Spatial correlations of PAH, UV, Hα emission and IMF–PAH variations in the star-forming complexes of NGC 628

S Amrutha, D. Rigopoulou, Mousumi Das, Jyoti Yadav

ABSTRACT We examine the spatial correlation of emission from polycyclic aromatic hydrocarbons (PAH) (3.3, 7.7, and 11.3 $\mathrm{\mu m}$) with the far-ultraviolet (FUV), near-ultraviolet (NUV), and H$\alpha$ emission from star-forming complexes (SFCs) in different regions of NGC 628. We use the James …

Unveiling the kinematics of a central region in the triple-AGN host NGC 7733-7734 interacting group

S. Keshri, Sudhanshu Barway, Mousumi Das, Jyoti Yadav et autres

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 within the central region and stellar bars of both galaxies. We performed a comprehensive analysis using archival …

The morphology and kinematics of the galaxy group AM 1054-325: A MUSE perspective

Jyoti Yadav, Vikrant V. Jadhav

Galaxy interactions in groups can lead to intense starbursts and the activation of active galactic nuclei (AGNs). The stripped gas from the outer disk can lead to star-forming clumps along the tidal tails or sometimes tidal dwarf galaxies. We investigate the impact …

A comparative study of star-forming dwarf galaxies using the UVIT

S Amrutha, Mousumi Das, Jyoti Yadav

ABSTRACT We present a far-ultraviolet (FUV) study of 16 star-forming dwarf galaxies (SFDGs) using the Ultra Violet Imaging Telescope. Morphologically, SFDGs are classified as dwarf spirals, dwarf irregulars, and blue compact dwarfs (BCDs). We extracted the star-forming complexes (SFCs) from the sample …

Study of star formation in dual nuclei galaxies using UVIT observations

K. Rubinur, Mousumi Das, Preeti Kharb, Jyoti Yadav et autres

ABSTRACT We have used the Ultraviolet Imaging Telescope (UVIT) aboard AstroSat to study star formation in a sample of nine dual nuclei galaxies with separations ⪅ 11 kpc, which is an expected outcome of galaxy mergers. To minimize the contribution of active …

An FUV and optical study of star formation in closely interacting galaxies: star-forming rings, tidal arms, and nuclear outflows

Jyoti Yadav, Mousumi Das, Sudhanshu Barway, F. Combes

ABSTRACT We present a study of the morphology of star formation and the associated nuclear activity in a sample of eight closely interacting southern galaxies, which are in different stages of interaction, starting with nearly merged nuclei that have one prominent bulge …

Hidden in plain sight: UVIT and MUSE discovery of a large, diffuse star-forming galaxy

Jyoti Yadav, Mousumi Das, Sudhanshu Barway, F. Combes

We report the discovery of a nearby large, diffuse galaxy that shows star formation using Ultra Violet Imaging Telescope (UVIT) far-UV observations and archival optical data from Multi-Unit Spectroscopic Explorer (MUSE), Dark Energy Camera Legacy Survey, and InfraRed Survey Facility near-infrared observations. …

A triple active galactic nucleus in the NGC 7733–7734 merging group

Jyoti Yadav, Mousumi Das, Sudhanshu Barway, F. Combes

Context. Galaxy interactions and mergers can lead to supermassive black hole (SMBH) binaries, which become active galactic nucleus (AGN) pairs when the SMBHs start accreting mass. If there is a third galaxy involved in the interaction, then a triple-AGN system can form. …
