Comparison of numerical methods for computing the repeated Compton scattering of photons in isotropic media
Sandeep Kumar Acharya, Jens Chluba, Abir Sarkar
Repeated Compton scattering of photons with thermal electrons is one of the fundamental processes at work in many astrophysical plasma. Solving the exact evolution equations is har…
Dissecting the Compton scattering kernel I: Isotropic media
Abir Sarkar, Jens Chluba, Elizabeth Lee
Compton scattering between electrons and photons plays a crucial role in astrophysical plasmas. Many important aspects of this process can be captured by using the so-called Compto…
The effects of the small-scale behaviour of dark matter power spectrum on CMB spectral distortion
Abir Sarkar, Shiv K. Sethi, Subinoy Das
After numerous astronomical and experimental searches, the precise particle nature of dark matter is still unknown. The standard Weakly Interacting Massive Particle(WIMP) dark matt…
How Late can the Dark Matter form in our universe?
Abir Sarkar, Subinoy Das, Shiv K. Sethi
We put constraints on the epoch of dark matter formation for a class of non-WIMP (Weakly Interacting Massive Particle) dark matter candidates. These models allow a fraction of Cold…
