A. Antonelli +153
Magnetars are an extreme, highly magnetized class of isolated neutron stars whose large X-ray luminosity is believed to be driven by their high magnetic field. In this work we stud…
The Simultaneous Low State Spectral Energy Distribution of 1ES 2344+514 from Radio to Very High Energies
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +191
[Abridged] Context. To construct and interpret the spectral energy distribution (SED) of BL Lacertae objects, simultaneous broad-band observations are mandatory. Aims. We present t…
Binaries with the eyes of CTA
J. M. Paredes, W. Bednarek, P. Bordas +20
The binary systems that have been detected in gamma rays have proven very useful to study high-energy processes, in particular particle acceleration, emission and radiation reproce…
GeV-TeV gamma-rays and neutrinos from the Nova V407 Cygni
Julian Sitarek, Włodek Bednarek
The Fermi-LAT telescope has unexpectedly discovered GeV gamma-ray emission from the symbiotic Nova V407 Cygni. We investigate the radiation processes due to electrons and hadrons a…
MAGIC observations of the giant radio galaxy M87 in a low-emission state between 2005 and 2007
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +155
We present the results of a long M87 monitoring campaign in very high energy -rays with the MAGIC-I Cherenkov telescope. We aim to model the persistent non-thermal jet emission…
On the origin of sub-TeV gamma-ray pulsed emission from rotating neutron stars
W. Bednarek
Intriguing sub-TeV tails in the pulsed -ray emission from the Crab pulsar have been recently discovered by the MAGIC and VERITAS Collaborations. They were not clearly predicted…
High energy gamma-ray emission from compact galactic sources in the context of observations with the next generation Cherenkov Telescope Arrays
W. Bednarek
The observational progress in the -ray astronomy in the last few years has led to the discovery of more than a thousand sources at GeV energies and more than a hundred sources a…
Gamma-rays from electrons accelerated by rotating magnetized White Dwarfs in Globular Clusters
W. Bednarek
Recently a substantial part of globular cluster population has been established as GeV gamma-ray sources by the Fermi-LAT telescope. We investigate possible production of the high…
Detection of VHE γ-rays from HESS J0632+057 during the 2011 February X-ray outburst with the MAGIC Telescopes
The MAGIC Collaboration, J. Aleksić, E. A. Alvarez +158
The very high energy (VHE) γ-ray source HESS J0632+057 has recently been confirmed to be a γ-ray binary. The optical counterpart is the Be star MWC 148, and a compact object of unk…
Discovery of VHE gamma-rays from the blazar 1ES 1215+303 with the MAGIC Telescopes and simultaneous multi-wavelength observations
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +164
Context. We present the discovery of very high energy (VHE, E > 100GeV) gamma-ray emission from the BL Lac object 1ES 1215+303 by the MAGIC telescopes and simultaneous multi-wavele…
Morphological and spectral properties of the W51 region measured with the MAGIC telescopes
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +157
The W51 complex hosts the supernova remnant W51C which is known to interact with the molecular clouds in the star forming region W51B. In addition, a possible pulsar wind nebula CX…
Discovery of VHE gamma-ray emission from the BL Lac object B3 2247+381 with the MAGIC telescopes
The MAGIC Collaboration, J. Aleksić, E. A. Alvarez +156
We study the non-thermal jet emission of the BL Lac object B3 2247+381 during a high optical state. The MAGIC telescopes observed the source during 13 nights between September 30th…
