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…

Periodic morphological changes in the radio structure of the gamma-ray binary LS 5039

J. Moldón, M. Ribó, J. M. Paredes

Gamma-ray binaries allow us to study physical processes such as particle acceleration up to TeV energies and VHE gamma-ray emission and absorption with changing geometrical configu…

Nonthermal processes and neutrino emission from the black hole GRO J0422+32 in a bursting state

F. L. Vieyro, Y. Sestayo, G. E. Romero +1

GRO J0422+32 is a member of the class of low-mass X-ray binaries (LMXBs). It was discovered during an outburst in 1992. During the entire episode a persistent power-law spectral co…

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…

Search for radio pulsations in LS I +61 303

A. Cañellas, B. C. Joshi, J. M. Paredes +5

Context. LS I +61 303 is a member of the select group of gamma-ray binaries: galactic binary systems that contain a massive star and a compact object, show a changing milliarcsecon…

On the origin of LS 5039 and PSR J1825-1446

J. Moldón, M. Ribó, J. M. Paredes +5

Context. The gamma-ray binary LS 5039 and the isolated pulsar PSR J1825-1446 were proposed to have been formed in the supernova remnant (SNR) G016.8-01.1. Aims. We aim to obtain th…

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-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…
