Modified gravity, gravitational waves and the large-scale structure of the Universe: A brief report
Ippocratis D. Saltas, Luca Amendola, Martin Kunz +1
The goal of this short report is to summarise some key results based on our previous works on model independent tests of gravity at large scales in the Universe, their connection w…
Type I Abelian Higgs strings: evolution and Cosmic Microwave Background constraints
Mark Hindmarsh, Joanes Lizarraga, Jon Urrestilla +2
We present results from the first simulations of networks of Type I Abelian Higgs cosmic strings to include both matter and radiation eras and Cosmic Microwave Background (CMB) con…
Bias and scatter in the Hubble diagram from cosmological large-scale structure
Julian Adamek, Chris Clarkson, Louis Coates +2
An important part of cosmological model fitting relies on correlating distance indicators of objects (for example type Ia supernovae) with their redshift, often illustrated on a Hu…
Planck 2018 results. III. High Frequency Instrument data processing and frequency maps
Planck Collaboration, N. Aghanim, Y. Akrami +152
This paper presents the High Frequency Instrument (HFI) data processing procedures for the Planck 2018 release. Major improvements in mapmaking have been achieved since the previou…
Intensity mapping of the 21cm emission: lensing
Mona Jalilvand, Elisabetta Majerotto, Ruth Durrer +1
In this paper, we study lensing of 21cm intensity mapping (IM). Like in the cosmic microwave background (CMB), there is no first order lensing in intensity mapping. The first effec…
Redshift-space distortions from vector perturbations II: Anisotropic signal
Vittorio Tansella, Camille Bonvin, Giulia Cusin +3
We study the impact on the galaxy correlation function of the presence of a vector component in the tracers' peculiar velocities, in the case in which statistical isotropy is viola…
