An Automated Probabilistic Asteroid Prediscovery Pipeline
Sage Li, Alex Geringer-Sameth, Nathan Golovich
We present an automated and probabilistic method to make prediscovery detections of near-Earth asteroids (NEAs) in archival survey images, with the goal of reducing orbital uncerta…
Multi-year stacking searches for solar system bodies
Alex Geringer-Sameth, Nathan Golovich, Keita Iwabuchi
Digital tracking detects faint solar system bodies by stacking many images along hypothesized orbits, revealing objects that are undetectable in every individual exposure. Previous…
Survey-Wide Asteroid Discovery with a High-Performance Computing Enabled Non-Linear Digital Tracking Framework
Nathan Golovich, Trevor Steil, Alex Geringer-Sameth +3
Modern astronomical surveys detect asteroids by linking together their appearances across multiple images taken over time. This approach faces limitations in detecting faint astero…
MEGASIM: Distribution and Detection of Earth Trojan Asteroids
Travis Yeager, Nathan Golovich, Kerianne Pruett
Using N-body simulation results from the MEGASIM dataset, we present spatial distributions of Earth Trojan Asteroids and assess the detectability of the population in current and n…
On the Need for a Near-Earth Object Characterization Constellation in Low-Earth Orbit
Nathan Golovich
In 2005, the United States Congress passed a bill mandating the detection, tracking, cataloguing and characterization of 90\% of the 140 meter and larger near-Earth objects (NEOs)…
MEGASIM: Lifetimes and Resonances of Earth Trojan Asteroids -- The Death of Primordial ETAs?
Travis Yeager, Nathan Golovich
We present an analysis of lifetimes and resonances of Earth Trojan Asteroids (ETAs) in the MEGASIM data set (Yeager & Golovich 2022). Trojan asteroids co-orbit the Sun with a plane…
A New Blind Asteroid Detection Scheme
Nathan Golovich, Noah Lifset, Robert Armstrong +3
As astronomical photometric surveys continue to tile the sky repeatedly, the potential to pushdetection thresholds to fainter limits increases; however, traditional digital-trackin…
Time-series and Phasecurve Photometry of Episodically-Active Asteroid (6478) Gault in a Quiescent State Using APO, GROWTH, P200 and ZTF
Josiah N. Purdum, Zhong-Yi Lin, Bryce T. Bolin +49
We observed Episodically Active Asteroid (6478) Gault in 2020 with multiple telescopes in Asia and North America and have found that it is no longer active after its recent outburs…
A Search for L4 Earth Trojan Asteroids Using a Novel Track-Before-Detect Multi-Epoch Pipeline
Noah Lifset, Nathan Golovich, Eric Green +2
Earth Trojan Asteroids are an important but elusive population that co-orbit with Earth at the L4 and L5 Lagrange points. There is only one known, but a large population is theoret…
