Colloquium on May. 23rd, 2019

Polarization of relativistic electrons in both ordered & large-scale and random & small-scale magnetic field


Speaker: Jirong Mao (YNAO)

Venue: Room 2317, SWIFAR Building

Time: 2:00 PM, Tuesday, 23rd May, 2019

Abstract:

Polarization radiation is common in high-energy astrophysical field. In this talk, we will first discuss synchrotron polarization in the case that we consider the effects from both thermal and nonthermal electrons. In this case, we show some diversities of synchrotron polarization.

We also discuss the polarization of the electron radiation in random and small-scale magnetic field. The properties are different from those of synchrotron polarization.

In order to compare optical and radio observations, we perform radiative transfer in both cases. We will also illustrate the general application to some kinds of interesting objects in high-energy astrophysical field.
