  • 6.7 GHz variability characteristics of new periodic methanol maser sources 
    Olech, Mateusz; Szymczak, Marian; Wolak, Paweł; Sarniak, Rafał; Bartkiewicz, Anna (Monthly Notices of the Royal Astronomical Society, 2019-04-01)
    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 five new periodic sources from a monitoring ...
  • A Giant Water Maser Flare in the Galactic Source IRAS 18316-0602 
    Volvach, L. N.; Volvach, A. E.; Larinov, M. G.; MacLeod, G. C.; van den Heever, S. P.; Wolak, P; Olech, Mateusz; Ipanov, A. V.; Ivanov, D. V.; Mikhailov, A.G.; Melnikov, A.E.; Menten, K.; Belloche, A.; Weiss, A.; Mazumdar, P.; Schuller, F. (Astronomy Reports, 2019-01-01)
    The results of long-term monitoring of the Galactic maser source IRAS 18316-0602 (G25.65+1.05) in the water-vapor line at frequency f = 22.235 GHz (6_16-5_23 transitioin) carried out on the 22-m Simeiz, 26-m HartRAO, and ...
  • Long-term multi-frequency maser observations of the intermediate-mass young stellar object G107.298+5.639 
    Olech, Mateusz; Szymczak, Marian; Wolak, Paweł; Gérard, Eric; Bartkiewicz, Anna (Astronomy & Astrophysics, 2020-02-01)
    Context: 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 luminosities. Aims: We seek to ...
  • Monitoring observations of 6.7 GHz methanol masers 
    Szymczak, Marian; Olech, Mateusz; Sarniak, Rafał; Wolak, Paweł; Bartkiewicz, Anna (Oxford University Press, 2018-02)
    We report results of 6.7 GHz methanol maser monitoring of 139 star-forming sites with theTorun 32 m radio telescope from June 2009 to February 2013. The targets were observedat least once a month, with higher ...
