Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations
Saurabh, Hendrik Müller, Sebastiano D. von Fellenberg +282
We investigate the presence and spatial characteristics of the jet base emission in M87* at 230 GHz, enabled by the enhanced uv coverage in the 2021 Event Horizon Telescope (EHT) o…
Shadow Formation Conditions Beyond the Kerr Black Hole Paradigm
Parth Bambhaniya, Saurabh, Elisabete M. de Gouveia Dal Pino
A compact object illuminated by background radiation produces a dark silhouette. The edge of the silhouette or shadow (alternatively, the apparent boundary or the critical curve) i…
Semi-analytic studies of accretion disk and magnetic field geometry in M87*
Saurabh, Maciek Wielgus, Arman Tursunov +2
Context: Magnetic fields play a pivotal role in dynamics of black hole accretion flows and formation of relativistic jets. Observations by the Event Horizon Telescope (EHT) provide…
Time Delay of Pulsar Signals in Astrophysical Black Hole Spacetimes
Parth Bambhaniya, Viraj Kalsariya, Saurabh +4
In this paper, we investigate the fully relativistic time delay of pulsar signals propagating in the vicinity of a rotating black hole and its potential mimickers, including a defo…
Origin of the ring ellipticity in the black hole images of M87*
Rohan Dahale, Ilje Cho, Kotaro Moriyama +273
We investigate the origin of the elliptical ring structure observed in the images of the supermassive black hole M87*, aiming to disentangle contributions from gravitational, astro…
First polarization study of the M87 jet and active galactic nuclei at submillimeter wavelengths with ALMA
Ciriaco Goddi, Douglas F. Carlos
We present full-polarization observations at mm (345 GHz) conducted with the Atacama Large Millimeter/submillimeter Array (ALMA) toward Messier 87 (M87) and seven other r…
Novel Polarimetric Analysis of Near Horizon Flaring Episodes in M87* in Millimeter Wavelength
Razieh Emami, Matthew Liska, Koushik Chatterjee +15
Recent multi-wavelength observations of M87* \citep{2024A&A...692A.140A} revealed a high-energy -ray flare without a corresponding millimeter counterpart. We present a theoretic…
