HAWC Observations Gamma Ray Source TeV J1930+188 (image) University of Maryland Share Print E-Mail Caption HAWC observations show that a previously known gamma ray source in the Milky Way galaxy, TeV J1930+188, which is probably due to a pulsar wind nebula, is far more complicated than originally thought. Where researchers previously identified a single gamma ray source, HAWC identified several hot spots.
