Unique probe of dark matter in the core of M87 with the Event Horizon Telescope
Thomas Lacroix, Mansour Karami, Avery E. Broderick +2
We demonstrate the unprecedented capabilities of the Event Horizon Telescope (EHT) to image the innermost dark matter profile in the vicinity of the supermassive black hole at the…
The Linear Instability of Dilute Ultrarelativistic Pair Beams
Philip Chang, Avery E. Broderick, Christoph Pfrommer +4
The annihilation of TeV photons from extragalactic TeV sources and the extragalactic background light produces ultrarelativistic beams, which are subject to powerful plas…
Bow Ties in the Sky I: The Angular Structure of Inverse Compton Gamma-ray Halos in the Fermi Sky
Avery E. Broderick, Paul Tiede, Mohamad Shalaby +4
Extended inverse Compton halos are generally anticipated around extragalactic sources of gamma rays with energies above 100 GeV. These result from inverse Compton scattered cosmic…
Testing General Relativity with Accretion-Flow Imaging of Sgr A*
Tim Johannsen, Carlos Wang, Avery E. Broderick +4
The Event Horizon Telescope is a global very-long baseline interferometer capable of probing potential deviations from the Kerr metric, which is believed to provide the unique desc…
Modeling Seven Years of Event Horizon Telescope Observations with Radiatively Inefficient Accretion Flow Models
Avery E. Broderick, Vincent L. Fish, Michael D. Johnson +6
An initial three-station version of the Event Horizon Telescope, a millimeter-wavelength very-long baseline interferometer, has observed Sagittarius A* (Sgr A*) repeatedly from 200…
Persistent Asymmetric Structure of Sagittarius A* on Event Horizon Scales
Vincent L. Fish, Michael D. Johnson, Sheperd S. Doeleman +69
The Galactic Center black hole Sagittarius A* (Sgr A*) is a prime observing target for the Event Horizon Telescope (EHT), which can resolve the 1.3 mm emission from this source on…
