The hydrodynamical response of cold circumgalactic clouds to quasar radiation

Nicolas Ledos, Sebastiano Cantalupo, Titouan Lazeyras +8

Recent simulations increasingly resolve the small-scale structure of the circumgalactic medium (CGM), but the dynamical impact of ionising radiation on its cold K component…

X-ray view of a massive node of the Cosmic Web at z=3 II. Discovery of extended X-ray emission around a hyperluminous QSO

Andrea Travascio, Sebastiano Cantalupo, Gabriele Pezzulli +17

While the warm, ionized gas in the CGM at z>3 is now routinely observed around bright QSOs in Lya emission, little is known about the CGM hot phase due to its expected faintness in…
