Chandra Survey of Nearby Edge-on Disk Galaxies I: Luminosities of Galactic Coronae

Understand

X-ray-emitting coronae of nearby galaxies are expected to be produced either by accretion from the intergalactic medium and/or by various galactic feedback.

• We herein present a systematical analysis of the Chandra observations of 53 nearby edge-on disk galaxies over a range of 3 orders of magnitude in SFR.
• Various coronal properties, such as the luminosity, vertical/horizontal extent, and other inferred parameters, are characterized for all the sample galaxies.
• For galaxies with high enough counting statistics, we also examine the thermal and chemical states of the coronal gas.
