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 47 deg2 field of view and 8 s readout time, yielding more than an order magnitude improvement in speed relative to its predecessor survey, Factory. We describe design implementation observing system. ZTF data system at Infrared Processing Analysis Center near-real-time reduction identify moving varying objects. outline analysis...
The Zwicky Transient Facility (ZTF), a public-private enterprise, is new time domain survey employing dedicated camera on the Palomar 48-inch Schmidt telescope with 47 deg$^2$ field of view and 8 second readout time. It well positioned in development astronomy, offering operations at 10% scale style Large Synoptic Survey Telescope (LSST) single 1-m class telescope. public surveys will cover observable northern sky every three nights g r filters visible Galactic plane night r.

The debiased absolute-magnitude and orbit distributions as well source regions for near-Earth objects (NEOs) provide a fundamental frame of reference studies individual NEOs more complex population-level questions. We present new four-dimensional model the NEO population that describes steady-state semimajor axis, eccentricity, inclination, absolute magnitude $H$ in range $17<H<25$. modeling approach improves upon methodology originally developed by Bottke et al. (2000; Science 288,...
Abstract Classical gamma-ray bursts (GRBs) have two distinct emission episodes: prompt from ultrarelativistic ejecta and afterglow shocked circumstellar material. While both components are extremely luminous in known GRBs, a variety of scenarios predict the existence with little or no associated high-energy emission. We present AT 2019pim, first spectroscopically confirmed observed to be identified. Serendipitously discovered during follow-up observations gravitational-wave trigger located...
We describe the Pan-STARRS Moving Object Processing System (MOPS), a modern software package that produces automatic asteroid discoveries and identifications from catalogs of transient detections next-generation astronomical survey telescopes. MOPS achieves > 99.5% efficiency in producing orbits synthetic but realistic population asteroids whose measurements were simulated for Pan-STARRS4-class telescope. Additionally, using non-physical grid population, we demonstrate can detect populations...
We report on $g$, $r$ and $i$ band observations of the Interstellar Object 'Oumuamua (1I) taken 2017 October 29 from 04:28 to 08:40 UTC by Apache Point Observatory (APO) 3.5m telescope's ARCTIC camera. find that 1I's colors are $g-r=0.41\pm0.24$ $r-i=0.23\pm0.25$, consistent with visible spectra Masiero (2017), Ye et al.

A quarter of known asteroids is associated with more than 100 distinct asteroid families, meaning that these originate as impact fragments from the family parent bodies. The determination which remaining population are members undiscovered or accreted planetesimals protoplanetary disk, would constrain a critical phase planetary formation by unveiling unknown planetesimal size distribution. We discovered 4-billion-year-old extending across entire inner part main belt whose include most dark...
The near-Earth asteroid (3200) Phaethon is an intriguing object: its perihelion at only 0.14 au and associated with the Geminid meteor stream. We aim to use all available disk-integrated optical data derive a reliable convex shape model of Phaethon. By interpreting space- ground-based thermal infrared Spitzer spectra using thermophysical model, we also further constrain size, inertia, visible geometric albedo. applied inversion method new obtained by six instruments previous observations....
Abstract Near-Earth Objects (NEOs) are a transient population of small bodies with orbits near or in the terrestrial planet region. They represent mid-stage dynamical cycle asteroids and comets, which starts their removal from respective source regions—the main belt trans-Neptunian scattered disk—and ends as impact planets, disintegrate Sun, ejected solar system. Here we develop new orbital model NEOs by numerically integrating asteroid main-belt sources calibrating results on observations...
The Vera C. Rubin Observatory is expected to start the Legacy Survey of Space and Time (LSST) in early mid-2025. This multi-band wide-field synoptic survey will transform our view solar system, with discovery monitoring over 5 million small bodies.The final strategy chosen for LSST has direct implications on discoverability characterization system minor planets passing interstellar objects.

Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques, YORP, to be a notable factor in their evolution. (152830) Dinkinesh is asteroid orbiting the Sun near inner edge of Main Asteroid Belt heliocentric semimajor axis 2.19 AU; its S type spectrum typical bodies this part Belt. Here we report observations by Lucy spacecraft as it passed within 431 Dinkinesh. revealed Dinkinesh, which has an effective diameter only $\sim$720 m,...
Comet 2I/Borisov, the first unambiguous interstellar comet ever found, was discovered in August 2019 at $\sim3$ au from Sun on its inbound leg. No pre-discovery detection beyond 3 has yet been reported, mostly due to comet's proximity as seen Earth. Here we present a search for detections of Borisov using images taken by Catalina Sky Survey (CSS), Pan-STARRS and Zwicky Transient Facility (ZTF), with further comprehensive follow-up campaign being presented \citet{Bolin2019}. We identified ZTF...

Context. Asteroid families are the outcomes of disruption or cratering events on a size and energy scales that not reproducible in laboratory experiments. Overall structure, as well properties individual members, old could have been changed since their formation. Therefore young preserve best characteristics initial event.
