Demographics of black holes at 100 R scales: accretion flows, jets, and shadows
Dhanya G. Nair, Neil M. Nagar, Venkatessh Ramakrishnan +87
Using the Event Horizon Telescope (EHT), the gravitationally lensed rings around the supermassive black holes (SMBHs) in Messier 87 (M87) and Sagittarius A* (Sgr A*) have now been…
The Detection of HO Maser Emission from mid-IR Red Galaxies
C. Y. Kuo, C. Y. Tai, A. Constantin +7
We report the detection of HO maser emission in 4 out of 77 (5.2%) mid-IR red galaxies that meet the color criteria of and and are classified as Type-…
First Very Long Baseline Interferometry Detections at 870μm
Alexander W. Raymond, Sheperd S. Doeleman, Keiichi Asada +276
The first very long baseline interferometry (VLBI) detections at 870m wavelength (345GHz frequency) are reported, achieving the highest diffraction-limited angular resolutio…
The Black Hole Explorer: Motivation and Vision
Michael D. Johnson, Kazunori Akiyama, Rebecca Baturin +65
We present the Black Hole Explorer (BHEX), a mission that will produce the sharpest images in the history of astronomy by extending submillimeter Very-Long-Baseline Interferometry…
The Black Hole Explorer: Operating a Hybrid Observatory
Sara Issaoun, Kim Alonso, Kazunori Akiyama +16
We present a baseline science operations plan for the Black Hole Explorer (BHEX), a space mission concept aiming to confirm the existence of the predicted sharp ``photon ring" resu…
Accessing a New Population of Supermassive Black Holes with Extensions to the Event Horizon Telescope
Xinyue Alice Zhang, Angelo Ricarte, Dominic W. Pesce +6
The Event Horizon Telescope has produced resolved images of the supermassive black holes Sgr A* and M87*, which present the largest shadows on the sky. In the next decade, technolo…
