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…
The stellar distribution in ultra-faint dwarf galaxies suggests deviations from the collision-less cold dark matter paradigm
Jorge Sanchez Almeida, Ignacio Trujillo, Angel R. Plastino
Unraveling the nature of dark matter (DM) stands as a primary objective in modern physics. Here we present evidence suggesting deviations from the collisionless Cold DM (CDM) parad…
Application of the Eddington inversion method to constrain the dark matter halo of galaxies using only observed surface brightness profiles
Jorge Sanchez Almeida, Angel R. Plastino, Ignacio Trujillo
*** Context: The halos of low-mass galaxies may allow us to constrain the nature of dark matter (DM), but the kinematic measurements to diagnose the required properties are technic…
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…
Deep HST imaging favors the bulgeless edge-on galaxy explanation for the hypothetical stellar wake created by a runaway supermassive black hole
Mireia Montes, Jorge Sánchez Almeida, Ignacio Trujillo
A long linear structure recently discovered could be the stellar wake produced by the passage of a runaway supermassive black hole (SMBH) or, alternatively, a bulgeless edge-on gal…
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…
