Unveiling the roles of thermal and nonthermal processes in the ISM & IGM structure formation and evolution of galaxies with SKAO

Fatemeh S. Tabatabaei, Masoumeh Ghasemi-Nodehi, Mark T. Sargent +10

Investigating the thermal and nonthermal processes in the interstellar medium (ISM) and intergalactic medium (IGM) is vital to understanding the evolution of galaxies over cosmic t…

Impact of Anomalous Microwave Emission (AME) on Radio Spectral Energy Distributions: SKA Observations of Galaxies Near and Far

Ilsang Yoon, Eric Murphy, Caroline Bot +1

Radio continuum emission powered by the thermal bremsstrahlung process is a clean, dust-free tracer of star formation in galaxies. However, the existence of anomalous microwave emi…

The Dual Nature of GHZ9: Coexisting Active Galactic Nuclei and Star Formation Activity in a Remote X-ray Source at z = 10.145

Lorenzo Napolitano, Marco Castellano, Laura Pentericci +33

We present James Webb Space Telescope (JWST)/NIRSpec PRISM spectroscopic characterization of GHZ9 at z= 10.145 0.010, currently the most distant source detected by the Chandr…

Searching for Dark Galaxies with HI detection from the Arecibo Legacy Fast ALFA (ALFALFA) survey

Minseong Kwon, Ho Seong Hwang, Brian R. Kent +3

We present a catalog of 142 dark galaxy candidates in a region covered by the Arecibo Legacy Fast ALFA (ALFALFA) survey. We start with 344 ALFALFA HI sources without optical counte…

The SUPERCOLD-CGM survey: II. [\ion{C}{1}] emission and the physical conditions of cold gas in Enormous Ly nebulae at

Jianan Li, Bjorn H. C. Emonts, Zheng Cai +13

We report ALMA and ACA observations of atomic carbon ([\ion{C}{1}]) and dust continuum in 10 Enormous Ly Nebulae hosting ultra-luminous Type-I QSOs at , as pa…

Not just PAH: why galaxies turn red in the Near-Infrared

Benedetta Vulcani, Tommaso Treu, Matthew Malkan +11

We measure the spectral properties of a sample of 20 galaxies at z~0.35 selected for having surprisingly red JWST/NIRCAM F200W-F444W colors. 19 galaxies were observed with JWST/NIR…
