A Strong Stellar Age-Metallicity Gradient Relation in Nearby Dwarf Galaxies Driven by Stellar Migration and Environmental Quenching
Tie Li, Hong-Xin Zhang, Wenhe Lyu +16
Stellar metallicity gradients () provide a fossil record of the assembly history of galaxies. We present an analysis of for 90 nearby low-mass galaxies u…
The Role of Baryonic and Dark Matter in Bar Kinematics
Tobias Géron, Kai Zhu, Steph Campbell +3
Simulations predict that bars in galaxies should slow down over time. This is often attributed to the exchange of angular momentum between the bar and other regions of the galaxy,…
Unifying the dynamical classification of early-type galaxies: kinematic deficits in IllustrisTNG versus observations
Wenyu Zhong, Min Du, Shengdong Lu +2
We conduct a comparative analysis of galaxy kinematics using IllustrisTNG simulations and integral-field spectroscopy (IFS) observations. We identify 2,342 early-type galaxies (ETG…
Distinguishing the nature of dark matter by mapping cosmic filaments from Lyman-alpha emission
Yizhou Liu, Liang Gao, Shihong Liao +3
The standard CDM cosmological model predicts that cosmic filaments are highly clumpy, whereas warm dark matter -- invoked to address small-scale challenges in CDM -- produces…
