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…
Orbit-based structural decomposition and stellar population recovery for edge-on barred galaxies
Yunpeng Jin, Ling Zhu, Behzad Tahmasebzadeh +3
In our previous paper, we developed an orbit-superposition method for edge-on barred galaxies and constructed a set of dynamical models based on different mock observations of thre…
Dynamical Modelling of Galactic Kinematics using Neural Networks
David A. Simon, Michele Cappellari, Shude Mao +2
The advent of integral field data has revolutionised the study of galaxy evolution. A key component of this is dynamical modelling methods which have allowed for crucial insights t…
Searching for Galaxy Cluster-Scale Strong lenses from the DESI Legacy Imaging Surveys
Zhejian Zhang, Nan Li, Shude Mao +4
Galaxy cluster-scale strong gravitational lensing systems are rare yet valuable tools for investigating the properties of dark matter and dark energy, as well as providing the oppo…
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…
