Near-IR TRGB Distance to Nearby Dwarf Irregular Galaxy NGC 6822

Near-IR TRGB Distance to Nearby Dwarf Irregular Galaxy NGC 6822

We report the distance modulus of nearby dwarf irregular galaxy NGC 6822 estimated from the so-called Tip of Red-giant Branch (TRGB) method. To detect the apparent magnitudes of the TRGB we use the color-magnitude diagrams (CMDs) and luminosity functions (LFs) in the near-infrared JHK bands. Foregro...
