Constraining the parameters of an isolated neutron star using the lensed HI signal at uGMRT
Rupa Basu, Siddhartha Bhattacharyya, Anjan Kumar Sarkar +2
The strength of the HI signal originating from a distant galaxy at a cosmological distance is several orders of magnitude lower than the foreground and background noise and hence i…
Thermal Evolution of the IGM due to Lyman-α photons during the Cosmic Dawn
Janakee Raste, Anjan Kumar Sarkar, Shiv K. Sethi
The first star-forming objects which formed at high redshifts during the cosmic dawn (CD) also emitted photons between Lyman- and Lyman-limit frequencies. These photons are inst…
Constraining ultra slow roll inflation using cosmological datasets
H. V. Ragavendra, Anjan Kumar Sarkar, Shiv K. Sethi
In recent years, the detection of gravitational waves by LIGO and PTA collaborations have raised the intriguing possibility of excess matter power at small scales. Such an increase…
