Molecular Gas in the Bulge and Ring of NGC 7331
F. P. Israel, F. Baas
Maps of the J=2-1 12CO emission from the SbII galaxy NGC 7331 show a low-contrast ring at a radius of about 3.5 kpc. There is no evidence for a pronounced central hole in the CO di…
The faint end of the Tully-Fisher relation
J. M. Stil, F. P. Israel
We have studied the relation between HI linewidth and optical luminosity in two samples of dwarf galaxies, with special attention to the accuracy of the inclination correction. The…
Submillimetre maps of the edge-on galaxy NGC 891
F. P. Israel, P. P. van der Werf, R. P. J. Tilanus
Broadband continuum images of the edge-on galaxy NGC 891 at 850 and 450 microns are presented. These images are qualitatively very similar to the 1300 micron and CO images obtained…
A low-mass HI companion of NGC 1569?
J. M. Stil, F. P. Israel
High-sensitivity maps of the large-scale structure of atomic hydrogen in the starburst dwarf galaxy NGC 1569 show evidence for an HI cloud with a mass of 7*10**6 M_sun, at a projec…
The obscured circumnuclear region of NGC 3079
F. P. Israel, P. P. van der Werf, T. G. Hawarden +1
Images in the J, H and K bands and in the the v=1-0 S(1) line of H2 of the central region of the almost edge-on galaxy NGC 3079 reveal contributions from direct and scattered starl…
