Tidal disruption event Calorimetry: Observational constraints on the physics of TDE optical flares
Andrew Mummery, Brian Metzger, Sjoert van Velzen +1
Tidal disruption events are routinely discovered as bright optical/UV flares, the properties of which are now well categorized on the population level. The underlying physical proc…
The relativistic tidal tensor: general solutions for stationary axisymmetric spacetimes and the Hills mass of naked singularities
Wenkang Xin, Andrew Mummery
The tidal forces experienced on an orbit contain, in principle, information about the underlying spacetime an object is moving through. Astronomical observations often probe the pr…
Compact Accretion Disks in the Aftermath of Tidal Disruption Events: Parameter Inference from Joint X-ray Spectra and UV/Optical Photometry Fitting
M. Guolo, A. Mummery, S. van Velzen +8
We present a multi-wavelength analysis of 14 tidal disruption events (TDEs)-including an off-nuclear event associated with an ultra-compact dwarf galaxy-selected for having availab…
AT 2018cow at ~5 years: additional evidence for a tidal disruption origin
Anne Inkenhaag, Andrew J. Levan, Andrew Mummery +1
The Luminous Fast Blue Optical Transient (LFBOT) AT 2018cow is the prototype of its class with an extensive set of multi-wavelength observations. Despite a rich data set there is,…
Rapid onset of a Comptonisation zone in the repeating tidal disruption event XMMSL2 J140446.9-251135
R. D. Saxton, T. Wevers, S. van Velzen +11
We report here on observations of a tidal disruption event, XMMSL2 J1404-2511, discovered in an XMM-Newton slew, in a quiescent galaxy at z=0.043. X-ray monitoring covered the epoc…
Luminous Fast Blue Optical Transients as very massive star core-collapse events
A. A. Chrimes, P. G. Jonker, A. J. Levan +1
Luminous Fast Blue Optical Transients (LFBOTs) are rare extragalactic events of unknown origin. Tidal disruptions of white dwarfs by intermediate mass black holes (BHs), mergers of…
Evidence for a steeper SMBH-Bulge mass relationship extended to low masses using TDE host galaxies
Paige Ramsden, Matt Nicholl, Sean L. McGee +1
Tidal disruption events (TDEs) are excellent tools for probing low mass supermassive black holes (SMBHs) that may otherwise remain undetected. Here, we present an extended SMBH--Bu…
Black hole supercolliders
Andrew Mummery, Joseph Silk
We show that collisions between particles free falling from infinity and a disk of material plunging off the retrograde innermost stable circular orbit of a near-extremal Kerr blac…
The plunging region of a thin accretion disc around a Schwarzschild black hole
Jake Rule, Andrew Mummery, Steven Balbus +2
A set of analytic solutions for the plunging region thermodynamics have been developed recently under the assumption that the fluid undergoes a gravity-dominated geodesic plunge in…
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…
The X-ray variability of tidal disruption events
Andrew Mummery
When a star is torn apart by the tidal forces of a supermassive black hole (a so-called TDE) a transient accretion episode is initiated and a hot, often X-ray bright, accretion dis…
Collisions with tidal disruption event disks: implications for quasi-periodic X-ray eruptions
Andrew Mummery
A popular class of models for interpreting quasi-periodic X-ray eruptions from galactic nuclei (QPEs) invoke collisions between an object on an extreme mass ratio inspiral (EMRI) a…
Discovery of Quasi-periodic Eruptions in the Tidal Disruption Event and Extreme Coronal Line Emitter AT2022upj: implications for the QPE/TDE fraction and a connection to ECLEs
Joheen Chakraborty, Erin Kara, Riccardo Arcodia +10
Quasi-periodic eruptions (QPEs) are recurring soft X-ray transients emerging from the vicinity of supermassive black holes (SMBHs) in nearby, low-mass galaxy nuclei; about ten QPE…
A Time-Dependent Solution for GSN 069 Disk Evolution and the Nature of Long-Lived Tidal Disruption Events
M. Guolo, A. Mummery, A. Ingram +3
We present the implementation of a fully time-dependent relativistic disk model-based on the light curve fitting package FitTeD-into the X-ray spectral fitting environment, pyXspec…
Galaxy scale consequences of tidal disruption events: extended emission line regions, extreme coronal lines and infrared-to-optical light echoes
Andrew Mummery, Muryel Guolo, James Matthews +3
Stars in galactic centers are occasionally scattered so close to the central supermassive black hole that they are completely disrupted by tidal forces, initiating a transient accr…
Time-resolved Hubble Space Telescope UV observations of an X-ray quasi-periodic eruption source
Thomas Wevers, Muryel Guolo, Sean Lockwood +3
X-ray quasi-periodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multi-wavelength properties are poorly constrain…
Black hole-disc coevolution in the presence of magnetic fields: refining the Thorne limit with emission from within the plunging region
Andrew Mummery
The accretion of material onto a black hole modifies the properties of that hole owing to the capture of both matter and radiation. Adding matter to the hole through an accretion d…
The properties of GSN 069 accretion disk from a joint X-ray and UV spectral analysis: stress-testing quasi-periodic eruption models
M. Guolo, A. Mummery, T. Wevers +4
We present an analysis of Hubble Space Telescope (HST) and XMM-Newton data of the tidal disruption event (TDE) candidate and quasi-periodic eruption (QPE) source GSN 069. Using ult…
