Probing the shape of the Milky Way dark matter halo with hypervelocity stars: a new method
Arianna Gallo, Luisa Ostorero, Sankha Subhra Chakrabarty +2
We propose a new method to determine the shape of the gravitational potential of the dark matter (DM) halo of the Milky Way (MW) with the galactocentric tangential velocities of a…
Probing modified Newtonian dynamics with hypervelocity stars
Sankha Subhra Chakrabarty, Luisa Ostorero, Arianna Gallo +2
We show that measuring the velocity components of hypervelocity stars (HVSs) can discriminate between modified Newtonian dynamics (MOND) and Newtonian gravity. HVSs are ejected fro…
Implications of triangular features in the Gaia skymap for the Caustic Ring Model of the Milky Way halo
Sankha S. Chakrabarty, Yaqi Han, Anthony H. Gonzalez +1
The Gaia map of the Milky Way reveals a pair of triangular features at nearly symmetric locations on opposite sides of the Galactic Center. In this paper we explore the implication…
Effects of a caustic ring of dark matter on the distribution of stars and interstellar gas
Sankha S. Chakrabarty, Pierre Sikivie
Caustic rings of dark matter with cross-section were predicted to lie in the galactic disk. Their radii increase on cosmological time scales at a rate of order $…
