But I am looking for a citeable reference on the J-homomorphism as a map of spectra
Westerland’s slides mention this on p. 5. But is there a citeable account that goes with this?

added pointer to Gaudens-Menichi 07 for expressing the canonical -action on general -fold loop spaces in terms of the J-homomorphisms.
If anyone has more pointers for this, let me know.
]]>added a few more pointers to discussion of the image of J in terms of /-localization of the sphere spectrum:
Mark Behrens, section 1 of Introduction talk at Talbot 2013: Chromatic Homotopy Theory (pdf, pdf) {#Behrens13}
Ben Knudsen, First chromatic layer of the sphere spectrum = homotopy of the -local sphere, talk at 2013 Pre-Talbot Seminar (pdf) {#Knudsen13}
Vitaly Lorman, Chromatic homotopy theory at height 1 and the image of , talk at Talbot 2013: Chromatic Homotopy Theory (pdf) {#Lorman13}
Is there anything else?
]]>added the characterization of the image of J in terms of chromatic homotopy theory (in the -local sphere spectrum) to Image of J – In terms of chromatic homotopy theory
]]>I have added some more comments to J-homomorphism – Definition – On groups meant to be careful about the argument of how the continuous action of the topological group on the topological space turns into an -action of the homotopy type of the stable orthogonal group on the sphere spectrum.
]]>have added the list of values of for low .
