Investigating the Lorentz Invariance Violation effect using different cosmological backgrounds
Hassan Abdalla, Garret Cotter, Michael Backes +2
Familiar concepts in physics, such as Lorentz symmetry, are expected to be broken at energies approaching the Planck energy scale as predicted by several quantum-gravity theories.…
Revisiting the TeV flare of PKS 2155-304 in 2006
Hong-Bin Tan, Ruo-Yu Liu, Markus Böttcher
Blazars, a subclass of active galactic nuclei (AGN), are known to be bright -ray sources, frequently exhibiting active (flaring) periods. The blazar PKS~2155-304 is a high synch…
Discovery of a Radiation Component from the Vela Pulsar Reaching 20 Teraelectronvolts
The H. E. S. S. Collaboration, :, F. Aharonian +178
Gamma-ray observations have established energetic isolated pulsars as outstanding particle accelerators and antimatter factories in the Galaxy. There is, however, no consensus rega…
A multi-zone view on the multi-wavelength emission of blazars
Ruo-Yu Liu, Rui Xue, Ze-Rui Wang +2
In this work, a time-dependent modeling is developed to study the emission properties of blazars in the low state. Motivated by various observations, we speculate and assume that n…
Target of Opportunity observations of flaring blazars with H.E.S.S.
M. Cerruti, C. Boisson, M. Böttcher +8
Blazars are the most common class of TeV extragalactic emitters. In the framework of the AGN unified model, they are understood as AGNs with a relativistic jet pointing close the l…
Multiwavelength Observations of the Blazar PKS~0735+178 in Spatial and Temporal Coincidence with an Astrophysical Neutrino Candidate IceCube-211208A
M. Pohl, K. Mori
We report on multiwavelength target-of-opportunity observations of the blazar PKS 0735+178, located 2.2 degrees away from the best-fit position of the IceCube neutrino event 211208…
