The Continuing Saga of the Not-So-Constant Constant.
The cosmological constant is a constant, right? The word “constant” is right there in the name for goodness sakes. But growing evidence suggests this might not be the case after all. Today’s authors further investigate the DESI analysis pushing our understanding of dark energy.
It’ll All B-A-O-kay – How the BAO Feature Guards Cosmological Information From Nonlinear Evolution
Today’s classic paper explains why the baryon acoustic oscillation feature faithfully ferries cosmological information to the late universe.
Dragging Along Dark Matter
As the universe’s temperatures drop, there is a type of dark matter that can freeze-in. There is one consequence: it’s a bit of a drag.
