Euclid : Finding strong gravitational lenses in the early release observations using convolutional neural networks

B.C Nagam, J.A. Acevedo Barroso, J. Wilde, I.T Andika et autres

Several new galaxy-galaxy strong gravitational lenses have been detected in the early release observations (ERO) from Euclid . The all-sky survey is expected to find 170 000 new systems, which are expected to greatly enhancing studies of dark matter and dark energy, …

Measurements of galaxy clustering are affected by redshift-space distortions (RSDs). Peculiar velocities, gravitational lensing, and other light-cone projection effects modify the observed redshifts, fluxes, and sky positions of distant light sources. We determined which of these effects leave a detectable imprint on …

Euclid preparation: XVI. Exploring the ultra low-surface brightness Universe with Euclid/VIS

A. S. Borlaff, P. Gómez-Alvarez, R. Vavrek, R. Laureijs et autres

While Euclid is an ESA mission specifically designed to investigate the nature of Dark Energy and Dark Matter, the planned unprecedented combination of survey area ($\sim15\,000$ deg$^2$), spatial resolution, low sky-background, and depth also make Euclid an excellent space observatory for the …
