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:
Hα imaging of 14 CHMDs was carried out at the Wise Observatory
on eight nights, from 2009 March to 2010 April.

Note (1): measured as the mid-point between the channels where the flux density
drops to 50 per cent of each of the two peaks (or of one, if only one is
present) at each side of the spectral feature.
Note (2): velocity width of the source line profile, w(50), is measured at the
50 per cent outer level of each of the two peaks and is corrected for
instrumental broadening.
