Future Developments in Low Temperature Detectors for CMB and Submm Astronomy [PDF]

open access: yes, 2009
We summarize the wide range of current and upcoming developments in low temperature detectors for CMB and submillimeter astronomy. We discuss work in sensor development, photon coupling and filtering architectures, and polarimetry and how these tie to ...

Payload Selection Scheme for a Fast‐Response Planetary Defense Scouting Mission: The Satis CubeSat Study

open access: yesAdvances in Astronomy, Volume 2026, Issue 1, 2026.
The continued detection of near‐Earth asteroids with postulated close encounters with Earth is a clear motivation for planetary defense–driven mission designs. Fast reconnaissance in an imminent threat scenario (i.e., less than a few years upon impact) is crucial to gain information about an asteroid potentially impacting the Earth in the near future ...

The Eccentric Cavity, Triple Rings, Two-armed Spirals, and Double Clumps of the MWC 758 Disk [PDF]

open access: yes, 2018
Spatially resolved structures in protoplanetary disks hint at unseen planets. Previous imaging observations of the transitional disk around MWC 758 revealed an inner cavity, a ring-like outer disk, emission clumps, and spiral arms, all possibly generated

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution

open access: yesAGU Advances, Volume 6, Issue 6, December 2025.
Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

Development of the Submillimeter Band [PDF]

open access: yes, 2009
This short article attempts to summarize my contribution to the field of submillimeter spectroscopy in the dense interstellar medium. It is taken mainly from my recollections and as a result some of the dates may be inaccurate.

Our Knowledge of High-Mass Star Formation at the Dawn of Herschel [PDF]

open access: yes, 2007
We review the theories and observations of high-mass star formation emphasizing the differences with those of low-mass star formation. We hereafter describe the progress expected to be achieved with Herschel, thanks notably to Key Programmes dedicated to

Mineralogically Diverse and Salt‐Rich Regolith in Jezero Crater Characterized Using X‐Ray Spectroscopy

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Planetary Instrument for X‐ray Lithochemistry (PIXL) onboard the Perseverance rover has characterized the composition of Martian regolith at a scale of hundreds of microns using micro‐focus X‐ray fluorescence spectroscopy. PIXL data reveal a diverse population of regolith grains with distinct spectral, chemical, and crystallographic ...
