CatNorth: An Improved Gaia DR3 Quasar Candidate Catalog with Pan-STARRS1 and CatWISE
The Astrophysical Journal Supplement SeriesA complete and pure sample of quasars with accurate redshifts is crucial for quasar studies and cosmology. In this paper, we present CatNorth, an improved Gaia Data Release 3 (Gaia DR3) quasar candidate catalog with more than 1.5 million sources in the 3

Different Planetary Eccentricity-period (PEP) Distributions of Small and Giant Planets
The Astronomical JournalWe used the database of 1040 short-period (1 ≤ P < 200 days) exoplanets radial-velocity orbits to study the planetary eccentricity-period (PEP) distribution.

Singular Spectrum Analysis of Exoplanetary Transits
The Astronomical JournalTransit photometry is currently the most efficient and sensitive method for detecting extrasolar planets (exoplanets) and a large majority of confirmed exoplanets have been detected with this method.

GRB Progenitor Classification from Gamma-Ray Burst Prompt and Afterglow Observations
The Astrophysical JournalUsing an established classification technique, we leverage standard observations and analyses to predict the progenitors of gamma-ray bursts (GRBs). This technique, utilizing support vector machine statistics, provides a more nuanced prediction than the ...

Galaxy and Mass Assembly (GAMA): Stellar-to-dynamical Mass Relation. II. Peculiar Velocities
The Astrophysical JournalEmpirical correlations connecting starlight to galaxy dynamics (e.g., the fundamental plane (FP) of elliptical/quiescent (Q) galaxies and the Tully–Fisher relation of spiral/star-forming (SF) galaxies) provide cosmology-independent distance estimation ...

Diffusion-based Galaxy Simulations for the Nancy Grace Roman Space Telescope High Latitude Survey
The Astrophysical JournalFuture weak lensing analyses with the Nancy Grace Roman Space Telescope (Roman) will require highly realistic image simulations to control shear systematics at unprecedented precision. A key limitation of existing approaches is their reliance on analytic
