Bayesian Forecasts on Cosmic Superstring Searches with LISA
Satyabrata Datta, Rome Samanta
Cosmic superstrings are well-motivated early-Universe sources of stochastic gravitational waves, with phenomenology controlled by the string tension and the intercommutation p…
LISA Reconstruction Landscape for Metastable Cosmic Strings
Satyabrata Datta, Rome Samanta
We study reconstruction of stochastic gravitational-wave backgrounds from metastable cosmic strings with the Laser Interferometer Space Antenna (LISA). In the vacuum-tunneling benc…
PTA-Compatible Domain Walls at LISA and Taiji: Bayesian Reconstruction and Multiband Inference
Satyabrata Datta, Rome Samanta
Domain walls provide an excellent fit to Pulsar Timing Array (PTA) data. A distinctive feature of the associated gravitational-wave (GW) spectrum is its ultraviolet (UV) tail, whic…
Probing thermal leptogenesis and dark matter through primordial gravitational waves from a supercooled universe
Peter Athron, Satyabrata Datta, Zhao-Yang Zhang
We explore the cosmological dynamics of a supercooled first-order phase transition in the classically conformal extension of the Standard Model, where radiative symmet…
Multifaceted Supercooling: From PTA to LIGO
Satyabrata Datta, Rome Samanta
Supercooled phase transitions, as predicted, e.g., in near-conformal and confining extensions of the Standard Model (SM), are established sources of strong stochastic gravitational…
Complementarity between Cosmic String Gravitational Waves and long-lived particle searches in a laboratory
Satyabrata Datta, Ambar Ghosal, Anish Ghoshal +1
Cosmic strings are powerful witnesses to cosmic events including any period of early matter domination. If such a period of matter domination was catalysed by metastable, long-live…
