Tidal disruption event rates across cosmic time: forecasts for LSST, Roman, and JWST and their constraints on the supermassive black hole mass function
Mitchell Karmen, Suvi Gezari, Colin Norman +1
Measuring the mass distribution of supermassive black holes (SMBHs) over cosmic time remains particularly challenging for the low mass (M_BH<10^8 M_sun) population at z>1. This pop…
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…
The Open mulTiwavelength Transient Event Repository (OTTER): Infrastructure Release and Tidal Disruption Event Catalog
Noah Franz, Kate D Alexander, Sebastian Gomez +10
Multiwavelength analyses of astrophysical transients are essential for understanding the physics of these events. To make such analyses more efficient and effective, we present the…
An Agnostic Approach to Building Empirical Type Ia Supernova Light Curves: Evidence for Intrinsic Chromatic Flux Variation Using Nearby Supernova Factory Data
Jared Hand, A. G. Kim, G. Aldering +35
We present a new empirical Type Ia supernova (SN Ia) model with three chromatic flux variation templates: one phase dependent and two phase independent. No underlying dust extincti…
The First Photometric Evidence of a Transient/Variable Source at z>5 with JWST
Christa DeCoursey, Eiichi Egami, Fengwu Sun +27
The James Webb Space Telescope (JWST) discovered 79 transients out to 4.8 through the JADES Transient Survey (JTS), but the JTS did not find any 5 transients. Here,…
JWST Discovery of a High-Redshift Tidal Disruption Event Candidate in COSMOS-Web
Mitchell Karmen, Suvi Gezari, Erini Lambrides +26
The rates and properties of tidal disruption events (TDEs) provide valuable insights into their host galaxy central stellar densities and the demographics of their central supermas…
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…
The Type I Superluminous Supernova Catalog I: Light Curve Properties, Models, and Catalog Description
Sebastian Gomez, Matt Nicholl, Edo Berger +25
We present the most comprehensive catalog to date of Type I Superluminous Supernovae (SLSNe), a class of stripped envelope supernovae (SNe) characterized by exceptionally high lumi…
Discovery of a Relativistic Stripped Envelope Type Ic-BL Supernova at z = 2.83 with JWST
M. R. Siebert, C. Decoursey, D. A. Coulter +26
We present JWST NIRCam and NIRSpec observations of a Type Ic supernova (SN Ic) and its host galaxy (JADES-GS+53.13533-27.81457) at . This SN (named SN 2023adta) was ident…
Roman CCS White Paper: Characterizing Superluminous Supernovae with Roman
Sebastian Gomez, Kate Alexander, Edo Berger +16
Type-I Superluminous Supernovae (SLSNe) are an exotic class of core-collapse SN (CCSN) that can be up to 100 times brighter and more slowly-evolving than normal CCSNe. SLSNe repres…
