Very generally, what are federal crimes?

Very generally, the list you started can be continued with any type of crime that you can think of. The general difference is that you are prosecuted by the US Attorney's Office rather then a State prosecutor. The sentencing consequences can be significantly more severe, as the federal sentencing arguments are much more rigid then the typical State statutes, and Yes, you can be prosecuted for the same offense in both courts, as Dual Sovreignity (think two authorities), permits this without constituting double jeopardy. Good luck.

That's a good question. It's also kind of a tricky one to answer. As a general matter, Congress creates federal crimes, and can create as many federal crimes as their power to legislate allows. As the Supreme Court has defined it over the years, that power is quite broad.

So, generally, federal crimes are crimes that Congress thinks should be prosecuted federally. There are currently more than 4400 federal crimes, and the list grows with each session of Congress. So, providing a list is kind of a tricky thing to do.

Procedurally, someone who commits a federal crime is prosecuted by a federal prosecutor, instead of a state prosecutor, and they go to federal court instead of state court, and, if convicted and sentenced, go to federal prison instead of state prison. Each of these differences means something significant, but the significance gets a little tricky at some point.
