Detections of Compact Radio Continuum toward Methanol Maser Rings Using the VLA
Anna Bartkiewicz, Olga Bayandina, Alberto Sanna +5
High-mass protostars are deeply embedded in dust inside their natal cores and are not easily detectable. However, maser emission at centimeter wavelengths, owing to its high bright…
A search for the favored hyperfine transition of a 6.7 GHz methanol maser line
A. Kobak, G. Surcis, A. Bartkiewicz +2
The polarized emission of astrophysical masers, especially OH and methanol lines, is an effective tool to study the magnetic field in high-mass star-forming regions. The magnetic f…
Discovery of synchronized periodic variability of methanol maser features in G26.598-0.024
P. Wolak, M. Szymczak, A. Kobak +5
Aims. We report the discovery of periodic maser variability of an unusual pattern in the high-mass young stellar object G26.598-0.024. Methods. A ten-year monitoring of the 6.7 GHz…
Physical conditions around high-mass young star-forming objects via simultaneous observations of excited OH and methanol masers
A. Kobak, A. Bartkiewicz, K. L. J. Rygl +3
Astrophysical masers are widely used in star formation studies. In particular, they are valuable in investigations of high-mass star-forming regions that are difficult to observe a…
Superradiance and Periodic 6.7 GHz Methanol Flaring in G22.356+0.066
T. Rashidi, V. Anari, A. Bartkiewicz +3
We present a comprehensive analysis of the periodic flares observed in the 6.7 GHz methanol transition in G22.356+0.066, utilizing the Maxwell-Bloch equations (MBEs) as a framework…
Proper motion study of the 6.7 GHz methanol maser rings. I. A sample of sources with little variation
A. Bartkiewicz, A. Sanna, M. Szymczak +5
Methanol masers at 6.7~GHz are well-known signposts of high-mass star-forming regions. [...] We aim to understand the origin of the ring-like structures outlined by methanol maser…
