Toward Precision Kinetic Sunyaev-Zel'dovich Cosmology---1. The Matter - Momentum Bispectrum at One-Loop Order
Ryan Raikman, James M. Sullivan, Jamie Sullivan +1
The kinetic Sunyaev-Zeldovich (kSZ) effect is a sensitive probe of the free-electron momentum field, tapping into spatial correlations relevant for both large-scale cosmology and s…
Kinetic Mixing and the Phantom Illusion: Axion-Dilaton Quintessence in Light of DESI DR2
Michael W. Toomey, Ellie Hughes, Mikhail M. Ivanov +1
Recent results from DESI BAO analyses suggest that dark energy may not be a cosmological constant and is in fact dynamical. Furthermore, the data suggest that the equation of state…
Equilateral non-Gaussian Bias at the Field Level
Divij Sharma, James M. Sullivan, Kazuyuki Akitsu +1
Primordial non-Gaussianity (PNG) is a common prediction of a wide class of inflationary models. Equilateral-type PNG, generically predicted by single-field inflationary models with…
Love numbers of black p-branes: fine tuning, Love symmetries, and their geometrization
Panagiotis Charalambous, Sergei Dubovsky, Mikhail M. Ivanov
We compute scalar static response coefficients (Love numbers) of non-dilatonic black -brane solutions in higher dimensional supergravity. This calculation revels a fine-tuning b…
