Dark energy, D-branes, and Pulsar Timing Arrays
Debika Chowdhury, Gianmassimo Tasinato, Ivonne Zavala
Several pulsar timing array (PTA) collaborations recently announced the first detection of a stochastic gravitational wave (GW) background, leaving open the question of its source.…
De Sitter vacua -- when are `subleading corrections' really subleading?
Bruno Valeixo Bento, Dibya Chakraborty, Susha Parameswaran +1
We consider various string-loop, warping and curvature corrections that are expected to appear in type IIB moduli stabilisation scenarios. It has recently been argued, in the conte…
String Cosmology: from the Early Universe to Today
Michele Cicoli, Joseph P. Conlon, Anshuman Maharana +3
We review applications of string theory to cosmology, from primordial times to the present-day accelerated expansion. Starting with a brief overview of cosmology and string compact…
A guide to frames, 's, scales and corrections in string compactifications
Bruno Valeixo Bento, Dibya Chakraborty, Susha Parameswaran +1
This note is intended to serve as a reference for conventions used in the literature on string compactifications, and how to move between them, collected in a single and easy-to-fi…
On the response of the Einstein Telescope to Doppler anisotropies
Debika Chowdhury, Gianmassimo Tasinato, Ivonne Zavala
We study the response function of the Einstein Telescope to kinematic Doppler anisotropies, which represent one of the guaranteed properties of the stochastic gravitational wave ba…
Sharp turns in axion monodromy: primordial black holes and gravitational waves
Sukannya Bhattacharya, Ivonne Zavala
Large turns in multifield inflation can lead to a very rich phenomenology, but are difficult to realise in supergravity, and typically require large field space curvatures. In this…
