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…
Accreted Globular Clusters in External Galaxies: Why Adaptive Dynamics is not the Solution
Sophia Lilleengen, Wilma H. Trick, Glenn van de Ven
Many astrophysical and galaxy-scale cosmological problems require a well determined gravitational potential which is often modeled by observers under strong assumptions. Globular c…
Survival of molecular gas in a stellar feedback-driven outflow witnessed with the MUSE TIMER project and ALMA
Ryan Leaman, Francesca Fragkoudi, Miguel Querejeta +15
Stellar feedback plays a significant role in modulating star formation, redistributing metals, and shaping the baryonic and dark structure of galaxies -- however, the efficiency of…
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…
The Fornax Deep Survey with VST. VII. Evolution and Structure of Late Type Galaxies inside the Virial Radius of the Fornax Cluster
M. A. Raj, E. Iodice, N. R. Napolitano +15
We present the study of a magnitude limited sample (mB < 16.6 mag) of 13 late type galaxies (LTGs), observed inside the virial radius, Rvir 0.7 Mpc, of the Fornax cluster within th…
Insights into formation scenarios of massive Early-Type galaxies from spatially resolved stellar population analysis in CALIFA
Stefano Zibetti, Anna R. Gallazzi, Michaela Hirschmann +4
We perform spatially resolved stellar population analysis for a sample of 69 early-type galaxies (ETGs) from the CALIFA integral field spectroscopic survey, including 48 elliptical…
Star formation quenching imprinted on the internal structure of naked red nuggets
Ignacio Martín-Navarro, Glenn van de Ven, Akın Yıldırım
The formation and assembly process of massive galaxies is a combination of two phases: an initial in-situ-dominated one followed by an ex-situ-dominated evolution. Separating these…
A metal-poor ultra compact dwarf galaxy at a kiloparsec distance from the low-mass elliptical galaxy FCC47
Katja Fahrion, Iskren Georgiev, Michael Hilker +7
Photometric surveys of galaxy clusters have revealed a large number of ultra compact dwarfs (UCDs) around predominantly massive elliptical galaxies. Their origin is still debated a…
A galaxy's accretion history unveiled from its integrated spectrum
Alina Boecker, Ryan Leaman, Glenn van de Ven +3
We present a new method of quantifying a galaxy's accretion history from its integrated spectrum alone. Using full spectral fitting and calibrated regularization techniques we show…
