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 ...

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.

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

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.

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.

Frontiers in Neuroscience, 2023 PurposeTo test the hypothesis that rod photoreceptor mitochondria function in vivo progressively declines over time.Methods2, 12, and 24 month-old dark- and light-adapted C57BL/6J (B6J) mice were examined by OCT. We measured (i) an index of mitochondrial

Les sites de hauteur en Crète pendant les siècles obscurs
Projets de Paysage, 2010 At the end of the Bronze Age in Crete, a particular phenomenon makes its appearance. In effect, with the disappearing of centralized power and big palaces, the population scatters and leaves sites in lowland or along the coast to the advantage of site in
