Hubble tension or distance ladder crisis?
L Perivolaropoulos - Physical Review D, 2024 - APS
We present an up-to-date compilation of published Hubble constant (H 0) measurements
that are independent of the cosmic microwave background sound horizon scale. This …

On the convergence of cosmographic expansions in Lemaître–Tolman–Bondi models
We study cosmographic expansions of the luminosity distance for a variety of Lemaître–
Tolman–Bondi (LTB) models which we specify inspired by local large-scale structures of the …

Impact of lensing bias on the cosmological dispersion measure
R Takahashi - Journal of Cosmology and Astroparticle Physics, 2024 - iopscience.iop.org
The cosmological dispersion measure (DM) as a function of redshift, derived from localized
fast radio bursts (FRBs), has been used as a tool for constraining the cosmic ionized fraction …

Fast Radio Bursts as probes of the late-time universe: a new insight on the Hubble tension
S Kalita, S Bhatporia, A Weltman - arxiv preprint arxiv:2410.01974, 2024 - arxiv.org
Fast Radio Bursts (FRBs) are bright radio transient events, a subset of which have been
localized to their host galaxies. Their high dispersion measures offer valuable insights into …
