Candidate Tidal Disruption Event AT2019fdr Coincident with a High-Energy Neutrino
Simeon Reusch, Robert Stein, Marek Kowalski +46
The origins of the high-energy cosmic neutrino flux remain largely unknown. Recently, one high-energy neutrino was associated with a tidal disruption event (TDE). Here we present A…
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…
Seventeen Tidal Disruption Events from the First Half of ZTF Survey Observations: Entering a New Era of Population Studies
Sjoert van Velzen, Suvi Gezari, Erica Hammerstein +34
While tidal disruption events (TDEs) have long been heralded as laboratories for the study of quiescent black holes, the small number of known TDEs and uncertainties in their emiss…
The first tidal disruption flare in ZTF: from photometric selection to multi-wavelength characterization
Sjoert van Velzen, Suvi Gezari, S. Bradley Cenko +37
We present Zwicky Transient Facility (ZTF) observations of the tidal disruption flare AT2018zr/PS18kh reported by Holoien et al. and detected during ZTF commissioning. The ZTF ligh…
Understanding Type Ia supernovae through their U-band spectra
J. Nordin, G. Aldering, P. Antilogus +39
Context. Observations of Type Ia supernovae (SNe Ia) can be used to derive accurate cosmological distances through empirical standardization techniques. Despite this success neithe…
