A Cool Dust Factory in the Crab Nebula: A Herschel Study of the Filaments
H. L. Gomez, O. Krause, M. J. Barlow +13
Whether supernovae are major sources of dust in galaxies is a long-standing debate. We present infrared and submillimeter photometry and spectroscopy from the Herschel Space Observ…
The Earliest Phases of Star Formation (EPoS): A Herschel Key Program - The precursors to high-mass stars and clusters
Sarah Ragan, Thomas Henning, Oliver Krause +14
(Abridged) We present an overview of the sample of high-mass star and cluster forming regions observed as part of the Earliest Phases of Star Formation (EPoS) Herschel Guaranteed T…
The heating of dust by old stellar populations in the Bulge of M31
Brent Groves, Oliver Krause, Karin Sandstrom +9
We use new Herschel multi-band imaging of the Andromeda galaxy to analyze how dust heating occurs in the central regions of galaxy spheroids that are essentially devoid of young st…
Probing Interstellar Dust with Infrared Echoes from the Cas A Supernova
Frédéric P. A. Vogt, Marc-André Besel, Oliver Krause +1
We present the analysis of an IRS 5-38 μm spectrum and MIPS photometric measurements of an infrared echo near the Cassiopeia A supernova remnant observed with the Spitzer Space Tel…
Thirty years of SN 1980K: Evidence for light echoes
Ben E. K. Sugerman, Jennifer E. Andrews, Michael J. Barlow +7
We report optical and mid-infrared photometry of SN 1980K between 2004 and 2010, which show slow monotonic fading consistent with previous spectroscopic and photometric observation…
Resolving the Far-IR Line Deficit: Photoelectric Heating and Far-IR Line Cooling in NGC 1097 and NGC 4559
Kevin V. Croxall, J. D. Smith, M. G. Wolfire +30
The physical state of interstellar gas and dust is dependent on the processes which heat and cool this medium. To probe heating and cooling of the ISM over a large range of infrare…
