On the origin of the 40-120 micron emission of galaxy disks: A comparison with H-alpha fluxes [PDF]

A comparison of 40 to 120 micron Infrared Astronomy Satellite (IRAS) fluxes with published H alpha and UBV photometry shows that the far infrared emission of galaxy disks consists of at least two components: a warm one associated with OB stars in HII ...

The first results from the Herschel-HIFI mission

, 2012
This paper contains a summary of the results from the first years of observations with the HIFI instrument onboard ESA's Herschel space observatory. The paper starts by outlining the goals and possibilities of far-infrared and submillimeter astronomy ...

Superconducting Nanowire Detection of Neutral Atoms and Molecules via Their Internal and Kinetic Energy in the eV Range

Advanced Physics Research
Superconducting nanowires are widely recognized as exceptional sensors in photonics, information processing, and astronomy. Even a single infrared photon can break Cooper pairs, generate a hot spot and trigger a measurable quantum phase transition. Here,

Measuring Star Formation Rates in the Milky Way from Hi-GAL 70 μm Observations

The Astrophysical Journal
Three methods for computing the total star formation rate (SFR) of the Milky Way agree well with a reference value of 1.65 ± 0.19 M _⊙ yr ^−1 . They are then used to determine the radial dependence of the SFR and face-on map for the Milky Way. First, the

The Arp Ring: Galactic or extragalactic? [PDF]

The Arp Ring is a faint, loop-like structure around the northern end of M81 which becomes apparent only on deep optical photographs of the galaxy. The nature of the Ring and its proximity to M81 are uncertain.

The ISOPHOT-MAMBO survey of 3CR radio sources: Further evidence for the unified schemes

, 2004
We present the complete set of ISOPHOT observations of 3CR radio galaxies and quasars, which are contained in the ISO Data Archive, providing 75 mid- and far-infrared spectral energy distributions (SEDs) between 5 and 200 micron.

Magnetic Fields in the Pillars of Creation

The Astrophysical Journal
Due to dust grain alignment with magnetic fields, dust polarization observations of far-infrared emission from cold molecular clouds are often used to trace magnetic fields, allowing a probe of the effects of magnetic fields on the star formation process.

Far-infrared observations of Circinus and NGC 4945 galaxies [PDF]

Circinus and NGC 4945 are two galaxies luminous in the infrared and are characterized by compact non thermal radio nuclei, deep silicate absorption features and unusually strong water vapor maser luminosities.

Temperature distribution of dust in luminous IRAS galaxies [PDF]

Work is currently in progress to obtain temperature distributions of dust in the most infrared-luminous galaxies. The results presented are of a preliminary nature, representing a zeroth-order approximation.
