Want this question answered?
Yes
That's basically the definition of an active galaxy, so I would say, all of them.
A radio galaxy is anactive galaxy that is very luminous at radio wavelengths (between 10 MHz and 100 GHz). The radio emission is due to the "synchrotron process" which is caused by the acceleration of charged particles, near the speed of light) through magnetic fields.

Well, I was asking this question too, but I soon figured out what the galaxy part was used for. It is used for (when you have wi-fi) stating some of the HootOwl comments on the galaxy, and for a few akward, but adorable facts about the glorious Adam Young. :) ~Tiffany
by plotting the distribution of open clusters
It is fairly typical

Harlow Shapley studied globular clusters and used the position of the clusters to locate the sun in the middle of our galaxy. He found out he was wrong but figured out that the sun was in one of the spiral arms in our galaxy
Harlow Shapley was born on November 2, 1885 and died on October 20, 1972. Harlow Shapley would have been 86 years old at the time of death or 129 years old today.
As best we can determine, every galaxy has one in its center.
mabye yes
Probably the same as the center of YOUR galaxy.
The center of a spiral galaxy is which color
The center of a spiral galaxy is which color
The average stellar mass x the number of stars ______________________________ We can calculate the mass of the Milky Way by observing the speed at which stars orbit the center, as long as we can determine how far away they are from the center.
