    Testing the evolution of the DB white dwarf GD 358: first results of a new approach using asteroseismology
    Aims: We present a new method that investigates the evolutionary history of the pulsating DB white dwarf GD 358 using asteroseismology. This is done considering...

    Testing two-component models on very high-energy gamma-ray-emitting BL Lac objects
    Context. It has become evident that one-zone synchrotron self-Compton models are not always adequate for very high-energy (VHE) gamma-ray-emitting blazars...

    TeV pion bumps in the gamma-ray spectra of flaring blazars
    Context. Very high-energy (VHE, E > 100 GeV) observations of the blazar Mrk 501 with MAGIC in 2014 provided evidence for an unusual narrow spectral feature at...

    The 2009 multiwavelength campaign on Mrk 421: Variability and correlation studies
    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...
