A gravitational constant transition within cepheids as supernovae calibrators can solve the Hubble tension
Ruchika, Himansh Rathore, Shouvik Roy Choudhury +1
Local universe measurements of the Hubble constant (H0) using SNe Ia with Cepheids as calibrators yield a value of H0 which is in tension with the value inferred from the CMB and o…
A strong broadband 21 cm cosmological signal from dark matter spin-flip interactions
Mansi Dhuria, Viraj Karambelkar, Vikram Rentala +1
In the standard cosmology, it is believed that there are two relatively weak and distinct band-limited absorption features, with the first absorption minima near 20 MHz ()…
On dark matter - dark radiation interaction and cosmic reionization
Subinoy Das, Rajesh Mondal, Vikram Rentala +1
An intriguing possibility for the dark sector of our universe is that the dark matter particle could interact with a dark radiation component. If the non-gravitational interactions…
