Investigating the Young Stellar Populations and Hierarchies in Nearby Galaxies with the UVIT. III. Evidence for a Largest Scale of Correlated Stellar Structures and a Non-universal Fractal Dimension
Gairola Shashank, Smitha Subramanian, Shyam H. Menon +5
Scale-free turbulent motions, gravitational collapse and galactic dynamics govern galactic-scale, hierarchical organization of star formation (SF) within galaxies. Past studies sug…
Cloud Scale Star Formation and Gas Scaling Relations in the Milky Way
Alphesunny Sarkar, Tapas Baug, Ariful Hoque +2
We investigate cloud-scale star formation in the Milky Way using a sample of 45 molecular clouds (sizes of pc) in the inner Galactic plane, spanning heliocentric distances…
Investigating the young stellar populations and hierarchies in nearby galaxies with the UVIT. II. Presenting the properties of ~25,000 UV-detected star-forming clumps
Gairola Shashank, Smitha Subramanian, Chayan Mondal +2
Studying young stellar populations within galaxies can help refine our understanding of recent star formation in galaxies and their evolution. With this motivation, we present a ca…
A FUV-optical approach for studying hierarchical star formation in nearby galaxies with UVIT
Sanal Ananthu, Gairola Shashank, Smitha Subramanian +4
Young star-forming clumps (SFCs) emit strongly in the ultraviolet (UV), making UV imaging ideal for detecting them. The Ultraviolet Imaging Telescope (UVIT) onboard AstroSat, with…
A first systematic study of [OIII] 88m at : two luminous oxygen lines and a powerful ionized outflow in the first 600 million years
Hiddo S. B. Algera, John R. Weaver, Tom J. L. C. Bakx +35
We present deep ALMA Band 7 observations of the [OIII] m line and underlying dust continuum emission in four UV-bright, gravitationally lensed (magnification ), JW…
The Stellar Morphology & Size of X-ray-selected Active Galactic Nuclei Host Galaxies Revealed by JWST
Bovornpratch Vijarnwannaluk, Zhen-Kai Gao, Wei-Hao Wang +19
We investigate the stellar shape and size-mass relationship of X-ray selected Active Galactic Nuclei (AGN) host galaxies using the high-angular resolution and deep sensitivity in t…
Unveiling a Population of Strong Galaxy-Galaxy Lensed Faint Dusty Star-Forming Galaxies
Ting-Kai Yang, Chian-Chou Chen, Zhen-Kai Gao +10
The measurements of the number density of galaxy-galaxy strong lenses can be used to put statistical constraints on the foreground mass distributions. Dusty galaxies uncovered in s…
Discovery of a kinematically distinct component in the central region of the collisional ring galaxy AM0644-741
Chayan Mondal, Sudhanshu Barway
We present the discovery of a peculiar central stellar structure in the collisional ring galaxy AM0644-741 using HST imaging and MUSE integral field unit (IFU) data. We identified…
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…
Effect of low-mass galaxy interactions on their star formation
Smitha Subramanian, Chayan Mondal, Venu Kalari
According to the cold dark matter model of galaxy formation, the hierarchical assembly process is scale-free and interactions between galaxies in all mass ranges are expected.…
Unravelling the Post-Collision Properties of the Cartwheel Galaxy: A MUSE Exploration of its Bar and Inner Region
Chayan Mondal, Sudhanshu Barway
Aims: To investigate the characteristics of the bar and inner disk in the collisional ring galaxy Cartwheel. Methods: We used the Integral Field Unit (IFU) observations with Multi-…
