Slowly Rolling on a Quantum Correction
Ido Ben-Dayan, Ayushi Srivastava, Amresh Verma
Recent advances in cosmological measurements such as DESI and ACT may indicate an increase in the preferred value of the spectral tilt such that it disfavors rather popular m…
Towards a Proof of the Improved Quantum Null Energy Condition
Ido Ben-Dayan, Ayushi Srivastava
The Improved Quantum Null Energy Condition (INEC) was recently derived from the (restricted) quantum focusing conjecture (QFC), and is a statement about the energy-momentum tensor…
Disentangling the Origins of the NANOGrav Signal: Early Universe Models and Bounds
Ido Ben-Dayan, Utkarsh Kumar, Amresh Verma
We investigate whether an Early-Universe stochastic gravitational-wave background (SGWB) can account for the common spectrum process reported by NANOGrav, while also being consiste…
Suppressed Intrinsic Curvature Gravity
Ido Ben-Dayan, Elena Emtsova
We consider various mechanisms of modifying the effect of intrinsic curvature in gravity with respect to General Relativity. Two primary approaches for suppressing intrinsic curvat…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Impact of Low ell's on Large Scale Structure Anomalies
Ido Ben-Dayan, Utkarsh Kumar, Meir Shimon +1
We scrutinize the reported lensing anomaly of the CMB by considering several phenomenological modifications of the lensing consistency parameter, . Considering Planck sp…
