The effect of environment on the properties of the most massive galaxies at in the cosmos-dash field

Jie Song, Guanwen Fang, Yizhou Gu +2

How the environment influences the most massive galaxies is still unclear. To explore the environmental effects on morphology and star formation in the most massive galaxies at hig…

Ly imaging around the hyperluminous dust-obscured quasar W22460526 at

Yibin Luo, Lulu Fan, Yongming Liang +10

Hot dust-obscured galaxies (Hot DOGs) are a population of hyperluminous, heavily obscured quasars discovered by the \emph{Wide-field Infrared Survey Explorer} (\emph{WISE}) all-sky…

The ISM scaling relations using inner HI and an application of estimating dust mass

Fujia Li, Jing Wang, Fengwei Xu +4

We select a disk-like galaxy sample with observations of the , and dust from Herschel Reference Survey (HRS), and derive inner HI masses within the optical radius. We f…

Solution to the conflict between the resolved and unresolved galaxy stellar mass estimation from the perspective of JWST

Jie Song, GuanWen Fang, Zesen Lin +2

By utilizing the spatially-resolved photometry of galaxies at in the CEERS field, we estimate the resolved and unresolved stellar mass via spectral energy distribution…

An efficient unsupervised classification model for galaxy morphology: Voting clustering based on coding from ConvNeXt large model

Guanwen Fang, Yao Dai, Zesen Lin +6

In this work, we update the unsupervised machine learning (UML) step by proposing an algorithm based on ConvNeXt large model coding to improve the efficiency of unlabeled galaxy mo…

Spectroscopic Observation and Analysis of HII regions in M33 with MMT: Temperatures and Oxygen Abundances

Zesen Lin, Ning Hu, Xu Kong +7

The spectra of 413 star-forming (or HII) regions in M33 (NGC 598) were observed by using the multifiber spectrograph of Hectospec at the 6.5-m Multiple Mirror Telescope (MMT). By u…
