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,

Maximizing Science Capability for Far-Infrared Space Missions

open access: yes, 2004
The far-infrared and submillimeter region (20 microns-800 microns) has perhaps the greatest potential of all wavelengths for advancement in astronomy. When viewed in terms of the cosmic backgrounds, the far-IR is extremely important: half of the total ...

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.

Electromagnetic Techniques for Analysis and Design of Ultra Sensitive Receivers for Far-Infrared Astronomy [PDF]

open access: yes, 2015
This thesis focuses on EM (electromagnetic) modelling methods for simulating the behaviour of receivers and detectors for far-IR (far-infrared) astronomy and CMB (cosmic microwave background) applications, toward an optimum design for SAFARI (the ...

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.
