Angle-resolved photoemission of various cerium and uranium f-electron systems is presented. Topics include: (i) mapping the complex 3D Fermi surface (FS) of the prototype heavy fermion system CeRu2Si2 and its f0 reference compound LaRu2Si2, (ii) comparison of quasi-2D FS sheets in the heavy fermion superconductor CeCoIn5 and antiferromagnet CeRhIn5, (iii) the FS topology of ferromagnetic superconductor UGe2, (iv) k-resolved signatures of f-d hybridization and (v) polarization-dependent f-states in CeRu2Si2 and URu2Si2.
