Light through the dark ages: The Arabist contribution to Western ophthalmology
Oman Journal of Ophthalmology, 2012 Europe in the Middle Ages had descended into a dark period, and none more so than in the field of medicine. The rich heritage of the pagan Greeks had largely been ignored or forgotten by medieval Europe, and instead it was the early Arabist world that ...

Constraints on the Equation of State of Dark Energy and the Hubble Constant from Stellar Ages and the Cosmic Microwave Background [PDF]
, 2003 We place tight constraints on the redshift-averaged, effective value of the equation of state of dark energy, w, using only the absolute ages of Galactic stars and the observed position of the first peak in the angular power spectrum of the CMB.

21 cm angular-power spectrum from the dark ages [PDF]
, 2007 At redshifts z >~ 30 neutral hydrogen gas absorbs CMB radiation at the 21cm spin-flip frequency. In principle this is observable and a high-precision probe of cosmology.

The Tragedy of the Unexamined Cat: Why K–12 and University Education Are Still in the Dark Ages and How Citizen Science Allows for a Renaissance [PDF]
Journal of Microbiology & Biology Education, 2016 At the end of the dark ages, anatomy was taught as though everything that could be known was known. Scholars learned about what had been discovered rather than how to make discoveries. This was true even though the body (and the rest of biology) was very

Neutralino annihilations and the gas temperature in the dark ages [PDF]
, 2008 Assuming the dark matter is made entirely from neutralinos, we re-visit the role of their annihilation on the temperature of diffuse gas in the high redshift universe. We consider neutralinos of particle mass 36 GeV and 100 GeV, respectively.

The Bispectrum of Redshifted 21 Centimeter Fluctuations from the Dark Ages [PDF]
, 2007 Brightness-temperature fluctuations in the redshifted 21-cm background from the cosmic dark ages are generated by irregularities in the gas-density distribution and can then be used to determine the statistical properties of density fluctuations in the ...

LEAVING THE DARK AGES WITH AMIGA [PDF]
The Astrophysical Journal Supplement Series, 2015 We present an Analytic Model of Intergalactic-medium and GAlaxy evolution since the dark ages. AMIGA is in the spirit of the popular semi-analytic models of galaxy formation, although it does not use halo merger trees but interpolates halo properties in grids that are progressively built.

Enlightening the dark ages with dark matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Constraints on dark matter annihilation or decay offer unique insights into the nature of dark matter. We illustrate how surveys dedicated to detect the highly redshifted 21 cm signal from the dark ages will offer a new window into properties of particle dark matter.
