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…
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,…
Identifying MgII Narrow Absorption Lines with Deep Learning
Yinan Zhao, Jian Ge, Xiaoyong Yuan +3
Metal absorption line systems in distant quasar spectra probe of the history of gas content in the universe. The MgII 2796, 2803 doublet is one of the most important absorptio…
Studying Quasar Absorber Host Galaxy Properties Using Image Stacking Technique
Bill Zhu, Yinan Zhao, Jian Ge +1
Studying the stellar mass, age, luminosity, star-formation rate, and impact parameter of quasar absorber host galaxies can aid in the understanding of galaxy formation and evolutio…
Quasar 2175 Å dust absorbers II: Correlation analysis and relationship with other absorption line systems
Jingzhe Ma, Jian Ge, J. Xavier Prochaska +6
We present the cold neutral content (H I and C I gas) of 13 quasar 2175 Å dust absorbers (2DAs) at = 1.6 - 2.5 to investigate the correlation between the presence of the UV…
Quasar 2175 Å dust absorbers I: metallicity, depletion pattern, and kinematics
Jingzhe Ma, Jian Ge, Yinan Zhao +4
We present 13 new 2175 Å dust absorbers at z_abs = 1.0 - 2.2 towards background quasars from the Sloan Digital Sky Survey. These absorbers are examined in detail using data from th…
On the Late-Time Spectral Softening Found in X-ray Afterglows of Gamma-Ray Bursts
Yuan-Zhu Wang, Yinan Zhao, Lang Shao +2
Strong spectral softening has been revealed in the late X-ray afterglows of some gamma-ray bursts (GRBs). The scenario of X-ray scattering around circum-burst dusty medium has been…
Identifying the Absorption Bump with Deep Learning
Min Li, Sudeep Gaddam, Xiaolin Li +3
The pervasive interstellar dust grains provide significant insights to understand the formation and evolution of the stars, planetary systems, and the galaxies, and may harbor the…
