A rapid black hole spin or emission from the plunging region?
Andrew Mummery, Jiachen Jiang, Adam Ingram +2
Emission from within the plunging region of black hole accretion flows has recently been detected in two X-ray binary systems. There is, furthermore, a possible discrepancy between…
Fitting transients with discs (FitTeD): a public light curve and spectral fitting package based on evolving relativistic discs
Andrew Mummery, Edward Nathan, Adam Ingram +1
We present FitTeD, a public light curve and spectral fitting Python-package based on evolving relativistic discs. At its heart this package uses the solutions of the time dependent…
Proof of principle X-ray reflection mass measurement of the black hole in H1743-322
Edward Nathan, Adam Ingram, James F. Steiner +9
The black hole X-ray binary H1743-322 lies in a region of the Galaxy with high extinction, and therefore it has not been possible to make a dynamical mass measurement. In this pape…
Continuum emission from within the plunging region of black hole discs
Andrew Mummery, Adam Ingram, Shane Davis +1
The thermal continuum emission observed from accreting black holes across X-ray bands has the potential to be leveraged as a powerful probe of the mass and spin of the central blac…
Reflecting on naked singularities: iron line fitting as a probe of the cosmic censorship conjecture
Andrew Mummery, Adam Ingram
We demonstrate that the X-ray iron line fitting technique can be leveraged as a powerful probe of the cosmic censorship conjecture. We do this by extending existing emission line m…
X-ray Reflection from the Plunging Region of Black Hole Accretion Disks
Jameson Dong, Guglielmo Mastroserio, Javier A. Garcıa +3
Accretion around black holes is very often characterized by distinctive X-ray reflection features (mostly, iron inner-shell transitions), which arise due to the primary radiation b…
H-AMR: A New GPU-accelerated GRMHD Code for Exascale Computing With 3D Adaptive Mesh Refinement and Local Adaptive Time-stepping
M. T. P. Liska, K. Chatterjee, D. Issa +10
General-relativistic magnetohydrodynamic (GRMHD) simulations have revolutionized our understanding of black hole accretion. Here, we present a graphics processing unit (GPU) accele…
