The growth of density perturbations in the last 10 billion years from tomographic large-scale structure data
Carlos García-García, Jaime Ruiz Zapatero, David Alonso +5
In order to investigate the origin of the ongoing tension between the amplitude of matter fluctuations measured by weak lensing experiments at low redshifts and the value inferred…
Fully relativistic predictions in Horndeski gravity from standard Newtonian N-body simulations
Guilherme Brando, Kazuya Koyama, David Wands +3
The N-body gauge allows the introduction of relativistic effects in Newtonian cosmological simulations. Here we extend this framework to general Horndeski gravity theories, and inv…
Theoretical priors in scalar-tensor cosmologies: Shift-symmetric Horndeski models
Dina Traykova, Emilio Bellini, Pedro G. Ferreira +3
Attempts at constraining theories of late time accelerated expansion often assume broad priors for the parameters in their phenomenological description. Focusing on shift-symmetric…
Comparison of different approaches to the quasi-static approximation in Horndeski models
Francesco Pace, Richard Battye, Emilio Bellini +3
A quasi-static approximation (QSA) for modified gravity can be applied in a number of ways. We consider three different analytical formulations based on applying this approximation…
Cross-correlating radio continuum surveys and CMB lensing: constraining redshift distributions, galaxy bias and cosmology
David Alonso, Emilio Bellini, Catherine Hale +2
We measure the harmonic-space auto-power spectrum of the galaxy overdensity in the LOFAR Two-metre Sky Survey (LoTSS) First Data Release and its cross correlation with the map of t…
Theoretical priors in scalar-tensor cosmologies: Thawing quintessence
Carlos García-García, Emilio Bellini, Pedro G. Ferreira +2
The late time acceleration of the Universe can be characterized in terms of an extra, time dependent, component of the universe -- dark energy. The simplest proposal for dark energ…
