Some of these can be deliberately searched for, e.g. Lorentz violations evident in different arrival times of gamma vs radio, say, from a distant GRB. Others may come from serendipitous discoveries, at least some of which may be made by citizen scientists; for example, “Green Peas”, discovered by Galaxy Zoo volunteers, who also organized themselves to do the initial follow-up work. Who knew? These weird compact galaxies, or rather their ancestors, may have done most of the ‘heavy lifting’ in ending the ‘Dark Ages’ (i.e. ionizing the intergalactic medium, at z~7?)!
