LIGHTS. The Thin Encircling Stellar Stream of NGC 3938

Dennis Zaritsky, Jacob Nibauer, Giulia Golini +17

We present a stellar stream found in images of the nearby, nearly face-on, late-type galaxy, NGC 3938 obtained for the LBT Imaging of Galactic Halos and Tidal Structures (LIGHTS) s…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: A Low Surface Brightness Science Case

Mireia Montes, Ignacio Trujillo, David Martínez Delgado +27

The Extragalactic Low Surface Brightness (LSB, mag/arcsec) Universe represents a crucial, yet largely unseen, frontier in modern astrophysics. This faint realm…

LIGHTS. A robust technique to identify galaxy edges

Giulia Golini, Ignacio Trujillo, Dennis Zaritsky +19

The LIGHTS survey is imaging galaxies at a depth and spatial resolution comparable to what the Legacy Survey of Space and Time (LSST) will produce in 10 years (i.e., 31 mag/a…

LIGHTS. The extended point spread functions of the LIGHTS survey at the LBT

Nafise Sedighi, Zahra Sharbaf, Ignacio Trujillo +13

With the arrival of the next generation of ultra-deep optical imaging surveys reaching 30 mag/arcsec (3; 10"10"), the removal of scattered light due to…

UV LIGHTS. New tools for revealing the low surface brightness regime in the ultraviolet

Ignacio Ruiz Cejudo, Ignacio Trujillo, Giulia Golini +16

Ultra-deep optical surveys have reached unprecedented depths, facilitating the study of faint galactic structures. However, the ultraviolet bands, crucial for stellar population st…
