A search was conducted for a hot intragroup medium in 109 low-redshift galaxy groups observed with the ROSAT PSPC. Evidence for diffuse, extended X-ray emission is found in at least 61 groups. Approximately one-third of these detections have not been previously reported in the literature. Most of the groups are detected out to less than half of the virial radius with ROSAT. Although some spiral-rich groups do contain an intragroup medium, diffuse emission is restricted to groups that contain at least one early-type galaxy.

Illuminating Low Surface Brightness Galaxies with the Hyper Suprime-Cam Survey (2017, background): “…is the third most massive collection of early-type galaxies in the local universe after the Virgo and Fornax clusters, and it has been studied extensively at many different wavelengths (e.g., Tully 1987; Mulchaey et al. 2003; Eigenthaler & Zeilinger 2010; Machacek et al. 2011; Marino et al. 2016).”
Pre-Processing of Galaxies before Entering a Cluster (2003, background): “At least for nearby clusters and groups, observations suggest that such non-gravitational heating did happen (Ponman et al. 1999; Lloyd-Davies et al. 2000; Mulchaey 2000; Mulchaey et al. 2003).”
The case for AGN feedback in galaxy groups (2009, methodology): “For comparison, we show in the left panel the ROSAT measurements of Helsdon & Ponman (2000) and Mulchaey et al. (2003) (temperatures uncorrected) and in the right panel the ROSAT measurements of Osmond & Ponman (2004) (cool core-corrected temperatures).”
The GEMS project: X-ray analysis and statistical properties of the group sample (2004, background): “There have been a number of previous studies of samples of galaxy groups based primarily on pointed ROSAT observations (e.g. Pildis, Bregman & Evrard 1995; Mulchaey et al. 1996; Ponman et al. 1996; Mulchaey & Zabludoff 1998; Helsdon & Ponman 2000a,b; Mulchaey et al. 2003).”
CHANDRA STUDIES OF THE X-RAY GAS PROPERTIES OF GALAXY GROUPS (2008, methodology): “We started to collect groups from several previous group samples constructed from ROSAT observations: Mahdavi et al. (2000), Mulchaey et al. (2003) and GEMS (Osmond, & Ponman 2004).”
