- Telescopes hint at neutrino beacon at the heart of the Milky Way Nov. 26, 2014 Thanks to a confluence of data from a suite of vastly different telescopes, there are tantalizing clues that the massive black hole at the core of the Milky Way may be a cosmic accelerator. In a recent paper published in the journal Physical Review D, a team led by University of Wisconsin-Madison physicist Yang Bai reports a correlation of IceCube data with a recorded burst of X-rays from Sagittarius A, an object at the center of our galaxy that is believed to be a supermassive black hole.
- Nathan Whitehorn a 2014 'Young Star' in astrophysics Feb. 21, 2014 Nathan Whitehorn, a postdoctoral researcher on the IceCube project at the University of Wisconsin-Madison, has been named a “Young Star” by the Division of Astrophysics of the American Physical Society (APS).
- Fledgling supernova remnant reveals neutron star's secrets Dec. 4, 2013 With the help of NASA’s Chandra X-ray Observatory and the Australia Telescope Compact Array, an international team of astronomers has identified the glowing wreck of a star that exploded a mere 2,500 years ago — the blink of an eye in astronomical terms.
- IceCube Neutrino Observatory reports first evidence for extraterrestrial high-energy neutrinos May 15, 2013 A massive telescope in the Antarctic ice reports the detection of 28 extremely high-energy neutrinos that might have their origin in cosmic sources. Two of these reached energies greater than 1 petaelectronvolt (PeV), an energy level thousands of times higher than the highest energy neutrino yet produced in a manmade accelerator.
- International astrophysics reaches Milwaukee April 16, 2013 Trips to the South Pole usually require a lot of specialized equipment, but Nils Irland's packing list for his November 2012 visit included some items unusual even by those standards: a specially designed video camera, extra batteries, and lots and lots of data storage.
