Fingerprint of GeV scale right-handed neutrinos on inflationary gravitational waves and PTA data
Satyabrata Datta, Rome Samanta
We show that the seesaw mechanisms that exhibit right-handed neutrino mass-dependent non-standard post-inflationary cosmology make blue-tilted inflationary gravitational waves (GW)…
Imprint of inflationary gravitational waves and WIMP dark matter in pulsar timing array data
Debasish Borah, Suruj Jyoti Das, Rome Samanta
Motivated by the recent release of new results from five different pulsar timing array (PTA) experiments claiming to have found compelling evidence for primordial gravitational wav…
Imprint of PBH domination on gravitational waves generated by cosmic strings
Debasish Borah, Suruj Jyoti Das, Rishav Roshan +1
We study the effect of an ultra-light primordial black hole (PBH) dominated phase on the gravitational wave (GW) spectrum generated by a cosmic string (CS) network formed as a resu…
Shimmering gravitons in the gamma-ray sky
Sabir Ramazanov, Rome Samanta, Georg Trenkler +1
What is the highest energy at which gravitons can be observed? We address this question by studying graviton-to-photon conversion - the inverse-Gertsenshtein effect - in the magnet…
