Abstract:
The observation of gamma-ray flares from blazar 0836+710 in 2011,
following a period of quiescence, offered an opportunity to study
correlated activity at different wavelengths for a high-redshift
(z=2.218) active galactic nucleus.
Optical and radio monitoring, plus Fermi-LAT gamma-ray monitoring
provided 2008-2012 coverage, while Swift offered auxiliary optical,
ultraviolet, and X-ray information. Other contemporaneous observations
were used to construct a broad-band spectral energy distribution.
Description:
The Fermi-LAT data (100MeV-300GeV) considered for this analysis cover
the period from 2008 August 4 (MJD 54682) to 2012 January 31 (MJD
55957).
