The 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 کاملThe 6-GHz methanol multibeam maser catalogue IV: Galactic longitudes 186◦ to 330◦ including the Orion–Monoceros region
We present the fourth portion of a Galactic Plane survey of methanol masers at 6668MHz, spanning the longitude range 186◦ to 330◦. We report 207 maser detections, 89 new to the survey. This completes the southern sky part of the Methanol Multibeam survey and includes a large proportion of new sources, 43%. We also include results from blind observations of the Orion–Monoceros star forming regio...
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 ...
متن کاملA general catalogue of 6.7-GHz methanol masers⋆ I: data
Methanol masers are often detected in regions of intense star formation. Several studies in the last decade indicate that they may even be the earliest signpost of a high-mass star-forming region. Their powerful emission make them very good candidates for observations using both single–dish telescopes and interferometers, the latter allows detailed structural and dynamical studies of these obje...
متن کاملExcited-state hydroxyl maser catalogue from the methanol multibeam survey – I. Positions and variability
Wepresent the results of the first complete unbaised survey of theGalactic plane for 6035-MHz excited-state hydroxyl (ex-OH) masers undertaken as part of the methanol multibeam (MMB) survey. These observations cover the Galactic longitude ranges 186◦ < l < 60◦ including the Galactic Centre. We report the detection of 127 ex-OH masers within the survey region, 47 being new sources. The positions...
