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
The authors model the stochastic gravitational-wave background from metastable cosmic strings and simulate LISA observations with instrumental noise and astrophysical foregrounds.…
Mapping Domain-Wall Bayesian Reconstruction with LISA
Satyabrata Datta, Rome Samanta
We study the Bayesian reconstruction of peaked domain-wall gravitational-wave signals at LISA and construct reconstruction maps over the signal-parameter plane. These maps identify…
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…
Gravitational Wave Spectral Shapes as a probe of Long Lived Right-handed Neutrinos, Leptogenesis and Dark Matter: Global versus Local B-L Cosmic Strings
Satyabrata Datta, Anish Ghoshal, Angus Spalding +1
The scale of the seesaw mechanism is typically much larger than the electroweak scale. This hierarchy can be naturally explained by symmetry, which after spontaneous s…
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…
