CMB Injection Bounds on Moduli Fields
Naman Agarwal, Andrew R. Frey, Ratul Mahanta +3
Light scalar fields with gravitational strength interactions (moduli) are ubiquitous in string, supergravity, and extra-dimensional models. If produced in the early universe with l…
Transient Early Dark Energy-Like Dynamics as a Mechanism for Enhanced Early Structure Formation in the JWST Era
Abhik Bhattacharjee, Amlan Chakraborty, Subinoy Das +2
The discovery of massive galaxies at redshifts by the James Webb Space Telescope (JWST) has renewed interest in cosmological mechanisms capable of enhancing early stru…
Dark Monopoles, Bounds on Hidden Sectors, and Cosmological Implications
Donald Liveoak, Anshuman Maharana, James D. Wells
Hidden sectors are a generic prediction of string theory compactifications and result in a promising landscape for dark matter model building. We consider the case of hidden sector…
Flux Vacua Near the Boundary of Large Complex Structure
Aman Chauhan, Michele Cicoli, Anshuman Maharana +1
Three-form fluxes generate a potential for the complex structure moduli in type IIB string compactifications on Calabi-Yau threefolds. In the large complex structure patch, the pot…
Parameter compression in the flux landscape
Aman Chauhan, Michele Cicoli, Sven Krippendorf +3
We present a data-driven investigation of the exhaustive ensemble of no-scale type IIB flux vacua constructed in \cite{Chauhan:2025rdj}. Using a combination of linear and non-linea…
Forecasting Constraints on Non-Thermal Light Massive Relics from Future CMB Experiments (CMB-S4/Simons Observatory)
Arka Banerjee, Abhik Bhattacharjee, Subinoy Das +2
In this work we present Fisher forecasts on \textit{non-thermal LiMR} models for a CMB Stage IV-like experiment and the Simons Observatory -- particularly focusing on a model of in…
