Optimized dark matter searches in deep observations of Segue 1 with MAGIC
J. Aleksić, S. Ansoldi, L. A. Antonelli +156
We present the results of stereoscopic observations of the satellite galaxy Segue 1 with the MAGIC Telescopes, carried out between 2011 and 2013. With almost 160 hours of good-qual…
Modulated Gamma-ray emission from compact millisecond pulsar binary systems
W. Bednarek
A significant amount of the millisecond pulsars has been discovered within binary systems. In several such binary systems the masses of the companion stars have been derived allowi…
MAGIC upper limits on the GRB 090102 afterglow
MAGIC Collaboration, J. Aleksić, S. Ansoldi +160
Indications of a GeV component in the emission from GRBs are known since the EGRET observations during the 1990's and they have been confirmed by the data of the Fermi satellite. T…
MAGIC observations and multifrequency properties of the Flat Spectrum Radio Quasar 3C 279 in 2011
J. Aleksić, S. Ansoldi, L. A. Antonelli +168
We study the multifrequency emission and spectral properties of the quasar 3C 279. We observed 3C 279 in very high energy (VHE, E>100GeV) gamma rays, with the MAGIC telescopes duri…
Contemporaneous observations of the radio galaxy NGC 1275 from radio to very high energy gamma-rays
MAGIC Collaboration, J. Aleksić, S. Ansoldi +157
The radio galaxy NGC 1275, recently identified as a very high energy (VHE, >100 GeV) gamma-ray emitter by MAGIC, is one of the few non-blazar AGN detected in the VHE regime. In ord…
CTA contributions to the 33rd International Cosmic Ray Conference (ICRC2013)
The CTA Consortium, :, O. Abril +1102
Compilation of CTA contributions to the proceedings of the 33rd International Cosmic Ray Conference (ICRC2013), which took place in 2-9 July, 2013, in Rio de Janeiro, Brazil
Exploring high-energy processes in binary systems with the Cherenkov Telescope Array
J. M. Paredes, W. Bednarek, P. Bordas +20
Several types of binary systems have been detected up to now at high and very high gamma-ray energies, including microquasars, young pulsars around massive stars and colliding wind…
Gamma-rays from millisecond pulsar population within the central stellar cluster in the Galactic Center
W. Bednarek, T. Sobczak
It was proposed that the central dense stellar cluster in the Galactic Center, containing the mass of 4 times larger than that of the central black hole, had been formed as a…
Rapid and multi-band variability of the TeV-bright active nucleus of the galaxy IC 310
The MAGIC Collaboration, J. Aleksić, L. A. Antonelli +161
Context. The radio galaxy IC 310 has recently been identified as a gamma-ray emitter based on observations at GeV energies with Fermi-LAT and at very high energies (VHE, E>100GeV)…
Numerical modelling of gamma-ray emission produced by electrons originating from the magnetospheres of millisecond pulsars in globular clusters
A. Zajczyk, W. Bednarek, B. Rudak
Globular clusters are source of gamma-ray radiation. At GeV energies, their emission is attributed to magnetospheric activity of millisecond pulsars residing in the clusters. Inver…
Discovery of very high energy gamma-ray emission from the blazar 1ES 1727+502 with the MAGIC Telescopes
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +155
Motivated by the Costamante & Ghisellini (2002) predictions we investigated if the blazar 1ES 1727+502 (z=0.055) is emitting very high energy (VHE, E>100 GeV) gamma rays. We observ…
Influence of the Geomagnetic Field on the IACT detection technique for possible sites of CTA observatories
M. Szanecki, K. Bernlöhr, D. Sobczyńska +3
We investigate the influence of the geomagnetic field (GF) on the Imaging Air Cherenkov Telescope technique for two northern (Tenerife and San Pedro Martir) and three southern (Sal…
Gamma-rays from nebulae around binary systems containing energetic rotation powered pulsars
W. Bednarek, J. Sitarek
We consider nebulae which are created around binary systems containing rotation powered pulsars and companion stars with strong stellar winds. It is proposed that the stellar and p…
