Stellar Objects From Quantum Gravity
Salvatore Samuele Sirletti, Piero Nicolini, Mariafelicia De Laurentis
This paper explores the theoretical implications of quantum gravity by analyzing compact stellar objects, presenting three distinct models that serve as alternatives to traditional…
Separating the Inseparable: Constraining Arbitrary Primordial Bispectra with Cosmic Microwave Background Data
Oliver H. E. Philcox, Kunhao Zhong, Salvatore Samuele Sirletti
To efficiently probe primordial non-Gaussianity using Cosmic Microwave Background (CMB) data, we require theoretical predictions that are factorizable, \textit{i.e.}\ those whose k…
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.…
Third-order corrections to the slow-roll expansion: calculation and constraints with Planck, ACT, SPT, and BICEP/Keck
Mario Ballardini, Alessandro Davoli, Salvatore Samuele Sirletti
We investigate the primordial power spectra (PPS) of scalar and tensor perturbations, derived through the slow-roll approximation. By solving the Mukhanov-Sasaki equation and the t…
Echoes from a long time ago: Chewbacca inflation
D. Sidious, S. Arcari, N. Barbieri +9
The cosmic microwave background (CMB) radiation offers a unique avenue for exploring the early Universe's dynamics and evolution. In this paper, we delve into the fascinating realm…
