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…
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…
Optical constraints on the coldest metal-poor population
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. MartÃn +10
The coldest metal-poor population made of T and Y dwarfs are archaeological tracers of our Galaxy because they are very old and have kept the pristine material. The optical propert…
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…
LIGHTS. Survey Overview and a Search for Low Surface Brightness Satellite Galaxies
Dennis Zaritsky, Giulia Golini, Richard Donnerstein +12
We present an overview of the LIGHTS (LBT Imaging of Galactic Halos and Tidal Structures) survey, which currently includes 25 nearby galaxies that are on average 1 mag faint…
