International audience; Mighei-type carbonaceous chondrites (CM) figure among the most primitive objects in the solar system. Yet, they all have experienced various degrees of aqueous alteration having modified their insoluble organic matter (IOM), i

International audience; It's shown through the Janus cosmological model framework that the object responsible for the phenomenon called "dipole repeller" is a spheroidal cluster made exclusively with anti-hydrogen and anti-helium of dark matter of ne

Radio used as a star formation rate (SFR) tracer presents enormous advantages by being unaffected by dust and radio sources being pinpointed at the sub-arc-second level. The interpretation of the low frequency 1.4 GHz luminosity is hampered by the di

Weak lensing mass-mapping is a useful tool to access the full distribution of dark matter on the sky, but because of intrinsic galaxy ellipticies and finite fields/missing data, the recovery of dark matter maps constitutes a challenging ill-posed inv

Gravitational lensing is the distortion of the images of distant galaxies by intervening massive objects and constitutes a powerful probe of the Large Scale Structure of our Universe. Cosmologists use weak (gravitational) lensing to study the nature

The distribution of matter on cosmological scales can be predicted in the framework of the LambdaCDM model. It depends, among other things, on the properties of dark matter and neutrinos. Large spectroscopic surveys, such as eBOSS and DESI, aim to pr

The arrival of new telescopes and the improvement of the techniques of numerical simulations allow important progress to be made in the understanding of the mechanisms of star formation in the Universe. It's a major challenge, because star formation

International audience; Context. Massive star-formation leads to enrichment with heavy elements of the interstellar medium. On the other hand, the abundance of heavy elements is a key parameter to study the star-formation history of galaxies. Further

Cosmological simulations aim to understand the matter distribution in the universe either by following a semi-analytic approach or by formulating a hydrodynamical version of the matter distribution. Both approaches describe the evolution of baryonic

(abridged) Quantifying the ISM porosity to ionizing photons in nearby galaxies may improve our understanding of the mechanisms leading to Lyman Continuum photons leakage from galaxies. Primitive galaxies with low metal and dust content have been show
