TransitNet: A Compact Attention-Augmented Deep Learning Framework for Low-SNR Transit Blind Searches
Xingchen Yan, Jian Ge, Qingtian Liu +3
Motivated by the observational incompleteness of intermediate-to-long-period Earth-size planets, we present TransitNet, a compact attention-augmented deep-learning framework for lo…
GTLS: A GPU-accelerated method for periodic transit detection
Quanquan Hu, Jian Ge, Luoxi Jin +1
Computational efficiency is a critical requirement for transit searches in modern large-scale photometric surveys. We present Graphics Processing Units Transit Least Squares (GTLS)…
DELOS: Contrastive Deep Learning for Low-SNR Blind Transit Searches in Kepler Photometry
Qingtian Liu, Jian Ge, XingChen Yan +4
We present DEtection in phase-folded Light curves with cOntrastive Scoring (DELOS), a deep-learning framework that uses contrastive scoring to perform blind searches for shallow tr…
Detecting Ca II Absorption Lines with a Fe II assisted Dual Neural Network
Lucas Wang, Jian Ge, Kevin Willis
Ca II absorbers, characterized by dusty and metal-rich environments, provide unique insights into the interstellar medium of galaxies. However, their rarity and weak absorption fea…
The GPU Phase Folding and Deep Learning Method for Detecting Exoplanet Transits
Kaitlyn Wang, Jian Ge, Kevin Willis +2
This paper presents GPFC, a novel Graphics Processing Unit (GPU) Phase Folding and Convolutional Neural Network (CNN) system to detect exoplanets using the transit method. We devis…
Discovery of Small Ultra-short-period Planets Orbiting KG Dwarfs in Kepler Survey Using GPU Phase Folding and Deep Learning Detection System
Kaitlyn Wang, Jian Ge, Kevin Willis +3
Of over 5,000 exoplanets identified so far, only a few hundred possess sub-Earth radii. The formation processes of these sub-Earths remain elusive, and acquiring additional samples…
Newly discovered Ca II absorbers in the early universe: statistics, element abundances and dust
Hannah Fang, Iona Xia, Jian Ge +2
We report discoveries of 165 new quasar Ca II absorbers from the Sloan Digital Sky Survey (SDSS) Data Release 7 and 12. Our Ca II rest frame equivalent width distribution supports…
Discovering Ca II Absorption Lines With a Neural Network
Iona Xia, Jian Ge, Kevin Willis +1
Quasar absorption line analysis is critical for studying gas and dust components and their physical and chemical properties as well as the evolution and formation of galaxies in th…
Discovering Faint and High Apparent Motion Rate Near-Earth Asteroids Using A Deep Learning Program
Franklin Wang, Jian Ge, Kevin Willis
Although many near-Earth objects have been found by ground-based telescopes, some fast-moving ones, especially those near detection limits, have been missed by observatories. We de…
ET White Paper: To Find the First Earth 2.0
Jian Ge, Hui Zhang, Weicheng Zang +163
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time,…
Chemo-kinematics of the Milky Way from the SDSS-III MARVELS Survey
Nolan Grieves, Jian Ge, Neil Thomas +20
Combining stellar atmospheric parameters, such as effective temperature, surface gravity, and metallicity, with barycentric radial velocity data provides insight into the chemo-dyn…
Exploring the Brown Dwarf Desert: New Substellar Companions from the SDSS-III MARVELS Survey
Nolan Grieves, Jian Ge, Neil Thomas +27
Planet searches using the radial velocity technique show a paucity of companions to solar-type stars within ~5 AU in the mass range of ~10 - 80 M. This deficit, know…
