We study the effect of noise on the evolution of the growth factor of density perturbations in the context of the ΛCDM model. Stochasticity is introduced as a Wiener process amplified by an intensity parameter α. By comparing the evolution of deterministic and stochastic cases for different values of α we estimate the intensity level necessary to make noise relevant for cosmological tests based...

For about 100 years the amplitude of the 4 d pulsation in Polaris has decreased. We present new results showing a significant increase in the amplitude based on 4.5 years of continuous monitoring from the ground and with two satellite missions.

The analyzability of the universe into subsystems requires a concept of the “independence” of the subsystems, of which the relativistic quantum world supports many distinct notions which either coincide or are trivial in the classical setting. The multitude of such notions and the complex relations between them will only be adumbrated here. The emphasis of the discussion is placed upon the warr...
