ARRAKIHS: The observability of tidally stripped satellites in a Milky Way-like halo
Abram Pérez-Herrero, Y. Revaz, S. Roca-Fàbrega +34
Deep imaging surveys are revealing increasing numbers of low surface brightness stellar streams around Milky Way-like galaxies. These streams trace the orbital evolution and intern…
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-PAS: unprecedented precision in stellar populations of diffuse tidal features
Sepideh Eskandarlou, Mohammad Akhlaghi, Francisco Arizo-Borillo +38
Galaxies frequently interact with nearby systems, a process that can significantly alter their morphology and star formation activity. However, spectroscopic studies of their faint…
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…
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…
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 ((…
The truncation of the disk of NGC 4565: Detected up to z=4 kpc, with star formation, and affected by the warp
Cristina Martinez-Lombilla, Raul Infante-Sainz, Felipe Jimenez-Ibarra +5
Context: The hierarchical model of galaxy formation suggests that galaxies are continuously growing. However, our position inside the Milky Way prevents us from studying the disk e…
Galaxy and Mass Assembly (GAMA): Extended Intra-Group Light in a group at from deep Hyper-Suprime Cam images
Cristina Martinez-Lombilla, Sarah Brough, Mireia Montes +7
We present a pilot study to assess the potential of Hyper Suprime-Cam Public Data Release 2 (HSC-PDR2) images for the analysis of extended faint structures within groups of galaxie…
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…
A disk and no signatures of tidal distortion in the galaxy "lacking" dark matter NGC 1052-DF2
Mireia Montes, Ignacio Trujillo, Raúl Infante-Sainz +2
Using ultra-deep imaging ( mag/arcsec; 3, 10"x10"), we probed the surroundings of the first galaxy "lacking" dark matter KKS2000[04] (NGC 1052-DF2). Signs of tid…
The galaxy "missing dark matter" NGC1052-DF4 is undergoing tidal disruption
Mireia Montes, Raúl Infante-Sainz, Alberto Madrigal-Aguado +4
The existence of long-lived galaxies lacking dark matter represents a challenge to our understanding of how galaxies form. Here, we present evidence that explains the lack of dark…
