ABSTRACT G+ 0.693-0.03 is a quiescent molecular cloud located within the Sagittarius B2
(Sgr B2) star-forming complex. Recent spectral surveys have shown that it represents one of …

Class II methanol (CH 3 OH) masers are amongst the clearest signposts of recent high-mass
star formation (HMSF). A complete catalogue outlines the distribution of star formation in the …

We have identified 453 compact dense cores in 3 mm continuum emission maps in the
ALMA Three-millimetre Observations of Massive Star-forming regions survey, and compiled …

Context. Methanol masers of Class I (collisionally pumped) and Class II (radiatively pumped)
have been studied in great detail in our Galaxy in a variety of astrophysical environments …

Context. Class I methanol masers are known to be associated with shocked outflow regions
around massive protostars, indicating a possible link between the maser properties and …

In this paper, we have conducted an investigation focused on a segment of the Spitzer mid-
infrared bubble N59, specifically referred to as R1 within our study. Situated in the inner …

We use spectra and maps of the J= 1− 0 and J= 2− 1 DCO+, DCN, DNC, lines, and 111−
101 ortho-and para-NH2D lines, obtained with the Institut de Radioastronomie Millimétrique …

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 …

We present a study of the correlation between 22 GHz water maser emission and far-
infrared/submillimeter (IR/sub-mm) sources. The generalized linear model (GLM) is used to …

Infrared dark clouds (IRDCs) represent the earliest stage of high-mass star formation and
host molecular cores at different states of activity from quiet state without any IR-signature of …
