LIGHTS. Limitations of Far-Infrared Tracers for Galactic Cirrus Mitigation in the Era of Ultra-Deep Imaging
Ouldouz Kaboud, Ignacio Trujillo, Ignacio Ruiz Cejudo +18
Current and forthcoming deep optical imaging surveys are reaching surface brightness levels fainter than 30 mag/arcsec, where Galactic cirrus emission becomes a significant con…
How large can galaxies be? Ultra-deep imaging of IC 1101, the most extended known galaxy
Carlos Marrero-de la Rosa, Ignacio Trujillo, Ignacio Ruiz Cejudo +12
The maximum physical extent that galaxies can reach is poorly understood. In this regard, IC 1101, one of the most extended and massive galaxies known, provides a valuable opportun…
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…
The mysterious Globular Cluster population of MATLAS-2019
Sergio Guerra Arencibia, Mireia Montes, Giulia Golini +1
MATLAS-2019 (also known as NGC5846-UDG1) has attracted significant attention due to the ongoing debate surrounding its Globular Cluster (GC) population, with several studies addres…
Revisiting the structure of galactic disks with deep imaging
Samane Raji, Ignacio Trujillo, Fernando Buitrago +2
Thanks to new advances in astronomical imaging, we can now routinely explore disk galaxy profiles about two magnitudes deeper than the data available 20 years ago. In this regard,…
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…
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. 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 th…
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…
Exploring the nature of dark matter with the extreme galaxy AGC 114905
Pavel E. Mancera Piña, Giulia Golini, Ignacio Trujillo +1
AGC 114905 is a dwarf gas-rich ultra-diffuse galaxy seemingly in tension with the cold dark matter (CDM) model. Specifically, the galaxy appears to have an extremely low-density ha…
Ultra-deep imaging of NGC1052-DF2 and NGC1052-DF4 to unravel their origins
Giulia Golini, Mireia Montes, Eleazar R. Carrasco +2
A number of scenarios have been proposed to explain the low velocity dispersion (and hence possible absence of dark matter) of the low surface brightness galaxies NGC1052-DF2 and N…
Gnuastro: Estimating the Zero Point Magnitude in Astronomical Imaging
Sepideh Eskandarlou, Mohammad Akhlaghi, Raúl Infante-Sainz +6
Calibration of pixel values is a fundamental step for accurate measurements in astronomical imaging. In astronomical jargon this is known as estimating zero point magnitude. Here,…
An almost dark galaxy with the mass of the Small Magellanic Cloud
Mireia Montes, Ignacio Trujillo, Ananthan Karunakaran +9
Almost Dark Galaxies are objects that have eluded detection by traditional surveys such as the Sloan Digital Sky Survey (SDSS). The low surface brightness of these galaxies ((…
Introducing the LBT Imaging of Galactic Halos and Tidal Structures (LIGHTS) survey. A preview of the low surface brightness Universe to be unveiled by LSST
Ignacio Trujillo, Mauro D'Onofrio, Dennis Zaritsky +10
We present the first results of the LBT Imaging of Galaxy Haloes and Tidal Structures (LIGHTS) survey. LIGHTS is an ongoing observational campaign with the 2x8.4m Large Binocular T…
