Magnetic fields in galaxies are produced via the amplification of seed magnetic fields of
unknown nature. The seed fields, which might exist in their initial form in the intergalactic …

The second catalog of active galactic nuclei (AGNs) detected by the Fermi Large Area
Telescope (LAT) in two years of scientific operation is presented. The second LAT AGN …

This catalog summarizes 117 high-confidence⩾ 0. 1 GeV gamma-ray pulsar detections
using three years of data acquired by the Large Area Telescope (LAT) on the Fermi satellite …

We present the first catalog of active galactic nuclei (AGNs) detected by the Large Area
Telescope (LAT), corresponding to 11 months of data collected in scientific operation mode …

This paper presents light curves as well as the first systematic characterization of variability
of the 106 objects in the high-confidence Fermi Large Area Telescope Bright AGN Sample …

We present a catalog of high-energy gamma-ray sources detected by the Large Area
Telescope (LAT), the primary science instrument on the Fermi Gamma-ray Space Telescope …

Very high energy (VHE) γ-ray emission from the flat spectrum radio quasar (FSRQ) PKS
1222+ 21 (4C 21.35, z= 0.432) was detected with the MAGIC Cherenkov telescopes during …

Recent claims that the strength B IGMF of the intergalactic magnetic field (IGMF) is≳ 10− 15
G are based on upper limits to the expected cascade flux in the GeV band produced by …

We consider constraints on primordial black holes (PBHs) in the mass range if the dark
matter (DM) comprises weakly interacting massive particles (WIMPs) that form haloes …

ABSTRACT BL Lac objects are the best candidates to study the jet properties since their
spectral energy distributions (SEDs) are less contaminated by the emission from the …
