| We present several cases of circumgalactic nebular emission around intermediate-redshift galaxies in the MUSE eXtremely Deep Field (MXDF). While previous investigations using stacking techniques already found strong statistical evidence for extended emission around galaxies, it remained unclear whether this is a widespread phenomenon of the CGM or whether it is driven by a subset of systems with special properties. Here we focus on individual detections (as well as carefully accounting for non-detections) of circumgalactic H-alpha, H-beta, [O II], and [O III] emission traced out to distances of several hundred physical kpc. Our MXDF data enable us to reach a surface brightness sensitivity of below 10^-20 erg cm^-2 s^-1 arcsec^-2 in individual sightlines, comparable to the deepest stacking experiments. We discuss the statistics of detecting (or not) the "CGM in emission" and relate this to the properties of the underlying parent galaxy sample. |
