Testing cosmic acceleration from thermogravity without vacuum energy
Dong Ha Lee, João Magueijo, Carsten van de Bruck +1
We present a first background-level observational test of a thermogravity theory in which the Einstein equations are clipped to a trace-free version, the cosmological constant …
Hunting Thermal Relics in the DESI DR1 Ly Forest
Emanuelly Silva, Artur Ladeira, Rafael C. Nunes +1
We investigate constraints on additional relativistic species and thermal sterile neutrinos using the DESI DR1 one-dimensional Lyman- forest power spectrum, combined with Planck…
Cosmological anatomy of interacting dark energy
Miguel A. Sabogal, Sunny Vagnozzi, Eleonora Di Valentino
Interacting dark energy (IDE) models, featuring interactions between dark matter (DM) and dark energy (DE), have received significant renewed interest. However, little attention ha…
FOSSIL: A future mission for CMB spectral distortion measurements
N. Aghanim, B. Maffei, J. Aumont +96
We present FOSSIL, a proposed space mission which is designed to deliver unprecedented absolute spectroscopic measurements of the sky intensity over a broad frequency range (50GHz…
Peering Beyond the Veil of Last Scattering: A View of the Universe with CMB Spectral Distortions
Bryce Cyr, Nabila Aghanim, Ethan Baker +37
The frequency spectrum of the cosmic microwave background is the most precise blackbody ever measured in nature, with deviations constrained at the level of almost one part per mil…
Late-Time Emergence of Dark Energy and Its Interaction with Dark Matter
Sibo Zhang, Weiqiang Yang, Supriya Pan +3
We present an interacting scenario between dark energy (DE) and dark matter (DM), where DE has an emergent nature, that means, DE was absent in the early universe but it becomes ef…
