Study properties of dwarf galaxies in and around the nearby Lynx
... Voids are delineated by luminous (L > L*) massive objects and populated by dwarfs. The galaxy densities and other parameters vary significantly from one void to another. One expects that not only galaxy interactions occur in voids much less frequently, but also DM halo and galaxy formation from dens ...

We routinely measure RVs with an accuracy of about 2 km/s, therefore running only a very small risk of missing a merger precursor, which have orbital velocities of 150 km/s or higher. The large programme was finished at the end of last semester. A total of 1014 stars were observed ...

A Tale of Two Physics
... This paper offers an alternative explanation for Dark Matter, Dark Energy, and their unexpected causal linkage by creating an alternative version using a leg of Laplace's and Le Sage’s Shadow theory. A geometric proof is derived that explains the origins of Dark Energy and Dark Matter, predicting bo ...

Abstract: It is shown that the Hubble constant can be derived from the standard luminosity function of galaxies as well as from a new luminosity function as deduced from the mass-luminosity relationship for galaxies. An analytical expression for the Hubble constant can be found from the maximum numb ...
