Relative Sea‐Level Change, Tidal Evolution and Energy Dissipation Across the Patagonian Shelf Since the Last Glacial Maximum

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Tides play a key role in regulating shelf‐sea environments, influencing sediment dynamics, habitat distribution, long‐term carbon burial, coastal hazards, and water quality, with important socio‐economic consequences. Yet the long‐term evolution of shelf sea tides in response to sea‐level change remains poorly understood. We have developed the

Tracing the Galactic Origins of Selected Four G-type Stars in the Solar Neighborhood

The Astronomical Journal
We present a multimethod investigation of four metal-poor G-type main-sequence stars to resolve their Galactic origins. By combining high-resolution spectroscopy from PolarBase, photometric/astrometric data from Gaia DR3, and spectral energy distribution

StarHorse: A Bayesian tool for determining stellar masses, ages, distances, and extinctions for field stars

, 2018
Understanding the formation and evolution of our Galaxy requires accurate distances, ages and chemistry for large populations of field stars. Here we present several updates to our spectro-photometric distance code, that can now also be used to estimate ...

Cosmic Ray Production of $^6$Li by Structure Formation Shocks in the Early Galaxy [PDF]

, 2002
We discuss the production of the element $^6$Li in the early Galaxy by cosmic rays accelerated at structure formation shocks, driven by the hierarchical merging of sub-Galactic halos during Galaxy formation.

Recovery From Anorexia Nervosa: A Concept Analysis

Journal of Advanced Nursing, Volume 82, Issue 5, Page 4840-4875, May 2026.
ABSTRACT Aim Despite decades of research, we still know surprisingly little about how best to bring about lasting recovery from anorexia nervosa (AN). Furthermore, there is a lack of consensus in the research and treatment communities about what constitutes recovery from AN, or whether “recovery” is even an appropriate term to use in this context.

Chemical Doppelgangers in GALAH DR3: The Distinguishing Power of Neutron-capture Elements among Milky Way Disk Stars

The Astrophysical Journal
The observed chemical diversity of Milky Way stars places important constraints on Galactic chemical evolution and the mixing processes that operate within the interstellar medium. Recent works have found that the chemical diversity of disk stars is low.

RAVE as a Gaia precursor: what to expect from the Gaia RVS?

, 2015
The Radial Velocity Experiment (RAVE) is a large wide-field spectroscopic stellar survey of the Milky Way. Over the period 2003-2013, 574,630 spectra for 483,330 stars have been amassed at a resolution of R=7500 in the Ca-triplet region of 8410-8795\AA ...

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, Volume 41, Issue 3, Page 400-418, April 2026.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

The APO-K2 Catalog. I. ∼7500 Red Giants with Fundamental Stellar Parameters from APOGEE DR17 Spectroscopy and K2-GAP Asteroseismology

The Astronomical Journal
We present a catalog of fundamental stellar properties for ∼7500 evolved stars, including stellar radii and masses, determined from the combination of spectroscopic observations from the Apache Point Observatory Galactic Evolution Experiment, part of the

Determining Magnetic Field Intensity and Direction From the Anisotropy of Magnetic Remanence in Sediments

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Anisotropy of magnetic remanence (AMR) holds promise for quantifying relative paleointensity values from sedimentary rocks. A proof of concept was established for applied fields that exceeded the intensity of the geomagnetic field. Under Earth‐like fields, large uncertainties necessitate the development of a new approach to improve the ...
