Comparing Compressed and Full-Modeling analyses with FOLPS: implications for DESI 2024 and beyond

The Dark Energy Spectroscopic Instrument (DESI) will provide unprecedented information about the large-scale structure of our Universe. In this work, we study the robustness of the theoretical modelling of the power spectrum of FOLPS, a novel effective fie ...

Euclid I. Overview of the Euclid mission

Jean-Paul Richard Kneib, Frédéric Courbin, Georges Meylan, Pascale Jablonka, Michaela Hirschmann, Yves Revaz, Austin Chandler Peel, Lucie Anemone Scharré, Bastien Clément

The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Euclid is a medium-class mission in the Cosmic Vision 2015–2025 programme of the ...

Euclid V. The Flagship galaxy mock catalogue: A comprehensive simulation for the Euclid mission

Frédéric Courbin, Georges Meylan

We present the Flagship galaxy mock, a simulated catalogue of billions of galaxies designed to support the scientific exploitation of the Euclid mission. Euclid is a medium-class mission of the European Space Agency optimised to determine the properties of ...

Euclid preparation: XLII. A unified catalogue-level reanalysis of weak lensing by galaxy clusters in five imaging surveys

Frédéric Courbin, Georges Meylan, Austin Chandler Peel

Precise and accurate mass calibration is required to exploit galaxy clusters as astrophysical and cosmological probes in the Euclid era. Systematic errors in lensing signals by galaxy clusters can be empirically estimated by comparing different surveys wit ...

The stringy S-matrix bootstrap: maximal spin and superpolynomial softness

Kelian Philippe Häring

We explore the space of meromorphic amplitudes with extra constraints coming from the shape of the leading Regge trajectory. This information comes in two guises: it bounds the maximal spin of exchanged particles of a given mass; it leads to sum rules obey ...

Discovery of two bright high-redshift gravitationally lensed quasars revealed by Gaia

Cameron Alexander Campbell Lemon

We present the discovery and preliminary characterisation of two high-redshift gravitationally lensed quasar systems in Gaia Data Release 2 (DR2). Candidates with multiple close-separation Gaia detections and quasar-like colours in WISE, Pan-STARRS, and DE ...

Hypermagnetogenesis from axion inflation: Model-independent estimates

Oleksandr Sobol

Axion inflation coupled to the Standard Model (SM) hypercharge gauge sector represents an attractive scenario for the generation of primordial hypemiagnetic fields. The description of this scenario is, however, complicated by the Schwinger effect, which gi ...
