Andromeda's tenuous veil: A likely Milky Way nebula projected toward M31
A. Lumbreras-Calle, J. A. Fernández-Ontiveros, R. Infante-Sainz +10
A large, faint nebula was unexpectedly discovered near M31 using narrowband [O III] images. Its apparent size and the lack of a clear counterpart at other wavelengths make it uniqu…
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: measuring radial profiles from images
Raúl Infante-Sainz, Mohammad Akhlaghi, Sepideh Eskandarlou
Radial profiles play a crucial role in the analysis and interpretation of astronomical data, facilitating the extraction of spatial information. However, highly customizable (for d…
Discovery of a large and faint nebula at the Triangulum galaxy
Aleix Roig, Raúl Infante-Sainz, Judith Ardèvol
We report the discovery of a previously uncatalogued arch-shaped filamentary nebula at the outer part of the Triangulum galaxy (M33) centred at R.A. = 1h34m25s, Dec = +30d20m17s (I…
Gnuastro: visualizing the full dynamic range in color images
Raúl Infante-Sainz, Mohammad Akhlaghi
Color plays a crucial role in the visualization, interpretation, and analysis of multi-wavelength astronomical images. However, generating color images that accurately represent th…
