Dark Energy, Chaotic Fields, and Fundamental Constants
To explain the currently observed accelerated expansion of the universe, a large number of different theoretical models are presently being discussed. In one...
Dark Matter and Dark Energy: Breaking the Continuum Hypothesis?
In the present paper an attempt is made to develop a fractional integral and differen- tial, deterministic and projective method based on the assumption of the...
Dark matter content of ETGs and its relation to the local density of galaxies
We study the behaviour of the dynamical and stellar mass inside the effective radius as function of local density for early-type galaxies (ETGs). We use several...
Dark Matter in the Central Regions of Early Type Galaxies
We investigate the well-known correlations between the dynamical mass-to-light ratio M/L and other global observables of elliptical (E) and lenticular (S0)...
Ultra-diffuse galaxies (UDGs) were recently recognized as an abundant class of low-surface brightness galaxies with unusually large sizes -- found both in...
