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…
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…
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…
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…
Dwarf Galaxy Integral-field Survey (DGIS): survey overview and the result of global mass-metallicity relation
Xin Li, Yong Shi, Fuyan Bian +11
Low-mass galaxies are the building blocks of massive galaxies in the framework of hierarchical structure formation. To enable detailed studies of galactic ecosystems in dwarf galax…
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 ($…
MaNGA DynPop -- VI. Matter density slopes from dynamical models of 6000 galaxies versus cosmological simulations: the interplay between baryonic and dark matter
Shubo Li, Ran Li, Kai Zhu +5
We try to understand the trends in the mass density slopes as a function of galaxy properties. We use the results from the best Jeans Anisotropic Modelling (JAM) of the integral-fi…
Quantifying the stellar ages of dynamically separated bulges and disks of CALIFA spiral galaxies
Yunpeng Jin, Ling Zhu, Stefano Zibetti +3
We employ a recently developed population-orbit superposition technique to simultaneously fit the stellar kinematic and age maps of 82 CALIFA spiral galaxies and obtain the ages of…
MaNGA DynPop -- V. The dark-matter fraction versus stellar velocity dispersion relation and stellar initial mass function variations in galaxies: dynamical models and full spectrum fitting of integral-field spectroscopy
Shengdong Lu, Kai Zhu, Michele Cappellari +3
Using the final MaNGA sample of 10K galaxies, we investigate the dark matter fraction within one half-light radius for about 6K galaxies with good kinemati…
MaNGA DynPop -- III. Stellar dynamics versus stellar population relations in 6000 early-type and spiral galaxies: Fundamental Plane, mass-to-light ratios, total density slopes, and dark matter fractions
Kai Zhu, Shengdong Lu, Michele Cappellari +4
We present dynamical scaling relations, combined with the stellar population properties, for a subsample of about 6000 nearby galaxies with the most reliable dynamical models extra…
