Molecular line search toward the flaring 6.7-GHz methanol masers of G24.33+0.13 and G359.6-0.243: rare maser transitions detected
Tiege McCarthy, Gabor Orosz, Simon Ellingsen +8
We have performed a molecular line search toward the flaring 6.7-GHz masers G24.33+0.13 and G359.62-0.24 using the Australia Telescope Compact Array. We present spectra of the 6.7-…
Observations of 12.2 GHz methanol masers towards northern high-mass protostellar objects
M. Durjasz, M. Szymczak, P. Wolak +1
Context. Class II methanol masers at 6.7 and 12.2 GHz occur close to high-mass young stellar objects (HMYSOs). When they are observed simultaneously, such studies may contribute to…
A search for the OH 6035 MHz line in high-mass star-forming regions
M. Szymczak, P. Wolak, A. Bartkiewicz +2
The excited states of OH masers detected in the environment of high-mass young stellar objects (HMYSOs) are important for improving our understanding of the physical conditions of…
Long-term multi-frequency maser observations of the intermediate-mass young stellar object G107.298+5.639
Mateusz Olech, Marian Szymczak, Paweł Wolak +2
Periodic flares of maser emission are thought to be induced either by variations of the seed photon flux in young binary systems or the pump rate regulated by stellar and accretion…
Detection statistics of the RadioAstron AGN survey
Y. Y. Kovalev, N. S. Kardashev, K. V. Sokolovsky +57
The largest Key Science Program of the RadioAstron space VLBI mission is a survey of active galactic nuclei (AGN). The main goal of the survey is to measure and study the brightnes…
6.7 GHz variability characteristics of new periodic methanol maser sources
Mateusz Olech, Marian Szymczak, Paweł Wolak +2
Discovery of periodic maser emission was an unexpected result from monitoring observations of methanol transitions in high-mass young stellar objects. We report on the detection of…
