Non-perturbative non-Gaussianity and primordial black holes
Andrew D. Gow, Hooshyar Assadullahi, Joseph H. P. Jackson +3
We present a non-perturbative method for calculating the abundance of primordial black holes given an arbitrary one-point probability distribution function for the primordial curva…
Observational constraints on interacting vacuum energy with linear interactions
Chakkrit Kaeonikhom, Hooshyar Assadullahi, Jascha Schewtschenko +1
We explore the bounds that can be placed on interactions between cold dark matter and vacuum energy, with equation of state , using state-of-the-art cosmological observations…
Numerical simulations of stochastic inflation using importance sampling
Joseph H. P. Jackson, Hooshyar Assadullahi, Kazuya Koyama +2
We show how importance sampling can be used to reconstruct the statistics of rare cosmological fluctuations in stochastic inflation. We have developed a publicly available package,…
