A few examples are given of Chandra’s work on statistical and stochastic problems that relate to open questions in astrophysics, in particular his theory of dynamical relaxation in systems with inverse-square interparticle forces. The roles of chaos and integrability in this theory require clarification, especially for systems having a dominant central mass. After this prelude, a hypothetical form of bosonic dark matter with a simple but nontrivial statistical mechanics is discussed. This makes…

Phenomenological consequences of superfluid dark matter with baryon-phonon coupling
• Physics
Journal of Cosmology and Astroparticle Physics
• 2018
Recently, a new form of dark matter has been suggested to naturally reproduce the empirically successful aspects of Milgrom's law in galaxies. The dark matter particle candidates are axion-like, with
Dynamical friction in superfluids
• Physics

We compute the dynamical friction on a small perturber moving through an inviscid fluid, i.e., a superfluid. Crucially, we account for the tachyonic gravitational mass for sound waves, reminiscent of
Dark Matter Superfluidity
In this talk I summarize a novel framework that unifies the stunning success of MOND on galactic scales with the triumph of the $\Lambda$CDM model on cosmological scales. This is achieved through the
On the mass of ultra-light bosonic dark matter from galactic dynamics
• Physics

We consider the hypothesis that galactic dark matter is composed of ultra-light scalar particles and use internal properties of dwarf spheroidal galaxies to establish a preferred range for the mass m

We propose a novel theory of dark matter (DM) superfluidity that matches the successes of the Λ cold dark matter (ΛCDM) model on cosmological scales while simultaneously reproducing the modified
A brief Review of the Scalar Field Dark Matter model

In the last time the cold dark matter (CDM) model has suggested more and more that it is not able to describe all the properties of nearby galaxies that can be observed in great detail as well as

In these lectures I describe a theory of dark matter superfluidity developed in the last few years. The dark matter particles are axion-like, with masses of order eV. They Bose-Einstein condense into

Observational evidence for self-interacting cold dark matter
• Physics
Physical review letters
• 2000
Astronomical observations may enable us to study dark matter properties that are inaccessible in the laboratory if the cold dark matter particles are self-interacting with a large scattering cross section but negligible annihilation or dissipation.

The gravitational N-body problem is to describe the evolution of an isolated system of N point masses interacting only through Newtonian gravitational forces. For N =2 the solution is due to Newton.

EDDINGTON'S “Internal Constitution of the Stars” was published in 1926 and gives what now ranks as a classical account of his own researches and of the general state of the theory at that time. Since
