Congratulations to all of Casper! I agree absolutely that the development via Casper in digital receivers/backends has made significant contributions to the science community.
This gravitational wave discovery, and the excellent work of the GMRT, is a perfect example. Please continue to work together to re-imagine science and astronomy and how we do it. More amazing discoveries to follow directly the result of all of you. Thank you, gordon > > Well said, Dan.
