MAGNUS. II. Rotational Support of Massive Early Type Galaxies Decreased Over the Past 7 Gyr

P. Mozumdar, Michele Cappellari, Christopher D. Fassnacht, Tommaso Treu

Abstract Understanding how the internal kinematics of massive galaxies evolve is key to constraining the physical processes that drive their assembly. We investigate the evolution of rotational support in massive ( log M * / M ⊙ ≥ 10.6 ) early-type galaxies …

Measurement of the Minimum Cold Dark Matter Halo Mass with Strong Gravitational Lensing

Anna M Nierenberg, Daniel Gilman, T. Treu, Xiaolong Du et autres

We explore the lowest mass limit that can be placed on the halo mass function in cold dark matter (CDM) using 28 strong gravitational lenses. For this purpose, we study an extreme model in which the halo mass function and mass-concentration relation …

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 …
