FIELDMAPS Data Release: Far-infrared Polarization in the “Bones” of the Milky Way

open access: yesThe Astrophysical Journal Supplement Series
Polarization 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

MAGAZ3NE: Far-IR and Radio Insights into the Nature and Properties of Ultramassive Galaxies at z ≳ 3

open access: yesThe Astrophysical Journal
Deep and wide-field near-infrared (NIR) surveys have recently discovered and confirmed ultramassive galaxies (UMGs; ${\mathrm{log}}({M}_{\star }/{M}_{\odot })$ > 11) spectroscopically at z ≳ 3.

Stressed detector arrays for airborne astronomy [PDF]

open access: yes
The development of stressed Ge:Ga detector arrays for far-infrared astronomy from the Kuiper Airborne Observatory (KAO) is discussed. Researchers successfully constructed and used a three channel detector array on five flights from the KAO, and have ...

Resolved Measurements of the CO-to-H2 Conversion Factor in 37 Nearby Galaxies

open access: yesThe Astrophysical Journal
We 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.

Astronomical observations with the University College London balloon borne telescope [PDF]

open access: yes
The characteristics of a telescope system which was developed for high altitude balloon astronomy are discussed. A drawing of the optical system of the telescope is provided. A sample of the signals recorded during one of the flights is included.
