H <span>ii</span> regions and supernova remnants associated with molecular clouds: a pilot study with the SARAO MeerKAT Galactic Plane Survey Open
Massive stars (mass >8 $\mathrm{M_\odot }$) release vast amounts of energy into the interstellar medium through their stellar winds, photoionizing radiation, and supernova explosions. These processes may compress nearby regions, triggering…

The NIKA2 cosmological legacy survey at 2 mm: catalogs, colors, redshift distributions, and implications for deep surveys Open
Millimeter galaxy surveys are particularly effective in detecting dusty star-forming galaxies at high redshift. While such observations are typically conducted at ~1mm, studies suggest that 2mm may be better suited for selecting sources at…
