97. Jets in microquasars

Andrzej Zdziarski (N. Copernicus Astronomical Center, Warsaw, Poland)

12/01/2022, 15:00

I will review our current knowledge about jets in accreting X-ray binaries. I will concentrate on three well-studied systems, namely MAXI J1820+070, Cyg X-1, and Cyg X-3. The compact objects in the first two are black holes, while it is likely but not certain in Cyg X-3. Thanks to an extensive multiwavelength campaign during the recent outburst of MAXI J1820+070, the structure of its compact...

98. Recent progress in GRB studies

Bing Zhang (University of Nevada, Las Vegas)

12/01/2022, 15:25

I will present an overview of some recent progress in the GRB field. The topics include discovery and implications of TeV emission in GRB afterglows, new events that point to special progenitor channels, as well as theoretical models that help to diagnose the jet composition and central engine of both long and short GRBs.

74. Probing particle acceleration at relativistic shocks with GRBs

Brian Reville (MPIK)

12/01/2022, 16:05

Until recently, questions on the maximum particle energy produced by GRBs was primarily int he context of UHECRs. However, the recent spate of TeV gamma-ray measurements bring the question of maximum electron energies into focus. Here I will review the current status of particle acceleration at relativistic shocks, how the theoretical predictions stand up to the recent observations, and what...
