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…

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…
