Star Clusters in the Ultraviolet
Annapurni Subramaniam, Samyaday Choudhury, Richard de Grijs +5
Ultraviolet (UV) observations provide a powerful window into the hot and evolved stellar populations that shape the structure, evolution and integrated light of star clusters. Beca…
An excess of luminous white dwarfs in the peculiar Galactic globular cluster NGC 2808
Laksh Gupta, Samyaday Choudhury, Annalisa Calamida +2
We study the white dwarf (WD) cooling sequence of the Galactic Globular Cluster (GGC) NGC 2808 by using deep near-UV data from the Hubble Space Telescope and theoretical models, to…
Globular Cluster UVIT legacy Survey (GlobUleS) III. Omega Centauri in Far-Ultraviolet
Deepthi S. Prabhu, Annapurni Subramaniam, Snehalata Sahu +21
We present the first comprehensive study of the most massive globular cluster Omega Centauri in the far-ultraviolet (FUV) extending from the center to ~ 28% of the tidal radius usi…
The intrinsic reddening of the Magellanic Clouds as traced by background galaxies -- III. The Large Magellanic Cloud
Cameron P. M. Bell, Maria-Rosa L. Cioni, Angus H. Wright +15
We present a map of the total intrinsic reddening across ~90 deg of the Large Magellanic Cloud (LMC) derived using optical (ugriz) and near-infrared (IR; YJKs) spectral energ…
Globular Clusters UVIT Legacy Survey (GlobULeS) I. FUV-optical Color-Magnitude Diagrams for Eight Globular Clusters
Snehalata Sahu, Annapurni Subramaniam, Gaurav Singh +22
We present the first results of eight Globular Clusters (GCs) from the AstroSat/UVIT Legacy Survey program GlobULeS based on the observations carried out in two FUV filters (F148W…
The VMC survey -- XLVII. Turbulence-Controlled Hierarchical Star Formation in the Large Magellanic Cloud
Amy E. Miller, Maria-Rosa L. Cioni, Richard de Grijs +9
We perform a statistical clustering analysis of upper main-sequence stars in the Large Magellanic Cloud (LMC) using data from the Visible and Infrared Survey Telescope for Astronom…
The VMC survey -- XLIV: Mapping metallicity trends in the Large Magellanic Cloud using near-infrared passbands
Samyaday Choudhury, Richard de Grijs, Kenji Bekki +9
We have derived high-spatial-resolution metallicity maps covering 105~deg across the Large Magellanic Cloud (LMC) using near-infrared passbands from the VISTA Survey of t…
The VMC Survey -- XL. Three-dimensional structure of the Small Magellanic Cloud as derived from red clump stars
B. L. Tatton, J. Th. van Loon, M. -R. L. Cioni +12
Galaxy interactions distort the distribution of baryonic matter and can affect star formation. The nearby Magellanic Clouds are a prime example of an ongoing galaxy interaction pro…
The intrinsic reddening of the Magellanic Clouds as traced by background galaxies -- II. The Small Magellanic Cloud
Cameron P. M. Bell, Maria-Rosa L. Cioni, A. H. Wright +23
We present a map of the total intrinsic reddening across ~34 deg of the Small Magellanic Cloud (SMC) derived using optical () and near-infrared (IR; …

Samyaday Choudhury, Richard de Grijs, Stefano Rubele +7
We have derived high spatial resolution metallicity maps covering 42 deg across the Small Magellanic Cloud (SMC) in an attempt to understand its metallicity distribution…
The VMC Survey -- XXXV. Model fitting of LMC Cepheid light curves
Fabio Ragosta, Marcella Marconi, Roberto Molinaro +10
We present the results of the light curve model fitting technique applied to optical and near-infrared photometric data for a sample of 18 Classical Cepheids (11 fundamentals and 7…
