Lower central dark matter densities in nearby galaxies than predicted by simulations
Yu Lei, Ling Zhu, Meng Yang +9
Baryonic feedback in hydrodynamical simulations is typically invoked to alleviate the core--cusp problem in dwarf galaxies. Yet baryonic processes also induce adiabatic contraction…
Mock HUBS observations of hot gas with IllustrisTNG
Yu-Ning Zhang, Chengzhe Li, Dandan Xu +1
The lack of adequate X-ray observing capability is seriously impeding the progress in understanding the hot phase of circumgalactic medium (CGM), which is predicted to extend to th…
Quenched, bulge-dominated, but dynamically cold galaxies in IllustrisTNG and their real-world counterparts
Shengdong Lu, Dandan Xu, Sen Wang +5
Galaxy morphologies, kinematics, and stellar populations are thought to be linked to each other. However, both simulations and observations have pointed out mismatches therein. In…
Stellar Dynamical Modeling - Accuracy of 3D Density Estimation for Edge-on Axisymmetric Galaxies
Richard J. Long, Shengdong Lu, Dandan Xu
From Rybicki's analysis using the Fourier slice theorem, mathematically it is possible to reproduce uniquely an edge-on axisymmetric galaxy's 3D light distribution from its 2D surf…
Hot and counter-rotating star-forming disk galaxies in IllustrisTNG and their real-world counterparts
Shengdong Lu, Dandan Xu, Yunchong Wang +7
A key feature of a large population of low-mass, late-type disk galaxies are star-forming disks with exponential light distributions. They are typically also associated with thin a…
Disentangling the formation history of galaxies via population-orbit superposition: method validation
Ling Zhu, Glenn van de Ven, Ryan Leaman +9
We present population-orbit superposition models for external galaxies based on Schwarzschild's orbit-superposition method, by tagging the orbits with age and metallicity. The mode…
