Not So Heavy Metal I: Low Metallicity Enhances the Rate of high-redshift Superluminous Supernovae

Ben Margalit, Allison L. Strom, Cristina Andrade +4

Type-I superluminous supernovae (SLSNe) are extremely luminous stellar explosions originating from the core collapse of massive stars. Unlike normal core-collapse supernovae, howev…

Lightcurve Modelling of 2,205 ZTF DR2 Type~Ia Supernovae: Implications for SN Ia Physics and Cosmology

Nikhil Sarin, Ellen Lindsjö, Lisa Kelsey +11

We fit the multi-band light curves of 2,205 Type Ia supernovae (SNe~Ia) from the Zwicky Transient Facility DR2 with a one-zone radioactive decay model with a phenomenological addit…

ZTF25abjmnps (AT2025ulz) and S250818k: A Candidate Superkilonova from a Sub-threshold Sub-Solar Gravitational Wave Trigger

Mansi M. Kasliwal, Tomas Ahumada, Robert Stein +61

On August 18, 2025, the LIGO-Virgo-KAGRA collaboration reported gravitational waves from a sub-threshold binary neutron star merger. If astrophysical, this event would have a surpr…

Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. I: Luminosity Function, Volumetric Rate

Kaustav K. Das, Mansi M. Kasliwal, Christoffer Fremling +51

We present the luminosity function and volumetric rate of a sample of Type IIP supernovae (SNe) from the Zwicky Transient Facility Census of the Local Universe survey (CLU). This i…

SN 2023zaw: an ultra-stripped, nickel-poor supernova from a low-mass progenitor

Kaustav K. Das, Christoffer Fremling, Mansi M. Kasliwal +34

We present SN 2023zaw a sub-luminous ( mag) and rapidly-evolving supernova ( days), with the lowest nickel mass (…

Dramatic rebrightening of the type-changing stripped-envelope supernova SN 2023aew

Yashvi Sharma, Jesper Sollerman, Shrinivas R. Kulkarni +32

Multi-peaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-s…

Star formation and morphological properties of galaxies in the Pan-STARRS survey- I. A machine learning approach to galaxy and supernova classification

A. Baldeschi, A. Miller, M. Stroh +2

We present a classification of galaxies in the Pan-STARRS1 (PS1) 3 survey based on their recent star formation history and morphology. Specifically, we train and test two Random…

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…
