Searching for Type Ia Supernovae in the Dark Energy Spectroscopic Instrument
Xiaoyu Zhuang, Song Ran, Dezheng Meng +9
With the development of large-scale photometric surveys, an increasing number of supernova candidates are being discovered, leading to a rapidly growing demand for supernova spectr…
Theoretical emission lines and metallicity calibrations of H II regions in ASTRID simulation
Yao Yao, Kathryn Grasha, Stuart Wyithe +5
We present a theoretical framework to derive redshift-dependent metallicity calibrations for galaxies at =2-7. The ionization parameter () and gas pressure () in our appro…
Updated Metallicity Diagnostics for Precision Oxygen Abundance Measurements in High-redshift Galaxies with JWST
Shihong Liu, Yu Rong, Tie Li +7
Recent work has demonstrated that widely used strong-line oxygen abundance indicators, such as O3N2, , and , suffer from large uncertainties when applied…
The Internal Kinematics, Stellar Population, and Gas-phase Properties of The Pseudobulge in An Ultra-diffuse Galaxy: AGC721966
Shihong Liu, Yu Rong, Huiyuan Wang +8
Leveraging spectroscopic data from the Sloan Digital Sky Survey, we conduct a comprehensive analysis of the central stellar velocity dispersion, stellar population properties, star…
A negative stellar massgaseous metallicity gradient relation of dwarf galaxies modulated by stellar feedback
Tie Li, Hong-Xin Zhang, Wenhe Lyu +16
Baryonic cycling is reflected in the spatial distribution of metallicity within galaxies, yet gas-phase metallicity distribution and its connection with other properties of dwarf g…
Size Growth on Short Timescales of Star-Forming Galaxies: Insights from Size Variation with Rest-Frame Wavelength with JADES
Cheng Jia, Enci Wang, Huiyuan Wang +11
We investigate size variation with rest-frame wavelength for star-forming galaxies based on the second JWST Advanced Deep Extragalactic Survey data release. Star-forming galaxies a…
The circumgalactic medium traced by Mg II absorption with DESI: dependence on galaxy stellar mass, star formation rate and azimuthal angle
Zeyu Chen, Enci Wang, Hu Zou +10
Understanding the circumgalactic medium (CGM) distribution of galaxies is the key to revealing the dynamical exchange of materials between galaxies and their surroundings. In this…
Bipolar blobs as evidence of hidden AGN activities in the low-mass galaxies
Yao Yao, Enci Wang, Zhicheng He +4
We report the evidence of a hidden black hole (BH) in a low-mass galaxy, MaNGA 9885-9102, and provide a new method to identify active BH in low mass galaxies. This galaxy is origin…
USmorph: An Updated Framework of Automatic Classification of Galaxy Morphologies and Its Application to Galaxies in the COSMOS Field
Jie Song, GuanWen Fang, Shuo Ba +9
Morphological classification conveys abundant information on the formation, evolution, and environment of galaxies. In this work, we refine the two-step galaxy morphological classi…
Strong [O III] λ5007 Compact Galaxies Identified from SDSS DR16 and Their Scaling Relations
Weiyu Ding, Hu Zou, Xu Kong +11
Green pea galaxies are a special class of star-forming compact galaxies with strong [O III]λ5007 and considered as analogs of high-redshift Lyα-emitting galaxies and potential sour…
Evolution of Non-parametric Morphology of Galaxies in the JWST CEERS Field at 0.8-3.0
Yao Yao, Jie Song, Xu Kong +3
Galaxy morphology is one of the most fundamental ways to describe galaxy properties, but the morphology we observe may be affected by wavelength and spatial resolution, which may i…
