Relativistic jets of blazars
T Hovatta, E Lindfors - New Astronomy Reviews, 2019 - Elsevier
Relativistic jets of active galactic nuclei have been known to exist for 100 years. Blazars with
their jet pointing close to our line of sight are some of the most variable and extreme objects …

Polarized blazar X-rays imply particle acceleration in shocks
Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point
nearly along the line of sight, is produced by high-energy particles, up to around 1 TeV …

The origin of the extragalactic gamma-ray background and implications for dark matter annihilation
The origin of the extragalactic γ-ray background (EGB) has been debated for some time. The
EGB comprises the γ-ray emission from resolved and unresolved extragalactic sources …

The extragalactic background light, the Hubble constant, and anomalies: conclusions from 20 years of TeV gamma-ray observations
J Biteau, DA Williams - The Astrophysical Journal, 2015 - iopscience.iop.org
Ground-based observatories have been collecting 0.2–20 TeV gamma-rays from blazars for
about twenty years. These gamma-rays can experience absorption along the line of sight …

Direct detection constraints on blazar-boosted dark matter
JW Wang, A Granelli, P Ullio - Physical Review Letters, 2022 - APS
We explore the possibility that relativistic protons in the extremely powerful jets of blazars
may boost via elastic collisions the dark matter particles in the surroundings of the source to …
