ALMA2040: The High-Redshift Circumgalactic Medium. Imaging the fueling and feedback of galaxies in the early universe
Kirsty M. Butler, Justin Spilker, Seiji Fujimoto +23

Resolving the Assembly of Disk Galaxies from the Epoch of Reionisation to Cosmic Noon
Melanie Kaasinen, Mahsa Kohandel, Francesca Rizzo +45

The dawn of the first galaxies
Livia Vallini, Tanio Diaz Santos, Belen Alcalde Pampliega +56
Understanding how the first galaxies assembled their stellar mass at cosmic dawn is a central frontier of modern astrophysics. JWST has now revealed an unexpected population of ult…

We present constraints on the dust emission and attenuation properties of galaxies across 0<z<7 using JWST imaging from the COSMOS-Web Survey combined with deep FIR/(sub)millimeter…
A Post-starburst Galaxy Undergoing Ram-pressure Stripping at Redshift 3.06
Mingyu Li, Zheng Cai, Bjorn H. C. Emonts +16
Understanding how galaxies ignite and extinguish their star formation remains a cornerstone question in modern astrophysics. Recent JWST surveys have revealed an overabundance of m…
The ALPINE-CRISTAL-JWST Survey: Chemical Abundance Comparison Between the ISM and CGM of Main-Sequence Galaxies at z=4-6
Wuji Wang, Andreas L. Faisst, Kyle Finner +37
Gaseous halos around galaxies play an important role in galaxy evolution. The exchange of metals from the interstellar medium (ISM) to the circumgalactic medium (CGM) are caused by…
The ionised interstellar medium of DSFGs revealed by JWST/NIRSpec and ALMA: Super-solar metallicity, low ionisation parameters and, typical electron densities
Steven Gillman, Kei Ito, Francesco Valentino +25
We present a detailed study of near-infrared (2-4m) JWST/NIRSpec spectra of 48 high-redshift () galaxies detected with ALMA at . From a multi-wa…
Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity

We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…
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…

Ori D. Fox, Armin Rest, Justin D. R. Pierel +48
Transient astronomy in the early Universe (z > 2) remains largely unexplored, lying beyond the rest-frame optical spectroscopic reach of most current observatories. Yet this regime…
ALMA and JWST Identification of Faint Dusty Star-Forming Galaxies up to z~8
