Ryugu Reference Project: Recommendations from the Measurement Definition Team

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

COSMOS-Web: Comprehensive Data Reduction for Wide-area JWST NIRCam Imaging

open access: yesThe Astrophysical Journal
We present the data reduction methodology used for the COSMOS-Web survey JWST NIRCam data. Covering 0.54 deg ^2 with four broadband filters (F115W, F150W, F277W, F444W) and a total exposure time of approximately 270 hr, COSMOS-Web represents the largest ...

Extinctions at 7um and 15um from the ISOGAL survey

open access: yes, 2005
The extinction laws at 7um and 15um are derived for more than 120 sightlines in the inner Galactic plane based on the ISOGAL survey data and the near-infrared data from DENIS and 2MASS. The tracers are the ISOGAL point sources with [7]-[15]

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

open access: yesExperimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

A Cometary Fluorescence Model for the ν3 Vibrational Band of Cyanogen

open access: yesThe Astrophysical Journal
Cyanogen (C _2 N _2 ) has been suspected for a long time to be present in comets and to contribute to the creation of the CN radical. So far no observations with ground-based facilities have managed to detect this species, but the Rosetta mission, thanks

Circumstellar disks and planets. Science cases for next-generation optical/infrared long-baseline interferometers

open access: yes, 2012
We present a review of the interplay between the evolution of circumstellar disks and the formation of planets, both from the perspective of theoretical models and dedicated observations.

Loess Studies in Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Missing Summer Westerly Jet Barotropic Governor Effect Explains Climate Models—Observation Discrepancies in the Indian Monsoon Trends

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract The South Asian summer monsoon has exhibited a pronounced Northwest India‐Indo‐Gangetic Plains rainfall dipole since 1999, with northwest India experiencing a 24.6% increase, while rainfall in the Indo‐Gangetic Plain has decreased by 4.4%.

AKARI Detections of Hot Dust in Luminous Infrared Galaxies

open access: yes, 2011
We present a new sample of active galactic nuclei (AGNs) identified using the catalog of the AKARI Mid-infrared(MIR) All-Sky Survey. Our MIR search has an advantage in detecting AGNs that are obscured at optical wavelengths due to extinction.

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
