The Infrared Glow of Galactic Outskirts: A New Window with NASIM

The outskirts of galaxies retain fossil records of their assembly history and are dominated by old stellar populations shaped by tidal interactions, accretion events, and environmental processes. Observing these low-surface-brightness (LSB) regions in the near-infrared (NIR), particularly in the $K_s$ band, is crucial...

Ultra-deep Imaging of the Starless Galaxy Candidate Cloud-9

We report the non-detection of stellar light associated with the dark galaxy candidate Cloud-9. Ultra-deep imaging obtained with HiPERCAM at the Gran Telescopio Canarias (GTC) reaches surface-brightness limits of 31.4 and 31.0 mag arcsec−2 in g and r, respectively, approximately ten times deeper than previous deep imag...
