Extinction in NGC 628 and NGC 2403

Abstract

Long-slit spectrophotometry obtained simultaneously in the spectral ranges 3950{4900 A and 8000{ 10500 A is presented for a number of giant extragalactic H ii regions (GEHRs) in the spiral galaxies NGC 628 and NGC 2403. These ranges include lines from the Balmer and Paschen series of hydrogen separated by a wide wavelength interval. The Paschen and Balmer… (More)
