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.

The Plant Genome, Volume 18, Issue 1, March 2025.Abstract Goatgrasses with U‐ and M‐genomes are important sources of new alleles for wheat breeding to maintain yield and quality under extreme conditions. However, the introgression of beneficial traits from wild Aegilops species into wheat has been limited by poor knowledge of their genomes and scarcity of molecular tools.

Wandering globular clusters: the first dwarf galaxies in the universe?
, 2010 In the last decade we witness an advent of new types of dwarf stellar systems in cluding ultra-compact dwarfs, ultra-faint dwarf spheroidals, and exotic globular clusters, breaking the old simple paradigm for dwarf galaxies and globular clusters.

The Magellanic Group and the Seven Dwarfs [PDF]
, 2008 The Magellanic Clouds were the largest members of a group of dwarf galaxies that entered the Milky Way (MW) halo at late times. This group, dominated by the LMC, contained ~4% of the mass of the Milky Way prior to its accretion and tidal disruption, but ~

Quantitative Assessment of GOES 8–15 > ${ >} $0.6 and > ${ >} $4 MeV Radiation Belt Electron Fluxes
Space Weather, Volume 23, Issue 3, March 2025.Abstract On Geostationary Operational Environmental Satellites (GOES) 8–15 (1996–2020), the Energetic Particle Sensor (EPS) included three integral electron channels, with nominal lower energies of 0.6 MeV (E1), 2 MeV (E2) and 4 MeV (E3). The > ${ >} $2 MeV channel has received more attention than the other two channels, because it is used by the NOAA ...

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 Rotating Satellite Plane around Milky Way–like Galaxy from the TNG50 Simulation
The Astrophysical Journal, 2023 We study the satellite plane problem of the Milky Way (MW) by using the recently published simulation data of TNG50-1. Here, we only consider the satellite plane consisting of the brightest 14 MW satellites (11 classical satellites plus Canes Venatici I,
