Polarization Observations of AGN Jets: Past and Future

Jongho Park, Juan Carlos Algaba

The magnetic field is believed to play a critical role in the bulk acceleration and propagation of jets produced in active galactic nuclei (AGN). Polarization observations of AGN j…

Implications from the velocity profile of the M87 jet: a possibility of a slowly rotating black hole magnetosphere

Motoki Kino, Masaaki Takahashi, Tomohisa Kawashima +4

Motivated by the measured velocity profile of the M87 jet using the KVN and VERA Array (KaVA) by Park et al. indicating that the starting position of the jet acceleration is farthe…

Constraints on black-hole charges with the 2017 EHT observations of M87*

Prashant Kocherlakota, Luciano Rezzolla, Heino Falcke +234

Our understanding of strong gravity near supermassive compact objects has recently improved thanks to the measurements made by the Event Horizon Telescope (EHT). We use here the M8…

The Polarized Image of a Synchrotron Emitting Ring of Gas Orbiting a Black Hole

Ramesh Narayan, Daniel C. M. Palumbo, Michael D. Johnson +237

Synchrotron radiation from hot gas near a black hole results in a polarized image. The image polarization is determined by effects including the orientation of the magnetic field i…

Polarimetric properties of Event Horizon Telescope targets from ALMA

Ciriaco Goddi, Ivan Marti-Vidal, Hugo Messias +31

We present the results from a full polarization study carried out with ALMA during the first VLBI campaign, which was conducted in Apr 2017 in the 3mm and 1.3mm bands, in con…
