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 ...

On problems with cosmography in cosmic dark ages
Physics Letters B, 2021 Quasars show considerable promise as standard candles in a high-redshift window beyond Type Ia supernovae. Recently, Risaliti, Lusso & collaborators [1–3] have succeeded in producing a high redshift Hubble diagram (z≲7) that supports “a trend whereby

International Journal of Modern Physics D, 2016 We argue that dark matter (DM)and dark energy phenomena associated with galactic rotation curves (RC’s), X-ray cluster mass profiles, and type Ia supernova data can be accounted for via small corrections to idealized general relativistic spacetime geometries due to disordered locality.

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.

Journal of Physics A: Mathematical and Theoretical, 2022 Abstract After recalling some puzzles in cosmology and briefly reviewing the Friedmann–Lemaître cosmos a simple unified model of the ‘dark sector’ is described. This model involves a scalar field and a pseudo-scalar axion field that give rise to dark energy in the form of ‘quintessence’ and to ‘fuzzy’ dark matter, respectively ...

Vision Research, 1999 Older adults have serious difficulty seeing under low illumination and at night, even in the absence of ocular disease. Optical changes in the aged eye, such as pupillary miosis and increased lens density, cannot account for the severity of this problem, and little is known about its neural basis.

Structure of the Baryon Halo Around a Supermassive Primordial Black Hole
ParticlesAccording to some theoretical models, primordial black holes with masses of more than 108 solar masses could be born in the early universe, and their possible observational manifestations have been investigated in a number of works. Dense dark matter and
