Deus ex -- Is evidence for dynamical dark energy conditioned on early cosmology?
Nils Schöneberg, Rodrigo Calderón, Julien Lesgourgues
Some free-form reconstructions of the dark energy equation of state suggest that dynamical dark energy is the only explanation for the observed data. In this letter we argue that e…
Charging Across the Phantom Divide with Modified Gravity
Rodrigo Calderon, Eric V. Linder
Cosmology where the effective dark energy crosses can be realized in Horndeski gravity with shift symmetric terms plus a linear potential. We highlight the special role of t…
Impact of ACT DR6 and DESI DR2 for Early Dark Energy and the Hubble tension
Vivian Poulin, Tristan L. Smith, Rodrigo Calderón +1
The data release six of the Atacama Cosmology Telescope (ACT DR6) and the second data release from the Dark Energy Spectroscopic Instrument (DESI DR2) recently became available. In…
Model-independent cosmology with joint observations of gravitational waves and -ray bursts
Andrea Cozzumbo, Ulyana Dupletsa, Rodrigo Calderón +3
Multi-messenger (MM) observations of binary neutron star (BNS) mergers provide a promising approach to trace the distance-redshift relation, crucial for understanding the expansion…
On the implications of the `cosmic calibration tension' beyond and the synergy between early- and late-time new physics
Vivian Poulin, Tristan L. Smith, Rodrigo Calderón +1
The `cosmic calibration tension' is a discrepancy between the cosmological distance ladder built from baryonic acoustic oscillations (BAO) calibrated by the Planck/CDM so…
