Deep near-infrared surface photometry and properties of Local Volume dwarf irregular galaxies

Young, Tye; Jerjen, Helmut; Lopez-Sanchez, A R; Koribalski, Baerbel S


We present deep H-band surface photometry and analysis of 40 Local Volume galaxies, a sample primarily composed of dwarf irregulars in the Cen A group, obtained using the Infrared Imager and Spectrograph 2 detector at the 3.9-m Anglo-Australian Telescope. We probe to a surface brightness of ~ 25 mag arcsec-2, reaching a 40 times lower stellar density than the Two Micron All Sky Survey (2MASS). Employing extremely careful and rigorous cleaning techniques to remove contaminating sources, we...[Show more]
