JWST/MIRI Observations of PAH Emission and Evolution in H II Regions of NGC 5457
Atul Kumar Singh, Rahul Kumar Anand, Shantanu Rastogi
Aims: To investigate the physical processing of PAHs in high-mass star-forming environments. This study aims to characterize how the PAH ionization fraction varies across different…
Probing Dust and PAH Chemistry in Evolved Carbon-Rich Nebulae through Optical and Infrared Observations
Rahul Kumar Anand, Atul Kumar Singh, Saurabh Sharma +2
This study presents optical and near-infrared photometric observations, alongside mid-infrared spectroscopic data from the ISO SWS instrument, to examine potential correlations bet…
Research on the Interstellar Medium and Star Formation in the Galaxy: An Indian Perspective
Bhaswati Mookerjea, Maheswar G., Kinsuk Acharyya +24
Although the star formation process has been studied for decades, many important aspects of the physics involved remain unsolved. Recent advancement of instrumentation in the infra…
Photometric and Kinematic study of the open cluster NGC 1027
Apara Tripathi, Neelam Panwar, Saurabh Sharma +2
We present photometric and kinematic analysis of an intermediate age open cluster NGC 1027 using and Gaia Early Data Release 3 (EDR3) data. Structural and fundamental p…
Study of vibrational spectra of polycyclic aromatic hydrocarbons with phenyl side group
Anju Maurya, Rashmi Singh, Shantanu Rastogi
Computational study of polycyclic aromatic hydrocarbons (PAHs) with phenyl side group substituted at different positions is reported. The infrared spectral variations due to the po…
A comparative study of the physical properties for a representative sample of Narrow and Broad-line Seyfert galaxies
Vivek Kumar Jha, Hum Chand, Vineet Ojha +2
We present a comparative study of the physical properties of a homogeneous sample of 144 Narrow line Seyfert 1 (NLSy1) and 117 Broad-line Seyfert 1 (BLSy1) galaxies. These two samp…
Accretion Disk Sizes from Continuum Reverberation Mapping of AGN Selected from the ZTF Survey
Vivek Kumar Jha, Ravi Joshi, Hum Chand +4
We present the accretion disk size estimates for a sample of 19 active galactic nuclei (AGN) using the optical , , and band light curves obtained from the Zwicky Transien…
