abstract
We prove that the $2^\infty$-class groups of the imaginary quadratic fields have the distribution predicted by the Cohen-Lenstra heuristic. Given an elliptic curve E/Q with full rational 2-torsion and no rational cyclic subgroup of order four, we analogously prove that the $2^\infty$-Selmer groups of the quadratic twists of E have distribution as predicted by Delaunay's heuristic. In particular, among the twists E^d with |d| < N, the number of curves with rank at least two is $o(N)$.

The size of $2$-Selmer groups for the $\frac{\pi}{3}$-congruent number problem
For square-free n ≡ 5 or 13 mod 24 with all prime factors ≡ 1 mod 4, the average 2-Selmer size of the pi/3-congruent curve is 9, yielding positive densities of Selmer rank 0/2 and 1/3.

Unveiling Arithmetic Statistics of Congruent Number Elliptic Curves via Data Science and Machine Learning
A large empirical study of congruent number elliptic curves up to D < 3×10^6 confirms several Selmer-rank heuristics but does not support the paper's headline claim that Goldfeld's conjecture is rigorously verified.
