NGC 4100 Missing Spectrum

the post:

this is NGC 4100. a galaxy at ursa major, which got a lot of "young" blue stars and clouds. when i saw this pic, i immediately asked myself: whats the galaxys redshift / BLUEshift value? i didnt find any RS data to in google quickly, so would anyone else know where to find it? i still go after the myth that the chemical milieu of a galaxy might influence the redblueshift values.

my comment:

Galaxy spectrum are almost never published. That negligence was the subject of my April 8 post: Consequences of Mistaken certainty.

You are close when thinking of the " chemical milieu of a galaxy " but these shifts actually come from the intergalactic medium.

I investigated when a shift is from either calcium or hydrogen atoms in the IGM line of sight (some assumptions are possible) and posted the IGM results in my web site's research section thinking no one is interested in this trivial detail.

Because this particular  galaxy has no red shift velocity value in Wikipedia and because it a SAbc galaxy type (similar to M31 and M33 who are both blue shifted) I suspect NGC 4100 is a blue shifted calcium absorption line. Blue shifts cannot occur in an expanding universe - but they do.

My part 1 involved hydrogen in the IGM.

What about stars? Every star can have a little diferent own plasma sphere acording to different stars types and different commpositions of stars, different stars systems with different magnetic fields and electrical conditions?

My reply:

Thunderbolts describes the Electric Sun as connected to the galaxy via an axial electric current.

The Sun is part of an Alfven circuit which essentially has the Sun at the center of a sphere with the solar wind as an electric current sheet to the heliopause. The current returns to the Sun's poles. I recall Don Scott's illustration but it would take time to find it.The accompanying heliosheath separates the solar environment from the interstellar medium. The 2 Voyager probes are at that transition between these two environments.

You are correct each star has its own characteristics which we classify as star types.
