RENATA meeting 2025

Monday 22 Sept 2025, 08:45 → 22:30 Europe/Madrid

Sala de Grados (Facultad de Ciencias) (Universidad de Zaragoza)

Carmen Palomares (CIEMAT), David Cerdeño (IFT), Maria Martinez (CAPA - UZ)

The 2025 RENATA meeting will take place on September 22, 2025, in Zaragoza. The main objective of this meeting is to discuss and coordinate the Spanish strategy in view of the upcoming APPEC strategic roadmap 2027-2036 for astroparticle physics. The APPEC roadmap kickoff meeting will also be held in Zaragoza on September 23-24 (https://indico.cern.ch/event/1516919/)

This gathering will provide an opportunity for the different Spanish research groups involved in astroparticle physics to share updates, identify common goals, and contribute to a coordinated national input for the roadmap process.

Talks are by invitation only. All interested members of the spanish astroparticle community are welcome to participate and join the discussion.

13:15 The Dark Side of the Cosmos: Exploring Dark Energy and Modified Gravity

We are currently witnessing a remarkable era in the fields
of cosmology and gravitation, as an ever-increasing amount of
observational data continues to be collected. One of the most
perplexing questions confronting cosmologists today concerns the
mysterious source responsible for the Universe’s recent accelerated
expansion. The most widely accepted explanations for this phenomenon
involve either a dark energy component or a modified theory of
gravity. In this talk, we present, on the one hand, several dark
energy models, ranging from axion-like scalar fields and kinetic
gravity braiding models to 3-form fields. On the other hand, we
explore modified theories of gravity, in particular those based on
f(Q) gravity, as alternative explanations for the Universe’s current
accelerated expansion.We also discuss the observational constraints on
these models. Furthermore, we examine how they may contribute to a
potential resolution of the ongoing H_0 and S_8 tensions.
