Low-frequency gravitational-wave science with eLISA/NGO [PDF]

open access: yes, 2012
We review the expected science performance of the New Gravitational-Wave Observatory (NGO, a.k.a. eLISA), a mission under study by the European Space Agency for launch in the early 2020s. eLISA will survey the low-frequency gravitational-wave sky (from 0.

Climate Change‐Induced Distribution Shifts of Keratin‐Feeding Beetle Omorgus (Omorgus) suberosus: Implications for Olive Ridley Sea Turtle Lepidochelys olivacea Conservation

open access: yesAnimal Conservation, Volume 28, Issue 6, Page 803-816, December 2025.
Our study projects significant climate change‐induced distribution shifts of a keratin‐feeding beetle Omorgus suberosus, with expansions into higher latitudes in Europe and North America and notable habitat losses in tropical regions by 2100. Ecological niche models predict a global habitat reduction of 9.5% under SSP2–4.5 and 20.8% under SSP5–8.5 ...

Correlations Between Central Massive Objects And Their Host Galaxies: From Bulgeless Spirals to Ellipticals [PDF]

open access: yes, 2007
Recent observations by Ferrarese et al. (2006) and Wehner et al. (2006) reveal that a majority of galaxies contain a central massive object (CMO), either a supermassive black hole (SMBH) or a compact stellar nucleus, regardless of the galaxy mass or ...

Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches

open access: yesNew Phytologist, Volume 248, Issue 1, Page 370-388, October 2025.
Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...

Constraining Sub-Parsec Binary Supermassive Black Holes in Quasars with Multi-Epoch Spectroscopy. II. The Population with Kinematically Offset Broad Balmer Emission Lines [PDF]

open access: yes, 2014
A small fraction of quasars have long been known to show bulk velocity offsets in the broad Balmer lines with respect to the systemic redshift of the host galaxy.

Gill evolution in Neotropical electric fishes: Comparative phylogenetic evidence for hypoxia‐driven adaptation

open access: yesFunctional Ecology, Volume 39, Issue 8, Page 1940-1956, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tropical freshwater fishes are often exposed to hypoxia, which limits aerobic metabolism and drives the evolution of diverse physiological, behavioural and morphological adaptations.
