Multi-messenger constraints on the Hubble constant through combination of gravitational waves, gamma-ray bursts and kilonovae from neutron star mergers
Mattia Bulla, Michael W. Coughlin, Suhail Dhawan +1
The simultaneous detection of gravitational waves and light from the binary neutron star merger GW170817 led to independent measurements of distance and redshift, providing a direc…
The detection efficiency of type Ia supernovae from the Zwicky Transient Facility: Limits on the intrinsic rate of early flux excesses
M. R. Magee, C. Cuddy, K. Maguire +8
Samples of young type Ia supernovae have shown `early excess' emission in a few cases. Similar excesses are predicted by some explosion and progenitor scenarios and hence can provi…
The Final Season Reimagined: 30 Tidal Disruption Events from the ZTF-I Survey
Erica Hammerstein, Sjoert van Velzen, Suvi Gezari +30
Tidal disruption events (TDEs) offer a unique way to study dormant black holes. While the number of observed TDEs has grown thanks to the emergence of wide-field surveys in the pas…
Supernova Siblings and their Parent Galaxies in the Zwicky Transient Facility Bright Transient Surve
M. L. Graham, C. Fremling, D. A. Perley +19
Supernova (SN) siblings -- two or more SNe in the same parent galaxy -- are useful tools for exploring progenitor stellar populations as well as properties of the host galaxies suc…
Less than 1% of Core-Collapse Supernovae in the local universe occur in elliptical galaxies
I. Irani, S. J. Prentice, S. Schulze +39
We present observations of three Core-collapse supernovae (CCSNe) in elliptical hosts, detected by the Zwicky Transient Facility Bright Transient Survey (BTS). SN 2019ape is a SN I…
A large fraction of hydrogen-rich supernova progenitors experience elevated mass loss shortly prior to explosion
Rachel J. Bruch, Avishay Gal-Yam, Steve Schulze +43
Spectroscopic detection of narrow emission lines traces the presence of circumstellar mass distributions around massive stars exploding as core-collapse supernovae. Transient emiss…
