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…
High-Quality Axion Dark Matter at Gravitational Wave Interferometers
Disha Bandyopadhyay, Debasish Borah, Nayan Das +1
Gravitational effects are known to violate global symmetries, threatening the Peccei-Quinn (PQ) solution to the strong CP problem. Ultraviolet completions featuring a gauged …
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…
