Studies on the rest frame 21 cm spectral emission line of neutral hydrogen (HI; from the hyperfine spin-flip state transition) provides an interesting and novel way of studying the large-scale structure (LLS), baryon acoustic oscillations (BAO), cosmological models and galaxy dynamics and evolution. By modelling the distribution function of HI within dark matter halos and, consequently, the...
In this work, we will present the preliminary work on statistical detection of kSZ effect using Aperture Photometry. We use DESI cluster galaxy catalogue that follows in Boss-North and D56 ACTPOL region to measure kSZ effect.
In this short presentation, I will discuss about the research work regarding f(R,T) gravity and solutions under various functional form of f(R,T) for Godel universe.
