An important phenomenon in a pulsing AGB (Asymptotic Giant Branch) star is the variability of its circumstellar envelope. The study of stimulated radiation called SiO maser (microwave amplification by stimulated emission of radiation) in the inner ed

We investigated flux variability of 22 GHz water masers in W49 N, which have been observed for three epochs in the early year of 2017 using KaVA. We used angular resolution and Doppler velocity conditions to specify the identical maser features in ea

As a part of the mega-project, known as “Radio Astronomy Network and Geodesy for Development (RANGD)” by National Astronomical Research Institute of Thailand (NARIT), the fully steerable 40m Thai National Radio Telescope (TNRT) is under construct

The 22-GHz Water masers in the W49N star-forming region are one of the richest and most luminous sources in our Galaxy, at the distance of 11.11 kpc. Very Long Baseline Interferometric (VLBI) observations allow us to study both physics of these maser

We initiated a long-term with short-intervals monitoring project toward 442 CH3OH masers at 6.7 GHz (Dec > -30 deg) using Hitachi 32-m radio telescope of Japan in Dec 2012. Our observations have been carried out daily, monitoring a spectrum of each s

This study was aimed to make the neutral hydrogen (HI) mapping and rotation curve of the Milky Way at galactic longitude 0° to 90° in the galactic plane by using the 4.5 m Small Radio Telescope (SRT) of National Astronomical Research Institute of T

We surveyed the neutral hydrogen (HI) at 21 cm by using the 4.5m Thai Small Radio Telescope (SRT) of the National Research Institute of Thailand (NARIT) during January–March 2019. The main aim of this project is for doing the distribution maps of H

Solar radio bursts are important phenomena for studying solar activities such as flares and coronal mass ejections (CMEs). A worldwide network is ∼ 90 stations, known as, e-CALLISTO, has been developed such purpose. This CALLISTO spectrometer was i

We present preliminary results from OH ground state phase referenced observations carried out with the Multi Element Radio Linked Interferometer Network (MERLIN) and e-MERLIN towards the massive star forming region W49A. There are three active SFRs w
