Forecasting the Cross Correlation of Terahertz Intensity Mapper [C ii] Line Intensity Maps with Euclid Galaxies

open access: yesThe Astrophysical Journal
We forecast that the Terahertz Intensity Mapper (TIM) cross-correlated with Euclid’s Deep Field Fornax (EDF-F), TIM × EDF-F, will detect the [C ii ]-galaxy cross-power spectrum at a median redshift of 1.1 with ≳7 σ confidence.

An Analysis of the Complex and Compact Outflow Cavity Carved by HOPS 361-A in NGC 2071 IR

open access: yesThe Astrophysical Journal
We present a combined Stratospheric Observatory for Infrared Astronomy (SOFIA) and two-epoch Hubble Space Telescope (HST) study of the region NGC 2071 IR containing the outflow from the protostar HOPS 361-A (NGC 2071 IRS 1).

SOFIA Polarization Spectrum of Three Star-forming Clouds

open access: yesThe Astrophysical Journal
The dust emission polarization spectrum—how the polarization percentage changes with wavelength—serves as a probe of dust grain properties in star-forming regions.

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

open access: yesAdvanced 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

open access: yesThe 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

Magnetic Fields in the Pillars of Creation

open access: yesThe 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.

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.

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.

MAGAZ3NE: Confirming Dust Deficiency and Quiescent Nature of Ultramassive Galaxies at 3 < z < 4 with ALMA Observations

open access: yesThe Astrophysical Journal
A major challenge in identifying massive quiescent galaxies at z  > 3 is distinguishing truly passive systems from dust-obscured star-forming galaxies, as both populations exhibit similar red ultraviolet-to-near-infrared colors.
