Unprecedented study of the broadband emission of Mrk 421 during flaring activity in March 2010
(EDP Sciences, 2015-05-27)
Context. Because of its proximity, Mrk 421 is one of the best sources on which to study the nature of BL Lac objects. Its proximity allows us to characterize its broadband spectral energy distribution (SED). Aims. The ...
FirstNuSTAR observations of MRK 501 within a radio to TeV multi-instrument campaign
(IOP Publishing, 2015-10-10)
We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 2013 April 1 and August 10, including the first detailed characterization of the synchrotron peak with Swift and NuSTAR. During ...
The 2009 multiwavelength campaign on Mrk 421: variability and correlation studies
(EDP Sciences, 2015-04-17)
Aims. We perform an extensive characterization of the broadband emission of Mrk 421, as well as its temporal evolution, during the non-flaring (low) state. The high brightness and nearby location (z = 0.031) of Mrk 421 ...
Multiwavelength observations of Mrk 501 in 2008
(EDP Sciences, 2015-12-17)
Context. Blazars are variable sources on various timescales over a broad energy range spanning from radio to very high energy (>100 GeV, hereafter VHE). Mrk 501 is one of the brightest blazars at TeV energies and has been ...
