J/MNRAS/415/431 Galaxies with wide HI profiles (Brosch+, 2011) ================================================================================ Galaxies with wide H I profiles. Brosch N., Spector O., Zitrin A. =2011MNRAS.415..431B ================================================================================ ADC_Keywords: Galaxies, radio ; H I data ; Photometry, SDSS ; Photometry, infrared ; Ultraviolet ; Morphology Keywords: galaxies: evolution - galaxies: ISM - galaxies: kinematics and dynamics - galaxies: spiral - galaxies: star formation Abstract: We investigate the nature of objects in a complete sample of 28 galaxies selected from the first sky area fully covered by the Arecibo Legacy Fast ALFA (ALFALFA) survey, being well detected and having HI profiles wider than 550km/s. The selection does not use brightness, morphology or any other property derived from optical or other spectral bands. We investigate the degree of isolation, the morphology and other properties gathered or derived from open data bases and show that some objects have wide HI profiles probably because they are disturbed or are interacting, or might be confused in the ALFALFA beam. Description: H{alpha} imaging of 14 CHMDs was carried out at the Wise Observatory on eight nights, from 2009 March to 2010 April.
