Thermal and non-thermal emission from supermassive black hole circumbinary disks: Disks, Coronae, Streams, and Cavities
Chris Nagele, Julian H. Krolik, Brooks E. Kinch +4
The search for electromagnetic signals from supermassive black hole (SMBH) binary systems is one of the cornerstones of multi-messenger astrophysics, complementing gravitational wa…
Simulation-Based Prediction of Black Hole Fe K Line Profiles
Chris Nagele, Julian H. Krolik, Brooks E. Kinch +1
One of the most useful spectral diagnostics of accreting black hole systems is the Fe K fluorescence line. Detected in many systems, it is often used to estimate the black hole…
Pulsational mass loss from supermassive stars creates the compact shells of Little Red Dots
Devesh Nandal, Igor Chilingarian, Chris Nagele +3
Little Red Dots (LRDs) have emerged as one of the central puzzles of the JWST era. Their spectra increasingly require dense gas close to the source, yet the physical origin of that…
Simulation-Based Prediction of Black Hole Spectra: From to
Chris Nagele, Julian H. Krolik, Rongrong Liu +2
It has long been thought that black hole accretion flows are driven by magnetohydrodynamic (MHD) turbulence, and there are now many general relativistic global simulations illustra…
Ignition of weak interactions and r-process outflows in super-collapsar accretion disks
Aman Agarwal, Daniel M. Siegel, Brian D. Metzger +1
The collapse of rotating massive (~) stars resulting in hyperaccreting black holes (BHs; "collapsars") is a leading model for the central engines of long-duration gamma…
Simulation-Based Prediction of Black Hole X-ray Spectra and Spectral Variability
Rongrong Liu, Chris Nagele, Julian H Krolik +2
Data derived from general relativistic magnetohydrodynamic simulations of accretion onto black holes can be used as input to a postprocessing scheme that predicts the radiated spec…
