Plane quartic twists of X(5,3)
Julio Fernandez, Josep Gonzalez, Joan-C. Lario
Given an odd representation of the absolute Galois group of Q onto PGL(2,3) and a positive integer N, there exists a twisted modular curve defined over Q whose rational points clas…

Octahedral Galois representations arising from Q-curves of degree 2
Julio Fernández-González, Joan-Carles Lario, Anna Rio
Generically, one can attach to a Q-curve C octahedral representations Gal(Qbar/Q) --> GL(2,Fbar_3) coming from the Galois action on the 3-torsion of those abelian varieties of GL_2…
