Census of R Coronae Borealis stars I: Infrared light curves from Palomar Gattini IR
Viraj R. Karambelkar, Mansi M. Kasliwal, Patrick Tisserand +16
We are undertaking the first systematic infrared (IR) census of R Coronae Borealis (RCB) stars in the Milky Way, beginning with IR light curves from the Palomar Gattini IR (PGIR) s…
VLBA discovery of a resolved source in the candidate black hole X-ray binary AT2019wey
Nitika Yadlapalli, Vikram Ravi, Yuhan Yao +2
AT2019wey is a Galactic low mass X-ray binary with a candidate black hole accretor first discovered as an optical transient by ATLAS in December 2019. It was then associated with a…
Multi-wavelength Observations of AT2019wey: a New Candidate Black Hole Low-mass X-ray Binary
Yuhan Yao, S. R. Kulkarni, Kevin B. Burdge +21
AT2019wey (SRGA J043520.9+552226, SRGE J043523.3+552234) is a transient first reported by the ATLAS optical survey in 2019 December. It rose to prominence upon detection, three mon…
A Comprehensive X-ray Report on AT2019wey
Yuhan Yao, S. R. Kulkarni, K. C. Gendreau +25
Here, we present MAXI, SWIFT, NICER, NuSTAR and Chandra observations of the X-ray transient AT2019wey (SRGA J043520.9+552226, SRGE J043523.3+552234). From spectral and timing analy…
Bright, months-long stellar outbursts announce the explosion of interaction-powered supernovae
Nora L. Strotjohann, Eran O. Ofek, Avishay Gal-Yam +53
Interaction-powered supernovae (SNe) explode within an optically-thick circumstellar medium (CSM) that could be ejected during eruptive events. To identify and characterize such pr…
The ZTF Source Classification Project: II. Periodicity and variability processing metrics
Michael W. Coughlin, Kevin Burdge, Dmitry A. Duev +22
The current generation of all-sky surveys is rapidly expanding our ability to study variable and transient sources. These surveys, with a variety of sensitivities, cadences, and fi…
A systematic search of Zwicky Transient Facility data for ultracompact binary LISA-detectable gravitational-wave sources
Kevin B. Burdge, Thomas A. Prince, Jim Fuller +31
Using photometry collected with the Zwicky Transient Facility (ZTF), we are conducting an ongoing survey for binary systems with short orbital periods ( with…
Constraining the Kilonova Rate with Zwicky Transient Facility Searches Independent of Gravitational Wave and Short Gamma-ray Burst Triggers
Igor Andreoni, Erik C. Kool, Ana Sagues Carracedo +34
The first binary neutron star merger, GW170817, was accompanied by a radioactivity-powered optical/infrared transient called a kilonova. To date, no compelling kilonova has been fo…
A new class of Roche lobe-filling hot subdwarf binaries
Thomas Kupfer, Evan B. Bauer, Kevin B. Burdge +30
We present the discovery of the second binary with a Roche lobe-filling hot subdwarf transferring mass to a white dwarf (WD) companion. This 56 minute binary was discovered using d…
Shock Cooling Emission from Extended Material Revisited
Anthony L. Piro, Annastasia Haynie, Yuhan Yao
Following shock breakout, the emission from an astrophysical explosion is dominated by the radiation of shock heated material as it expands and cools, known as shock cooling emissi…
Kilonova Luminosity Function Constraints based on Zwicky Transient Facility Searches for 13 Neutron Star Mergers
Mansi M. Kasliwal, Shreya Anand, Tomas Ahumada +100
We present a systematic search for optical counterparts to 13 gravitational wave (GW) triggers involving at least one neutron star during LIGO/Virgo's third observing run. We searc…
SN2019dge: a Helium-rich Ultra-Stripped Envelope Supernova
Yuhan Yao, Kishalay De, Mansi M. Kasliwal +28
We present observations of ZTF18abfcmjw (SN2019dge), a helium-rich supernova with a fast-evolving light curve indicating an extremely low ejecta mass () and l…
Zwicky Transient Facility constraints on the optical emission from the nearby repeating FRB 180916.J0158+65
Igor Andreoni, Wenbin Lu, Roger M. Smith +16
The discovery rate of fast radio bursts (FRBs) is increasing dramatically thanks to new radio facilities. Meanwhile, wide-field instruments such as the 47 deg Zwicky Transient…
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…
The Zwicky Transient Facility Census of the Local Universe I: Systematic search for Calcium rich gap transients reveal three related spectroscopic sub-classes
Kishalay De, Mansi M. Kasliwal, Anastasios Tzanidakis +47
(Abridged) Using the Zwicky Transient Facility alert stream, we are conducting a large campaign to spectroscopically classify all transients occurring in galaxies in the Census of…
