A Confirmed Deficit of Hot and Cold Dust Emission in the Most Luminous Little Red Dots

open access: yesThe Astrophysical Journal Letters
Luminous broad H α emission and red rest-optical spectral energy distributions (SEDs) are the hallmark of compact little red dots (LRDs), implying highly attenuated dusty starbursts and/or obscured active galactic nuclei (AGN).

Geologically Recent Formation of Some Tesserae on Venus by Plains Deformation

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Tessera is a pervasively deformed terrain type on Venus generally interpreted as the oldest preserved material on the surface. Large expanses of this terrain type are typically elevated and have been hypothesized to be felsic, perhaps analogous to Earth's continents and even to date from an era with a more Earth‐like climate earlier in Venus ...

Blast: the far-infrared/radio correlation in distant galaxies [PDF]

open access: yes, 2010
We investigate the correlation between far-infrared (FIR) and radio luminosities in distant galaxies, a lynchpin of modern astronomy. We use data from the Balloon-borne Large Aperture Submillimetre Telescope (BLAST), Spitzer, the Large Apex BOlometer ...

Martian Proton Albedo as Signature of Near‐Surface Water

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

The Laboratory Astrophysics Spectroscopy Programme at Imperial College London

open access: yesGalaxies, 2018
Accurate atomic parameters, such as transition probabilities, wavelengths, and energy levels, are indispensable for the analysis of stellar spectra and the obtainment of chemical abundances.

Spectral Characterization of CO2‐H2O Ice Layering Under Controlled Mars Polar Conditions as Laboratory Analogs for Seasonal Cap Activity

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Seasonal CO2 and H2O ice blanket the Martian polar caps, and their spectral contributions mix during seasonal evolution. Particularly in late northern winter, the spectral signature of H2O ice obscures that of CO2 ice. Using the MARVIN chamber at York University, we produced controlled analogs of layered polar ice under Mars‐like pressure (∼6 ...

A balloon-borne 1 meter telescope for far-infrared astronomy

open access: yes, 1974
The flight of a balloon-borne one-meter telescope for infrared astronomy in the wavelength interval of 40 to 240 microns is discussed. The gyro-stabilized telescope mapped the intensity of the far infrared radiation from NGC 7538, Mars, the Orion Nebula,

First results from high redshift quasar searches in VIKING [PDF]

open access: yes, 2012
This thesis presents the discovery of the first luminous z & 6.5 quasars in the VISTA kilo-degree Infrared Galaxy Survey (VIKING). After some basic quality control, quasar selection is investigated via use of initial data supplementedwith ...

Far infrared supplement: Catalog of infrared observations, second edition

open access: yes, 1988
The Far Infrared Supplement: Catalog of Infrared Observations summarizes all infrared astronomical observations at far infrared wavelengths (5 to 1000 microns) published in the scientific literature from 1965 through 1986.
