The Disruption of the Sagittarius Dwarf Galaxy [PDF]
The Astrophysical Journal, 1995 Numerical simulations of dwarf spheroidal galaxies undergoing several close encounters with the Milky Way are described. By comparing our models to observed properties of the recently discovered dwarf galaxy in Sagittarius (Sgr), we discuss implications of our results for the formation and evolution of the Milky Way system.

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.

A Luminous X-Ray Active Galactic Nucleus in the Dwarf–Dwarf Galaxy Merger RGG 66
The Astrophysical JournalWe present the discovery of a luminous X-ray active galactic nucleus (AGN) in the dwarf galaxy merger RGG 66. The black hole is predicted to have a mass of M _BH ∼ 10 ^5.4 M _⊙ and to be radiating close to its Eddington limit ( L _bol / L _Edd ∼ 0.75 ...

DWARF GALAXIES OF THE LOCAL GROUP [PDF]
Annual Review of Astronomy and Astrophysics, 1998 ▪ Abstract The Local Group dwarf galaxies offer a unique window to the detailed properties of the most common type of galaxy in the Universe. In this review, I update the census of Local Group dwarfs based on the most recent distance and radial velocity determinations.

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 ...

, 2011 Some of the extremely metal-poor Blue Compact Dwarf galaxies (XBCDs) in the nearby universe form galaxy pairs with remarkably similar properties. This fact points to an intriguing degree of synchronicity in the formation history of these binary dwarf ...

New dwarf galaxy candidates in the Centaurus group [PDF]
, 2015 Recent studies of the distribution and kinematics of the Milky Way and Andromeda satellite galaxy systems have confirmed the existence of coplanar, corotating structures of galaxies. In addition to the 'missing satellite problem', these structures pose a

Ultra-compact dwarf galaxy formation by tidal stripping of nucleated dwarf galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 Ultra Compact Dwarf Galaxies (UCDs) and dwarf galaxy nuclei have many common properties, such as internal velocity dispersions and colour-magnitude trends, suggesting tidally stripped dwarf galaxies as a possible UCD origin. However, UCDs typically have sizes more than twice as large as nuclei at the same luminosity. We use a GPU-enabled version of the

The Pristine dwarf galaxy survey – IV. Probing the outskirts of the dwarf galaxy Boötes I
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT We present a new spectroscopic study of the dwarf galaxy Boötes I (Boo I) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together with the Two Degree Field multi-object system. We observed 36 high-probability Boo I stars selected using Gaia Early Data Release 3 proper motions and photometric ...
