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…
J-PLUS: Turning Off the Bright Stars
Sepideh Eskandarlou, Mohammad Akhlaghi, Johan H. Knapen +23
Photometric surveys require precise point spread function (PSF) characterization, as it varies across filters and is crucial for accurate photometry and low surface brightness (LSB…
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…
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,…
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…
