From Cosmology to Cosmonomy
Emmanuel N. Saridakis
For most of its history, cosmology was a qualitatively constrained discourse on the universe, shaped by limited observational access and the absence of global dynamical laws. This…
Decoupling perturbations from background in gravity: the square-root correction and the impact on the tension
Chunyu Li, Xin Ren, Yuhang Yang +2
We investigate a perturbation-level modification of symmetric teleparallel gravity of the form and assess its potential to ease the tension. The square-…
Probing the sound speed and clustering of dark energy
Yuhang Yang, Qingqing Wang, Xin Ren +2
Recent Dark Energy Spectroscopic Instrument (DESI) observations favor a dynamical dark energy component with a time-varying equation-of-state, potentially crossing the cosmological…
Cosmological tensions in the era of precision cosmology: Insights from Tensions in Cosmology 2025
Eleonora Di Valentino, Jackson Levi Said, Emmanuel N. Saridakis
The ``Tensions in Cosmology'' series of conferences has been established as one of the main venues where the cosmological community collectively assesses the cracks in the concorda…
Inflation from a generalized exponential plateau: towards extra suppressed tensor-to-scalar ratios
Gerasimos Kouniatalis, Emmanuel N. Saridakis
We investigate a standard minimally-coupled scalar-field inflationary scenario, which is based on a new potential, with suitably generalized plateau features, that leads to extra s…
Is Dark Energy an Effective Manifestation of Non-equilibrium Thermodynamics? -- Insights from DESI
Sauvik Bhattacharjee, Sudip Halder, Jaume de Haro +2
We investigate the background cosmological expansion on the onset of cosmological homogeneous matter creation scenario, a dynamical dark matter approach (), and…
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.…
Interacting dark energy after DESI DR2: a challenge for CDM paradigm?
Supriya Pan, Sivasish Paul, Emmanuel N. Saridakis +1
We investigate the scenario of interacting dark energy through a detailed confrontation with various observational datasets. We quantify the interaction in a general way, through t…
