Large scale map of millimeter wavelength hydrogen radio recombination lines around a young massive star cluster
(IOP Publishing Ltd, 2017)
We report the first map of large-scale (10 pc in length) emission of millimeter-wavelength hydrogen recombination lines (mm-RRLs) toward the giant H II region around the W43-Main young massive star cluster (YMC). Our mm-RRL ...
Characterizing the radio continuum nature of sources in the massive star-forming region W75N (B)
(Wiley Blackwell Publishing, Inc, 2020-06)
The massive star-forming region W75N (B) is thought to host a cluster of massive protostars (VLA 1, VLA 2, and VLA 3) undergoing different evolutionary stages. In this work, we present radio continuum data with the highest ...
Radio and X-ray study of two multi-shell supernova remnants: Kes 79 and G352.7-0.1
(EDP Sciences, 2009-12)
Aims. We investigate two multi-shell galactic supernova remnants (SNRs), Kes 79, and G352.7−0.1, to understand the causes of this morphology. Methods. The research was carried out based on new and reprocessed archival VLA ...
GSH 91.5+2-114: A large H i shell in the outer part of the Galaxy
(EDP Sciences, 2011-01)
GSH 91.5 + 2 − 114 is a large H i shell located in the outer Galaxy at a kinematic distance of about 15 kpc. It was first identified in the Canadian Galactic Plane Survey (CGPS) by Pineault et al. (2002, ASP Conf. Ser., ...
A search for ionized jets towards massive young stellar objects
(Oxford University Press, 2016)
Radio continuum observations using the Australia telescope compact array at 5.5, 9.0, 17.0 and 22.8 GHz have detected free-free emission associated with 45 of 49 massive young stellar objects and H ii regions. Of these, ...
The low-frequency radio emission and spectrum of the extended SNR W44: new VLA observations at 74 and 324 MHz
(EDP Sciences, 2007-12)
Aims. We present new Very Large Array (VLA) radio images at 74 and 324 MHz of the SNR W44. The VLA images, obtained with unprecedented angular resolution and sensitivity for such low frequencies (HPBW 37 at 74 MHz, and 13 ...
Cosmic evolution of molecular gas mass density from an empirical relationship between L1.4 GHz and L' CO

Chemical Diagnostics of the Massive Star Cluster-forming Cloud G33.92+0.11. II. HDCS and DCN
(Institute of Physics Publishing, 2018)
The central region of the massive star-forming cloud G33.92+0.11 was investigated with the emission from the
deuterated species HDCS and DCN observed at sub-arcsecond angular resolution (∼0 7) using ALMA. HDCS
shows a ...
Radio emission from interstellar shocks: Young type Ia supernova remnants and the case of N 103B in the Large Magellanic Cloud
(Springer, 2019-11)
We investigate young type Ia supernova remnants (SNRs) in our Galaxy and neighbouring galaxies in order to understand their properties and early stage of their evolution. Here we present a radio continuum study based on ...
