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.…
Listening to Celestial Algebras
Jose Beltrán Jiménez, Tomi S. Koivisto
In this essay, we immerse into the framework of normed division algebras as a suitable arena to accommodate the standard model of elementary particles, and we explore some applicat…
Cosmological black holes are not described by the Thakurta metric: LIGO-Virgo bounds on PBHs remain unchanged
Gert Hütsi, Tomi Koivisto, Martti Raidal +2
We show that the physical conditions which induce the Thakurta metric, recently studied by Bœhm {\it et al.} in the context of time-dependent black hole masses, correspond to a sin…
Non-Gaussianity in multi-sound-speed disformally coupled inflation
Carsten van de Bruck, Tomi Koivisto, Chris Longden
Most, if not all, scalar-tensor theories are equivalent to General Relativity with a disformally coupled matter sector. In extra-dimensional theories such a coupling can be underst…
Cosmology and Fundamental Physics with the Euclid Satellite
Luca Amendola, Stephen Appleby, Anastasios Avgoustidis +69
Euclid is a European Space Agency medium class mission selected for launch in 2020 within the Cosmic Vision 2015 2025 program. The main goal of Euclid is to understand the origin o…
Disformally coupled inflation
Carsten van de Bruck, Tomi Koivisto, Chris Longden
A disformal coupling between two scalar fields is considered in the context of cosmological inflation. The coupling introduces novel derivative interactions mixing the kinetic term…
