A New Method to Simulate Dark Matter–Baryon Interactions and Application to an Isolated Disk Galaxy

The Astrophysical Journal
We report on a new method for incorporating interactions between dark matter (DM) and baryons in cosmological simulations, capable of handling the challenging regime in which the DM particle mass is comparable to or lighter than the baryon mass.

Humble beginnings of the Australian giant wood moth (Endoxyla cinereus): A century‐old mystery solved

Insect Science, EarlyView.
The Australian giant wood moth (Endoxyla cinereus) feeds within the galls of scale insects (Apiomorpha) before transitioning into its wood‐boring eucalypt larval phase. This transitionary phase may be key to its multi‐year development, at the end of which it can produce over 100 000 eggs.

A Physically Motivated Framework to Compare the Merger Timescales of Isolated Low- and High-mass Galaxy Pairs Across Cosmic Time

The Astrophysical Journal
The merger timescales of isolated low-mass pairs (10 ^8 < M _* < 5 × 10 ^9 M _⊙ ) on cosmologically motivated orbits have not yet been studied in detail, though isolated high-mass pairs (5 × 10 ^9 < M _* < 10 ^11 M _⊙ ) have been studied extensively.

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]

, 2006
In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

Effect of Salinity Stress on Gut–Brain–Gonad Axis in the Red‐Eared Slider (Trachemys scripta elegans)

Integrative Zoology, EarlyView.
The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.

Ring or No Ring—Revisiting the Multiphase Nuclear Environment in M31

The Astrophysical Journal
Nuclear rings, prevalent in barred galaxies, are essential to understanding gas transport toward galactic nuclei. However, the peculiar nuclear ring in our neighboring galaxy M31 remains poorly understood.

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

Integrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Fine-grained Morphological Study of Galaxy Pairs: A Human-in-the-loop Self-supervised Classification Framework

The Astronomical Journal
Galaxy pairs, as key probes for studying galaxy formation and evolution, provide a unique window for observing galaxy interactions, including the associated exchange of material and related galaxy formation activities.

Longitudinal and cross‐sectional perspectives on elementary school children's post‐error slowing in reading and arithmetic

British Journal of Educational Psychology, EarlyView.
Abstract Background This study investigated the development of primary school children's error‐related adjustments in reading and arithmetic, both cross‐sectionally and longitudinally. Aims We aimed to uncover monitoring‐based cognitive control processes and often‐overlooked strategy use in academic tasks requiring a balancing of speed and accuracy ...
