The Zwicky Transient Facility: Data Processing, Products, and Archive
Frank J. Masci, Russ R. Laher, Ben Rusholme +46
The Zwicky Transient Facility (ZTF) is a new robotic time-domain survey currently in progress using the Palomar 48-inch Schmidt Telescope. ZTF uses a 47 square degree field with a…
Discovery of an intermediate-luminosity red transient in M51 and its likely dust-obscured, infrared-variable progenitor
Jacob E. Jencson, Scott M. Adams, Howard E. Bond +49
We present the discovery of an optical transient (OT) in Messier 51, designated M51 OT2019-1 (also ZTF19aadyppr, AT 2019abn, ATLAS19bzl), by the Zwicky Transient Facility (ZTF). Th…
Optimal strategies for observation of active galactic nuclei variability with Imaging Atmospheric Cherenkov Telescopes
Matteo Giomi, Lucie Gerard, Gernot Maier
Variable emission is one of the defining characteristic of active galactic nuclei (AGN). While providing precious information on the nature and physics of the sources, variability…
Estimate of the Fermi Large Area Telescope sensitivity to gamma-ray polarization
Matteo Giomi, Rolf Bühler, Carmelo Sgrò +2
Although not designed primarily as a polarimeter, the \textit{Fermi}-Large Area Telescope (LAT) has the potential to detect high degrees of linear polarization from some of the bri…
The Zwicky Transient Facility: System Overview, Performance, and First Results
Eric C. Bellm, Shrinivas R. Kulkarni, Matthew J. Graham +112
The Zwicky Transient Facility (ZTF) is a new optical time-domain survey that uses the Palomar 48-inch Schmidt telescope. A custom-built wide-field camera provides a 47 deg fiel…
Towards Efficient Detection of Small Near-Earth Asteroids Using the Zwicky Transient Facility (ZTF)
Quanzhi Ye, Frank J. Masci, Hsing Wen Lin +23
We describe ZStreak, a semi-real-time pipeline specialized in detecting small, fast-moving near-Earth asteroids (NEAs) that is currently operating on the data from the newly-commis…
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…
The imprint of pulsar parameters on the morphology of Pulsar Wind Nebulae
Rolf Buehler, Matteo Giomi
The morphology of young Pulsar Wind Nebulae (PWN) is largely determined by the properties of the wind injected by the pulsar. We have used a recent parametrization of the wind obta…
A Unified Framework for Quantifying Privacy Risk in Synthetic Data
Matteo Giomi, Franziska Boenisch, Christoph Wehmeyer +1
Synthetic data is often presented as a method for sharing sensitive information in a privacy-preserving manner by reproducing the global statistical properties of the original data…
General relativistic orbital decay in a seven-minute-orbital-period eclipsing binary system
Kevin B. Burdge, Michael W. Coughlin, Jim Fuller +23
General relativity predicts that short orbital period binaries emit significant gravitational radiation, and the upcoming Laser Interferometer Space Antenna (LISA) is expected to d…
GROWTH on S190425z: Searching thousands of square degrees to identify an optical or infrared counterpart to a binary neutron star merger with the Zwicky Transient Facility and Palomar Gattini IR
Michael W. Coughlin, Tomás Ahumada, Shreya Anand +76
The third observing run by LVC has brought the discovery of many compact binary coalescences. Following the detection of the first binary neutron star merger in this run (LIGO/Virg…
A New Class of Changing-Look LINERs
Sara Frederick, Suvi Gezari, Matthew J. Graham +28
We report the discovery of six active galactic nuclei (AGN) caught "turning on" during the first nine months of the Zwicky Transient Facility (ZTF) survey. The host galaxies were c…
A new class of pulsating hot subdwarfs
Thomas Kupfer, Evan B. Bauer, Kevin B. Burdge +22
Using high-cadence observations from the Zwicky Transient Facility at low Galactic latitudes, we have discovered a new class of pulsating, hot, compact stars. We have found four ca…
Seventeen Tidal Disruption Events from the First Half of ZTF Survey Observations: Entering a New Era of Population Studies
Sjoert van Velzen, Suvi Gezari, Erica Hammerstein +34
While tidal disruption events (TDEs) have long been heralded as laboratories for the study of quiescent black holes, the small number of known TDEs and uncertainties in their emiss…
