Low-redshift Lyman Continuum Survey: Radio continuum properties of low- Lyman continuum emitters
Omkar Bait, Sanchayeeta Borthakur, Daniel Schaerer +20
Sources that leak Lyman-continuum (LyC) photons and lead to the reionisation of the universe are intensely studied using multiple observing facilities. Recently, the Low-redshift L…
NOEMA observations of GN-z11: Constraining Neutral Interstellar Medium and Dust Formation in the Heart of Cosmic Reionization at
Y. Fudamoto, P. A. Oesch, F. Walter +17
We present results of dust continuum and [CII] emission line observations of a remarkably UV-luminous () galaxy at : GN-z11. Using the…
Inferring the presence of very massive stars in local star-forming regions
Fabrice Martins, Daniel Schaerer, Rui Marques-Chaves +1
We present a study aiming at detecting VMS in local star-forming region from the imprint they leave on the integrated UV and optical light. We analyzed a sample of 27 star-forming…
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…
Reionization and the ISM/Stellar Origins with JWST and ALMA (RIOJA): The core of the highest redshift galaxy overdensity at confirmed by NIRSpec/JWST
Takuya Hashimoto, Javier Álvarez-Márquez, Yoshinobu Fudamoto +20
The protoclusters in the epoch of reionization, traced by galaxies overdensity regions, are ideal laboratories for studying the process of stellar assembly and cosmic reionization.…
N-enhancement in GN-z11: First evidence for supermassive stars nucleosynthesis in proto-globular clusters-like conditions at high redshift ?
C. Charbonnel, D. Schaerer, N. Prantzos +5
Unusually high N/O abundance ratios were recently reported for a very compact, intensively star-forming object GN-z11 at from JWST/NIRSpec observations. We present an empi…
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 Low-Redshift Lyman Continuum Survey: Optically Thin and Thick Mg II Lines as Probes of Lyman Continuum Escape
Xinfeng Xu, Alaina Henry, Timothy Heckman +14
The Mg II 2796, 2803 doublet has been suggested to be a useful indirect indicator for the escape of Ly-alpha and Lyman continuum (LyC) photons in local star-forming galaxies. Howev…
Clues on the presence and segregation of very massive stars in the Sunburst Lyman-continuum cluster at z=2.37
U. Mestric, E. Vanzella, A. Upadhyaya +15
We report the identification of very massive stars (VMS; mass \,\msun) that may be segregated in the center of the young massive star cluster at =2.37 hosted in the lense…
