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-inch aperture Schmidt-type design Samuel Oschin Telescope at the Palomar Observatory in Southern California. It incorporates new telescope aspheric corrector optics, dome and telescope drives, a large-format exposure shutter, a flat-field illumination system, a robotic bandpass filter exchanger, and the key element… Expand

TLDR
The initial results of the Tails efficiency evaluation in a production setting on the data of the ZTF Twilight survey are reported, including the first AI-assisted discovery of a Comet (C/2020 T2) and the recovery of a comet (P/2016 J3 = P/2021 A3). Expand
General-purpose software for managing astronomical observing programs in the LSST era
TLDR
A project to develop a general-purpose software toolkit that will enable astronomers to easily build TOM systems that they can customize to suit their needs is presented, while a professionally-developed codebase will ensure that the systems are capable of scaling to future programs. Expand
Optimizing serendipitous detections of kilonovae: cadence and filter selection
The rise of multi-messenger astronomy has brought with it the need to exploit all available data streams and learn more about the astrophysical objects that fall within its breadth. One possibleExpand
The abstract observatory: an interface for networking telescopes
TLDR
A generalised model for representing a telescope of arbitrary complexity as a networked resource that could be scheduled by a remote entity is discussed, using the SOAR 4.1m into the Las Cumbres Observatory (LCOGT) robotic telescope network. Expand
A Real-time Automatic Validation System for Optical Transients detected by GWAC
TLDR
A Real-time Automatic transient Validation System (RAVS), capable of automatically carrying out all operations in real-time without human intervention, including the validation of transient candidates, the adaptive light-curve sampling for identified targets in multi-band, and the pushing of observation results to the mobile client.
