On the cool gaseous haloes of quasars
E. P. Farina, R. Falomo, R. Decarli +2
We present optical spectroscopy of projected QSO pairs to investigate the MgII and the CIV absorption features imprinted on the spectrum of the background object by the gaseous hal…
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…
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 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…
