There were two bingos last week at the Pole: (1) the game, where some improvising was required for the tiles, and (2) the exclamation, which was well warranted for IceCube’s recent multimessenger results. […]
Week 28 at the Pole
IceCube neutrinos pass a test of a fundamental symmetry in nature
A new measurement of the IceCube Collaboration has put Lorentz symmetry to the test and found—yet again—that neutrinos behave as expected. The results, published in Nature Physics, are the most stringent limits to date in the neutrino sector on the existence of a Lorentz violating field. […]
Week 27 at the Pole
Last week at the Pole, the weather was perfect for starting out the second half of winter—cold but calm conditions, with some of the prettiest auroras. […]
IceCube catalog of alert events up through IceCube-170922A
Introduction A high-energy neutrino event alert was issued by IceCube on 22 September 2017 and was found coincident in direction and time with a gamma-ray flare from the blazar TXS 0506+056. As part of the analysis of this multi-messenger signal, all previous neutrinos that issued alerts within the realtime alert system (DOI:10.1016/j.astropartphys.2017.05.002), or would have […]
IceCube data from 2008 to 2017 related to analysis of TXS 0506+056
Introduction A high-energy neutrino event detected by IceCube on 22 September 2017 was coincident in direction and time with a gamma-ray flare from the blazar TXS 0506+056. The analysis of this association was reported in Science (DOI:10.1126/science.aat1378). Prompted by this association, IceCube investigated 9.5 years of data recorded in the direction of this blazar to […]
In Science: IceCube Neutrinos Point to Long-Sought Cosmic Ray Accelerator
This album supports the announcement by the IceCube Collaboration together with other observatories around the world and in space of the identification of the first likely source of high-energy neutrinos and comic rays. The results are published in two papers in Science. Find the press release here. […]
IceCube neutrinos point to long-sought cosmic ray accelerator
Observations made by the IceCube Neutrino Observatory at the Amundsen–Scott South Pole Station and confirmed by telescopes around the globe and in Earth’s orbit have for the first time provided evidence for a known blazar as a source of high-energy neutrinos. These results are presented in two papers published this week in the journal Science. […]
Week 26 at the Pole
The 4th of July is now behind us, but this view of the South Pole station continues with the red, white, and blue theme, while the other side of the station just shows the blue sky and the white snow. These image were only possible due to a bright moon, bright enough to illuminate the tracks in the snow surface. […]
Week 25 at the Pole
The recent stretch of bad weather finally broke, showing off some nice auroras. Here, you can make out a bright spot in the sky, which is Mars, soon to reach its closest approach to Earth in many years. […]
Week 24 at the Pole
Midwinter is approaching, so the winterovers got together for a group photo that they’ll use to send out traditional greetings to other stations. Looks like a bunch of happy campers. […]
