Star Formation History of Dwarf Galaxies in Cosmological Hydrodynamic Simulations
Advances in Astronomy, 2010 We examine the past and current work on the star formation (SF) histories of dwarf galaxies in cosmological hydrodynamic simulations. The results obtained from different numerical methods are still somewhat mixed, but the differences are understandable ...

Astronomische Nachrichten, Volume 347, Issue 1, January 2026.ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

An optical and infrared analysis of blue compact dwarf galaxies [PDF]
, 2010 An understanding of Blue Compact Dwarf galaxies (BCDs) and the processes occurring within their chemically un-evolved environments is fundamental in our understanding of the early universe.

A recent merger in the Fornax dwarf spheroidal galaxy [PDF]
, 2016 This contribution describes a recent photometric survey of the Fornax dwarf spheroidal galaxy. CCD photometry in two colours (V and I) was obtained for a 10 degree2 region centred on Fornax.

Evolution of Terrestrial Planetary Bodies and Implications for Habitability
Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Feedback in dwarf galaxies [PDF]
, 2012 Stellar feedback processes have been suggested as a mechanism for explaining various properties of galaxies, especially dwarf galaxies, which have weaker potentials and thus lower escape velocities for galactic winds.

Visionaries and Crackpots, Maniacs and Saints: Existential Risk and the Politics of Longtermism
Ratio, Volume 38, Issue 4, Page 268-278, December 2025.ABSTRACT Despite advancing strong claims about our collective priorities, longtermism has received little attention in debates in political philosophy. I first provide an account of longtermism that highlights the way it departs from established work on intergenerational justice.

New Arabic Records From Cairo on Supernovae 1181 and 1006
Astronomische Nachrichten, Volume 346, Issue 9, November 2025.ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...
