Detailed high-energy characteristics of AXP 4U 0142+61: Multi-year observations with INTEGRAL, RXTE, XMM-Newton, and ASCA [PDF]

open access: yes, 2008
4U 0142+61 is one of the Anomalous X-ray Pulsars exhibiting hard X-ray emission above 10 keV discovered with INTEGRAL. In this paper we present detailed spectral and temporal characteristics both in the hard X-ray (> 10 keV) and soft X-ray (

Multi-wavelength study of OT 081: broadband modelling of a transitional blazar [PDF]

open access: yes
OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $E>$100\,GeV) $\gamma$-ray data taken by the MAGIC and H.E.S.S.

Searches for dark matter annihilation signatures in the Segue 1 satellite galaxy with the MAGIC-I telescope [PDF]

open access: yes, 2011
We report the results of the observation of the nearly satellite galaxy Segue 1 performed by the MAGIC-I ground-based gamma-ray telescope between November 2008 and March 2009 for a total of 43.2 hours.

A compact X-ray emitting binary in likely association with 4FGL J0935.3+0901 [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
4FGL J0935.3+0901 is a γ-ray source detected by the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope. We have conducted detailed analysis of the LAT data for this source and multiwavelength studies of the source field.

Detection of very high energy gamma-ray emission from NGC 1275 by the MAGIC telescopes [PDF]

open access: yes, 2011
We report on the detection of very-high energy (VHE, E > 100 GeV) -ray emission from NGC 1275, the central radio galaxy of the Perseus cluster of galaxies.

Morphological and spectral properties of the W51 region measured with the MAGIC telescopes [PDF]

open access: yes, 2012
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 CXO J192318.5+140305 was found likely associated with the supernova remnant.

Hard TeV spectra of blazars and the constraints to the infrared intergalactic background [PDF]

open access: yes, 2006
Recent gamma-ray observations of the blazar 1ES 1101−232 (redshift z = 0.186) reveal that the unabsorbed TeV spectrum is hard, with spectral index α 0.5 [F(ν) ∝ ν −α ].

Teraelectronvolt pulsed emission from the Crab pulsar detected by MAGIC [PDF]

open access: yes, 2015
Aims. We investigate the extension of the very high-energy spectral tail of the Crab Pulsar at energies above 400 GeV. Methods. We analyzed ~320 h of good-quality Crab data obtained with the MAGIC telescope from February 2007 to April 2014. Results. We
