Galaxy Disruption in a Halo of Dark Matter
, 2003 The relics of disrupted satellite galaxies around the Milky Way and Andromeda have been found, but direct evidence of a satellite galaxy in the early stages of being disrupted has remained elusive.

Dwarf Cepheids in the Carina Dwarf Spheroidal Galaxy [PDF]
, 1998 We have discovered 20 dwarf Cepheids (DC) in the Carina dSph galaxy from the analysis of individual CCD images obtained for a deep photometric study of the system.

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK
Journal of Research in Science Teaching, Volume 62, Issue 8, Page 1902-1922, October 2025.ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

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),

Gas heating from spinning and non-spinning evaporating primordial black holes
Physics Letters B, 2021 Primordial black holes (PBHs) from the early Universe constitute a viable dark matter (DM) candidate and can span many orders of magnitude in mass. Light PBHs with masses around 1015 g contribute to DM and will efficiently evaporate through Hawking ...

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

THE ACS LCID PROJECT: ON THE ORIGIN OF DWARF GALAXY TYPES—A MANIFESTATION OF THE HALO ASSEMBLY BIAS? [PDF]
, 2015 We discuss how knowledge of the whole evolutionary history of dwarf galaxies, including details on the early star formation events, can provide insight on the origin of the different dwarf galaxy types. We suggest that these types may be imprinted by the
