Disentangling Drivers of Disk Warps in Tilted and Tumbling TNG50 Halos
Saarthak Johri, Neil Ash, Monica Valluri
Dark matter (DM) halos in Cold DM cosmological simulations are triaxial. Most exhibit figure rotation. We study 40 isolated halos with stellar disks from the TNG50 simulation…

Improved particle spray algorithm for modeling globular cluster streams
Yingtian Chen, Monica Valluri, Oleg Y. Gnedin +1
Stellar streams that emerge from globular clusters (GCs) are thin stellar structures spread along the orbits of progenitor clusters. Numerical modeling of these streams is essentia…

Stellar bars form dark matter counterparts in TNG50
Neil Ash, Monica Valluri, Yingtian Chen +1
Dark matter (DM) bars that shadow stellar bars have been previously shown to form in idealized simulations of isolated disk galaxies. Here, we show that DM bars commonly occur in b…
