Valentin Mauerhofer, Jérémy Blaizot, Thibault Garel +11

Low-ionisation state (LIS) absorption lines, such as SiII 1526, are widely used to trace the properties of the interstellar medium (ISM) in galaxies. These lines provide crucial in…

The dominance of turbulence over magnetism in the formation of massive star cluster seeds

Junhao Liu, Patricio Sanhueza, Piyali Saha +32

High-mass stars form in protoclusters, where gravo-magnetic processes shape collapsing clouds and clumps to be elongated preferentially perpendicular to magnetic (B) fields. Yet it…

Molecular gas and star formation in central rings across nearby galaxies

Damian R. Gleis, Sophia K. Stuber, Eva Schinnerer +20

Nearby galaxies exhibit a variety of structures, including central rings, similar to the MW Central Molecular Zone (CMZ). These rings are common in barred galaxies and can be gas-r…

Archaeological investigation of galaxies' evolutionary history in the cosmic middle ages

Anna R. Gallazzi, Stefano Zibetti, Mark Sargent +14

The cosmic Middle Ages, spanning the last 8-10 Gyr of the Universe, is a critical period in which massive early-formed systems coexist with global star formation quenching in less…

KURVS: chemical properties from multiple strong line calibrations for star-forming galaxies at $z \sim 1.5$

Zefeng Li, Ugnė Dudzevičiūtė, Annagrazia Puglisi +13

Gas-phase oxygen abundance (metallicity) properties can be constrained through emission line analyses, and are of great importance to investigate galaxy evolution histories. We pre…

JWST reveals extended stellar disks for ALMA-bright dusty star-forming galaxies in the Spiderweb protocluster

Y. H. Zhang, H. Dannerbauer, J. M. Pérez-Martínez +14

We present JWST/NIRCam imaging of dusty star-forming galaxies (DSFGs) detected by Atacama Large Millimeter/submillimeter Array (ALMA) in the Spiderweb protocluster at $z = 2.16$ . We…

VENUS: When Red meets Blue -- A multiply imaged Little Red Dot with an apparent blue companion behind the galaxy cluster Abell 383

Miriam Golubchik, Lukas J. Furtak, Joseph F. V. Allingham +50

We report the discovery of a doubly-imaged Little Red Dot (LRD) candidate behind the galaxy cluster Abell 383, which we dub A383-LRD1. Initially classified as a dropout galaxy in H…
