I have an amazing undergraduate research student this summer, who I won’t name so as not to embarrass her. But I wanted to share an awesome gravitational lensing that she put together for me after only a couple of days of gearing up. Pretty cool, eh? The idea is that there is a point source in the center of the image and the top frame shows what a moving source would look like without lensing, and the bottom includes the lensing. Enjoy!
