Internal Dust Correction Factors for Star Formation Rates Derived for Dusty \HII Regions and Starburst Galaxies
M. A. Dopita, B. A. Groves, R. S. Sutherland +1
Star formation rates in galaxies are frequently estimated using the Balmer line fluxes. However, these can be systematically underestimated because dust competes for the absorption…
The Internal Extinction Curve of NGC 6302 and its Extraordinary Spectrum
Brent A. Groves, Michael A. Dopita, Robert E. Williams +1
In this paper we present a new method for obtaining the optical wavelength-dependent reddening function of planetary nebulae, using the nebular and stellar continuum. The data used…
Are the Narrow Line Regions in Active Galaxies Dusty and Radiation Pressure Dominated?
M. A. Dopita, B. A. Groves, R. S. Sutherland +2
The remarkable similarity between emission spectra of narrow line regions (NLR) in Seyfert Galaxies has long presented a mystery. In photoionization models, this similarity implies…
