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…
Lyman-alpha Radiation Pressure in Dense Star Clusters: Implications for Star Formation and Winds at Cosmic Dawn
Shyam H Menon, Aaron Smith
Observations with the JWST in lensed fields have revealed that galaxies at cosmic dawn may concentrate their star formation in highly dense, compact, star clusters. The high column…
A cosmological framework for stellar collisions at high redshift in proto-globular clusters, nuclear star clusters, and Little Red Dots
Claire E. Williams, Smadar Naoz, Sanaea C. Rose +8
Observations and cosmological simulations indicate that the early Universe hosted numerous compact, high-density stellar systems, where close encounters and physical collisions bet…
Blue Monsters and Dusty Descendants: Reconciling UV and IR Emission from Galaxies from z=7, up to z= 14
Laura Sommovigo, Lachlan Lancaster, Shyam H. Menon +3
Recent JWST observations reveal massive, UV-bright galaxies at with little apparent dust attenuation, whereas ALMA detections at show similarly massive system…
Radiation magnetohydrodynamics simulations of Population III star formation during the Epoch of Reionization
Lisanne van Veenen, Piyush Sharda, Serena Viti +1
Cosmological simulations find that pockets of star-forming gas could remain pristine up until the Epoch of Reionization (EoR) due to the inhomogeneous nature of metal mixing and en…
