Abstract:
1RXS J101015.9-311909 is a galaxy located at a redshift of z=0.14
hosting an active nucleus (called AGN) belonging to the class of
bright BL Lac objects. Observations at high (HE, E>100MeV) and very
high (VHE, E>100GeV) energies provide insights into the origin of
very energetic particles present in such sources and the radiation
processes at work. We report on results from VHE observations
performed between 2006 and 2010 with the H.E.S.S. instrument, an array
of four imaging atmospheric Cherenkov telescopes. H.E.S.S. data have
been analysed with enhanced analysis methods, making the detection of
faint sources more significant.
Description:
The tables represent the spectra and the light curves shown in the
paper. We include the HESS and Fermi spectral points, and the HESS,
Fermi/LAT and ATOM light curves.
