23. How relativistic jets from AGNs affect the host galaxy and its environment

Relativistic jets from AGNs are an important driver of feedback in galaxies with an active black hole. They first interact with the host galaxy's ISM before breaking out to larger scales, significantly affecting the galaxy's morphology and evolution. Cosmological simulations predict that massive galaxies undergo several such episodes in the course of their evolution. However, large scale...

34. Jets, Blobs, and Circular Polarization: Using PLUTO to Model Time Domain Variability in Blazars

Extragalactic jets are highly collimated beams of relativistic plasma that emanate from the centers of Active Galactic Nuclei (AGN). Despite decades of dedicated observation and study the underlying plasma composition of these relativistic outflows remains largely unknown. The polarized emission emanating from relativistic jets, however, can now be imaged on micro arcsecond scales using Global...

78. Self-consistent modeling of particle acceleration and evolution of spectral distribution in blazars.

Blazar emission models are challenged by recent multiwavelength and multi-messenger observations. The only way to transform these observational evidences into an advance of the understanding of the physical phenomena behind, is to build models that are as much as possible reproducible, robust, and with a solidly connection to the phenomenology. I will give some examples of this approach using...

Comparable energy contents of radio lobes in FR II sources calculated
using their luminosities and their confinement by external medium seem
to exclude possibility of their energy domination by protons.
This suggests that the jets powering the lobes are pair dominated.
Large pair content of jets is indicated also by blazar models, which
for the electron-proton plasma predict much larger jet...

55. Theory vs. observations: Unraveling black hole accretion physics with the Event Horizon Telescope

Mr Michael Janssen (Radboud University)

The Event Horizon Telescope (EHT) is a global VLBI array with the capability to study millimetre wave emission from extragalactic radio sources with an unprecedented micro-arcsecond resolution. In a 2017 observing run, the EHT observed M87 and Sgr A* - the two primary EHT targets - alongside several other AGN sources. Eight telescopes participated in this observing session, including the...

25. Reconnection and Associated Flares in Global Relativistic Jets Containing Helical Magnetic Fields with PIC Simulations

Prof. Kenichi Nishikawa (Alabama A&M University)

In the study of relativistic jets one of the key open questions is their interaction with the environment on the microscopic level. Here, we study the evolution of both electron–proton and electron–positron relativistic jets containing helical magnetic fields, focusing on their interaction with an ambient plasma. We have performed simulations of “global” jets containing helical magnetic fields...
