Quadratic shift-and-stack for Ground-Based Optical Detection of Faint Cislunar Objects
Qi Li, Yuhui Zhao, Chengxing Zhai +2
Detecting faint objects in cislunar space using ground-based optical telescopes is difficult because of their low brightness, strong lunar background, and complex, nonlinear appare…
Near-Earth Object Observations using Synthetic Tracking
Chengxing Zhai, Michael Shao, Navtej Saini +5
Synthetic tracking (ST) has emerged as a potent technique for observing fast-moving near-Earth objects (NEOs), offering enhanced detection sensitivity and astrometric accuracy by a…
Micro-arcsecond Astrometry Technology: Detector and Field Distortion Calibration
Michael Shao, Chengxing Zhai, Bijan Nemati +3
Microarcsecond (uas) astrometry is an indispensable technique to detect earth-like exoplanets, fully characterize exoplanetary orbits, and measure their masses --information critic…
Synthetic tracking using ZTF Long Dwell Datasets
Chengxing Zhai, Quanzhi Ye, Michael Shao +4
The Zwicky Transit Factory (ZTF) is a powerful time domain survey facility with a large field of view. We apply the synthetic tracking technique to integrate a ZTF's long-dwell dat…
All-Sky Near Infrared Space Astrometry
Barbara McArthur, David Hobbs, Erik Høg +20
Gaia is currently revolutionizing modern astronomy. However, much of the Galactic plane, center and the spiral arm regions are obscured by interstellar extinction, rendering them i…
Accurate Ground-based Near-Earth-Asteroid Astrometry using Synthetic Tracking
Chengxing Zhai, Michael Shao, Navtej S. Saini +13
Accurate astrometry is crucial for determining orbits of near-Earth-asteroids (NEAs) and therefore better tracking them. This paper reports on a demonstration of 10 milliarcsecond-…
