J1721+8842: The first Einstein zigzag lens

Eric Gérard Guy Paic, Frédéric Dux

We report the discovery of the first example of an Einstein zigzag lens, an extremely rare lensing configuration. In this system, J1721+8842, six images of the same background quasar are formed by two intervening galaxies, one at redshift z(1) = 0.184 and ...

DESI 2024 VII: cosmological constraints from the full-shape modeling of clustering measurements

Antoine Philippe Jacques Rocher, Rafaela Gsponer

We present cosmological results from the measurement of clustering of galaxy, quasar and Lyman-α forest tracers from the first year of observations with the Dark Energy Spectroscopic Instrument (DESI Data Release 1). We adopt the full-shape (FS) modeling o ...

euclid Preparation: Lxiii. Simulations and Non-linearities Beyond Lambda Cold Dark Matter. 2. Results From Non-standard Simulations

Frédéric Courbin, Georges Meylan

The Euclid mission will measure cosmological parameters with unprecedented precision. To distinguish between cosmological models, it is essential to generate realistic mock observables from cosmological simulations that were run in both the standard Lambda ...
