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…
Radio-to-gamma-ray Monitoring of the Narrow-Line Seyfert 1 Galaxy PMN J0948+0022 from 2008 to 2011
L. Foschini, E. Angelakis, L. Fuhrmann +39
We present more than three years of observations at different frequencies, from radio to high-energy gamma-rays, of the Narrow-Line Seyfert 1 (NLS1) Galaxy PMN J0948+0022 (z=0.585)…
High redshift Fermi blazars observed by GROND and Swift
G. Ghisellini, M. Nardini, G. Tagliaferri +7
We observed 5 gamma-ray loud blazars at redshift greater than 2 with the X-Ray Telescope (XRT) and the UltraViolet and Optical Telescope (UVOT) onboard the Swift satellite, and the…
"Flat" broad line region and gamma-ray absorption in blazars
F. Tavecchio, G. Ghisellini
We study the impact of the geometry of the broad line region (BLR) on the expected absorption, through the γγ\rightarrow e^{\pm} process, of gamma rays produced in the relativistic…
SDSS J102623.61+254259.5: the second most distant blazar at z=5.3
T. Sbarrato, G. Ghisellini, M. Nardini +7
The radio-loud quasar SDSS J102623.61+254259.5, at a redshift z=5.3, is one of the most distant radio-loud objects. Since its radio flux exceeds 100 mJy at a few GHz, it is also on…
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…
Blue Fermi Flat Spectrum Radio Quasars
G. Ghisellini, F. Tavecchio, L. Foschini +3
Many blazars detected by the Fermi satellite, observed spectroscopically in the optical, are line-less, and have been classified as BL Lac objects. Optical-UV photometry of nearly…
Emitting electrons and source activity in Markarian 501
Nijil Mankuzhiyil, Stefano Ansoldi, Massimo Persic +3
We study the variation of the broad-band spectral energy distribution (SED) of the BL Lac object Mrk 501 as a function of source activity, from quiescent to flaring. Through chi-sq…
On the redshift of the bright BL Lac object PKS 0048-097
Marco Landoni, Renato Falomo, Aldo Treves +4
Aims: The determination of elusive redshifts of bright BL Lac objects Methods: We use the capabilities of newly available spectrograph X-Shooter at European Southern Observatory (E…
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…
Evidence for an axion-like particle from PKS 1222+216?
F. Tavecchio, M. Roncadelli, G. Galanti +1
The surprising discovery by MAGIC of an intense, rapidly varying emission in the energy range 70 - 400 GeV from the flat spectrum radio quasar PKS 1222+216 represents a challenge f…
