Talk

We present a lensing model for the ERO cluster A2390 combining strong and weak lensing data from Euclid. Euclid's large feld of view offers unique opportunities to constrain with precision the masses of the most massive clusters, which opens a door for cosmology.

23. Denoising and Measuring Galaxy Shapes with Deep Learning

Talk

The two current main methods to measure shear, model-fitting and moments-based, both suffer from noise bias for galaxies with lower SNR. As Euclid has very strict requirements for shear bias, there is motivation to remove noise from images before performing the shape measurement to increase the precision. We present two deep learning algorithms: one to denoise galaxy images and another to...

7. Submillimeter galaxies Magnification bias: an interesting opportunity with/for Euclid

Joaquín González-Nuevo (Universidad de Oviedo)

Talk

This presentation synthesizes findings from our recent studies, that focus on the magnification bias observed in high-redshift submillimeter galaxies (SMGs). Our methodology employs SMGs as a background sample, emphasizing their distinctive cross-correlation signals and their role as an alternative, independent probe for cosmological studies related to mass distribution. Precise measurements...
