J/A+A/506/677   HI in Local Supercluster dwarf galaxies (Huchtmeier+, 2009)

HI-observations of dwarf galaxies in the Local Supercluster. Huchtmeier W.K., Karachentsev I.D., Karachentseva V.E. <Astron. Astrophys., 506, 677-680 (2009)> =2009A&A...506..677H (SIMBAD/NED BibCode)
ADC_Keywords: Galaxies, radio ; H I data ; Morphology ; Radial velocities Keywords: galaxies: dwarf - galaxies: evolution - galaxies: ISM Abstract: We have observed 71 dwarf galaxies of low surface brightness using the 100-m radio telescope at Effelsberg in a search for new members of 27 northern galaxy groups with characteristic distances of 8 to 15Mpc. We present radial velocities, HI-fluxes, and HI line widths for 17 detected galaxies as well as upper limits for the remaining undetected objects. Description: The HI observations were completed using the 100-m radiotelescope, which has a half power beam width of 9.3' at a wavelength of 21cm. File Summary:
