Abstract (from CDS):

We present Herschel-SPIRE observations at 250-500µm of the giant elliptical galaxy M86 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 10kpc to the south-east. We estimate that ∼106M☉ 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 M86. The gas-to-dust ratio of the cold gas component ranges from ∼20-80. We discuss the different heating mechanisms for the dust features.
