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…
Power of simultaneous X-ray and UV high-resolution spectroscopy for probing AGN outflows
Missagh Mehdipour, Laura W. Brenneman, Jon M. Miller +6
Black hole accretion in active galactic nuclei (AGN) is coupled to the evolution of their host galaxies. Outflowing winds in AGN can play an important role in this evolution throug…
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…
Multistructured accretion flow of Sgr A* II: Signatures of a Cool Accretion Disk in Hydrodynamic Simulations of Stellar Winds
Mayura Balakrishnan, Christopher M. P. Russell, Lia Corrales +8
Hydrodynamic simulations of the stellar winds from Wolf-Rayet stars within the Galactic Center can provide predictions for the X-ray spectrum of supermassive black hole Sgr A*. Her…
Multistructured accretion flow of Sgr A* I: Examination of a RIAF model
Mayura Balakrishnan, Lia Corrales, Sera Markoff +8
The extreme low-luminosity supermassive black hole Sgr A* provides a unique laboratory in which to test radiatively inefficient accretion flow (RIAF) models. Previous fits to the q…
Chandra Study of the Proper Motion of HST-1 in the Jet of M87
Rameshan Thimmappa, Joey Neilsen, Daryl Haggard +2
The radio galaxy M87 is well known for its jet, which features a series of bright knots observable from radio to X-ray wavelengths. We analyze the X-ray image and flux variability…
Broadband Multi-wavelength Properties of M87 during the 2018 EHT Campaign including a Very High Energy Flaring Episode
J. C. Algaba, M. Balokovic, S. Chandra +738
The nearby elliptical galaxy M87 contains one of the only two supermassive black holes whose emission surrounding the event horizon has been imaged by the Event Horizon Telescope (…
Ordered magnetic fields around the 3C 84 central black hole
G. F. Paraschos, J. -Y. Kim, M. Wielgus +279
3C84 is a nearby radio source with a complex total intensity structure, showing linear polarisation and spectral patterns. A detailed investigation of the central engine region nec…
