Radio halo detection in MWA data using deep neural networks and generative data augmentation

Jean-Paul Richard Kneib, Emma Elizabeth Tolley

Detecting diffuse radio emission, such as from haloes, in galaxy clusters is crucial for understanding large-scale structure formation in the universe. Traditional methods, which rely on X-ray and Sunyaev-Zeldovich (SZ) cluster pre-selection, introduce bia ...

S-R2D2: a spherical extension of the R2D2 deep neural network series paradigm for wide-field radio-interferometric imaging

Jean-Philippe Thiran, Jean-Paul Richard Kneib, Emma Elizabeth Tolley

Recently, the R2D2 paradigm, standing for ‘Residual-to-Residual DNN series for high-Dynamic-range imaging’, was introduced for image formation in Radio Interferometry (RI) as a learned version of the traditional algorithm CLEAN. The first incarnations of R ...

Deep Learning to Improve the Discovery of Near-earth Asteroids in the Zwicky Transient Facility

Jean-Paul Richard Kneib, Mathieu Salzmann, Belén Yu Irureta-Goyena Chang

We present a novel pipeline that uses a convolutional neural network (CNN) to improve the detection capability of near-Earth asteroids (NEAs) in the context of planetary defense. Our work aims to minimize the dependency on human intervention of the current ...

Euclid: Early Release Observations – A preview of the Euclid era through a galaxy cluster magnifying lens

Jean-Paul Richard Kneib, Frédéric Courbin, Georges Meylan

We present the first analysis of the Euclid Early Release Observations (ERO) program that targets fields around two lensing clusters, Abell 2390 and Abell 2764. We use imaging data from the Visible instrument (VIS) and the Near-Infrared Spectrometer and Ph ...

ELG spectroscopic systematics analysis of the DESI Data Release 1

Jean-Paul Richard Kneib, Jiaxi Yu, Daniel Felipe Forero Sanchez

Dark Energy Spectroscopic Instrument (DESI) uses more than 2.4 million Emission Line Galaxies (ELGs) for 3D large-scale structure (LSS) analyses in its Data Release 1 (DR1). Such large statistics enable thorough research on systematic uncertainties. In thi ...

Euclid I. Overview of the Euclid mission

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

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 ...
