Exploring the String Axiverse with Black Holes

We analyse a large ensemble of axion data derived directly from string theory compactifications arising in the Kreuzer-Skarke database.  We then use astrophysical measurements of spinning black holes to constrain our axion systems and, for the first time, exclude portions of the string axiverse.
