A New Galactic 6 cm Formaldehyde Maser
نویسندگان
چکیده
We report the detection of a new H 2 CO maser in the massive star forming region G23.71−0.20 (IRAS 18324−0820), i.e., the fifth region in the Galaxy where H 2 CO maser emission has been found. The new H 2 CO maser is located toward a compact H II region, and is coincident in velocity and position with 6.7 GHz methanol masers and with an IR source as revealed by Spitzer/IRAC GLIMPSE data. The coincidence with an IR source and 6.7 GHz methanol masers suggests that the maser is in close proximity to an embedded massive protostar. Thus, the detection of H 2 CO maser emission toward G23.71−0.20 supports the trend that H 2 CO 6 cm masers trace molecular material very near young massive stellar objects.

A Search for H2CO 6cm Emission toward Young Stellar Objects III: VLA Observations
We report the results of our third survey for formaldehyde (H2CO) 6 cm maser emission in the Galaxy. Using the Very Large Array, we detected two new H2CO maser sources (G23.01−0.41 and G25.83−0.18), thus increasing the sample of known H2CO maser regions in the Galaxy to seven. We review the characteristics of the G23.01−0.41 and G25.83−0.18 star forming regions. The H2CO masers in G23.01−0.41 a...
متن کاملThe 6 - GHz methanol multibeam maser catalogue I : Galactic Centre region , longitudes 345 ◦ to 6 ◦
We have conducted a Galactic plane survey of methanol masers at 6668 MHz using a 7-beam receiver on the Parkes telescope. Here we present results from the first part, which provides sensitive unbiased coverage of a large region around the Galactic Centre. Details are given for 183 methanol maser sites in the longitude range 345◦ through the Galactic Centre to 6◦. Within 6◦ of the Centre, we fou...
متن کاملResponse of circumnuclear water masers to luminosity changes in an active galactic nucleus
Circumnuclear water masers can respond in two ways to changes in the luminosity of an active galactic nucleus. First, an increase in the X-ray luminosity can lead to an increase in the maser emissivity; and second, an increase in the intrinsic bolometric luminosity may result in a temporary decrease in the difference between the gas and dust temperature and a consequent decrease in the maser ou...
متن کاملWater Masers Toward Ultracompact HII Regions
We present a survey in the 6 16 − 5 23 rotational H 2 O transition toward 33 galactic ultracompact HII regions. Maser emission is detected toward 18 of these sources; two are new detections. High quality spectra are provided for all 18 sources. We discuss the detection rate of this survey and the correlation of various maser properties with other physical parameters. In addition, we report wide...
متن کاملThe 6 - GHz methanol multibeam maser catalogue II : Galactic longitudes 6 ◦ to 20 ◦
We present the second portion of an unbiased survey of the Galactic plane for 6668MHz methanol masers. This section of the survey spans the longitude range 6◦ to 20◦. We report the detection of 119 maser sources, of which 42 are new discoveries. The masers are tightly constrained to the Galactic plane, with only four outside a latitude range of ±1◦. This longitude region includes the brightest ...
