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…
Density perturbations in axion-like particles: classical vs quantum field treatment
Sankha Subhra Chakrabarty
Axions and axion-like particles are bosonic quantum fields. They are often assumed to follow classical field equations due to their high degeneracy in the phase space. In this work…
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…
