Spectral Energy Distribution of Markarian 501: Quiescent State vs. Extreme Outburst
The VERITAS Collaboration, V. A. Acciari, T. Arlen +225
The very high energy (VHE; E > 100 GeV) blazar Markarian 501 has a well-studied history of extreme spectral variability and is an excellent laboratory for studying the physical pro…
Radiation from matter entrainment in astrophysical jets: the AGN case
Anabella T. Araudo, Valenti Bosch-Ramon, Gustavo E. Romero
Jets are found in a variety of astrophysical sources, from young stellar objects to active galactic nuclei. In all the cases the jet propagates with a supersonic velocity through t…
Insights Into the High-Energy Gamma-ray Emission of Markarian 501 from Extensive Multifrequency Observations in the Fermi Era
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +6
We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average LAT gamma-ray spectrum of Mrk 501 can be well descr…
Gamma-rays from SS~433 and its interaction with the W50 nebula
Pol Bordas, Valentí Bosch-Ramon, Josep Maria Paredes
We investigate the production of gamma-rays in the inner regions of SS 433 and in its interaction between its jets and the W50 nebula. We estimate the VHE emission that can be gene…
The evolution of the large-scale emission in FRI jets
Pol Bordas, Valentí Bosch-Ramon, Manel Perucho
Recent observations in X-rays and gamma-rays of nearby FRI radio galaxies have raised the question of the origin of the emission detected in the termination structures of their jet…
On the origin of correlated X-ray/VHE emission from LS I +61 303
V. Zabalza, J. M. Paredes, V. Bosch-Ramon
The MAGIC collaboration has recently reported correlated X-ray and very high-energy gamma-ray emission from the gamma-ray binary LS I +61 303 during ~60% of one orbit. These observ…
