Harassment Origin for Kinematic Substructures in Dwarf Elliptical Galaxies? [PDF]

, 2005
We have run high resolution N-body models simulating the encounter of a dwarf galaxy with a bright elliptical galaxy. The dwarf absorbs orbital angular momentum and shows counter-rotating features in the external regions of the galaxy.

The Effect of Seductive Details on Knowledge Retention in Physics Videos: A Mixed Methods Study

Journal of Research in Science Teaching, Volume 62, Issue 8, Page 1923-1940, October 2025.
ABSTRACT Research reports that interesting but irrelevant information, seductive details, in teaching material can impede learning. In science education, the inclusion of historical narratives in lessons to promote interest has been recommended but may hinder learning.

The mass of dwarf spheroidal galaxies and the missing satellite problem

, 2005
We present the results from a suite of N-body simulations of the tidal stripping of two-component dwarf galaxies comprising some stars and dark matter. We show that recent kinematic data from the local group dwarf spheroidal (dSph) galaxies suggests that

A Role for the Plastidial GPT2 Translocator in the Modulation of Lignin Biosynthesis

Plant, Cell &Environment, Volume 48, Issue 9, Page 6458-6472, September 2025.
ABSTRACT Engineering plants with reduced lignin content can result in pleiotropic growth defects. In stems of Arabidopsis plants with reduced expression of hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase (HCT), the plastidial glucose 6‐phosphate: phosphate co‐transporter GPT2 is highly overexpressed, and this coincides with reduced lignin ...

The Outer Edges of Dwarf Irregular Galaxies: Stars and Gas

, 2002
We have in recent years come to view dwarf galaxy evolution in the broader context of the cosmic evolution of large-scale structure. Dwarf galaxies, as the putative building blocks of hierarchical galaxy formation, and also as the most numerous galaxies ...

Dwarf Spheroidal Galaxies : Keystones of Galaxy Evolution [PDF]

, 1994
Dwarf spheroidal galaxies are the most insignificant extragalactic stellar systems in terms of their visibility, but potentially very significant in terms of their role in the formation and evolution of much more luminous galaxies. We discuss the present

Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

X-Ray Bright Active Galactic Nuclei in Local Dwarf Galaxies: Insights from eROSITA

The Astrophysical Journal
Although supermassive black holes (SMBHs) reside in the heart of virtually every massive galaxy, it remains debated whether dwarf galaxies commonly host SMBHs. Because low-mass galaxies may retain memory of the assembly history of their black holes (BHs),
