Probing the dynamics of extreme galaxies. I. Dark matter content in ultra-diffuse galaxies
We investigate the internal structure of two galaxies from the LEWIS sample: the ultra-diffuse galaxy UDG-1 and the extended dwarf galaxy LSB-6. Both systems exhibit coherent stellar rotation in combination with a non-negligible fraction of random motion, with no signs of ongoing disturbance. This work represents the f...
