Alexander (Sasha) Kashlinsky (born 1957 in Riga) is an astronomer and cosmologist working at NASA Goddard-Space-Flight-Center, known for work on dark flow[1] and the cosmic infrared background. (wikipedia)
For these stars to have produced a signal this strong, they had to be very massive stars, much bigger than what we see in the Universe.
Where they lived, how big they were, how much light they emitted, whether they even existed, we weren't sure. What we've done, we think, is obtain the first information about these stars.
We think we are seeing the collective light from millions of the first objects to form in the universe. The objects disappeared eons ago, yet their light is still traveling across the universe.
