Free-Streaming Length of Dark Matter from JWST Observations of 28 Strong Gravitational Lenses

Daniel Gilman, Anna M Nierenberg, Tommaso Treu, Kevork N. Abazajian et autres

The formation of gravitationally bound overdensities of dark matter (DM), or halos, is a generic prediction of theories with particle DM. We present a measurement of halo properties in 28 quadruple image strong lens systems recently observed by JWST, and use these …

Euclid Preparation : XIV. The Complete Calibration of the Color–Redshift Relation (C3R2) Survey: Data Release 3

Euclid Collaboration, S. A. Stanford, D. Masters, B. Darvish et autres

The Complete Calibration of the Color-Redshift Relation (C3R2) survey is obtaining spectroscopic redshifts in order to map the relation between galaxy color and redshift to a depth of i ~ 24.5 (AB). The primary goal is to enable sufficiently accurate photometric redshifts …
