We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1, which includes, among other instruments, MAGIC, VERITAS, Whipple 10 m, and Fermi-LAT to cover the γ-ray range from 0.1 GeV to 20 TeV; RXTE and Swift to cover wavelengths from UV tohard X-rays; and GASP-WEBT, which provides coverage of radio and optical wavelengths. Optical polarization measurements were provided for a… 
Extreme HBL behavior of Markarian 501 during 2012
Aims. We aim to characterize the multiwavelength emission from Markarian 501 (Mrk 501), quantify the energy-dependent variability, study the potential multiband correlations, and describe the
Study of the variable broadband emission of Markarian 501 during the most extreme Swift X-ray activity
Markarian 501 is a bright very-high-energy (VHE, E>100 GeV) BL Lac object. Thanks to its brightness and its proximity (z=0.034), it can be detected in the VHE even during low states, making it an

We report on variability and correlation studies using multiwavelength observations of the blazar Mrk 421 during the month of February, 2010 when an extraordinary flare reaching a level of
Long-term Multiband Study of High-redshift Blazar S5 0836+71
We analyze 10 years of Fermi gamma-ray observations of the high-redshift blazar S5 0836+71 (z = 2.172) that showed a strong flare in 2015 characterized by a several-fold increase in the gamma-ray
A flat-spectrum flare in S4 0444+63 revealed by a new implementation of multiwavelength single-dish observations
Relativistic amplification boosts the contribution of the jet base to the total emission in blazars, thus making single dish observations useful and practical to characterise their physical state,
Fractional Variability—A Tool to Study Blazar Variability
Active Galactic Nuclei emit radiation over the whole electromagnetic spectrum up to TeV energies. Blazars are one subtype with their jets pointing towards the observer. One of their typical features
First multi-wavelength campaign on the gamma-ray- loud active galaxy IC 310
Context. The extragalactic very-high-energy gamma-ray sky is rich in blazars. These are jetted active galactic nuclei that are viewed at a small angle to the line-of-sight. Only a handful of objects
The NuSTAR view on hard-TeV BL Lacs
Hard-TeV BL Lacs are a new type of blazars characterized by a hard intrinsic TeV spectrum, locating the peak of their gamma-ray emission in the spectral energy distribution (SED) above 2-10 TeV. Such
