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…
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 kinematic and structural study of young open clusters in the Milky Way Galaxy using Gaia DR3 catalogue
Harsha K. H., Annapurni Subramaniam, S. R. Dhanush +1
We aim to identify the cluster members, estimate cluster properties, study the dynamical state of the clusters as a function of mass, trace the existence of dynamical effects in ma…
AstroSat/UVIT Study of NGC 663: First detection of Be+sdOB systems in a young star cluster
Sneha Nedhath, Sharmila Rani, Annapurni Subramaniam +1
Be stars are rapidly rotating stars surrounded by a disc; however, the origin of these stars remains unclear. Mass and angular momentum transfer in close binaries account for the r…
UVIT Study of the Magellanic Clouds (U-SMAC). III. Hierarchical Star Formation in the Small Magellanic Cloud Regulated by Turbulence
Sipra Hota, Richard de Grijs, Annapurni Subramaniam
The Small Magellanic Cloud (SMC), a satellite galaxy of the Milky Way, is an irregular dwarf galaxy exhibiting evidence of recent and ongoing star formation. We performed a spatial…
Unraveling the kinematic and morphological evolution of the Small Magellanic Cloud
S. R. Dhanush, A. Subramaniam, S. Subramanian
We modeled the kinematics of the Small Magellanic Cloud (SMC) by analyzing the proper motion (PM) from Gaia DR3 of nine different stellar populations, which include young main sequ…
UVIT Study of the MAgellanic Clouds (U-SMAC) II. A Far-UV catalog of the Small Magellanic Cloud: Morphology and Kinematics of young stellar population
Sipra Hota, Annapurni Subramaniam, Prasanta K. Nayak +1
The Small Magellanic Cloud (SMC) is an irregular dwarf galaxy that has recently undergone an interaction with the Large Magellanic Cloud. The young massive stars in the SMC formed…
UVIT Study of the MAgellanic Clouds (U-SMAC) I. Recent star formation history and kinematics of the Shell region in the North-Eastern Small Magellanic Cloud
Sipra Hota, Annapurni Subramaniam, S. R. Dhanush +2
The interactions between the Magellanic Clouds significantly affect the shape and distribution of the young stellar population, particularly in the periphery of the Small Magellani…
A comprehensive kinematic model of the LMC disk from star clusters and field stars using Gaia DR3: Tracing the disk characteristics, rotation, bar, and the outliers
S. R. Dhanush, A. Subramaniam, S. Subramanian
The internal kinematics of the Large Magellanic Cloud (LMC) disk have been modeled by several studies using different tracers with varying coverage, resulting in a range of paramet…
Simultaneous FUV and NUV observations of T Tauri stars with UVIT/AstroSat: probing accretion process in young stars
Prasanta K. Nayak, Mayank Narang, P. Manoj +4
We present results from simultaneous FUV and NUV observations of T-Tauri stars (TTSs) in the Taurus molecular cloud with UVIT/AstroSat. This is the very first UVIT study of TTSs. F…
Spatio-temporal map of star clusters in the Magellanic Clouds using Gaia: Synchronized peaks and radial shrinkage of cluster formation
S. R. Dhanush, A. Subramaniam, Prasanta K. Nayak +1
We present a detailed view of cluster formation (CF) to trace the evolution and interaction history of the Magellanic Clouds (MCs) in the last 3.5 Gyr. Using the \textit{Gaia} DR3…
