The Growth of Dust in Galaxies in the First Billion Years with Applications to Blue Monsters
Desika Narayanan, Paul Torrey, Daniel Stark +9
A combination of JWST observations at z~12-14 and ALMA observations of extremely dust-rich systems at z~6 has demonstrated that dust grows extremely fast in the early Universe, wit…
Investigating the role of mergers in galaxy assembly in the early Universe (z > 5)
A. Calabrò, A. Calabrò, L. Pentericci +21
Galaxy mergers play a crucial role in shaping the morphology, the star formation, and the mass growth of galaxies across cosmic time. While mergers have been extensively investigat…
MIRI spectrophotometry of GN-z11: Detection and nature of an optical red continuum component
A. Crespo Gómez, L. Colina, P. G. Pérez-González +16
We present new MIRI F560W, F770W and F1000W imaging of GN-z11, extending the previous rest-frame coverage from 0.38 to 0.86m. We report significant detections (14) in the F…
A spectroscopically confirmed, strongly lensed, metal-poor Type II supernova at z = 5.13
David A. Coulter, Conor Larison, Justin D. R. Pierel +88
Observing supernovae (SNe) in the early Universe (z > 3) provides a window into how both galaxies and individual stars have evolved over cosmic time, yet a detailed study of high-r…
HELM's deep: Highly Extincted Low-Mass galaxies seen by JWST
L. Bisigello, G. Gandolfi, A. Grazian +25
The dust content of star-forming galaxies is generally positively correlated with their stellar mass. However, some recent JWST studies have shown the existence of a population of…
Density modulated star formation efficiency: implications for the observed abundance of ultra-violet luminous galaxies at z>10
Rachel S. Somerville, L. Y. Aaron Yung, Lachlan Lancaster +3
The number density of UV luminous galaxies discovered by the James Webb Space Telescope at ultra high redshift () is higher, and declines much more slowly with increa…
