Ju l 1 99 8 A Survey for Low - Surface - Brightness Galaxies Around M 31 . I . The Newly Discovered Dwarf Andromeda
We present images and a color–magnitude diagram for And V, a new dwarf spheroidal companion to M31 that was found using a digital filtering technique applied to 1550 deg of the second Palomar Sky Survey. And V resolves into stars easily in follow-up 4-m V and I-band images, from which we deduce a distance of 810 ± 45 kpc using the tip of the red giant branch method. Within the uncertainties, th...
متن کاملA Survey for Low Surface Brightness Dwarf
By applying a digital ltering technique to 1550 deg 2 of the POSS-II in the vicinity of M31, we found two previously unidentiied very low surface brightness dwarf galaxies which we designate And V and VI. Follow-up imaging with the KPNO 4-m telescope resolved these into stars easily. The V-and I-band images of And V indicate a distance similar to that of M31, and {1.5. All evidence stro...

متن کاملPandas’ Cubs: Discovery of Two New Dwarf Galaxies in the Surroundings of the Andromeda and Triangulum Galaxies
We present the discovery of two new dwarf galaxies, Andromeda XXI and Andromeda XXII, located in the surroundings of the Andromeda and Triangulum galaxies (M31 and M33). These discoveries stem from the first year data of the Pan-Andromeda Archaeological Survey (PAndAS), a photometric survey of the M31/M33 group conducted with the Megaprime/MegaCam wide-field camera mounted on the Canada-France-...
متن کاملDWARF AND LOW SURFACE BRIGHTNESS GALAXIES Field Populations
The terms `dwarf' and `low surface brightness' are commonly used to mean a variety of di erent things, and are sometimes used interchangeably. It is thus necessary to explicitly quantify the de nitions which are adopted. Here I shall limit the discussion to eld galaxies which are [exponential] disks characterized by a scale size h and central surface brightness 0. The word dwarf implies things ...
