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…
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…
JWST Observations of SN 2024ggi I: Interpretation and Model Comparison of the Type II Supernova 2024ggi at 55 days Past Explosion
E. Baron, C. Ashall, J. M. DerKacy +40
We present panchromatic 0.4-21 microns observations of the nearby (about 7.2 Mpc) Type II supernova 2024ggi, obtained during the plateau phase at about 55 d past explosion. Our dat…
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…
JWST's First View of Tidal Disruption Events: Compact, Accretion-Driven Emission Lines & Strong Silicate Emission in an Infrared-selected Sample
Megan Masterson, Kishalay De, Christos Panagiotou +7
Mid-infrared (MIR) emission from tidal disruption events (TDEs) is a powerful probe of the circumnuclear environment around dormant supermassive black holes. This emission arises f…
Discovery of a likely Type II SN at =3.6 with JWST
D. A. Coulter, J. D. R. Pierel, C. DeCoursey +30
Transient astronomy in the early, high-redshift (z > 3) Universe is an unexplored regime that offers the possibility of probing the first stars and the Epoch of Reionization. Durin…
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…
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…
