I am a retired engineer that has an ongoing interest in space efforts. In my youth I did work on the Apollo program but on propulsion and vehicle thermal control: not flight dynamics. I have ...
I was wondering what parameters I need to know/measure to calculate the velocity dispersion of a galaxy, specifically an AGN. Also, I have spectra where there are blueshifted and redshifted ...
Is there any astronomical phenomena that could emit strong radio waves with multiples of a discrete frequency?
In the New Scientist article Is this ET? Mystery of strange radio bursts from space, it is reported that several times since 2001, astronomers have detected fast radio bursts that seem to have a ...
Deriving Dark Matter; specifically looking for a table of stellar rotational speed versus distance from center of galaxy to derive dark matter
I'm trying to find some data that I can use to derive dark matter (in a loosey-goosey sort of way, I won't be too rigorous). I'm helping a friend out with a final project for his astronomy course and ...
I have done some research about Radio Astronomy to build a radio telescope with a number of arrays. I have read one of the prerequisites of working with radio telescope is a good knowledge about ...
