The Extended Mapping Obscuration to Reionization with ALMA (Ex-MORA) Survey: A Molecular Gas Line Search

V. Catán, J. González-López, M. Aravena +9

Current investigations of cold gas in the interstellar medium face selection biases, as optical/near-infrared surveys favor massive, low-obscuration galaxies and miss gas-rich pass…

Primordial Rotating Disk Composed of 15 Dense Star-Forming Clumps at Cosmic Dawn

S. Fujimoto, M. Ouchi, K. Kohno +43

Early galaxy formation, initiated by the dark matter and gas assembly, evolves through frequent mergers and feedback processes into dynamically hot, chaotic structures. In contrast…

ALMA Lensing Cluster Survey: Physical characterization of near-infrared-dark intrinsically faint ALMA sources at z=2-4

Akiyoshi Tsujita, Kotaro Kohno, Shuo Huang +33

We present results from Atacama Large Millimeter/submillimeter Array (ALMA) spectral line-scan observations at 3-mm and 2-mm bands of three near-infrared-dark (NIR-dark) galaxies b…

A hidden active galactic nucleus powering bright [O III] nebulae in a protocluster at revealed by JWST

M. Solimano, J. González-López, M. Aravena +48

Galaxy protoclusters are sites of rapid growth, with a high density of massive galaxies driving elevated rates of star formation and accretion onto supermassive black holes. Here,…

Molecular gas budget of strongly magnified low-mass star-forming galaxies at cosmic noon

V. Catán, J. González-López, M. Solimano +8

This study aims to investigate the molecular gas content of strongly magnified low-mass star-forming galaxies around the cosmic noon period () through observations of CO em…
