Description
We present Herschel-SPIRE observations at 250-500 μm of the giant
elliptical galaxy M 86 and examine the distribution of the resolved cold
dust emission and its relation with other galactic tracers. The SPIRE
images reveal three dust components: emission from the central region; a
dust lane extending north-south; and a bright emission feature 10 kpc to
the south-east. We estimate that ~106 M_&sun; of dust is
spatially coincident with atomic and ionized hydrogen, originating from
stripped material from the nearby spiral NGC 4438 due to recent tidal
interactions with M 86. The gas-to-dust ratio of the cold gas component
ranges from ~20-80. We discuss the different heating mechanisms for the
dust features.
Herschel is an ESA space observatory with science instruments provided
by European-led Principal Investigator consortia and with important
participation from NASA.
