Topological Gravity as the Early Phase of Our Universe
Prateek Agrawal, Sergei Gukov, Georges Obied +1
Motivated by string dualities we propose topological gravity as the early phase of our universe. The topological nature of this phase naturally leads to the explanation of many of…
Axion string signatures II: A cosmological plasma collider
Prateek Agrawal, Anson Hook, Junwu Huang +1
We study early and late time signatures of both QCD axion strings and hyperlight axion strings (axiverse strings). We focus on charge deposition onto axion strings from electromagn…
Systematizing the Effective Theory of Self-Interacting Dark Matter
Prateek Agrawal, Aditya Parikh, Matthew Reece
If dark matter has strong self-interactions, future astrophysical and cosmological observations, together with a clearer understanding of baryonic feedback effects, might be used t…
