On the Ratio of Circumference to Diameter for the Largest Observable Circles: An Empirical Approach
On the Ratio of Circumference Diameter the Largest Observable Circles Empirical Approach Instrumentation and Methods for Astrophysics
2012/4/19
I present here a measurement of pi as determined for the largest observable circles. Intriguingly, the value of 16/5 asserted by the House of Representatives of the State of Indiana in 1897 is still v...
Modelling the shapes of the largest gravitationally bound objects
Cosmology and Extragalactic Astrophysics (astro-ph.CO)

We combine the physics of the ellipsoidal collapse model with the excursion set theory to study the shapes of dark matter halos. In particular, we develop an analytic approximation to the nonlinear ev...
