An Attenuation Bump at z=9.3: Probing Dust Diversity at Cosmic Dawn
Giulia Rodighiero, Santiago Álvarez-Córdoba, Michele Catone +46
We report the identification of a UV attenuation bump in the Black Pearl, a galaxy at a spectroscopic redshift of 9.3335 observed with JWST/NIRSpec as part of the ZENITH and EMBER…
An empirical derivation of the average dust attenuation law at 2<z<7
Giulia Rodighiero, Gaia Edes Esposito, Daniela Calzetti +12
Dust attenuation affects galaxy SEDs and introduces uncertainties in star formation rates, stellar masses, and metallicities. Direct spectroscopic constraints at early cosmic epoch…
The Role of Spiral Arms in Galaxies II: Similarities Amid Diversity
Bingqing Sun, Daniela Calzetti, Andrew J. Battisti
The role of spiral arms in galaxies -- whether they enhance star formation efficiency or primarily act as material gatherers -- remains an open question. Observational studies have…
H Morphologies of Star Clusters in 16 LEGUS Galaxies: Constraints on HII region evolution timescales
Stephen Hannon, Janice C. Lee, Bradley C. Whitmore +14
The analysis of star cluster ages in tandem with the morphology of their HII regions can provide insight into the processes that clear a cluster's natal gas, as well as the accurac…
