Discovery of a Fast Iron Low-ionization Outflow in the Early Evolution of the Nearby Tidal Disruption Event AT2019qiz
Tiara Hung, Ryan J. Foley, S. Veilleux +16
We report the results of ultraviolet (UV) and optical photometric and spectroscopic analysis of the tidal disruption event (TDE) AT2019qiz. Our follow-up observations started 10…
TDE Hosts are Green and Centrally Concentrated: Signatures of a Post-Merger System
Erica Hammerstein, Suvi Gezari, Sjoert van Velzen +17
We study the properties of the galaxies hosting the first 19 tidal disruption events (TDEs) detected with the Zwicky Transient Facility (ZTF) within the context of a carefully cons…
A Family Tree of Optical Transients from Narrow-Line Seyfert 1 Galaxies
Sara Frederick, Suvi Gezari, Matthew J. Graham +17
The Zwicky Transient Facility (ZTF) has discovered five new events belonging to an emerging class of AGN undergoing smooth flares with large amplitudes and rapid rise times. This s…
VLBI20-30: a scientific roadmap for the next decade -- The future of the European VLBI Network
Tiziana Venturi, Zsolt Paragi, Michael Lindqvist +77
This white paper describes the science case for Very Long Baseline Interferometry (VLBI) and provides suggestions towards upgrade paths for the European VLBI Network (EVN). The EVN…
A tidal disruption event coincident with a high-energy neutrino
Robert Stein, Sjoert van Velzen, Marek Kowalski +55
Cosmic neutrinos provide a unique window into the otherwise-hidden mechanism of particle acceleration in astrophysical objects. A flux of high-energy neutrinos was discovered in 20…
The Rise and Fall of ASASSN-18pg: Following a TDE from Early To Late Times
Thomas W. -S. Holoien, Katie Auchettl, Michael A. Tucker +29
We present nearly 500 days of observations of the tidal disruption event ASASSN-18pg, spanning from 54 days before peak light to 441 days after peak light. Our dataset includes X-r…
