Observations of H2O and OH masers in star-forming regions
Abstract
We report long-term observations of H2O and OH maser emission sources at wavelengths of 1.35 and 18 cm associated with star-forming regions. Strong quasi-periodic flares of maser emission have been observed. Several sources (in particular, G25.65+1.05, IRAS 16293-2422, Cep A) have displayed strong flares in the H2O line, when their peak flux density raised by a few orders of magnitude above the quiet state. Possible causes of this are discussed.
