Decay of quintessence into dark matter: mitigating the Hubble tension?
Giovanni Montani, Luis A. Escamilla, Nakia Carlevaro +1
We propose a revised cosmological scenario that extends the Cold Dark Matter (CDM) framework by incorporating metric gravity in the Jordan frame. In this model, the d…
BAO miscalibration cannot rescue late-time solutions to the Hubble tension
Davide Pedrotti, Luis A. Escamilla, Valerio Marra +2
Baryon Acoustic Oscillation (BAO) measurements play a key role in ruling out post-recombination solutions to the Hubble tension. However, because the data compression leading to th…
When Dark Matter Heats Up: A Model-Independent Search for Non-Cold Behavior
Mazaharul Abedin, Luis A. Escamilla, Supriya Pan +2
This article questions the common assumption of cold dark matter (DM) by exploring the possibility of a non-zero equation of state (EoS) without relying on any parametric approach.…
Pressure Parametrization of Dark Energy: First and Second-Order Constraints with Latest Cosmological Data
Hanyu Cheng, Eleonora Di Valentino, Luis A. Escamilla +2
We explore an extension of the CDM model in which the pressure of the dark energy (DE) fluid evolves with the expansion of the Universe, expressed as a function of the scale…
False Discovery Controlled Regions for Excursion Sets
Howon Ryu, Thomas Maullin-Sapey, Armin Schwartzman +1
Identifying areas where the signal is prominent is an important task in image analysis, with particular applications in brain mapping. In this work, we develop False Discovery Cont…
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.…
Exploring the Growth-Index () Tension with CDM
Luis A. Escamilla, Özgür Akarsu, Eleonora Di Valentino +2
Recent observational analyses have revealed a significant tension in the growth index , which characterizes the growth rate of cosmic structures. Specifically, when treating …
