Horizon-scale variability of M87* from 2017--2021 EHT observations
The Event Horizon Telescope Collaboration
We report three epochs of polarized images of M87* at 230\,GHz using data from the Event Horizon Telescope (EHT) taken in 2017, 2018, and 2021. The baseline coverage of the 2021 ob…
Selective Dynamical Imaging of Interferometric Data
Joseph Farah, Peter Galison, Kazunori Akiyama +16
Recent developments in very long baseline interferometry (VLBI) have made it possible for the Event Horizon Telescope (EHT) to resolve the innermost accretion flows of the largest…
First Sagittarius A* Event Horizon Telescope Results. II. EHT and Multi-wavelength Observations, Data Processing, and Calibration
The Event Horizon Telescope Collaboration
We present Event Horizon Telescope (EHT) 1.3 mm measurements of the radio source located at the position of the supermassive black hole Sagittarius A* (Sgr A*), collected during th…
Relativistic AGN jets III. Synthesis of synchrotron emission from Double-Double Radio Galaxies
S. Walg, A. Achterberg, S. Markoff +2
The class of Double-Double Radio Galaxies (DDRGs) relates to episodic jet outbursts. How various regions and components add to the total intensity in radio images is less well know…
Flares in the Galactic center I: orbiting flux tubes in Magnetically Arrested Black Hole Accretion Disks
O. Porth, Y. Mizuno, Z. Younsi +1
Recent observations of SgrA* by the GRAVITY instrument have astrometrically tracked infrared flares (IR) at distances of gravitational radii (). In this paper, we st…
Deep Horizon; a machine learning network that recovers accreting black hole parameters
Jeffrey van der Gucht, Jordy Davelaar, Luc Hendriks +5
The Event Horizon Telescope recently observed the first shadow of a black hole. Images like this can potentially be used to test or constrain theories of gravity and deepen the und…
First M87 Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole
The Event Horizon Telescope Collaboration
When surrounded by a transparent emission region, black holes are expected to reveal a dark shadow caused by gravitational light bending and photon capture at the event horizon. To…
Causality and stability of cosmic jets
O. Porth, S. S. Komissarov
In stark contrast to their laboratory and terrestrial counterparts, the cosmic jets appear to be very stable. We propose that the reason behind this remarkable property is the loss…
