Abstract
Recently, the authors with Lea Beneish established a recipe for constructing Ramanujan-Sato series for , and used this to construct 11 explicit examples of Ramanujan-Sato series arising from modular forms for arithmetic triangle groups of non-compact type. Here, we use work of Chisholm, Deines, Long, Nebe and the third author to prove a general -adic supercongruence theorem through an explicit connection to CM hypergeometric elliptic curves that provides -adic analogues of these Ramanujan-Sato series. We further use this theorem to construct explicit examples related to each of our explicit Ramanujan-Sato series examples.
