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 (NUV…
Two Epochs of VLBI Observations of 8 KISSR Seyfert & LINER Galaxies: Suggestions of Fast and Filamentary Outflows
Preeti Kharb, Anderson Caproni, Salmoli Ghosh +4
We present here the results from a second epoch of phase-referenced VLBA observations of 8 Seyfert and LINER galaxies from the KISSR sample. These sources were chosen based on the…
Dwarf-Dwarf interactions and their influence on star formation : Insights from post-merger galaxies
Rakshit Chauhan, Smitha Subramanian, Deepak A. Kudari +2
Dwarf galaxies dominate the galaxy population across all redshifts, and majority of mergers are expected to occur between them. However, the impact of dwarf-dwarf mergers on star f…
A pilot method to determine the high mass end of the Stellar Initial Mass Function in galaxies using UVIT, H-MUSE observations and applied to NGC628
S Amrutha, Mousumi Das
We present a pilot method to estimate the high-mass initial mass function (IMF) across the arm, interarm, and spur regions in galaxies and apply it to NGC 628. We extracted star-fo…
Tracing Hierarchical Star Formation out to Kiloparsec Scales in Nearby Spiral Galaxies with UVIT
Gairola Shashank, Smitha Subramanian, Sreedevi M. +5
Molecular clouds fragment under the action of supersonic turbulence & gravity which results in a scale-free hierarchical distribution of star formation (SF) within galaxies. Recent…
First Search for High-Energy Neutrino Emission from Galaxy Mergers
Subhadip Bouri, Priyank Parashari, Mousumi Das +1
The exact sources of high-energy neutrinos detected by the IceCube neutrino observatory still remain a mystery. For the first time, this work explores the hypothesis that galaxy me…
A Comparative Study of Star Forming Dwarf Galaxies using the UVIT
S Amrutha, Mousumi Das, Jyoti Yadav
We present a Far-Ultraviolet (FUV) study of sixteen star-forming dwarf galaxies (SFDGs) using the Ultraviolet Imaging Telescope (UVIT). Morphologically, SFDGs are classified as dwa…
Relativistic Jet Motion in the Radio-quiet LINER Galaxy KISSR872
Preeti Kharb, Eric G. Blackman, Eric Clausen-Brown +5
We report superluminal jet motion with an apparent speed of in the radio-quiet (RQ) low ionisation nuclear emission line region (LINER) galaxy, KISSR87…
The Search for Binary Black holes in Seyferts with Double Peaked Emission Lines
P. Kharb, M. Das, S. Subramanian +1
We discuss results from very long baseline interferometry (VLBI) observations of two Seyfert galaxies with double peaked emission lines in their SDSS optical spectra. Such AGN are…
VLBI Imaging of the Double Peaked Emission Line Seyfert KISSR1494
Preeti Kharb, Mousumi Das, Zsolt Paragi +2
We present here the results from dual-frequency phase-referenced VLBI observations of the Seyfert galaxy KISSR1494, which exhibits double peaked emission lines in its SDSS spectrum…
