CSST Preparations: Galaxy Completeness and Sérsic Profile Fitting across the Wide, Deep, and Extreme Fields
Ziqi Ma, Si-Yue Yu, Taotao Fang +3
The upcoming imaging survey of the Chinese Space-station Survey Telescope (CSST) will deliver high-resolution imaging of an unprecedented number of galaxies for galaxy studies. To…
COSMOS-3D: Black Hole Mass Estimators and Luminosity Functions of Paschen-line AGNs
Danyang Jiang, Linhua Jiang, Shuqi Fu +13
Near-IR Paschen lines are potentially an excellent tracer of Type 1 AGNs that is hardly affected by dust extinction. JWST allows us, for the first time, to explore Paschen-line obj…
Through Thick and Thin: The Cosmic Evolution of Disk Scale Height
Si-Yue Yu, Luis C. Ho, Takafumi Tsukui +16
To investigate the formation and evolution of vertical structures in disk galaxies, we measure global scale heights, averaging thin and thick components whe…
Galactic bars are already mature at Cosmic Noon: bar strength and flatness at z ~ 1.5
Boris S. Kalita, Luis C. Ho, John D. Silverman +6
In this work, we explore the nature of galactic bars. Once thought to be highly transient, our results demonstrate otherwise. Our sample consists of nine massive ($>10^{10.5}…
A multi-wavelength investigation of spiral structures in galaxies with JWST
Boris S. Kalita, Si-Yue Yu, John D. Silverman +18
Recent JWST observations have revealed the prevalence of spiral structures at . Unlike in the local Universe, the origin and the consequence of spirals at this epoch remain…
