Spatial Correlations of PAH, UV, H Emission and IMF - PAH Variations in the Star-Forming Complexes of NGC 628
S Amrutha, Dimitra Rigopoulou, Mousumi Das +1
We examine the spatial correlation of emission from polycyclic aromatic hydrocarbons (PAH) (3.3 m, 7.7 m, and 11.3 m) with the far-ultraviolet (FUV), near-ultraviolet (…
Star Formation Beyond the Optical Disk : The Low-Density Outskirts of NGC2090
Jyoti Yadav, Mousumi Das, S Amrutha +1
We present a far-ultraviolet (FUV) analysis of the star-forming complexes (SFCs) in the nearby spiral galaxy NGC\,2090, based on observations from the Ultraviolet Imaging Telescope…
Search for Faint Lone Double-Peaked H Lines as IMBH Signatures in the MUSE Deep Field
Jyoti Yadav, Jorge Sánchez Almeida, Casiana Muñoz Tuñón +1
Double-peaked H emission profiles can serve as potential signatures of accreting intermediate-mass black holes (IMBHs), particularly those residing outside galactic nuclei. Suc…
Environment and Gas Fraction in Type-2 AGN versus Non-AGN Galaxies
Jyoti Yadav, Jong-Hak Woo, Ashraf Ayubinia
We investigate the environmental parameters and gas fraction (f) properties of type~2 AGN and non-AGN galaxies, utilizing a large sample of galaxies from SDSS DR7 with z $\…
Unveiling the kinematics of a central region in the triple AGN host NGC 7733-7734 interacting group
Saili Keshri, Sudhanshu Barway, Mousumi Das +2
We present a detailed study of the interacting triple active galactic nuclear system NGC 7733-34, focusing on stellar kinematics, ionised gas characteristics and star formation wit…
