If they're non-government/military and are operating legally I think they would most likely have a 107 waiver filed, at least to allow night flying. That does mean they'd still need to be under the weight limit but I think the number of non-107 authorizations, which would allow heavier drones, is very small.
Also I'd be surprised if a University research program had the resources to field 17 drones of this size.
