The Rogue One: A Dark Matter-Dominated Dwarf in the Trail of Dark Matter-Deficient Galaxies
Daniel Vaz, Arsen Levitskiy, Duncan Forbes +6
We present the first measurement of the stellar velocity dispersion of LEDA 4014647, a compact dwarf galaxy spatially aligned with the NGC 1052 trail, a linear chain of dark matter…
The MUSE-Faint survey V. The binary fraction of Leo T
Daniel Vaz, Jarle Brinchmann, Sebastian Kamann +3
The Leo T dwarf galaxy, the faintest and least massive galaxy known to have recent star formation (), exhibits a high dynamical mass-to-light ratio based on its stellar…
The radial acceleration relation at the EDGE of galaxy formation: testing its universality in low-mass dwarf galaxies
Mariana P. Júlio, Justin I. Read, Marcel S. Pawlowski +6
A tight correlation between the baryonic and observed acceleration of galaxies has been reported over a wide range of mass () - the Radi…
The CHIMERA Survey: The first CO detection in Leo T, the lowest mass known galaxy still hosting cold molecular gas
Vicente Villanueva, Matías Blaña, Alberto D. Bolatto +13
We report the first CO detection in Leo T, representing the most extreme observation of carbon monoxide molecules in the lowest stellar mass gas-rich dwarf galaxy ($\sim…
Leo T Dissected with the MUSE-Faint Survey
Daniel Vaz, Jarle Brinchmann, The MUSE Collaboration
Leo T is the lowest mass galaxy known to contain neutral gas and to show signs of recent star formation, which makes it a valuable laboratory for studying the nature of gas and sta…
The MUSE-Faint survey. IV. Dissecting Leo T, a gas-rich relic with recent star formation
Daniel Vaz, Jarle Brinchmann, Sebastiaan L. Zoutendijk +6
Leo T () is both the faintest and the least massive galaxy known to contain neutral gas and to display signs of recent star formation. We analyse photometry and stellar…
The MUSE-Faint survey. III. Constraining scalar field dark matter with Antlia B
Mariana P. Júlio, Jarle Brinchmann, Sebastiaan L. Zoutendijk +7
Aims. We use the stellar line-of-sight velocities of Antlia B (Ant B), a faint dwarf galaxy in the NGC 3109 association, to derive constraints on the fundamental properties of scal…
Robust bounds on ALP dark matter from dwarf spheroidal galaxies in the optical MUSE-Faint survey
Elisa Todarello, Marco Regis, Javier Reynoso-Cordova +5
Nearby dwarf spheroidal galaxies are ideal targets in the search for indirect dark matter (DM) signals. In this work, we analyze MUSE spectroscopic observations of a sample of five…
The MUSE-Faint survey. III. No large dark-matter cores and no significant tidal stripping in ultra-faint dwarf galaxies
Sebastiaan L. Zoutendijk, Mariana P. Júlio, Jarle Brinchmann +8
[Abridged] Aims. The lowest-mass galaxies, ultra-faint dwarf galaxies, promise unparalleled constraints on how feedback regulates galaxy formation, and on the small-scale matter po…
Searching for Light in the Darkness: Bounds on ALP Dark Matter with the optical MUSE-Faint survey
Marco Regis, Marco Taoso, Daniel Vaz +4
We use MUSE spectroscopic observations of the dwarf spheroidal galaxy Leo T between 470 and 935 nm to search for radiative decays of axion like particles (ALPs). Under the assumpti…
