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…

On the clumpy nature of super-early galaxies

A. Ferrara, B. Das, M. Kohandel +2

JWST has revealed that galaxies during the Epoch of Reionization are composed of compact stellar clumps spanning more than two orders of magnitude in mass and size. We present an a…

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 . We combine new high-resolution ALMA [O III]88m o…

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…

Strong nebular HeII emission induced by He ionizing photons escaping through the clumpy winds of massive stars

Arpita Roy, Mark R. Krumholz, Stefania Salvadori +8

The origin of nebular HeII-emission in both local and high-redshift galaxies remains an unsolved problem. Various theories have been proposed to explain it, including HeII-ionizati…

Stellar halos tracing the assembly of ultra-faint dwarf galaxies

Lapo Querci, Andrea Pallottini, Lorenzo Branca +1

[Abridged]Ultra-faint dwarfs (UFDs) are expected to be the relics of the earliest galaxies forming in the Universe. Observations show the presence of a stellar halo around them, wh…

Emulating the interstellar medium chemistry with neural operators

Lorenzo Branca, Andrea Pallottini

Galaxy formation and evolution critically depend on understanding the complex photo-chemical processes that govern the evolution and thermodynamics of the InterStellar Medium (ISM)…

Neural networks: solving the chemistry of the interstellar medium

Lorenzo Branca, Andrea Pallottini

Non-equilibrium chemistry is a key process in the study of the InterStellar Medium (ISM), in particular the formation of molecular clouds and thus stars. However, computationally i…

The interstellar medium of high-redshift galaxies: Gathering clues from C III] and [C II] lines

Vladan Markov, Stefano Carniani, Livia Vallini +5

A tight relation between [C II] line luminosity and the star formation rate (SFR) has been observed for local galaxies. At high redshift (z > 5), galaxies instead deviate downwards…

Shaping the structure of a GMC with radiation and winds

D. Decataldo, A. Lupi, A. Ferrara +2

We study the effect of stellar feedback (photodissociation/ionization, radiation pressure and winds) on the evolution of a Giant Molecular Cloud (GMC), by means of a 3D radiative t…
