Supermassive Black Holes: modelling strongly and weakly magnetised misaligned accretion disks
Joshua Samuel Stanway, Cora Prather, Derek Ward-Thompson +3
In this paper, we carry out a numerical study of misaligned accretion disks around spinning supermassive black holes. Here, we conduct a parameter survey covering a range of initia…
Observational Properties of Near-Maximally Spinning Supermassive Black Holes
Tegan A. Thomas, Angelo Ricarte, Cora Prather +1
Black holes described by the Kerr metric can have a theoretical maximum dimensionless spin parameter of , but several effects may limit the maximum spin parameter in…
Variability in Black Hole Accretion: Dependence on Rotational and Magnetic Energy Balance
Hyerin Cho, Ramesh Narayan
Most general relativistic magnetohydrodynamic simulations of black hole (BH) hot accretion flows are initialized with small rotating tori and produce stable jets with only small fl…
Multi-Zone Modeling of Black Hole Accretion and Feedback in 3D GRMHD: Bridging Vast Spatial and Temporal Scales
Hyerin Cho, Ben S. Prather, Kung-Yi Su +2
Simulating accretion and feedback from the horizon scale of supermassive black holes (SMBHs) out to galactic scales is challenging because of the vast range of scales involved. Ela…
Bridging Scales in Black Hole Accretion and Feedback: Magnetized Bondi Accretion in 3D GRMHD
Hyerin Cho, Ben S. Prather, Ramesh Narayan +4
Fueling and feedback couple supermassive black holes (SMBHs) to their host galaxies across many orders of magnitude in spatial and temporal scales, making this problem notoriously…
Calculation and Uncertainty of Fast Radio Burst Structure Based on Smoothed Data
Adrian T. Sutinjo, Danica R. Scott, Clancy W. James +7
Studies of the time-domain structure of fast radio bursts (FRBs) require an accurate estimate of the FRB dispersion measure in order to recover the intrinsic burst shape. Furthermo…
CELEBI: The CRAFT Effortless Localisation and Enhanced Burst Inspection Pipeline
D. R. Scott, H. Cho, C. K. Day +8
Fast radio bursts (FRBs) are being detected with increasing regularity. However, their spontaneous and often once-off nature makes high-precision burst position and frequency-time…
Analytical Model of Disk Evaporation and State Transitions in Accreting Black Holes
Hyerin Cho, Ramesh Narayan
State transitions in black hole X-ray binaries are likely caused by gas evaporation from a thin accretion disk into a hot corona. We present a height-integrated version of this pro…
Limits on precursor and afterglow radio emission from a fast radio burst in a star-forming galaxy
Shivani Bhandari, Keith W. Bannister, Emil Lenc +17
We present a new fast radio burst (FRB) at 920 MHz discovered during commensal observations conducted with the Australian Square Kilometre Array Pathfinder (ASKAP) as part of the C…
Spectropolarimetric analysis of FRB 181112 at microsecond resolution: Implications for Fast Radio Burst emission mechanism
Hyerin Cho, Jean-Pierre Macquart, Ryan M. Shannon +14
We have developed a new coherent dedispersion mode to study the emission of Fast Radio Bursts that trigger the voltage capture capability of the Australian SKA Pathfinder (ASKAP) i…
First Constraints on Compact Dark Matter from Fast Radio Burst Microstructure
Mawson W. Sammons, Jean-Pierre Macquart, Ron D. Ekers +5
Despite existing constraints, it remains possible that up to of all dark matter is comprised of compact objects, such as the black holes in the 10-100\,M range whose…
The low density and magnetization of a massive galaxy halo exposed by a fast radio burst
J. Xavier Prochaska, Jean-Pierre Macquart, Matthew McQuinn +16
Present-day galaxies are surrounded by cool and enriched halo gas extending to hundreds of kiloparsecs. This halo gas is thought to be the dominant reservoir of material available…
