Mock member stars for 28 dwarf galaxies are constructed from the cosmological auriga simulation, which reflects the dynamical status of realistic stellar tracers. Axisymmetric Jeans Anisotropic Multi-Gaussian Expansion (jam) modeling is applied to 60... Read More about Is the Core-cusp Problem a Matter of Perspective?

What to expect from dynamical modelling of galactic haloes (2017)
Journal Article
Wang, W., Han, J., Cole, S., Frenk, C., & Sawala, T. (2017). What to expect from dynamical modelling of galactic haloes. Monthly Notices of the Royal Astronomical Society, 470(2), 2351-2366. https://doi.org/10.1093/mnras/stx1334

Many dynamical models of the Milky Way halo require assumptions that the distribution function of a tracer population should be independent of time (i.e. a steady-state distribution function) and that the underlying potential is spherical. We study t... Read More about What to expect from dynamical modelling of galactic haloes.

Aims. We aim to study the 250 μm luminosity function (LF) down to much fainter luminosities than achieved by previous efforts. Methods. We developed a modified stacking method to reconstruct the 250 μm LF using optically selected galaxies from the SD... Read More about The faint end of the 250 μm luminosity function at z < 0.5.

Monthly Notices of the Royal Astronomical Society, 456(3), 2301-2320. https://doi.org/10.1093/mnras/stv2809

We use weak gravitational lensing to measure mean mass profiles around locally brightest galaxies (LBGs). These are selected from the Seventh Data Release of the Sloan Digital Sky Survey spectroscopic and photometric catalogues to be brighter than an...

We develop two general methods to infer the gravitational potential of a system using steady-state tracers, i.e. tracers with a time-independent phase-space distribution. Combined with the phase-space continuity equation, the time independence implie... Read More about The orbital PDF: general inference of the gravitational potential from steady-state tracers.
