Dissecting the 3D chemo-dynamical structures of NGC 1381: a galaxy hosting an ancient slow bar with an accreted bulge and thick disc
Yunpeng Jin, Ling Zhu, Shude Mao +4
We applied the barred population-orbit superposition method developed in \citet{Jin2025a,Jin2025b} to construct 3D chemo-dynamical models for the barred S0 galaxy NGC~1381 in the F…
Gravitational lensing by a spiral galaxy I: the influence from bar's structure to the flux ratio anomaly
Xikai Shan, Yunpeng Jin, Shude Mao
Gravitational lens flux ratio anomalies are a powerful probe of small-scale mass structures, often attributed to dark matter subhalos. However, baryonic components can also play a…
Orbit-based structural decomposition and stellar population recovery for edge-on barred galaxies
Yunpeng Jin, Ling Zhu, Behzad Tahmasebzadeh +3
In our previous paper, we developed an orbit-superposition method for edge-on barred galaxies and constructed a set of dynamical models based on different mock observations of thre…
Unifying the dynamical classification of early-type galaxies: kinematic deficits in IllustrisTNG versus observations
Wenyu Zhong, Min Du, Shengdong Lu +2
We conduct a comparative analysis of galaxy kinematics using IllustrisTNG simulations and integral-field spectroscopy (IFS) observations. We identify 2,342 early-type galaxies (ETG…
Recovering the pattern speeds of edge-on barred galaxies via an orbit-superposition method
Yunpeng Jin, Ling Zhu, Behzad Tahmasebzadeh +4
We developed an orbit-superposition method for edge-on barred galaxies and evaluated its capability to recover the bar pattern speed . We selected three simulated galaxies…
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…
