the Extensive Database of Astrophysical Maser Sources

Abstract
Observations of various types of objects in the northern sky were obtained at 44 GHz in the 7₀-6₁ A ⁺ methanol line on the 20-m Onsala radio telescope (Sweden), in order to search for Class I methanol maser emission in the interstellar medium: regions of formation of high-mass stars, dust rings around HII regions, and protostellar candidates associated with powerful molecular outflows and Galactic HII regions. Seven new Class Imethanolmasers have been discovered toward regions of formation of highmass stars, and the existence of two previously observed masers confirmed. The following conclusions are drawn: (1) neither the association of a bipolar outflow manifest in the wings of CO lines with a highmass protostellar object (HMPO) nor the presence of thermal emission in lines of complex molecules are sufficient conditions for the detection of Class I methanol emission no association with HMPOs radiating at 44 GHz was found for EGOs (a new class of object tracing bipolar outflows) (2) the existence of H₂O masers and Class II methanol masers in the region of aHMPOenhances the probability of detecting Class I methanol emission toward the HMPO Class II methanol masers with stronger line fluxes are associated with Class I methanol masers.	Coordinates IRAS or MSX Comments: (1) IRAS objects with color criteria of candidates of high-mass proto-stellar objects (2) Regions with massive molecular outflows from Qin et al. [19] that are associated with ultra-compact and compact HII regions (3) Proposed regions of formation of second-generation stars from Deharveng et al. [20] (4) Regions of formation of massive stars from Qiu et al. [21] containing young high-luminosity objects associated with molecular outflows.
