The Herschel Virgo Cluster Survey. XVII. SPIRE point-source catalogs and number counts
Ciro Pappalardo, George J. Bendo, Simone Bianchi +19
We present three independent catalogs of point-sources extracted from SPIRE images at 250, 350, and 500 micron as a part of the Herschel Virgo Cluster Survey (HeViCS). The source p…
High-resolution, 3D radiative transfer modeling : I. The grand-design spiral galaxy M51
Ilse De Looze, Jacopo Fritz, Maarten Baes +20
Context: Dust reprocesses about half of the stellar radiation in galaxies. The thermal re-emission by dust of absorbed energy is considered driven merely by young stars and, conseq…
An extremely low gas-to-dust ratio in the dust-lane lenticular galaxy NGC 5485
Maarten Baes, Flor Allaert, Marc Sarzi +7
Evidence is mounting that a significant fraction of the early-type galaxy population contains substantial reservoirs of cold interstellar gas and dust. We investigate the gas and d…
The physical characteristics of the gas in the disk of Centaurus A using the Herschel Space Observatory
T. J. Parkin, C. D. Wilson, M. R. P. Schirm +12
We search for variations in the disk of Centaurus A of the emission from atomic fine structure lines using Herschel PACS and SPIRE spectroscopy. In particular we observe the [C II]…
A resolved analysis of cold dust and gas in the nearby edge-on spiral NGC 891
T. M. Hughes, M. Baes, J. Fritz +18
We investigate the connection between dust and gas in the nearby edge-on spiral galaxy NGC 891. High resolution Herschel PACS and SPIRE 70, 100, 160, 250, 350, and 500 m images…
Dust Spectral Energy Distributions of Nearby Galaxies: an Insight from the Herschel Reference Survey
L. Ciesla, M. Boquien, A. Boselli +20
We gather infrared (IR) photometric data from 8 to 500 microns (Spitzer, WISE, IRAS and Herschel) for all of the HRS galaxies. Draine & Li (2007) models are fit to the data from wh…
The applicability of FIR fine-structure lines as Star Formation Rate tracers over wide ranges of metallicities and galaxy types
Ilse De Looze, Diane Cormier, Vianney Lebouteiller +19
We analyze the applicability of far-infrared fine-structure lines [CII] 158 micron, [OI] 63 micron and [OIII] 88 micron to reliably trace the star formation rate (SFR) in a sample…
