The association between water kilomasers and compact radio sources in the starburst galaxy NGC 2146.

TARCHI A., HENKEL C., PECK A.B. and MENTEN K.M.

Abstract (from CDS):

We report the detection of 22 GHz water vapor emission toward the starburst galaxy NGC 2146, made using the Effelsberg 100-m telescope. Interferometric observations with the Very Large Array (VLA) show that a part of the emission originates from two prominent sites of star formation that are associated with compact radio continuum sources, likely ultra-compact HII regions. It is concluded that the emission arises from the most luminous and distant H2O ``kilomasers'' detected so far. Our data increase the number of water maser detections in northern galaxies (Dec>-30°) with IRAS point source fluxes S100µm>50Jy to 18%.
