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…
