Neutrino follow-up with the Zwicky Transient Facility: Results from the first 24 campaigns
Robert Stein, Simeon Reusch, Anna Franckowiak +33
The Zwicky Transient Facility (ZTF) performs a systematic neutrino follow-up program, searching for optical counterparts to high-energy neutrinos with dedicated Target-of-Opportuni…
Time-series and Phasecurve Photometry of Episodically-Active Asteroid (6478) Gault in a Quiescent State Using APO, GROWTH, P200 and ZTF
Josiah N. Purdum, Zhong-Yi Lin, Bryce T. Bolin +49
We observed Episodically Active Asteroid (6478) Gault in 2020 with multiple telescopes in Asia and North America and have found that it is no longer active after its recent outburs…
Initial Characterization of Active Transitioning Centaur, P/2019 LD2 (ATLAS), using Hubble, Spitzer, ZTF, Keck, APO and GROWTH Visible & Infrared Imaging and Spectroscopy
Bryce T. Bolin, Yanga R. Fernandez, Carey M. Lisse +43
We present visible and mid-infrared imagery and photometry of temporary Jovian co-orbital comet P/2019 LD taken with HST/WFC3, Spitzer/IRAC, the GROWTH telescope network, visib…
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…
Two stripped envelope supernovae with circumstellar interaction -- but only one really shows it
J. Sollerman, C. Fransson, C. Barbarino +23
We present SN 2019tsf (ZTF19ackjszs) and SN 2019oys (ZTF19abucwzt). These two stripped envelope Type Ib supernovae suddenly showed a (re-)brightening in their late light curves. We…
Characterization of Temporarily-Captured Minimoon 2020 CD by Keck Time-resolved Spectrophotometry
Bryce T. Bolin, Christoffer Fremling, Timothy R. Holt +42
We present time-resolved visible spectrophotometry of minimoon 2020 CD, the second asteroid known to become temporarily captured by the Earth-Moon system's gravitational field.…
The Zwicky Transient Facility: Observing System
Richard Dekany, Roger M. Smith, Reed Riddle +23
The Zwicky Transient Facility (ZTF) Observing System (OS) is the data collector for the ZTF project to study astrophysical phenomena in the time domain. ZTF OS is based upon the 48…
SN 2020bqj: a Type Ibn supernova with a long lasting peak plateau
E. C. Kool, E. Karamehmetoglu, J. Sollerman +31
Context: Type Ibn supernovae are a rare class of stripped envelope supernovae interacting with a helium-rich CSM. The majority of the SNe Ibn reported display a surprising homogene…
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…
Candidate Electromagnetic Counterpart to the Binary Black Hole Merger Gravitational Wave Event S190521g
M. J. Graham, K. E. S. Ford, B. McKernan +24
We report the first plausible optical electromagnetic (EM) counterpart to a (candidate) binary black hole (BBH) merger. Detected by the Zwicky Transient Facility (ZTF), the EM flar…
A non-equipartition shockwave traveling in a dense circumstellar environment around SN2020oi
Assaf Horesh, Itai Sfaradi, Mattias Ergon +34
We report the discovery and panchromatic followup observations of the young Type Ic supernova, SN2020oi, in M100, a grand design spiral galaxy at a mere distance of Mpc. We fo…
A Search for Extra-Tidal RR Lyrae in the Globular Cluster NGC 5024 and NGC 5053
Chow-Choong Ngeow, Justin Belecki, Rick Burruss +9
Recently, Kundu et al (2019) reported that the globular cluster NGC 5024 (M53) possesses five extra-tidal RR Lyrae. In fact, four of them were instead known members of a nearby glo…
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…
Characterization of the Nucleus, Morphology and Activity of Interstellar Comet 2I/Borisov by Optical and Near-Infrared GROWTH, Apache Point, IRTF, ZTF and Keck Observations
Bryce T. Bolin, Carey M. Lisse, Mansi M. Kasliwal +52
We present visible and near-infrared photometric and spectroscopic observations of interstellar object 2I/Borisov taken from 2019 September 10 to 2019 November 29 using the GROWTH,…
