Two-temperature, Magnetically Arrested Disc simulations of the jet from the supermassive black hole in M87
Andrew Chael, Ramesh Narayan, Michael D. Johnson
We present two-temperature, radiative general relativistic magnetohydrodynamic simulations of Magnetically Arrested Discs (MAD) that launch powerful relativistic jets. The mass acc…
The role of electron heating physics in images and variability of the Galactic Centre black hole Sagittarius A*
Andrew Chael, Michael E. Rowan, Ramesh Narayan +2
The accretion flow around the Galactic Center black hole Sagittarius A* (Sgr A*) is expected to have an electron temperature that is distinct from the ion temperature, due to weak…
Probing sub-GeV Dark Matter-Baryon Scattering with Cosmological Observables
Weishuang Linda Xu, Cora Dvorkin, Andrew Chael
We derive new limits on the elastic scattering cross-section between baryons and dark matter using Cosmic Microwave Background data from the Planck satellite and measurements of th…
Interferometric Imaging Directly with Closure Phases and Closure Amplitudes
Andrew A. Chael, Michael D. Johnson, Katherine L. Bouman +3
Interferometric imaging now achieves angular resolutions as fine as 10 microarcsec, probing scales that are inaccessible to single telescopes. Traditional synthesis imaging methods…
