The GlimmIr: Spectroscopic Variability in a z~7 LRD Indicates Rapid Changes in Both the Narrow and Broad Line Regions
Erini Lambrides, Taylor A. Hutchison, Rebecca L. Larson +39
The enigmatic population of ``Little Red Dots'' (LRDs) sit at the center of some of the largest debates in extragalactic astronomy today. The source(s) of ionizing emission and the…
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 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…
Testing for Intrinsic Type Ia Supernova Luminosity Evolution at z>2 with JWST
J. D. R. Pierel, D. A. Coulter, M. R. Siebert +38
The James Webb Space Telescope} (JWST) is opening new frontiers of transient discovery and follow-up at high-redshift. Here we present the discovery of a spectroscopically confirme…
