Dynamical Evolution of Four Old Galactic Open Clusters traced by their constituent stars with \textit{Gaia} DR3
Shanmugha Balan, Khushboo K Rao, Kaushar Vaidya +2
We investigate the evolutionary stages of four open clusters, Berkeley 39, Collinder 261, NGC 6819, and NGC 7789, of ages ranging from 1.6 -- 6 Gyr. These clusters have previously…
X-ray diagnostics of Cassiopeia A's "Green Monster": evidence for dense shocked circumstellar plasma
Jacco Vink, Manan Agarwal, Patrick Slane +4
The recent survey of the core-collapse supernova remnant Cassiopeia A (CasA) with the MIRI instrument on board the James Webb Space Telescope (JWST) revealed a large structure in t…
UOCS-XI. Study of blue straggler stars in open cluster NGC 7142 using UVIT/AstroSat
Anju Panthi, Kaushar Vaidya, Nagaraj Vernekar +3
We present a study of blue straggler stars (BSSs) of open cluster NGC 7142 using AstroSat/UVIT data and other archival data. Using a machine learning-based algorithm, ML-MOC, on Ga…
Determination of dynamical ages of open clusters through the A parameter -- II
Khushboo K. Rao, Kaushar Vaidya, Manan Agarwal +2
Blue straggler stars (BSS), one of the most massive members of star clusters, have been used for over a decade to investigate mass segregation and estimate the dynamical ages of gl…
Four years of Type Ia Supernovae Observed by TESS: Early Time Light Curve Shapes and Constraints on Companion Interaction Models
M. M. Fausnaugh, P. J. Vallely, M. A. Tucker +10
We present 307 Type Ia supernova (SN) light curves from the first four years of the TESS mission. We use this sample to characterize the shapes of the early time light curves, meas…
Applications of Deep Learning to physics workflows
Manan Agarwal, Jay Alameda, Jeroen Audenaert +65
Modern large-scale physics experiments create datasets with sizes and streaming rates that can exceed those from industry leaders such as Google Cloud and Netflix. Fully processing…
A EDR3 search for tidal tails in disintegrating open clusters
Souradeep Bhattacharya, Khushboo K. Rao, Manan Agarwal +2
We carry out a search for tidal tails in a sample of open clusters with known relatively elongated morphology. We identify the member stars of these clusters from the precise astro…
UOCS-VIII. UV Study of the open cluster NGC 2506 using ASTROSAT
Anju Panthi, Kaushar Vaidya, Vikrant Jadhav +4
We study an intermediate-age open cluster NGC 2506 using the \textit{ASTROSAT}/UVIT data and other archival data. We identified 2175 cluster members using a machine learning-based…
Characterization of hot populations of Melotte 66 open cluster using Swift/UVOT
K. K. Rao, K. Vaidya, M. Agarwal +3
Ultraviolet (UV) wavelength observations have made a significant contribution to our understanding of hot stellar populations of star clusters. Multi-wavelength spectral energy dis…
UOCS VII. Blue Straggler Populations of Open Cluster NGC 7789 with UVIT/AstroSat
Kaushar Vaidya, Anju Panthi, Manan Agarwal +4
NGC 7789 is a 1.6 Gyr old, populous open cluster located at 2000 pc. We characterize the blue straggler stars (BSS) of this cluster using the Ultraviolet (UV) data from…
Tidal tails in the disintegrating open cluster NGC 752
Souradeep Bhattacharya, Manan Agarwal, Khushboo K. Rao +1
We utilize the robust membership determination algorithm, ML-MOC, on the precise astrometric and deep photometric data from Gaia Early Data Release 3 within a region of radius 5$^{…
Determination of dynamical ages of open clusters through the A parameter -- I
Khushboo K. Rao, Kaushar Vaidya, Manan Agarwal +1
The sedimentation level of blue straggler stars (BSS) has been shown to be a great tool to investigate the dynamical states of globular clusters (GCs). The area enclosed between th…
ML-MOC: Machine Learning (kNN and GMM) based Membership Determination for Open Clusters
Manan Agarwal, Khushboo K. Rao, Kaushar Vaidya +1
The existing open cluster membership determination algorithms are either prior dependent on some known parameters of clusters or are not automatable to large samples of clusters. I…
Blue Straggler Populations of Seven Open Clusters with Gaia DR2
Kaushar Vaidya, Khushboo K. Rao, Manan Agarwal +1
Blue straggler stars (BSS) are well studied in globular clusters but their systematic study with secure membership determination is lacking in open clusters. We use Gaia DR2 data t…
