Estimados, 

El próximo lunes 28 de junio a las 11:00 h, el Dr. Omer Bromberg, de la
Universidad de Tel Aviv, dará una charla sobre jets relativistas
altamente magnetizados. Abajo pueden encontrar los datos para conectarse
al coloquio. 

Saludos cordiales, 

Florencia

Title: Energy dissipation channels in highly magnetized relativistic
jets 

Abstract: 

It is well established that most astrophysical relativistic jets are
powered electromagnetically by the rotational energy of a central
compact object, likely an accreting black-hole (BH). However, how this
energy is mediated to particles and transferred to the observed
radiation is a subject of active debates. AGN jets show evidence for
efficient energy dissipation over a large range of length scales.
Putative emission is observed coming from the vicinity of the BH at
distances of a few gravitational radii, as seen in the M87 jet by the
event horizon telescope collaboration, whereas the same jets can emit
energy at distances 6-7 orders of magnitude larger. This calls for more
than one dissipation process to come into play. In this talk I will
review several possible energy dissipation channels operating at
different scales from the BH. I will discuss the required conditions for
each process to work, the physical model and observational consequences.
I will also discuss plans for future studies.
