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…
Event Horizon Telescope Pattern Speeds in the Visibility Domain
Nicholas S. Conroy, Michi Bauböck, Vedant Dhruv +6
The Event Horizon Telescope is preparing to produce time sequences of black hole images, or movies. In anticipation, we developed an autocorrelation technique to measure apparent r…
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…
Dynamical Inference from Polarized Light Curves of Sagittarius A*
Angelo Ricarte, Nicholas S. Conroy, Maciek Wielgus +3
Polarimetric light curves of Sagittarius A* (Sgr A*) sometimes exhibit loops in the Stokes and plane over time, often interpreted as orbiting hotspot motion. In this work,…
