Highly-ionized gas in lensed z = 6.027 Little Red Dot seen through [OIII] 88m with ALMA

Kirsten K. Knudsen, Johan Richard, Mathilde Jauzac +8

Determining the physical properties of galaxies during the first billion years after the big bang is key to understanding both early galaxy evolution and how galaxies contributed t…

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…

Inefficient dust production in a massive, metal-rich galaxy at uncovered by JWST and ALMA

Kasper E. Heintz, Darach Watson, Francesco Valentino +17

Recent observations have revealed a remarkably rapid buildup of cosmic dust in the interstellar medium (ISM) of high redshift galaxies, with complex dust compositions and large abu…

Early galaxy evolution: The complex interstellar medium distribution of the z~7 galaxy A1689-zD1

Kirsten K. Knudsen, Darach Watson, Johan Richard +12

We observed the gravitationally lensed () galaxy A1689-zD1 at in bands 3, 6, and 8 of the Atacama Large Millimeter/submillimeter Array. These high-resolut…

JWST+ALMA reveal the ISM kinematics and stellar structure of MAMBO-9, a merging pair of DSFGs in an overdense environment at

Hollis B. Akins, Caitlin M. Casey, Jaclyn B. Champagne +14

We present high-resolution ALMA [CII] 158 micron observations and JWST/NIRCam+MIRI imaging of MAMBO-9, a pair of optically-dark, dusty star-forming galaxies at . MAMBO-9 is…

The ALMA-CRISTAL survey: weak evidence for star-formation driven outflows in main-sequence galaxies

Jack E. Birkin, Justin S. Spilker, Rodrigo Herrera-Camus +23

There is a broad consensus from theory that stellar feedback in galaxies at high redshifts is essential to their evolution, alongside conflicting evidence in the observational lite…
