The REACH radiometer for detecting the 21-cm hydrogen signal from redshift 7.5 to 28
E. de Lera Acedo, D. I. L. de Villiers, N. Razavi-Ghods +31
Observations of the 21-cm line from primordial hydrogen promise to be one of the best tools to study the early epochs of the Universe: the Dark Ages, the Cosmic Dawn, and the subse…
Lyman- coupling and heating at Cosmic Dawn
Shikhar Mittal, Girish Kulkarni
The global 21-cm signal from the cosmic dawn is affected by a variety of heating and cooling processes. We investigate the impact of heating due to Lyman- (Ly~) photons on th…
Reflection of a Point Object in an Arbitrary Curved Mirror
Shikhar Mittal
In this work, I have derived the equation of the curve obtained on reflection of a point object in an arbitrary curved mirror if the object and the mirror are placed on the 2D Cart…
Path integral Monte Carlo method for the quantum anharmonic oscillator
Shikhar Mittal, Marise J. E. Westbroek, Peter R. King +1
The Markov chain Monte Carlo (MCMC) method is used to evaluate the imaginary-time path integral of a quantum oscillator with a potential that includes both a quadratic term and a q…
