1995A&A...300..675H Neutral hydrogen observations of elliptical galaxies II. The IRAS sample W. K. Huchtmeier, L. J. Sage, and C. Henkel Max-Planck-Institut fur Radioastronomie, 69 Auf dem Hugel, D-53l21 Bonn, Germany Department of Physics, University of Nevada - Las Vegas, Las Vegas NV 89154, USA Department of Astronomy, University of Maryland, College Park MD 20742, USA Received 27 July 1994 / Accepted 17 November 1994 Abstract. HI observations are reported for a total of 53 IRAS elliptical galaxies. Nearby confusing sources may be responsible for some of the 33 detections. There are 24 isolated detected galaxies, which can be split into two groups, one having the same M_HI_/L_B_ ratio as the elliptical galaxies from the RSA (M_HI_/L_B_ = 0.030+/-0.026). A second group is more than six times richer in HI (M_HI_/L_B_ = 0.206+/-0.105). The "HI-rich" galaxies have blue colors like spiral galaxies and have a tendency towards higher average dust temperatures. The large number of elliptical galaxies in compact groups (in this sample) suggests that gravitational interactions and mergers may be an important source of interstellar matter for elliptical galaxies.
