Sound-Horizon-Agnostic Inference of the Hubble Constant and Neutrino Mass from BAO, CMB Lensing, and Galaxy Weak Lensing and Clustering
Helena GarcÃa Escudero, Seyed Hamidreza Mirpoorian, Levon Pogosian
We present a sound-horizon-agnostic determination of the Hubble constant, , by combining DESI DR2 baryon acoustic oscillation (BAO) data with the latest cosmic microwave backg…
Is Dynamical Dark Energy Necessary? DESI BAO and Modified Recombination
Seyed Hamidreza Mirpoorian, Karsten Jedamzik, Levon Pogosian
Recent measurements of baryon acoustic oscillations (BAO) by the Dark Energy Spectroscopic Instrument (DESI) exhibit a mild-to-moderate tension with cosmic microwave background (CM…
Hints of Primordial Magnetic Fields at Recombination and Implications for the Hubble Tension
Karsten Jedamzik, Levon Pogosian, Tom Abel
Primordial Magnetic Fields (PMFs), long studied as relics of the early Universe, accelerate recombination and have been proposed as a way to relieve the Hubble tension. However, pr…
Dynamical Dark Energy in light of the DESI DR2 Baryonic Acoustic Oscillations Measurements
Gan Gu, Xiaoma Wang, Yuting Wang +57
Understanding whether cosmic acceleration arises from a cosmological constant or a dynamical component is a central goal of cosmology, and the Dark Energy Spectroscopic Instrument…
Cosmic strings in the complex symmetron model
Ali Nezhadsafavi, Levon Pogosian
We study cosmic strings in the complex symmetron model, a scalar-tensor theory with a spontaneously broken local symmetry in low matter density regions. Using numerical simu…
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.…
