We present deep Apache Point Observatory optical observations within seconds of the outburst of the periodic fast radio burst (FRB) 180916.J0158+65 obtained on 3 September 2020. FR…
SN 2019muj -- a well-observed Type Iax supernova that bridges the luminosity gap of the class
Barnabás Barna, Tamás Szalai, Saurabh W. Jha +38
We present early-time ( days) observations of SN 2019muj (= ASASSN-19tr), one of the best-observed members of the peculiar SN Iax class. Ultraviolet and optical photometri…
A Common Origin for Low Mass Ratio Events Observed by LIGO and Virgo in the First Half of the Third Observing Run
Mohammadtaher Safarzadeh, Daniel Wysocki
In its third observing run, the LIGO/Virgo collaboration has announced a potential neutron star-black hole (NSBH) merger candidate, GW190426_152155. Together with GW190814, these t…
What determines the structure of short gamma-ray burst jets?
Gerardo Urrutia, Fabio De Colle, Ariadna Murguia-Berthier +1
The discovery of GRB 170817A, the first unambiguous off-axis short gamma-ray burst arising from a neutron star merger, has challenged our understanding of the angular structure of…
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…
Comparing inclination dependent analyses of kilonova transients
J. Heinzel, M. W. Coughlin, T. Dietrich +7
The detection of AT2017gfo proved that binary neutron star mergers are progenitors of kilonovae. Using a combination of numerical-relativity and radiative-transfer simulations, the…
Formation of GW190521 via gas accretion onto Population III stellar black hole remnants born in high-redshift minihalos
Mohammadtaher Safarzadeh, Zoltán Haiman
The recent gravitational wave merger event, GW190521, has challenged our understanding of the stellar-mass black hole (BH) formation. The primary and secondary BH are both inferred…
