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…
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…
Probing Leptogenesis at LISA: A Fisher analysis
Rome Samanta
In JCAP 11 (2024) 051, we discussed how different regimes (flavoured) of leptogenesis can be probed through a ``tomographic'' approach using primordial gravitational waves. By exam…
