Not only is this different from other galactic bubbles, but it makes the researchers' work that much more challenging, said Malyshev's co-lead, KIPAC postdoctoral researcher Anna Franckowiak.
"Since the Fermi bubbles have no known counterparts in other wavelengths in areas high above the galactic plane, all we have to go on for clues are the gamma rays themselves," she said. "It's very tricky to model," said Franckowiak. "Subtracting all those contributions didn't subtract the bubbles," Franckowiak said. "The bubbles do exist and their properties are robust. In other words, the bubbles don't disappear when other gamma-ray sources are pulled out of the Fermi data - in fact, they stand out quite clearly. Franckowiak says more data is necessary before they can narrow down the origin of the bubbles any further. "What would be very interesting would be to get a better view of them closer to the galactic center," she said, "but the galactic gamma ray emissions are so bright we'd need to get a lot better at being able to subtract them.
