PIANISTpy: A JAX-based Python package for velocity-anisotropic astrophysical equilibrium models

Barry T. Chiang, Frank C. van den Bosch, Hsi-Yu Schive

The hierarchical assembly of dark matter haloes and galaxies via mergers and anisotropic mass accretion naturally imprints non-trivial velocity anisotropy onto haloes and galaxies,…

Scatter, bias, and chaos of satellite orbits in triaxial dark matter haloes

Barry T. Chiang, Frank C. van den Bosch, Michael A. Keim

The pericentric distances of satellite galaxies govern their tidal stripping, quenching, and survival, yet their orbits are almost universally computed in spherical host haloes, wh…

Statistical Properties of Cold Streams In Massive Star-Forming Halos in TNG50

Isabel Medlock, Daisuke Nagai, Nir Mandelker +4

Cold, dense streams of gas are predicted to penetrate deeply into massive halos (> 10^12 Msun) at cosmic noon (z=4-2), fueling galaxies to sustain high star formation rates. We inv…

The tidal evolution of anisotropic subhaloes: A new pathway to creating isotropic and cored satellites

Barry T. Chiang, Frank C. van den Bosch, Hsi-Yu Schive

It is common practice, both in dynamical modelling and in idealised numerical simulations, to assume that galaxies and/or dark matter haloes are spherical and have isotropic veloci…

Galactic disc heating by density granulation in fuzzy dark matter simulations

Hsun-Yeong Yang, Barry T. Chiang, Guan-Ming Su +3

Fuzzy dark matter (FDM), an attractive dark matter candidate comprising ultralight bosons (axions) with a particle mass eV, is motivated by the small-scale challe…

Can ultralight dark matter explain the age-velocity dispersion relation of the Milky Way disc: A revised and improved treatment

Barry T. Chiang, Jeremiah P. Ostriker, Hsi-Yu Schive

Ultralight axion-like particles eV, or Fuzzy Dark Matter (FDM), behave comparably to cold dark matter (CDM) on cosmological scales and exhibit a kpc-size de Bro…
