Far-infrared absorption and dispersion studies on methyl iodide solutions [PDF]

, 1986
A far-infrared dispersive liquid cell has been developed in collaboration with the National Physical Laboratory. This New Liquid Cell enables both the absorption coefficient and refractive index of a liquid to be accurately determined over the complete ...

Unveiling a Population of Strong Galaxy–Galaxy Lensed, Faint Dusty Star-forming Galaxies

The Astrophysical Journal Letters
The measurements of the number density of galaxy–galaxy strong lenses can be used to put statistical constraints on the foreground mass distributions. Dusty galaxies uncovered in submillimeter surveys are particularly useful in this regard because of the

Nocturnal Behavior of Wintering Common Cranes (Grus grus) Under Varying Environmental Conditions

Integrative Zoology, EarlyView.
For diurnal species, nighttime represents a critical ecological boundary. Understanding the ecological determinants of nocturnal activity in taxa traditionally regarded as inactive after dusk is essential for elucidating the adaptive significance of nighttime behavior. We examined how night phase, nocturnal brightness (moon illumination and cloud cover)

Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

Ibis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...

Prospects for Observing Galaxy Spectral Energy Distribution from the Radio to the Far-infrared in the Era of Next-generation Radio Telescopes

The Astrophysical Journal
The superb sensitivity and angular resolution of the next-generation radio telescopes with combined frequency coverage of approximately over 3 orders of magnitude (100 MHz–100 GHz) will sample the radio and far-infrared (FIR) spectral energy distribution

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...

Monitoring the Dust Emission from R Aqr with SOFIA: Eclipse and Periastron Passage

The Astrophysical Journal
We present infrared (IR) spectra from our monitoring of the symbiotic Mira, R Aquarii, using the Stratospheric Observatory for Infrared Astronomy. New mid-IR photometric and spectroscopic observations using the FORCAST instrument were obtained in 2022 ...

Mid- Through Far-Infrared Astronomy: The Path to Tomorrow

, 2019
The mid- through far-infrared wavelength regime accounts for the second largest component of the spectral energy distribution of the Universe -- below the primordial cosmic background and similar in magnitude to the optical background. The far-infrared peak is due to prolific star formation within galaxies during the early lifetime of the Universe ...

Distribution and rare earth element abundances of apatite in Bennu samples determined by synchrotron X‐ray fluorescence spectroscopy

Meteoritics &Planetary Science, EarlyView.
Abstract Apatite is often the most rare earth element (REE)‐enriched mineral in chondritic meteorites. REE enrichment and fractionation levels in apatite grains can give insight into the aqueous fluids in which they formed and the conditions prevailing within the host body. In this study, we applied synchrotron X‐ray fluorescence (SXRF) spectroscopy to
