Hubble Tension or Distance Ladder Crisis?
Leandros Perivolaropoulos
We present an up-to-date compilation of published Hubble constant () measurements that are independent of the CMB sound horizon scale. This compilation is split in two distinc…
Effects of a local physics change on the SH0ES determination of
Ruchika, Leandros Perivolaropoulos, Alessandro Melchiorri
The Hubble tension, a significant discrepancy between the Hubble constant () values derived from early-time (Cosmic Microwave Background and Baryon Acoustic Oscillations) and…
Hubble tension tomography: BAO vs SnIa distance tension
Dimitrios Bousis, Leandros Perivolaropoulos
We investigate the redshift dependence of the Hubble tension by comparing the luminosity distances obtained using an up-to-date BAO dataset (including the latest DESI data) calibra…
Special Issue on Modified Gravity Approaches to the Tensions of CDM: Goals and Highlights
Eleonora Di Valentino, Leandros Perivolaropoulos, Jackson Levi Said
The Special Issue on "Modified Gravity Approaches to the Tensions of CDM"} in the Universe journal tackles significant challenges faced by the CDM model, including discrepanc…
Transition dynamics in the CDM model: Implications for bound cosmic structures
Evangelos A. Paraskevas, Arman Cam, Leandros Perivolaropoulos +1
We explore the predictions of CDM, a novel framework suggesting a rapid anti-de Sitter (AdS) to de Sitter (dS) vacua transition in the late Universe, on bound cosmic str…
