A dust component 2 kpc above the plane in NGC 891
P. Kamphuis, B. W. Holwerda, R. J. Allen +2
The halo of NGC 891 has been the subject of studies for more than a decade. One of its most striking features is the large asymmetry in H emission. In this letter, we will take…
The Opacity of Spiral Galaxy Disks V: dust opacity, HI distributions and sub-mm emission
B. W. Holwerda, R. A. González, Ronald J. Allen +1
The opacity of spiral galaxy disks, from counts of distant galaxies, is compared to HI column densities. The opacity measurements are calibrated using the ``Synthetic Field Method'…
The Opacity of Spiral Galaxies from Counts of Distant Background Galaxies
B. W. Holwerda, R. A. Gonzalez, R. J. Allen +1
We have applied the "Synthetic Field Method" on a sample of ~20 nearby galaxies in order to determine the opacity of their disks. We present preliminary results on the radial depen…
