Augmenting the power of time-delay cosmography in lens galaxy clusters by probing their member galaxies I. Type Ia supernovae
A. Acebron, S. Schuldt, C. Grillo +9
We present a simple and promising new method to measure the expansion rate and the geometry of the universe that combines observations related to the time delays between the multip…
UV-continuum slopes of individual clumps and their evolution
A. Bolamperti, A. Zanella, U. Meštrić +11
We study the ultraviolet (UV) continuum slope of a sample of 166 clumps, individual star-forming regions observed in high redshift galaxies. They are hosted by 67 galaxies with…
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…
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…
