The spatially resolved star formation history of the dwarf spiral galaxy NGC 5474
G. Bortolini, M. Cignoni, E. Sacchi +16
We study the resolved stellar populations and derive the star formation history of NGC 5474, a peculiar star-forming dwarf galaxy at a distance of Mpc, using Hubble Space…
Universal Upper End of the Stellar Initial Mass Function in the Young and Compact LEGUS clusters
Dooseok Escher Jung, Daniela Calzetti, Matteo Messa +21
We investigate the variation in the upper end of stellar initial mass function (uIMF) in 375 young and compact star clusters in five nearby galaxies within Mpc. All the yo…
Resolved Kennicutt-Schmidt law in two strongly lensed star-forming galaxies at redshift 1
David Nagy, Miroslava Dessauges-Zavadsky, Matteo Messa +4
We study the star formation rate (SFR) versus molecular gas mass () scaling relation from hundreds to thousands parsec scales in two strongly lensed galaxies at red…
Extreme N-emitters at high-redshift: signatures of supermassive stars and globular cluster or black hole formation in action?
R. Marques-Chaves, D. Schaerer, A. Kuruvanthodi +9
[Abridged] Using the JWST/NIRSpec observations from CEERS we found an extreme N-emitter, CEERS-1019 at z=8.6782 showing intense NIV and NIII emission. From the observed rest-UV and…
Constraining the LyC escape fraction from LEGUS star clusters with SIGNALS HII region observations: A pilot study of NGC 628
J. W. Teh, K. Grasha, M. R. Krumholz +23
The ionising radiation of young and massive stars is a crucial form of stellar feedback. Most ionising (Lyman-continuum; LyC, ) photons are absorbed close to the stars tha…
An extremely metal poor star complex in the reionization era: Approaching Population III stars with JWST
E. Vanzella, F. Loiacono, P. Bergamini +31
We present JWST/NIRSpec integral field spectroscopy (IFS) of a lensed Population III candidate stellar complex (dubbed Lensed And Pristine 1, LAP1), with a lensing-corrected stella…
Search strategies for supermassive stars in young clusters and application to nearby galaxies
A. Kuruvanthodi, D. Schaerer, M. Messa +4
Supermassive stars (SMS) with masses , formed by runaway collisions in young, massive, and dense star clusters have been invoked as a possible soluti…
The Lyman Reference Sample XIV: Lyman imaging of 45 low redshift star-forming galaxies and inferences on global emission
Jens Melinder, Göran Östlin, Matthew Hayes +18
We present Ly imaging of 45 low redshift star-forming galaxies observed with the Hubble Space Telescope. The galaxies have been selected to have moderate to high star formation…
Dust Buried Compact Sources in the Dwarf Galaxy NGC 4449
Daniela Calzetti, Sean T. Linden, Timothy McQuaid +10
Multi-wavelength images from the Hubble Space Telescope covering the wavelength range 0.27-1.6 m show that the central area of the nearby dwarf galaxy NGC4449 contains several t…
Molecular gas cloud properties at revealed by the superb angular resolution achieved with ALMA and gravitational lensing
Miroslava Dessauges-Zavadsky, Johan Richard, Françoise Combes +6
Current observations favour that the massive ultraviolet-bright clumps with a median stellar mass of , ubiquitously observed in galaxies, are star-…
