Descripción
Context. We present the discovery of very high energy (VHE, E > 100
GeV) γ-ray emission from the BL Lac object 1ES 1215+303 by the
MAGIC telescopes and simultaneous multi-wavelength data in a broad
energy range from radio to γ-rays. Aims: We study the VHE
γ-ray emission from 1ES 1215+303 and its relation to the emissions
in other wavelengths. Methods: Triggered by an optical outburst,
MAGIC observed the source in 2011 January - February for 20.3 h. The
target was monitored in the optical R-band by the KVA telescope that
also performed optical polarization measurements. We triggered target of
opportunity observations with the Swift satellite and obtained
simultaneous and quasi-simultaneous data from the Fermi Large Area
Telescope and from the Metsähovi radio telescope. We also present
the analysis of older MAGIC data taken in 2010. Results: The
MAGIC observations of 1ES 1215+303 carried out in 2011 January -
February resulted in the first detection of the source at VHE with a
statistical significance of 9.4σ. Simultaneously, the source was
observed in a high optical and X-ray state. In 2010 the source was
observed in a lower state in optical, X-ray, and VHE, while the GeV
γ-ray flux and the radio flux were comparable in 2010 and 2011.
The spectral energy distribution obtained with the 2011 data can be
modeled with a simple one zone SSC model, but it requires extreme values
for the Doppler factor or the electron energy distribution.
