X-ray Chandra or XMM-Newton images (O’Sullivan et al. 2017) for the sources that have a detected IGrM. Hα contours are overlaid in orange from our MUSE observations. Contours from 610 MHz GMRT radio emission are shown with dashed gray lines. Buoyant X-ray cavities are marked with white arrows. The X-ray bubbles for NGC 5846 and NGC 777 have been identified by Panagoulia et al. (2014), whereas for NGC 193 by Bogdán et al. (2014). Possible X-ray cavities are also shown for NGC 677 and NGC 1453. North is up, east is left.
