Limits on Ionized Gas in M81's Globular Clusters

Wrobel, J. M. · Johnson, K. E.

Original · EN

We use NSF's Karl G. Jansky Very Large Array to constrain the mass of ionized gas in 206 globular star clusters (GCs) in M81, a nearby spiral galaxy. We detect none of the GCs and impose a typical gas-mass upper limit of 550 solar masses (3-sigma). These findings bear on GC evolution in M81.
