[184.05] A Very Large Array Survey for Water Maser Activity in Two HII Regions

K. R. Healy (Arizona State), M. J. Claussen (NRAO), J. J. Hester (Arizona State)

Previous surveys for water maser activity associated with star formation in H~II regions have had relatively low sensitivity, small angular coverage, or both. We present the results of an extensive search for water maser emission associated with young stellar objects in two H~II regions --- M16 and NGC~2175 --- conducted with the NRAO Very Large Array in August and September 2004. We report the detection of several previously unreported water masers in both H~II regions. The observed spatial distribution of the new masers lends further support to the youngest stages of star formation occurring in close proximity to the H~II region-molecular cloud interface. We present the positions and spectra of the newly discovered masers in M16 and NGC~2175 and discuss the local environments of the young stellar objects.

The NRAO is operated by Associated Universities, Inc. under cooperative agreement with the National Science Foundation.
