H2O and OH maser emission from bright IRAS galaxies.
01 January 1986
H2O maser emission with an isotropic luminosity of 1 L(solar) has been detected in IC10. The maser, located at R.A.=O(h)17 (m)44.3(s), Dec=59degrees00'36" (+-10"; 1950.0). is the most powerful yet detected in a compact irregular galaxy. The H2O features at -332, -327 and -324 kms(-1) are confined to a region =10" (=150 pc) in size. The main velocity component is highly variable, and might represent a flare more intense than that found in Orion. CO is also detected at a velocity of -330 kms(-1).
