TL;DR: In this paper, the authors conducted a multifrequency campaign for the TeV blazar Markarian 421 in 1998 April, and the campaign started from a pronounced high-amplitude flare recorded by BeppoSAX and Whipple; the ASCA observation started 3 days later.

TL;DR: In this article, the authors used 73 h of stereoscopic data taken with the MAGIC telescopes to investigate the very high energy (VHE) gamma-ray emission of the Crab pulsar, and they provided the widest spectra to date of the VHE components of both peaks, and these spectra extend to the energy range of satellite-borne observatories.

TL;DR: In this article, the authors present temporal and spectral analysis to study the X-ray variability trends for a blazar, and they find that the values of soft lags, i.e., delays of soft photons with respect to hard photons, differ from flare to flare, ranging from a few hundred seconds to about 1 hr.

TL;DR: In this paper, the authors presented the results of a thorough temporal and spectral analysis of all the data available to us, focusing in particular on the flare of April 1998, which was simultaneously observed also at TeV energies.

TL;DR: In this article, the authors reported the detection of very high energy (VHE, E > 100 GeV) -ray emission from NGC 1275, the central radio galaxy of the Perseus cluster of galaxies.
