Cosmological constraints on dark energy in light of gravitational wave bounds

Johannes Noller

Gravitational wave (GW) constraints have recently been used to significantly restrict models of dark energy and modified gravity. New bounds arising from GW decay and GW-induced da…

Positivity in the sky

Scott Melville, Johannes Noller

Positivity bounds - the consequences of requiring a unitary, causal, local UV completion - place strong restrictions on theories of dark energy and/or modified gravity. We derive a…

Cosmological parameter constraints for Horndeski scalar-tensor gravity

Johannes Noller, Andrina Nicola

We present new cosmological parameter constraints for general Horndeski scalar-tensor theories, using CMB, redshift space distortion, matter power spectrum and BAO measurements fro…

Radiative stability and observational constraints on dark energy and modified gravity

Johannes Noller, Andrina Nicola

We investigate the radiative stability of Horndeski scalar-tensor theories with luminally propagating gravitational waves (as extensively discussed in the wake of GW170817) and sho…

Inflation in a scale invariant universe

Pedro G. Ferreira, Christopher T. Hill, Johannes Noller +1

A scale-invariant universe can have a period of accelerated expansion at early times: inflation. We use a frame-invariant approach to calculate inflationary observables in a scale…

Observational constraints on generalized Proca theories

Antonio De Felice, Lavinia Heisenberg, Shinji Tsujikawa

In a model of the late-time cosmic acceleration within the framework of generalized Proca theories, there exists a de Sitter attractor preceded by the dark energy equation of state…

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…

Cosmology in doubly coupled massive gravity: constraints from SNIa, BAO and CMB

Lavinia Heisenberg, Alexandre Refregier

Massive gravity in the presence of doubly coupled matter field via en effective composite metric yields an accelerated expansion of the universe. It has been recently shown that th…

Beyond CDM: Problems, solutions, and the road ahead

Philip Bull, Yashar Akrami, Julian Adamek +37

Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, CDM. This is motivated by a range o…

Cosmic Microwave Background Spectral Distortions from Cosmic String Loops

Madeleine Anthonisen, Robert Brandenberger, Alex Laguë +2

Cosmic string loops contain cusps which decay by emitting bursts of particles. A significant fraction of the released energy is in the form of photons. These photons are injected n…
