From stardust to interstellar grain growth in the first galaxies: a cosmological transition in dust evolution near z ~ 8.9
Denis Burgarella, Tom J. L. C. Bakx, Raffaella Schneider +7
When and how did dust begin to shape galaxies? Motivated by the identification of an apparent redshift break in galaxy dust masses, suggesting substantially lower dust masses at $z…
The applicability of the JAGB method for measuring the distance of galaxies subject to different metal enrichment rates
Claudio Gavetti, Paolo Ventura, Flavia Dell'Agli +4
The JAGB method has been proposed in recent years as a possible distance indicator for galaxies in the Local Group and beyond. However, the nature of the stars populating the J reg…
Metal Mayhem at : Diversity and Evolution of Gas-Phase Metallicity Gradients
Maria Koller, Roberto Maiolino, Hannah Übler +16
We present a JWST/NIRSpec-IFU study of metallicity gradients in seven low-metallicity systems at . The main sample spans stellar masses of $\rm \log(M_*/M_{\odot}) \sim…
UV background fluctuations traced by metal ions at
L. Graziani, A. Maselli, U. Maio
Here we investigate how LyC-opaque systems present in the intergalactic medium at can distort the spectral shape of a uniform UV background (UVB) through radiative tran…
