SDSS-IV MaNGA: Internal mass distributions and orbital structures of early-type galaxies and their dependence on environment
Yunpeng Jin, Ling Zhu, R. J. Long +3
In our earlier 2019 paper, we evaluated the reliability of Schwarzschild's orbit-superposition dynamical modelling method in estimating the internal mass distribution, intrinsic st…
Mapping the dark matter halo of early-type galaxy NGC 2974 through orbit-based models with combined stellar and cold gas kinematics
Meng Yang, Ling Zhu, Anne-Marie Weijmans +4
We present an orbit-based method of combining stellar and cold gas kinematics to constrain the dark matter profile of early-type galaxies. We apply this method to early-type galaxy…
NGC 7457: Evidence for merger-driven cylindrical rotation in disc galaxies
Alireza Molaeinezhad, Ling Zhu, Jesús Falcón-Barroso +7
We construct Schwarzschild orbit-based models of NGC 7457, known as a peculiar low-mass lenticular galaxy. Our best-fitting model successfully retrieves most of the unusual kinemat…
Constraining nuclear star cluster formation using MUSE-AO observations of the early-type galaxy FCC47
Katja Fahrion, Mariya Lyubenova, Glenn van de Ven +12
Nuclear star clusters (NSCs) are found in at least 70% of all galaxies, but their formation path is still unclear. In the most common scenarios, NSCs form in-situ from the galaxy's…
A study of stellar orbit fractions: simulated IllustrisTNG galaxies compared to CALIFA observations
Dandan Xu, Ling Zhu, Robert Grand +16
Motivated by the recently discovered kinematic "Hubble sequence" shown by the stellar orbit-circularity distribution of 260 CALIFA galaxies, we make use of a comparable galaxy samp…
Evaluating the ability of triaxial Schwarzschild modelling to estimate properties of galaxies from the Illustris simulation
Yunpeng Jin, Ling Zhu, R. J. Long +4
We evaluate the capabilities of Schwarzschild's orbit-superposition method by applying it to galaxies from the large scale, high resolution Illustris simulation. Nine early-type ga…
Combining Stellar Populations with Orbit-Superposition Dynamical Modelling - the Formation History of the Lenticular Galaxy NGC 3115
Adriano Poci, Richard M. McDermid, Ling Zhu +1
We present a combination of the Schwarzschild orbit-superposition dynamical modelling technique with the spatially-resolved mean stellar age and metallicity maps to uncover the for…
