18 UV bright QSOs obs. with HST (COS-IGrM survey)
Listed in IVOA Registry (Virtual Observatory)
We present the results of the Cosmic Origins Spectrograph-Intragroup Medium (COS-IGrM) Survey that used the COS on the Hubble Space Telescope to observe a sample of 18 UV bright quasars, each probing the IGrM of a galaxy group.
Description
We detect Ly{alpha}, CII, NV, SiII, SiIII, and OVI in multiple sightlines. The highest ionization species detected in our data is OVI, which was detected in eight out of 18 quasar sightlines.
The wide range of ionization states observed provide evidence that the IGrM is patchy and multiphase. We find that the OVI detections generally align with radiatively cooling gas between 105.8 and 106K. The lack of OVI detections in 10 of the 18 groups illustrates that OVI may not be the ideal tracer of the volume filling component of the IGrM.

Instead, it either exists at trace levels in a hot IGrM or is generated in the boundary between the hotter IGrM and cooler gas.
