Red, gas-rich low surface brightness galaxies and enigmatic deviations from the Tully-Fisher relation.

O'NEIL K., BOTHUN G.D. and SCHOMBERT J.

Abstract (from CDS):

Using the refurbished 305 m Arecibo Gregorian Telescope, we detected 43 low surface brightness (LSB) galaxies from the 1997 catalog of O'Neil, Bothun, & Cornell. The detected galaxies range from 22.0 mag.arcsec^–2≤µ_B_(0)≤25.0 mag.arcsec^–2, with colors ranging from the blue through the first detection of very red LSB galaxies (B-V=-0.7 to 1.7). The M_HI/L_B of these galaxies ranges from 0.1-50 M_☉/L_☉, showing this sample to range from very gas poor to possibly the most gas-rich galaxies ever detected. One of the more intriguing results of this survey is that the galaxies with the highest M_HI/L_B_ correspond to some of the reddest (optically) galaxies in the survey, raising the question of why star formation has not continued in these galaxies. Since the average H I column density in these systems is above the threshold for massive star formation, the lack of such may indicate that these galaxies form some kind of ``optical core'' which traces a much more extended distribution of neutral hydrogen. Alternatively, a model in which no stars more massive than two solar masses form in these systems can explain the presence of both blue and red gas-rich LSB galaxies. Moreover, under this model the baryonic mass fraction (f_b) of LSB galaxies is the same as for galaxies of higher surface brightness, thus perhaps escaping the dilemma proposed by McGaugh & de Blok in 1997 with respect to LSB and high surface brightness galaxies defining the same Tully-Fisher relation.

A subset of the detected LSB galaxies have rotational velocities ≥200 km.s^–1 and yet are at least an order of magnitude below L_* in total luminosity. As such, they represent extreme departures from the standard Tully-Fisher relation. In fact, our sample does not appear to have any significant correlation between the velocity widths and absolute magnitudes, with only 40% of the galaxies falling within the 1 σ low surface brightness galaxy Tully-Fisher relation. Overall, the discovery of very red, sub-L_* but very gas-rich LSB galaxies in the nearby Universe has increased, once again, the overall parameter space occupied by disk galaxies.
