A New Probe of the Distribution of Dark Matter in Galaxies
Sukanya Chakrabarti
The scale radius of dark matter halos is a critical parameter for specifying the density distribution of dark matter, and is therefore a fundamental parameter for modeling galaxies…
The Sagittarius impact as an architect of spirality and outer rings in the Milky Way
Chris W. Purcell, James S. Bullock, Erik Tollerud +2
Like many galaxies of its size, the Milky Way is a disk with prominent spiral arms rooted in a central bar, although our knowledge of its structure and origin is incomplete. Tradit…
Dark Subhaloes and Disturbances in Extended HI Discs
Philip Chang, Sukanya Chakrabarti
We develop a perturbative approach to study the excitation of disturbances in the extended atomic hydrogen (HI) discs of galaxies produced by passing dark matter subhaloes. The sha…
Finding Dwarf Galaxies From Their Tidal Imprints
Sukanya Chakrabarti, Frank Bigiel, Philip Chang +1
We describe ongoing work on a new method that allows one to determine the mass and relative position (in galactocentric radius and azimuth) of galactic companions purely from analy…
