We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

Pulsar timing array (PTA) collaborations in North America, Australia, and Europe, have been
exploiting the exquisite timing precision of millisecond pulsars over decades of observations …

We investigate interacting scenarios that belong to a wider class, since they include a
dynamical dark energy component whose equation of state follows various one-parameter …

We consider single-field inflation in light of string-motivated'swampland'conjectures
suggesting that effective scalar field theories with a consistent UV completion must have …

Context. The hot plasma in a galaxy cluster is expected to be heated to high temperatures
through shocks and adiabatic compression. The thermodynamical properties of the gas …

The phenomenological parametrizations of dark-energy (DE) equations of state can be very
helpful, since they allow for the investigation of its cosmological behavior despite the fact …

The Probe of Inflation and Cosmic Origins (PICO) is an imaging polarimeter that will scan the
sky for 5 years in 21 frequency bands spread between 21 and 799 GHz. It will produce full …

We investigate the impact of prior models on the upper bound of the sum of neutrino
masses,∑ m ν. Using data from the large scale structure of galaxies, cosmic microwave …

Gravitational-wave (GW) detectors can contribute to the measurement of cosmological
parameters and to testing the dark-energy sector of alternatives to ΛCDM, by using standard …

We investigate various scenarios which include interaction forms between dark matter and
dark energy that exhibit sign reverse, namely where the transfer of energy between the dark …
