The Insistence of Blackness and the Persistence of Antiblackness in Ireland
Australian Journal of Social Issues, EarlyView.ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

A Chondritic Solar Neighborhood
The Planetary Science Journal, 2023 A persistent question in exoplanet demographics is whether exoplanetary systems form from similar compositional building blocks to our own. Polluted white dwarf stars offer a unique way to address this question, as they provide measurements of the bulk ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study presents a comparative evaluation of phosphate adsorption on pristine ZIF‐8 and Fe3O4‐doped ZIF‐8 (Fe3O4/ZIF‐8), a hybrid adsorbent combining high surface area with magnetic separability. Structural integrity and composition were confirmed using SEM, XRD, FTIR, and XPS.

Massive White Dwarfs in the 100 pc Sample: Magnetism, Rotation, Pulsations, and the Merger Fraction
The Astrophysical JournalWe present a detailed model atmosphere analysis of massive white dwarfs with M > 0.9 M _⊙ and T _eff ≥ 11,000 K in the Montreal White Dwarf Database 100 pc sample and the Pan-STARRS footprint.

The Anatomical Record, EarlyView.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Anatomical Sciences Education, EarlyView.Abstract Entertainment is deeply rooted in education, from wise‐cracking teachers to health documentaries. In the context of anatomy, this already complex relationship is entwined with deeply significant ethical considerations, often related to the field's reliance on human tissue, yet it remains unexplored.

White Dwarf Merger Remnants: The DAQ Subclass
The Astrophysical JournalFour years after the discovery of a unique DAQ white dwarf with a hydrogen-dominated and carbon-rich atmosphere, we report the discovery of four new DAQ white dwarfs, including two that were not recognized properly in the literature.

Essential work, invisible workers: The role of digital curation in COVID‐19 Open Science
Journal of the Association for Information Science and Technology, Volume 76, Issue 4, Page 703-717, April 2025.Abstract In this paper, we examine the role digital curation practices and practitioners played in facilitating open science (OS) initiatives amid the COVID‐19 pandemic. In Summer 2023, we conducted a content analysis of available information regarding 50 OS initiatives that emerged—or substantially shifted their focus—between 2020 and 2022 to address ...
