A strict lower-limit EBL: Applications on gamma-ray absorption
, 2008 A strict lower limit flux for the extragalactic background light from ultraviolet to the far-infrared photon energies is presented. The spectral energy distribution is derived using an established EBL model based on galaxy formation. The model parameters

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

Magnetic Fields in the Pillars of Creation
The Astrophysical JournalDue 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.

A balloon-borne 1 meter telescope for far-infrared astronomy [PDF]
The flight of a balloon-borne one-meter telescope for infrared astronomy in the wavelength interval of 40 to 240 microns is discussed. The gyro-stabilized telescope mapped the intensity of the far infrared radiation from NGC 7538, Mars, the Orion Nebula,

FIELDMAPS Data Release: Far-infrared Polarization in the “Bones” of the Milky Way
The Astrophysical Journal Supplement SeriesPolarization observations of the Milky Way and many other spiral galaxies have found a close correspondence between the orientation of spiral arms and magnetic field lines on scales of hundreds of parsecs. This paper presents polarization measurements at

Resolved Measurements of the CO-to-H2 Conversion Factor in 37 Nearby Galaxies
The Astrophysical JournalWe measure the CO-to-H _2 conversion factor ( α _CO ) in 37 galaxies at 2 kpc resolution, using the dust surface density inferred from far-infrared emission as a tracer of the gas surface density and assuming a constant dust-to-metal ratio.
