Extragalactic dust. IV, NGC 7625

N. Brosch, F. Loinger

Abstract

We present a photometric study of the early-type galaxy with dust lanes NGC 7625. We derive the apparent extinction law of the particles in the dust lanes and find R∼2.8, explained as dust grains that are marginally smaller than Galactic dust grains. We analyze the emission characteristics of N 7625 at various spectral bands and discuss star formation processes therein
