One consistency relation for all single-field inflationary models
Mohammad Hossein Namjoo
In this paper, we present a non-Gaussianity consistency relation that enables the calculation of the squeezed limit bispectrum of the curvature perturbation in single-field inflati…
Beyond Schrödinger-Poisson: Nonrelativistic Effective Field Theory for Scalar Dark Matter
Borna Salehian, Hong-Yi Zhang, Mustafa A. Amin +2
Massive scalar fields provide excellent dark matter candidates, whose dynamics are often explored analytically and numerically using nonrelativistic Schrödinger-Poisson (SP) equati…
Spacetime singularities and a novel formulation of indeterminism
Feraz Azhar, Mohammad Hossein Namjoo
Spacetime singularities in general relativity are commonly thought to be problematic, in that they signal a breakdown in the theory. We address the question of how to interpret thi…
Effective theories for a nonrelativistic field in an expanding universe: Induced self-interaction, pressure, sound speed, and viscosity
Borna Salehian, Mohammad Hossein Namjoo, David I. Kaiser
A massive, nonrelativistic scalar field in an expanding spacetime is usually approximated by a pressureless perfect fluid, which leads to the standard conclusion that such a field…
Enhanced n-body annihilation of dark matter and its indirect signatures
Mohammad Hossein Namjoo, Tracy R. Slatyer, Chih-Liang Wu
We examine the possible indirect signatures of dark matter annihilation processes with a non-standard scaling with the dark matter density, and in particular the case where more th…
Can Light Dark Matter Solve the Core-Cusp Problem?
Heling Deng, Mark P. Hertzberg, Mohammad Hossein Namjoo +1
Recently there has been much interest in light dark matter, especially ultra-light axions, as they may provide a solution to the core-cusp problem at the center of galaxies. Since…
