Unraveling Cosmological Anisotropies within Stochastic Gravitational Wave Backgrounds
Yanou Cui, Soubhik Kumar, Raman Sundrum +1
Identifying the anisotropies in a cosmologically sourced stochastic gravitational wave background (SGWB) would be of significance in shedding light on the nature of primordial inho…
Challenges in Interpreting the NANOGrav 15-Year Data Set as Early Universe Gravitational Waves Produced by ALP Induced Instability
Michael Geller, Subhajit Ghosh, Sida Lu +1
In this paper, we study a possible early universe source for the recent observation of a stochastic gravitational wave background at the NANOGrav pulsar timing array. The source is…
Probing Cosmological Particle Production and Pairwise Hotspots with Deep Neural Networks
Taegyun Kim, Jeong Han Kim, Soubhik Kumar +3
Particles with masses much larger than the inflationary Hubble scale, , can be pair-produced non-adiabatically during inflation. Due to their large masses, the produced partic…
Detecting Axion-Like Particles with Primordial Black Holes
Kaustubh Agashe, Jae Hyeok Chang, Steven J. Clark +3
Future gamma-ray experiments, such as the e-ASTROGAM and AMEGO telescopes, can detect the Hawking radiation of photons from primordial black holes (PBHs) if they make up a fraction…
Precision Cosmological Constraints on Atomic Dark Matter
Saurabh Bansal, Jared Barron, David Curtin +1
Atomic dark matter is a simple but highly theoretically motivated possibility for an interacting dark sector that could constitute some or all of dark matter. We perform a comprehe…
Recent Progress and Next Steps for the MATHUSLA LLP Detector
Cristiano Alpigiani, Juan Carlos Arteaga-Velázquez, Austin Ball +93
We report on recent progress and next steps in the design of the proposed MATHUSLA Long Lived Particle (LLP) detector for the HL-LHC as part of the Snowmass 2021 process. Our under…
