Obviating PBH overproduction for SIGWs generated by Pulsar Timing Arrays in loop corrected EFT of bounce
Sayantan Choudhury, Siddhant Ganguly, Sudhakar Panda +2
In order to unravel the present situation of the PBH overproduction problem, our study emphasizes the critical role played by the equation of state (EoS) parameter within the f…
Regularized-Renormalized-Resummed loop corrected power spectrum of non-singular bounce with Primordial Black Hole formation
Sayantan Choudhury, Ahaskar Karde, Sudhakar Panda +1
We present a complete and consistent exposition of the regularization, renormalization, and resummation procedures in the setup of having a contraction and then non-singular bounce…
Realisation of the ultra-slow roll phase in Galileon inflation and PBH overproduction
Sayantan Choudhury, Ahaskar Karde, Sudhakar Panda +1
We demonstrate the explicit realisation of the ultra-slow roll phase in the framework of the effective field theory of single-field Galileon inflation. The pulsar timing array (PTA…
Primordial non-Gaussianity as a saviour for PBH overproduction in SIGWs generated by Pulsar Timing Arrays for Galileon inflation
Sayantan Choudhury, Kritartha Dey, Ahaskar Karde +2
We investigate the explicit role of negative local non-Gaussianity, , in suppressing the abundance of primordial black holes (PBHs) in the single-field model of Galileo…
Scalar induced gravity waves from ultra slow-roll Galileon inflation
Sayantan Choudhury, Ahaskar Karde, Sudhakar Panda +1
We consider the production of secondary gravity waves in Galileon inflation with an ultra-slow roll (USR) phase and show that the spectrum of scalar-induced gravitational waves (SI…
Primordial non-Gaussianity from ultra slow-roll Galileon inflation
Sayantan Choudhury, Ahaskar Karde, Sudhakar Panda +1
We present a detailed study of the generation of large primordial non-Gaussianities during the slow-roll (SR) to ultra-slow roll (USR) transitions in the framework of Galileon infl…
