Structure and Evolution of the Opacity of Spiral Disks
B. W. Holwerda, R. A. Gonzalez, W. C. Keel +3
The opacity of a spiral disk due to dust absorption influences every measurement we make of it in the UV and optical. Two separate techniques directly measure the total absorption…
Structure and Evolution of the Opacity of Spiral Disks

The volume densities of GMCs in M81
Jonathan S. Heiner, Ronald J. Allen, Bjorn H. C. Emonts +1
HI features near young star clusters in M81 are identified as the photodissociated surfaces of Giant Molecular Clouds (GMCs) from which the young stars have recently formed. The HI…
The Opacity of Spiral Galaxy Disks: dust opacity from calibrated counts of distant galaxies
B. W. Holwerda, R. A. Gonzalez, Ronald J. Allen +1
The opacity of foreground spiral disks can be probed from the number of distant galaxies seen through them. To calibrate this number for effects other than the dust extinction, Gon…
Total Opacity of Local Group Galaxies and Large Scale Structure behind the Galactic Bulge
Rosa A. Gonzalez, Benne Holwerda, Laurent Loinard +2
Recently, we have developed and calibrated the Synthetic Field Method to derive total extinction through disk galaxies. The method is based on the number counts and colors of dista…
Cold Molecular Gas as a Possible Component of Dark Matter in the Outer Parts of Disk Galaxies
Ronald J. Allen, Rosa Diaz-Miller
In the last few years new evidence has been presented for the presence of ongoing massive star formation in the outer HI disks of galaxies. These discoveries strongly suggest that…
