Peekaboo: the extremely metal poor dwarf galaxy HIPASS J1131-31

Autor: I D Karachentsev, L N Makarova, B S Koribalski, G S Anand, R B Tully, A Y Kniazev

The dwarf irregular galaxy HIPASS J1131-31 was discovered as a source of HI emission at low redshift in such close proximity of a bright star that we call it Peekaboo. The galaxy resolves into stars in images with Hubble Space Telescope, leading to a

To date at least 10 highly flattened planes of dwarf galaxies are claimed to have been discovered in the Local Universe. The origin of these planes of galaxies remains unknown. One suggestion is that they are related to the large-scale structure of t

Observations are presented of the isolated dwarf irregular galaxy And IV made with the Hubble Space Telescope Advanced Camera for Surveys and the Giant Metrewave Radio Telescope in the 21 cm HI line. We determine the galaxy distance of 7.17 ± 0.31 M

Serendipitous discovery of a faint dwarf galaxy near a Local Volume dwarf

Autor: Aleksandra Antipova, Dmitry Makarov, Igor D. Karachentsev, L. N. Makarova, R. B. Tully

A faint dwarf irregular galaxy has been discovered in the HST/ACS field of LV J1157+5638. The galaxy is resolved into individual stars, including the brightest magnitude of the red giant branch. The dwarf is very likely a physical satellite of LV J11
