126. TeV-PeV gamma-ray emissions from Galactic Stellar-mass Black Holes

Shigero KIMURA

Galactic stellar-mass black holes, both isolated black holes and black holes in binaries, are proposed as Galactic PeVatron candidates. Recent discovery of TeV-PeV gamma-rays from micro-quasars by LHAASO strengthens the scenarios of micro-quasars as PeVatrons, but the origin of gamma-ray emissions are unknown. LHAASO also discovered mysterious “dark” sources that do not exhibit counterparts in...

127. PeV particles and multi-messenger radiation from super-Eddington accreting Galactic compact objects

Enrico PERETTI

Extreme accretion goes hand to hand with strong winds and outflows.
In particular, winds are observed to reach mildly relativistic velocities and develop bubble structures in
super-Eddington accreting stellar mass compact objects powering Ultra-Luminous X-ray Sources (ULXs).
I will present a model for particle acceleration and associated multi-messenger emission in the bubbles powered by...

130. New Galactic Magnetic Field model and cosmic ray propagation

Dmitri Semikoz (APC, Paris)

We constructed new model of large scale Galactic Magnetic Field. We have achieved several important improvements compared to previous approaches. Due to account of our location inside of the Local Bubble our model does not require introduction of striated fields. For the first time we showed that the Fan Region in outer Galaxy can be modelled as a Galactic-scale feature. We identify the GMF...

155. Interpretation for Gamma-Ray Afterglows in GRB 221009A and GRB 240529A

"We present simulation results for the multiwavelength afterglow lightcurves in GRB 221009A and GRB 240529A
based our time-dependent numerical codes.
The famous BOAT GRB, GRB 221009A, has been interpreted by a very narrow jet and an additional jet component.
The required opening angle to reproduce the very early break in the TeV lightcurve is extremely small.
Here, we present an...
