The central region of spiral galaxies as seen by Herschel. M 81, M 99, and M 100
(2010-07-01)
With appropriate spatial resolution, images of spiral galaxies in thermal infrared (~10 micron and beyond) often reveal a bright central component, distinct from the stellar bulge, superimposed on a disk with prominent ...
The Herschel Space Observatory view of dust in M81
(2010-07-01)
We use Herschel Space Observatory data to place observational constraints on the peak and Rayleigh-Jeans slope of dust emission observed at 70–500 μm in the nearby spiral galaxy M81. We find that the ratios of wave bands ...
HerMES: Far infrared properties of known AGN in the HerMES fields
(2010-07-01)
Nuclear and starburst activity are known to often occur concomitantly. Herschel-SPIRE provides sampling of the far-infrared (FIR) spectral energy distributions (SEDs) of type 1 and type 2 AGN, allowing for the separation ...
The HerMES SPIRE submillimeter local luminosity function
(2010-07-01)
Local luminosity functions are fundamental benchmarks for high-redshift galaxy formation and evolution studies as well as for models describing these processes. Determining the local luminosity function in the submillimeter ...
Probing the molecular interstellar medium of M82 with Herschel-SPIRE spectroscopy
(2010-07-01)
We present the observations of the starburst galaxy M82 taken with the Herschel SPIRE Fourier-transform spectrometer. The spectrum (194–671 μm) shows a prominent CO rotational ladder from J = 4–3 to 13–12 emitted by the ...
HerMES: The submillimeter spectral energy distributions of Herschel/SPIRE-detected galaxies
(2010-07-01)
We present colours of sources detected with the Herschel/SPIRE instrument in deep extragalactic surveys of the Lockman Hole, Spitzer-FLS, and GOODS-N fields in three photometric bands at 250, 350 and 500 μm. We compare ...
The dust morphology of the elliptical Galaxy M 86 with SPIRE
(2010-07-01)
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 ...
FIR colours and SEDs of nearby galaxies observed with Herschel
(2010-07-01)
We present infrared colours (in the 25–500 μm spectral range) and UV to radio continuum spectral energy distributions of a sample of 51 nearby galaxies observed with SPIRE on Herschel. The observed sample includes all ...
Mapping the interstellar medium in galaxies with Herschel/SPIRE
(2010-07-01)
The standard method of mapping the interstellar medium in a galaxy, by observing the molecular gas in the CO 1-0 line and the atomic gas in the 21-cm line, is largely limited with current telescopes to galaxies in the ...
The Herschel ATLAS
(2010-05-01)
The Herschel ATLAS is the largest open-time key project that will be carried out on the Herschel Space Observatory. It will survey 570 deg2 of the extragalactic sky, 4 times larger than all the other Herschel extragalactic ...
