A Study of the Merging Dwarf Galaxy VCC322

The Astrophysical Journal
Galaxy interactions and mergers can enhance or reduce star formation, but a complete understanding of the involved processes is still lacking. The effect of dwarf galaxy mergers is even less clear than their massive counterpart.

Unravelling Hidden Trophic Interactions Among Sea Urchin Juveniles and Macroinvertebrates by DNA Amplification

Molecular Ecology, EarlyView.
ABSTRACT Rocky reefs may shift between two distinct stable states: productive algal forests, characterised by high abundance and biodiversity of macrofauna, and impoverished barrens, dominated by overgrazing sea urchins. Barren states may persist despite the recovery of adult sea urchin predators, suggesting additional stabilising mechanisms.

The Relation between AGN and Host-galaxy Properties in the JWST Era. I. Seyferts at Cosmic Noon are Obscured and Disturbed

The Astrophysical Journal
The morphology of a galaxy reflects the mix of physical processes occurring within and around it, offering indirect clues to its formation and evolution.

AGN Feedback Signatures in UV Emission

Galaxies
Supermassive black holes (SMBH) are believed to influence galaxy evolution through AGN (active galactic nuclei) feedback. Galaxy mergers are key processes of galaxy formation that lead to AGN activity and star formation.

Large‐Scale Integrative Taxonomy of the Smallest Insects Reveals Astonishing Temperate Diversity (Hymenoptera: Chalcidoidea: Mymaridae)

Molecular Ecology, EarlyView.
ABSTRACT Fairyflies (Hymenoptera: Chalcidoidea: Mymaridae) are a diverse but taxonomically understudied group of parasitoid wasps that attack the eggs of other insects. Being among the very smallest of all insects, they are often ignored in biodiversity surveys despite being one of the most abundant microhymenoptera in many habitats.

Super-size Me: The Big Multi-AGN Catalog (The Big MAC) Data Release 1: The Source Catalog

The Astrophysical Journal Supplement Series
Galaxy mergers represent the most transformative and dramatic avenue for galaxy and supermassive black hole (SMBH) evolution. Multiple active galactic nuclei (multi-AGNs) are expected to ignite, grow, and evolve alongside the host galaxies, and these ...

Automation and Augmentation in Theological Perspective

Modern Theology, EarlyView.
Abstract AI enables forms of automation that threaten unemployment and deskilling, eliminating important opportunities for the development of virtue. The concomitant loss of virtue and meaningful employment makes it a theological problem from the perspective of Catholic social teaching and theological anthropology.

CEERS Key Paper. IX. Identifying Galaxy Mergers in CEERS NIRCam Images Using Random Forests and Convolutional Neural Networks

The Astrophysical Journal Letters
A crucial yet challenging task in galaxy evolution studies is the identification of distant merging galaxies, a task that suffers from a variety of issues ranging from telescope sensitivities and limitations to the inherently chaotic morphologies of ...
