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…
The impact of mass map truncation on strong lensing simulations
Lyne Van de Vyvere, Dominique Sluse, Sampath Mukherjee +2
Strong gravitational lensing is a powerful tool to measure cosmological parameters and to study galaxy evolution mechanisms. However, quantitative strong lensing studies often requ…
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…
Early-type galaxy density profiles from IllustrisTNG: II. Evolutionary trend of the total density profile
Yunchong Wang, Mark Vogelsberger, Dandan Xu +8
We study the evolutionary trend of the total density profile of early-type galaxies (ETGs) in IllustrisTNG. To this end, we trace ETGs from to and measure the power-law…
Photometric and Kinematic Misalignments and Their Evolution Among Fast and Slow Rotators in the Illustris Simulation
Lisiyuan Yang, Dandan Xu, Shude Mao +2
We use the Illustris simulation to study the distributions of ellipticities and kinematic misalignments of galactic projections, as well as the intrinsic shapes and rotation of the…
