  • A search for the OH 6035 MHz line in high-mass star-forming regions 
    Szymczak, Marian; Wolak, Paweł; Bartkiewicz, Anna; Aramowicz, Mirosława; Durjasz, Michał (EDP Sciences, 2020)
    Context. 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 these objects and also provide ...
  • European VLBI Network imaging of 6.7 GHz methanol masers 
    Bartkiewicz, Anna; Szymczak, Marian; van Langevelde, Huib Jan (EDP Sciences, 2016)
    Context. Methanol masers at 6.7 GHz are well known tracers of high-mass star-forming regions. However, their origin is still not clearly understood. Aims. We aimed to determine the morphology and velocity structure for a ...
  • Giant burst of methanol maser in S255IR-NIRS3 
    Szymczak, Marian; Olech, Mateusz; Wolak, Paweł; Gerard, Eric; Bartkiewicz, Anna (EDP Sciences, 2018)
    Context.High-mass young stellar objects (HMYSOs) can undergo accretion episodes that strongly affect the star evolution, the dynamics of the disk, and its chemical evolution. Recently reported ...
  • The nature of the methanol maser ring G23.657–00.127 II. Expansion of the maser structure 
    Bartkiewicz, Anna; Sanna, Alberto; Szymczak, Marian; Moscadelli, Luca; van Langevelde, Huib Jan; Wolak, Paweł (2020-05)
    Context. Ring-like distributions of the 6.7 GHz methanol maser spots at milliarcsecond scales represent a family of molecular structures of unknown origin associated with high-mass young stellar objects. Aims: We aim to ...
