ZTF-observed late-time signals of pre-ZTF transients
Jacco H. Terwel, Kate Maguire, Jesper Sollerman +6
With large-scale surveys such as the Zwicky Transient Facility (ZTF), it has become possible to obtain a well-sampled light curve spanning the full length of the survey for any dis…
In Search of the Potentially Hazardous Asteroids in the Taurid Resonant Swarm
Jasmine Li, Quanzhi Ye, Denis Vida +8
The Taurid Complex is a large interplanetary system that contains comet 2P/Encke, several meteoroid streams, and possibly a number of near-Earth asteroids. The size and nature of t…
A Massive Black Hole 0.8 kpc from the Host Nucleus Revealed by the Offset Tidal Disruption Event AT2024tvd
