Evidence for a black hole from high rotation velocities in a sub-parsec region of NGC4258

Article Abstract:

The presence of a solar mass of 3.6 times 10 to the 7th power, identified as a black hole in the central region of the galaxy NGC4258, is revealed in the observation of rotating gas in this region. Theoretical predictions indicate the presence of large black holes at the center of galaxies. The observational evidence is provided by the presence of large masses of gases with very high density. The gases observed in NGC4258 have very high mass and density, and the spectral lines from the water masers around the center of the galaxy confirm the existence of a black hole.

Creation of visible artificial optical emissions in the aurora by high-power radio waves

Article Abstract:

Production of dramatically stronger artificial optical emissions bright enough to be visible to the naked eye in an experiment targeting the ionospheric E layer created by the natural aurora was done. Although visible levels of artificial optical emissions have not been reported previously, there were attempts made to stimulate the auroral E layer with radio waves.
