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…
Sh2-138: Physical environment around a small cluster of massive stars
T. Baug, D. K. Ojha, L. K. Dewangan +4
We present a multi-wavelength study of the Sh2-138, a Galactic compact H II region. The data comprise of optical and near-infrared (NIR) photometric and spectroscopic observations…
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…
