A distance of 13 Mpc resolves the claimed anomalies of the galaxy lacking dark matter
Ignacio Trujillo, Michael A. Beasley, Alejandro Borlaff +10
The claimed detection of a diffuse galaxy lacking dark matter represents a possible challenge to our understanding of the properties of these galaxies and galaxy formation in gener…
Integrated-light analyses vs. colour-magnitude diagrams - II. Leo A, an extremely young dwarf in the Local Group
T. Ruiz-Lara, C. Gallart, M. Beasley +7
Context. Most of our knowledge on the stellar component of galaxies is based on the analysis of distant systems and comes from integrated light data. It is important to test whethe…
Spectroscopic characterisation of the stellar content of ultra diffuse galaxies
T. Ruiz-Lara, M. A. Beasley, J. Falcón-Barroso +7
Understanding the peculiar properties of Ultra Diffuse Galaxies (UDGs) via spectroscopic analysis is a challenging task requiring very deep observations and exquisite data reductio…
Black-hole-regulated star formation in massive galaxies
Ignacio Martin-Navarro, Jean P. Brodie, Aaron J. Romanowsky +2
Super-massive black holes, with masses larger than a million times that of the Sun, appear to inhabit the centers of all massive galaxies. Cosmologically-motivated theories of gala…
