CosmoVerse Data Challenge: How Tip of the Red Giant Branch Analysis Choices Shape the Inferred Hubble Constant
Siyang Li, Eleonora Di Valentino, Jackson Levi Said +62
Tip of the red giant branch (TRGB)-based determinations of the Hubble constant (), the current expansion rate of the Universe, depend on choices made in selecting and analyzin…
Curvature-Radiation Geometries Across the Second CHIME/FRB Fast Radio Burst Population
Thonimar V. Alencar, Jéferson A. S. Fortunato, Wiliam S. Hipólito-Ricaldi
We present a population-level spectral analysis of fast radio bursts from the second CHIME/FRB catalog using three curvature-radiation-motivated templates: point-source, one-dimens…
Probing Cosmic Curvature with Fast Radio Bursts and DESI DR2
Jéferson A. S. Fortunato, Wiliam S. Hipólito-Ricaldi, Gustavo E. Romero
The spatial curvature of the Universe remains a central question in modern cosmology. In this work, we explore the potential of localized Fast Radio Bursts (FRBs) as a novel tool t…
Fast Radio Bursts and Artificial Neural Networks: a cosmological-model-independent estimation of the Hubble Constant
Jéferson A. S. Fortunato, David J. Bacon, Wiliam S. Hipólito-Ricaldi +1
Fast Radio Bursts (FRBs) have emerged as powerful cosmological probes in recent years offering valuable insights into cosmic expansion. These predominantly extragalactic transients…
Cosmography from well-localized Fast Radio Bursts
Jéferson A. S. Fortunato, Wiliam S. Hipólito-Ricaldi, Marcelo V. dos Santos
Fast Radio Bursts (FRBs) are millisecond-duration pulses occurring at cosmological distances that have emerged as prominent cosmological probes due to their dispersion measure (DM)…
