ZTF SN Ia DR2 follow-up: Characterization of subluminous Type Ia supernovae in the ZTF DR2 full sample
Alaa Alburai, Lluís Galbany, Umut Burgaz +19
The Zwicky Transient Facility Data Release 2 (ZTF DR2) includes a total of 3,628 Type Ia supernovae (SNe~Ia), providing the largest and most complete sample of spectroscopically co…
A New FU Orionis Accretion Outburst in the W5 HII Region
Lynne A. Hillenbrand, Matthew J. Graham, Mansi M. Kasliwal +9
We announce a recently detected outburst that is currently only a few months old, and probably of FU Orionis type. The progenitor to the outburst was an emission-line, flat-spectru…
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…
AppleCiDEr. II. SpectraNet: A Spectroscopic Neural Network Classifier for Transients Demonstrated on ZTF Follow-up Data
Maojie Xu, Argyro Sasli, Alexandra Junell +21
Time-domain surveys such as the Zwicky Transient Facility have opened a new frontier in the discovery and characterization of transients. While photometric light curves provide bro…
An Extremely Luminous Flare Recorded from a Supermassive Black Hole
Matthew J. Graham, Barry McKernan, K. E. Saavik Ford +17
Since their discovery more than 60 years ago, accreting supermassive black holes in active galactic nuclei (AGN) were recognized as highly variable sources, requiring an extremely…
Prediscovery Activity of New Interstellar Object 3I/ATLAS: A Dynamically-Old Comet?
Quanzhi Ye, Michael S. P. Kelley, Henry H. Hsieh +9
We report on the prediscovery observations and constraints of the new interstellar comet 3I/2025 N1 (ATLAS), made by the Zwicky Transient Facility (ZTF), for the inbound leg of the…
SN 2021aaev: a Hydrogen-Rich Superluminous Supernova with Early Flash and Long-Lived Circumstellar Interaction in an Unusual Host Environment
Yang Hu, Ragnhild Lunnan, Priscila J. Pessi +25
We present photometric and spectroscopic observations of SN\,2021aaev, a hydrogen-rich, superluminous supernova with persistent (at least days) narrow Balmer lines (SLSN-…
IIb or not IIb: A Catalog of ZTF Kilonova Imposters
Tyler Barna, Christoffer Fremling, Tomas Ahumada +12
Among the various classes of fast optical transients (FOTs), kilonovae (KNe), which can emerge as a result of neutron star mergers, are extremely challenging to observe because of…
LIGO/Virgo/KAGRA neutron star merger candidate S250206dm: Zwicky Transient Facility observations
Tomás Ahumada, Shreya Anand, Mattia Bulla +49
We present the searches conducted with the Zwicky Transient Facility (ZTF) in response to S250206dm, a bona fide event with a false alarm rate of one in 25 years, detected by the I…
Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. II: Lightcurve Analysis
Kaustav K. Das, Mansi M. Kasliwal, Jesper Sollerman +18
The Zwicky Transient Facility Census of the Local Universe survey yielded a sample of 330 Type IIP supernovae (SNe) with well-constrained peak luminosities. In paper I (arXiv:2502.…
A luminous and hot infrared through X-ray transient at a 5 kpc offset from a dwarf galaxy
Jean J. Somalwar, Vikram Ravi, Raffaella Margutti +20
We are searching for hot, constant-color, offset optical flares in the Zwicky Transient Facility (ZTF) data stream that are from any galaxy in public imaging data from th…
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…
Inferring CSM Properties of Type II SNe Using a Magnitude-Limited ZTF Sample
K-Ryan Hinds, Daniel Perley, Jesper Sollerman +20
Although all Type II supernovae (SNe) originate from massive stars possessing a hydrogen-rich envelope, their light curve morphology is diverse, reflecting poorly characterised het…
A Luminous Red Optical Flare and Hard X-ray Emission in the Tidal Disruption Event AT2024kmq
Anna Y. Q. Ho, Yuhan Yao, Tatsuya Matsumoto +30
We present the optical discovery and multiwavelength follow-up observations of AT2024kmq, a likely tidal disruption event (TDE) associated with a supermassive ($M_{\rm BH}\sim 10^{…
