Conventional galaxy mass estimation methods suffer from model assumptions and
degeneracies. Machine learning (ML), which reduces the reliance on such assumptions, can …

Almost two-thirds of disk galaxies in the local universe host bars, which serve as important
drivers of secular evolutionary processes. While cosmological simulations are powerful tools …

Large galaxy samples from multiobject integral field spectroscopic (IFS) surveys now allow
for a statistical analysis of the z∼ 0 galaxy population using resolved kinematic …

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 …

We recently developed an automated method, auto-GMM, to decompose simulated
galaxies. It extracts kinematic structures in an accurate, efficient, and unsupervised way. We …

Galactic dynamical structures are fossil records of the assembly histories of galaxies. By
analyzing the cosmological hydrodynamical simulation TNG50, we find that a dynamical …

The flat stellar density cores of massive elliptical galaxies form rapidly due to sinking
supermassive black holes (SMBHs) in gas-poor galaxy mergers. After the SMBHs form a …

We analyse VLT/MUSE observations of PGC 046832, the brightest cluster galaxy of Abell
3556. The velocity structure of this galaxy is startling and shows two reversals in sign along …

We study black hole–host galaxy correlations, and the relation between the
overmassiveness (the distance from the average M BH–σ relation) of supermassive black …

The gas needed to sustain star formation in galaxies is supplied by the circumgalactic
medium (CGM), which in turn is affected by accretion from large scales. In a series of two …
