Groups of Dwarf Galaxies in the Local Universe
The Astrophysical Journal Supplement SeriesWe present a systematic search for dwarf-galaxy groups in the local Universe ( z

Highlights of Astronomy, 1977 I would like to report on some work that Ed Turner and I have done on groups of galaxies and how groups may be used to obtain useful cosmological information. Of course the classic study of groups of galaxies was done by de Vaucouleurs (1975) who made a catalogue of groups and loose associations of galaxies in the local supercluster. Partly to obtain a

Unraveling the Electronic Structure of Silicon Vacancy Centers in 4H‐SiC
Advanced Functional Materials, EarlyView.The electronic structure of the silicon vacancy in 4H‐SiC is probed via transient absorption spectroscopy, uncovering previously inaccessible excited states of the quartet and doublet spin channels, including the V2' transition. In combination with theoretical analysis, a comprehensive picture of the electronic structure is established.

Hot Gas in Groups and Their Galaxies [PDF]
Symposium - International Astronomical Union, 1998 It is clear that there is an important interplay between galaxies and the group environment. At the velocity dispersions (~ 100 km s−1) characteristic of groups, the galaxies interact strongly, leading to triggering of star formation, and galaxy merging.

The Baryonic Mass–Halo Mass Relation of Extragalactic Systems
The Astrophysical JournalWe combine data for extragalactic systems to quantify a relation between the observed baryonic mass M _b and the enclosed dynamical mass M _200 inferred from kinematics or gravitational lensing.

A Bifunctional T3SS‐Effector Simultaneously Cleaves Host MAP Kinase and Inhibits PPM1A Phosphatase
Advanced Science, EarlyView.Pathogenic bacteria exploit the metalloprotease effector NleD to subvert host defenses. Structural, biochemical, and infection analyses reveal a bifunctional mechanism by which NleD binds and inhibits the host phosphatase PPM1A while preserving its proteolytic activity against MAPKs.

The Astrophysical JournalThe stellar mass–size relation is a sensitive probe of how environment shapes galaxy structure. We analyse this relation in the local Universe for galaxies in compact groups (CGs), low-mass groups ( M _vir ≤ 10 ^13 M _⊙ ), and high-mass groups, comparing
