New astrophysical bounds on ultralight axionlike particles
Nilanjan Banik, Adam J. Christopherson, Pierre Sikivie +1
Motivated by tension between the predictions of ordinary cold dark matter (CDM) and observations at galactic scales, ultralight axionlike particles (ULALPs) with mass of the order…
The Rethermalizing Bose-Einstein Condensate of Dark Matter Axions
Nilanjan Banik, Adam Christopherson, Pierre Sikivie +1
The axions produced during the QCD phase transition by vacuum realignment, string decay and domain wall decay thermalize as a result of their gravitational self-interactions when t…
Linear Newtonian perturbation theory from the Schrödinger-Poisson equations
Nilanjan Banik, Adam J. Christopherson, Pierre Sikivie +1
We obtain solutions to the coupled Schrödinger-Poisson equations. The solutions describe the evolution of cold dark matter density perturbations in an otherwise homogeneous expandi…
