Molecular inventory of a young eruptive star's environment -- Case study of the classical FU Orionis star V1057 Cyg
Zs. M. Szabó, A. Belloche, K. M. Menten +6
Studying accretion-driven episodic outbursts in YSOs is key to understanding the later stages of star and planet formation. FU Orionis-type objects form a YSO subclass, distinguish…

Hyperfine structure of the methanol molecule as traced by Class I methanol masers
I. I. Agafonova, O. S. Bayandina, Y. Gong +9
We present results on simultaneous observations of Class~I methanol masers at 25, 36, and 44 GHz towards 22 Galactic targets carried out with the Effelsberg 100-m telescope. The st…

Discovery of widespread non-metastable ammonia masers in the Milky Way
Y. T. Yan, C. Henkel, K. M. Menten +8
We present the results of a search for ammonia maser emission in 119 Galactic high-mass star-forming regions (HMSFRs) known to host 22 GHz HO maser emission. Our survey has led…
