Probing the Low Radio Frequency Emission in PG Quasars with the uGMRT -- II
Sanna Gulati, Silpa Sasikumar, Preeti Kharb +3
We present results from uGMRT 685 MHz observations of 87 QSOs belonging to the Palomar Green (PG) quasar sample with . Radio emission is detected in all sources except for 3…
Connection between steep radio spectral slopes and dust extinction in QSOs: evidence for outflow-driven shocks in dusty QSO
V. A. Fawcett, C. M. Harrison, D. M. Alexander +9
Recent studies have found a striking positive correlation between the amount of dust obscuration and enhanced radio emission in quasi-stellar objects (QSOs). However, what causes t…
Massive star-formation in the hub-filament system of RCW 117
Arun Seshadri, S. Vig, S. K. Ghosh +1
We present a multiwavelength investigation of the hub-filament system RCW 117 (IRAS 17059-4132), which shows intricate filamentary features in the far-infrared, mapped using Hersch…
The disintegrating old open cluster Czernik 3
Saurabh Sharma, Arpan Ghosh, D. K. Ojha +6
We have performed a detailed analysis of the Czernik 3 (Cz3) open cluster by using deep near-infrared photometry taken with TIRCAM2 on 3.6m Devasthal optical telescope along with t…
NGC 7538 : Multiwavelength Study of Stellar Cluster Regions associated with IRS 1-3 and IRS 9 sources
K. K. Mallick, D. K. Ojha, M. Tamura +7
We present deep and high-resolution (FWHM ~ 0.4 arcsec) near-infrared (NIR) imaging observations of the NGC 7538 IRS 1-3 region (in JHK bands), and IRS 9 region (in HK bands) using…
A Multi-Wavelength High Resolution Study of the S255 Star Forming Region. General structure and kinematics
I. Zinchenko, S. -Y. Liu, Y. -N. Su +4
We present observational data for two main components (S255IR and S255N) of the S255 high mass star forming region in continuum and molecular lines obtained at 1.3 mm and 1.1 mm wi…
