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...

In the history of astronomy, major advances in our understanding Universe have come from dramatic improvements ability to accurately measure astronomical quantities. Aided by rapid progress information technology, current sky surveys are changing way we view and study Universe. Next- generation will maintain this revolutionary progress.

The transneptunian objects (TNOs) trapped in mean-motion resonances with Neptune were likely emplaced there during planet migration late the giant-planet formation process. We perform detailed modelling of resonant detected Canada-France Ecliptic Plane Survey (CFEPS) order to provide population estimates and, for some resonances, constrain complex internal orbital element distribution. Detection biases play a critical role because phase relationships make object discovery more at certain...
The Large Synoptic Survey Telescope (LSST) is a large-aperture, wide-field, ground-based survey system that will image the sky in six optical bands from 320 to 1050 nm, uniformly covering approximately $18,000$deg$^2$ of over 800 times.

Once operational, explore wide range astrophysical questions, discovering "killer" asteroids examining nature Dark Energy. generate average 15 TB data per night,...
Abstract The Outer Solar System Origins Survey (OSSOS), a wide-field imaging program in 2013–2017 with the Canada–France–Hawaii Telescope, surveyed 155 deg 2 of sky to depths m r = 24.1–25.2. We present 838 outer solar system discoveries that are entirely free ephemeris bias. This increases inventory trans-Neptunian objects (TNOs) accurately known orbits by nearly 50%. Each minor planet has 20–60 Gaia /Pan-STARRS-calibrated astrometric measurements made over 2–5 oppositions, which allows...
The Large Synoptic Survey Telescope is designed to provide an unprecedented optical imaging dataset that will support investigations of our Solar System, Galaxy and Universe, across half the sky over ten years repeated observation. However, exactly how LSST observations be taken (the observing strategy or "cadence") not yet finalized. In this dynamically-evolving community white paper, we explore detailed performance anticipated science expected depend on small changes strategy. Using...

Vera C. Rubin Observatory is a ground-based astronomical facility under construction, joint project of the National Science Foundation and U.S. Department Energy, designed to conduct multi-purpose 10-year optical survey southern hemisphere sky: Legacy Survey Space Time. Significant flexibility in strategy remains within constraints imposed by core science goals probing dark energy matter, cataloging Solar System, exploring transient sky, mapping Milky Way.

We use SDSS photometry of 73 million stars to simultaneously obtain best-fit main-sequence stellar energy distribution (SED) and amount dust extinction along the line sight towards each star. Using a subsample 23 with 2MASS photometry, whose addition enables more robust results, we show that alone is sufficient break degeneracies between intrinsic color when shape curve fixed. When using both ratio total selective absorption, $R_V$, can be determined an uncertainty about 0.1 for most in...

It will generate multi-petabyte archive images and catalogs astrophysical sources from which wide variety high-precision statistical studies can be undertaken. To accomplish these goals, project has developed suite modeling simulation tools for use in validating that design as-delivered components system yield data products with required properties.
