From Starburst to Quenching: Physical Properties of Extremely Compact Starbursts at z0.1

Can Xu, Mengyuan Xiao, Min Bao +5

The compaction phase plays a crucial role in galaxy evolution, as it is strongly linked to star formation activities and structural transformation. We have identified a sample of e…

PANORAMIC: Discovery of an Ultra-Massive Grand-Design Spiral Galaxy at

Mengyuan Xiao, Christina C. Williams, Pascal A. Oesch +26

We report the discovery of an ultra-massive grand-design red spiral galaxy, named Zhúlóng (Torch Dragon), at in the JWST PANORAMIC survey, iden…

A Census of the 200 Most Massive Galaxies Spectroscopically Observed with JWST at zspec 3-15

Mengyuan Xiao, Pascal A. Oesch, Longji Bing +26

Massive galaxies provide strong tests of galaxy formation models, yet a comprehensive spectroscopic view of their properties and demographics in the early Universe has remained elu…

The spatial extension of extended narrow line regions in MaNGA AGN

Jianhang Chen, Yong Shi, Ross Dempsey +10

In this work, we revisit the size-luminosity relation of the extended narrow line regions (ENLRs) using a large sample of nearby active galactic nuclei (AGN) from the Mapping Nearb…

No [CII] or dust detection in two Little Red Dots at z > 7

Mengyuan Xiao, Pascal A. Oesch, Longji Bing +30

Little Red Dots (LRDs) are compact, point-like sources characterized by their red color and broad Balmer lines, which have been debated to be either dominated by active galactic nu…

Host Galaxy Properties of Changing-look AGN Revealed in the MaNGA Survey

Xiaoling Yu, Yong Shi, Yanmei Chen +6

Changing-look Active Galactic Nuclei (CL-AGNs) are a subset of AGNs in which the broad Balmer emission lines appear or disappear within a few years. We use the Mapping Nearby Galax…
