Rotational Curves of the Milky Way Galaxy and Andromeda Galaxy in Light of Vacuum Polarization around Eicheon †
Cherkas, Sergey L.; Kalashnikov, Vladimir (Peer reviewed; Journal article, 2023)Eicheon properties are discussed. It is shown that the eicheon surface allows setting a boundary condition for the vacuum polarization and obtaining a solution describing the dark matter tail in the Milky Way Galaxy. That ... -
Vacuum Polarization Instead of “Dark Matter” in a Galaxy
Cherkas, Sergey L.; Kalashnikov, Vladimir (Journal article; Peer reviewed, 2022)We considered a vacuum polarization inside a galaxy in the eikonal approximation and found that two possible types of polarization exist. The first type is described by the equation of state p=ρ/3, similar to radiation. ...
