New results submitted today to the Astrophysical Journal are the outcome of a combined search for neutrino point sources performed by the ANTARES and IceCube collaborations. No source has been identified, but the combined search improves the sensitivity to point sources by up to a factor of two, which delivers more stringent upper limits on the flux for the candidate sources considered in this analysis.

Week 43 at the Pole
It’s that time of year for the “changing of the guard”—for IceCube’s winterovers, that is. Last week, Christian Krueger, one of IceCube’s 2015-16 winterovers, arrived alone and can be seen walking back from the plane alongside Stephan Richter, current winterover, who was on hand to greet him. […]
IceCube sets best limits for mildly relativistic magnetic monopoles
The IceCube Collaboration today presents a search for relativistic and mildly relativistic monopoles using two years of data. No monopole candidate was observed, but IceCube data allowed setting very stringent limits for the range of velocities studied. These results have been submitted today to European Physical Journal C. […]
Week 42 at the Pole
IceCube winterover Stephan Richter took this wide angle shot of the South Pole station’s galley—in a completely empty state, not likely to found this way much longer since summer personnel will be arriving soon. The galley will be a bit busier with the expanded station population. […]
On neutrino oscillations
Neutrino physicists spend a lot of time in the dark. As a figurative statement this reflects how difficult neutrinos are to understand, but it also reveals the literal sense that we work with experiments that do not see a lot of sun—and it’s not just the South Pole, it’s also in mines, tunnels, and deep underwater in seas and lakes. But just like a rare neutrino interaction, every so often a brief flash of light offers some new truth about the nature of our universe. […]
Week 41 at the Pole
The first planes of the season have arrived at the South Pole. Two planes landed last week, first a Basler (bearing gifts) and later a Twin Otter, shown in this image. […]
Week 40 at the Pole
The winterover crew gathered at the geographic South Pole for their annual group shot.
It was a relatively quiet week for the IceCube detector, but busy in general for the station. It’s that time of year, post sunrise, when preparations for summer arrivals are in full swing. […]
IceCube Collaboration meeting begins in Copenhagen, Denmark
The IceCube Collaboration’s fall 2015 meeting begins today at the Niels Bohr Institute in Copenhagen, Denmark. Assistant Professor Jason Koskinen and Niels Bohr Professor Subir Sarkar of the University of Copenhagen host the weeklong meeting. […]
Week 39 at the Pole
The last thing you want to forget to pack when you’re off to the South Pole for a year is … your lederhosen. Afterall, Oktoberfest is among the many things that winterovering folks celebrate at the station. […]
Week 38 at the Pole
With the sun now up, outdoor preparations for summer activity at the South Pole station will move into higher gear. Calm weather last week provided an opportunity to groom the skiway, shown in this image, where the Earth’s shadow is still visible in the sky as a blue band just above the horizon. […]
