A quiescent galaxy in a gas-rich cosmic web node at z~3
Weichen Wang, Sebastiano Cantalupo, Marta Galbiati +11
Recent JWST observations have unveiled a large number of quiescent galaxies at , bringing potential challenges to current galaxy formation models. Since star formation i…
A massive barred spiral galaxy at z = 5.102 discovered by JWST
Xiaohan Wang, Fengwu Sun, Yoshihisa Asada +21
We report M1149-BSG-z5, a barred spiral galaxy at , identified in the parallel field of MACS J1149+2223 with JWST and HST. M1149-BSG-z5 is the highest redshift barred ga…
Metal enrichment of galaxies in a massive node of the Cosmic Web at
Xiaohan Wang, S. Cantalupo, Weichen Wang +8
We present the mass-metallicity relation for star-forming galaxies in the MUSE Quasar Nebula 01 (MQN01) field, a massive cosmic web node at , hosting one of the large…
MaNGA DynPop. VII. A Unified Bulge-Disk-Halo Model for Explaining Diversity in Circular Velocity Curves of 6000 Spiral and Early-Type Galaxies
Kai Zhu, Michele Cappellari, Shude Mao +6
We derive circular velocity curves (CVCs) from stellar dynamical models for nearby galaxies in the final data release of the Sloan Digital Sky Survey-IV MaNGA survey wit…
SDSS-IV MaNGA: Stellar rotational support in disk galaxies vs. central surface density and stellar population age
Xiaohan Wang, Yifei Luo, S. M. Faber +10
We investigate how the stellar rotational support changes as a function of spatially resolved stellar population age () and relative central stellar surface density ($…
