Kinematical coherence between satellite galaxies and host stellar discs for MaNGA & SAMI galaxies
Sen Wang, Dandan Xu, Shengdong Lu +1
The effect of angular momentum on galaxy formation and evolution has been studied for several decades. Our recent two papers using IllustrisTNG-100 simulation have revealed the acq…
Galaxy stellar and total mass estimation using machine learning
Jiani Chu, Hongming Tang, Dandan Xu +2
Conventional galaxy mass estimation methods suffer from model assumptions and degeneracies. Machine learning, which reduces the reliance on such assumptions, can be used to determi…
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…
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…
Velocity Dispersion Aperture Corrections as a Function of Galaxy Properties from Integral-field Stellar Kinematics of 10,000 MaNGA Galaxies
Kai Zhu, Ran Li, Xiaoyue Cao +3
The second moment of the stellar velocity within the effective radius, denoted by , is a crucial quantity in galaxy studies as it provides insight into galaxy properti…
A complete catalogue of broad-line AGNs and double-peaked emission lines from MaNGA integral-field spectroscopy of 10K galaxies: stellar population of AGNs, supermassive black holes, and dual AGNs
Youquan Fu, Michele Cappellari, Shude Mao +3
We analyse the integral-field spectroscopy data for the galaxies in final data release of the MaNGA survey. We identify 188 galaxies for which the emission lines ca…
MaNGA DynPop -- IV. Stacked total density profile of galaxy groups and clusters from combining dynamical models of integral-field stellar kinematics and galaxy-galaxy lensing
Chunxiang Wang, Ran Li, Kai Zhu +9
We present the measurement of total and stellar/dark matter decomposed mass density profile around a sample of galaxy groups and clusters with dynamical masses derived from integra…
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…
MaNGA DynPop -- II. Global stellar population, gradients, and star-formation histories from integral-field spectroscopy of 10K galaxies: link with galaxy rotation, shape, and total-density gradients
Shengdong Lu, Kai Zhu, Michele Cappellari +3
This is the second paper of the MaNGA DynPop series, which analyzes the global stellar population, radial gradients, and non-parametric star-formation history of K galaxie…
MaNGA DynPop -- I. Quality-assessed stellar dynamical modelling from integral-field spectroscopy of 10K nearby galaxies: a catalogue of masses, mass-to-light ratios, density profiles and dark matter
Kai Zhu, Shengdong Lu, Michele Cappellari +3
This is the first paper in our series on the combined analysis of the Dynamics and stellar Population (DynPop) for the MaNGA survey in the final SDSS Data Release 17 (DR17). Here w…
