The article Current and future constraints on extended Bekenstein-type models for a varying fine-structure constant has just been published at the Physical Review D. Part of the work described therein was done during and after AstroCamp 2017, and the authors include two students and one monitor from this edition. Two other authors have also participated in previous AstroCamps as students and/or monitors. The article can also be read here, and will soon be presented in an oral communication at IJUP2018.
