We report the first sub-arcsecond VLA imaging of 6 GHz continuum, methanol maser, and
excited-state hydroxyl maser emission toward the massive protostellar cluster NGC 6334I …

In this study we present 18 24 GHz and high-angular-resolution (0.5 arcsec) radio
wavelength Australia Telescope Compact Array follow-up observations towards a sample of …

Formation processes of high-mass stars have been long-standing issues in astronomy and
astrophysics. This is mainly because of major difficulties in observational studies such as a …

Methanol masers at 6.7 GHz are the brightest of class II methanol masers and have been
found exclusively towards massive star-forming regions. These masers can thus be used as …

We investigated the nature of protostellar objects in G358. 46− 0.39 and their gas kinematics
using ALMA data, with the aim of understanding the ongoing star formation activities in the …

We present results of a survey of 14 star-forming regions from the Perseus spiral armin CS
(2–1) and 13 CO (1–0) lines with the Onsala Space Observatory 20 m telescope. Maps of 10 …

Understanding the structure and associated dynamics of the inner 4-kpc region of the Milky
Way is very challenging because of high obscuration at optical wavelengths and its impact …

Accurate positions (to sub-arcsecond accuracy) of 25 GHz class I methanol maser emission
were obtained for 28 sources in active star forming regions in the Southern Hemisphere …

A star is a large self-luminous cosmic ball of gas, primarily hydrogen, that is kept together by
its own gravity and shines by radiation produced by internal energy sources. The hydrostatic …

We investigated the parameters of a Massive Galactic Dense Core (MGDC) G328. 2353-
0.5481 detected within a sample ATLASGAL selected infrared quiet massive clumps at 0.9 …
