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

Galaxies do not form in isolation, but rather as part of a wider interconnected web mediated at their interface by an extended gaseous atmosphere - the Circum-Galactic Medium (CGM)…

Resolving the Assembly of Disk Galaxies from the Epoch of Reionisation to Cosmic Noon

Melanie Kaasinen, Mahsa Kohandel, Francesca Rizzo +45

Most of the mass and angular momentum of today's disk galaxies assembled at $z > 1$ . Yet, it remains unclear how these galaxies acquired their gas, how their baryons and dark matter…

What fuels the growth of stars and black holes in galaxies through cosmic time? The physics and chemistry of the interstellar medium in distant galaxies

Leindert A. Boogaard, Manuel Aravena, Matus Rybak +25

The interplay between the baryonic matter in galaxies (gas, dust, stars) has a fundamental role in our understanding of galaxy formation and evolution through cosmic time. The (sub…

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…

ALMA2040: Understanding the Early Assembly of Galaxies - The Formation of Star-Forming Clumps and their Role in Shaping Galaxy Evolution

Anita Zanella, Andreas L. Faisst, Rodrigo Herrera-Camus +25

Astrophysics seeks to explain how galaxies form and evolve through the interplay of stars, gas, and dust. Giant molecular clouds (GMCs), the main reservoirs and sites of star forma…

The birth and fate of stellar clumps in super-early galaxies

B. Das, A. Ferrara, A. Pallottini +2

(Abridged) JWST has revealed extremely compact stellar clumps in galaxies at z>6, but their formation mechanism and subsequent evolution remain uncertain. We investigate whether su…

Multi-tracer exploration of molecular gas in main sequence galaxies at z~4.5

M. Dessauges-Zavadsky, M. Béthermin, M. Ginolfi +15

Molecular gas masses in high-z galaxies are inferred from indirect tracers, whose respective reliability remains poorly constrained. In particular, the bright [CII] 158 $μ$ m line is…

REBELS-25: multi-phase morphology and kinematics at z = 7.31

Lucie E. Rowland, Hiddo S. B. Algera, Jacqueline Hodge +23

We present a spatially resolved, multi-wavelength study of the massive, star-forming galaxy REBELS-25 at a redshift of $z = 7.31$ . We combine new high-resolution ALMA [O III]88 $μ$ m o…

No Blue without Red: Evolutionary Properties of Super-Early Galaxies

A. Ferrara, G. Rodighiero, S. Carniani +3

The discovery of numerous luminous, super-early galaxies at $z > 10$ by JWST has revealed a striking diversity in their ultraviolet (UV) properties, ranging from extremely blue, dust…

Intense and extended CIII] emission suggests a strong outflow in JADES-GS-z14-0

Stefano Carniani, Peter Jakobsen, Giacomo Venturi +31

JWST has revealed an overabundance of very bright, blue galaxies at z>10, raising fundamental questions about how star formation and feedback operate at Cosmic Dawn. We present new…

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 ALPINE-CRISTAL-JWST Survey: NIRSpec IFU Data Processing and Spatially-resolved Views of Chemical Enrichment in Normal Galaxies at z=4-6

Seiji Fujimoto, Andreas L. Faisst, Akiyoshi Tsujita +37

We present a statistical study of spatially resolved chemical enrichment in 18 main-sequence galaxies at $z = 4$ --6, observed with \jwst/NIRSpec IFU as part of the ALPINE-CRISTAL-\jw…

The ALPINE-CRISTAL-JWST Survey: JWST/IFU Optical Observations for 18 Main-Sequence Galaxies at z=4-6

A. L. Faisst, S. Fujimoto, A. Tsujita +80

To fully characterize the formation and evolution of galaxies, we need to observe their stars, gas, and dust on resolved spatial scales. We present the ALPINE-CRISTAL-JWST survey,…

The ALPINE-CRISTAL-JWST Survey: The Fast Metal Enrichment of Massive Galaxies at z~5

Andreas L. Faisst, Lun-Jun Liu, Yohan Dubois +54

We present the stellar mass-metallicity relation (MZR) and mass-metallicity-star formation relation ("fundamental metallicity relation"; FMR) of 18 massive (log(M/Msun) = 9.5 - 11)…

Lessons Learned from Studying H $α$ Galaxy Kinematics with Mock JWST/NIRSpec IFU Observations at $z > 6$

Siân Phillips, Francesca Rizzo, Mahsa Kohandel +2

Galaxies with a disk morphology have been established at $z > 9$ with the James Webb Space Telescope (JWST). However, confirming their disky nature requires studying their gas kine…
