Unveiling large-scale rotational motions in the intragroup medium at z~1 through gravitational-arc tomography

Cédric Ledoux, Fernanda Muñoz-Olivares, L. Felipe Barrientos +8

We present the first spatially resolved characterisation of the cool intragroup medium (IGrM) in a spectroscopically confirmed galaxy group at z=1.167. Using 30 independent sightli…
