Extragalactic Results from the Infrared Space Observatory

, 2000
More than a decade ago the IRAS satellite opened the realm of external galaxies for studies in the 10 to 100 micron band and discovered emission from tens of thousands of normal and active galaxies.

Proton‐linked effects on the axial coordination in ferric and ferrous horse heart cytochrome c

Protein Science, Volume 34, Issue 11, November 2025.
Abstract The effect of pH (between pH 7.0 and 0.0) on the spectroscopic properties of ferric and ferrous derivatives of horse heart cytochrome c (hhcytc‐Fe(III) and hhcytc‐Fe(II), respectively) in 1.0M phosphate buffer is reported. This study further deepens the investigation of spectroscopic properties of a heme‐protein to very low pH (i.e., pH ≈ 0 ...

Modeling the evolution of infrared galaxies: clustering of galaxies in the cosmic infrared background [PDF]

, 2011
Context. Star-forming galaxies are highly biased tracers of the underlying dark matter density field. Their clustering can be studied through the cosmic infrared background (CIB) anisotropies.

Microbial and bryospheric photosynthesis of boreal peatlands have peatland‐type‐specific responses to long‐term drying

New Phytologist, Volume 248, Issue 3, Page 1336-1350, November 2025.
Summary The impacts of drying on bryospheric photosynthesis are poorly understood. Utilising a 20‐yr‐long experiment, we quantified the effects of long‐term water level drawdown (WLD) on links between bryospheric photosynthesis, microbial community composition, decomposition, and environmental variables.

SPITZER QUASAR AND ULIRG EVOLUTION STUDY (QUEST). IV. COMPARISON OF 1 Jy ULTRALUMINOUS INFRARED GALAXIES WITH PALOMAR-GREEN QUASARS [PDF]

, 2009
We report the results from a comprehensive study of 74 ultraluminous infrared galaxies (ULIRGs) and 34 Palomar-Green (PG) quasars within z ∼ 0.3 observed with the Spitzer Infrared Spectrograph (IRS). The contribution of nuclear activity to the bolometric

Dust Properties and Star-Formation Rates in Star-Forming Dwarf Galaxies

, 2007
We have used the Spitzer Space Telescope to study the dust properties of a sample of star-forming dwarf galaxies. The differences in the mid-infrared spectral energy distributions for these galaxies which, in general, are low metallicity systems ...

OrchardQuant‐3D: combining drone and LiDAR to perform scalable 3D phenotyping for characterising key canopy and floral traits in fruit orchards

Plant Biotechnology Journal, Volume 23, Issue 11, Page 4910-4929, November 2025.
Summary Orchard fruits such as pear and apple are important for ensuring global food security and agricultural economy as they not only provide essential nutrients, but also support biodiversity and ecosystem services. Breeders, growers and plant researchers constantly study desirable tree morphological features and floral characteristics to ensure ...

The Global Schmidt law in star forming galaxies [PDF]

, 1997
Measurements of Hα, H I, and CO distributions in 61 normal spiral galaxies are combined with published far-infrared and CO observations of 36 infrared-selected starburst galaxies, in order to study the form of the global star formation law over the full ...

Building on the Archives: Connecting the CN/CO Intensity Ratio with Global Galaxy Properties in Nearby U/LIRGs

The Astrophysical Journal
We use the CN/CO intensity ratio to obtain the dense gas fraction, f _dense , for a sample of 16 ultraluminous and luminous infrared (IR) galaxies and compare f _dense with a suite of global galaxy properties.
