The post-infall evolution of a satellite galaxy
, 2015 As galaxy simulations increase in resolution more attention is being paid towards the evolution of dwarf galaxies and how the simulations compare to observations. Despite this increasing resolution we are however, far away from resolving the interactions

Enrichment of Strontium in Dwarf Galaxies [PDF]
The Astrophysical Journal, 2019 Light trans-iron elements such as Sr serve as the key to understanding the astrophysical sites of heavy elements. Spectroscopic studies of metal-poor stars have revealed large star-to-star scatters in the ratios of [Sr/Ba], which indicates that there are multiple sites for the production of Sr.

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

BAF60/SWP73 subunits define subclasses of SWI/SNF chromatin remodelling complexes in Arabidopsis
New Phytologist, Volume 247, Issue 2, Page 791-812, July 2025.Summary Evolutionarily conserved switch‐defective/sucrose nonfermentable (SWI/SNF) ATP‐dependent chromatin remodelling complexes (CRCs) alter nucleosome positioning and chromatin states, affecting gene expression to regulate important processes such as proper development and hormonal signalling pathways.

X-Ray Bright Active Galactic Nuclei in Local Dwarf Galaxies: Insights from eROSITA
The Astrophysical JournalAlthough 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),

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 ...

Botanical Extract–Infused Shampoo and Hair Tonic for Hair Loss in Androgenetic Alopecia: A TREND‐Compliant, Prospective Single‐Arm Preexperimental Study [PDF]
J Cosmet DermatolABSTRACT Background Androgenetic alopecia (AGA) is the most prevalent form of hair loss, often leading to treatment discontinuation due to the adverse effects and perceived ineffectiveness of conventional treatments. Botanical extracts are gaining attention for their potential benefits in managing AGA with minimal side effects.

A dwarf galaxy remnant in Canis Major: the fossil of an in-plane accretion onto the Milky Way
, 2003 We present an analysis of the asymmetries in the population of Galactic M-giant stars present in the 2MASS All Sky catalogue. Several large-scale asymmetries are detected, the most significant of which is a strong elliptical-shaped stellar over-density ...

RECONCILING DWARF GALAXIES WITH ΛCDM COSMOLOGY: SIMULATING A REALISTIC POPULATION OF SATELLITES AROUND A MILKY WAY–MASS GALAXY [PDF]
, 2016 Low-mass “dwarf” galaxies represent the most significant challenges to the cold dark matter (CDM) model of cosmological structure formation. Because these faint galaxies are (best) observed within the Local Group (LG) of the Milky Way (MW) and Andromeda (
