Particle acceleration at recollimation shocks in sub-relativistic jets. A model for jets in Seyfert Galaxies, Microquasars and Protostellar Systems

Enrico Peretti, Elena Amato, Silvio Sergio Cerri +3

Growing observational evidence suggests that subrelativistic (SR) astrophysical jets may accelerate particles at slowly evolving standing shocks. Recollimation shocks (RCS) are exp…

The environment of TeV halo progenitors

Lioni-Moana Bourguinat, Carmelo Evoli, Pierrick Martin +1

TeV haloes are extended sources of very-high-energy gamma rays found around some middle-aged pulsars. The emission spanning several tens of parsecs suggests an efficient confinemen…

Extended TeV Halos May Commonly Exist around Middle-Aged Pulsars

A. Albert, R. Alfaro, C. Alvarez +81

Extended gamma-ray emission around isolated pulsars at TeV energies, also known as TeV halos, have been found around a handful of middle-aged pulsars. The halos are significantly m…

Testing the Molecular Cloud Paradigm for Ultra-High-Energy Gamma Ray Emission from the Direction of SNR G106.3+2.7

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +87

Supernova remnants (SNRs) are believed to be capable of accelerating cosmic rays (CRs) to PeV energies. SNR G106.3+2.7 is a prime PeVatron candidate. It is formed by a head region,…

Time-resolved hadronic particle acceleration in the recurrent Nova RS Ophiuchi

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +171

Recurrent Novae are repeating thermonuclear explosions in the outer layers of white dwarfs, due to the accretion of fresh material from a binary companion. The shock generated by e…

Revealing x-ray and gamma ray temporal and spectral similarities in the GRB 190829A afterglow

H. E. S. S. Collaboration

Gamma-ray bursts (GRBs), which are bright flashes of gamma rays from extragalactic sources followed by fading afterglow emission, are associated with stellar core collapse events.…
