The universal rotation curve of dwarf disc galaxies
(2017-01-01)
We use the concept of the spiral rotation curves universality to investigate the luminous and dark matter properties of the dwarf disc galaxies in the local volume (size ~11 Mpc). Our sample includes 36 objects with rotation ...
MASS-TO-LIGHT VERSUS COLOR RELATIONS FOR DWARF IRREGULAR GALAXIES
(IOP PUBLISHING LTD, 2016)
We have determined new relations between UBV colors and mass-to-light ratios (M/L) for dwarf irregular (dIrr) galaxies, as well as for transformed g' - r'. These M/L to color relations (MLCRs) are based on stellar mass ...
