A search for dark matter in the galactic halo

The quest for galactic halo dark matter includes high-energy neutrino searches that might be produced by the self-annihilation of dark matter particles in our galaxy. If this is the case, IceCube should observe a characteristic anisotropy in the neutrino flux due to the additional dark-matter induced neutrinos. So far, the IceCube Collaboration has not found any significant deviation from the background expectation, following new results that have been submitted today to The European Physical Journal C.

Search for neutrino emission from extended and point-like astrophysical neutrino sources with IceCube

Posted on June 26, 2014 by Silvia Bravo

The IceCube Collaboration presents several searches for extended and point-like astrophysical neutrino sources using four years of data. No evidence of neutrino emission has been found yet, but a few models have been ruled out. This research has been submitted today to The Astrophysical Journal. […]

Week 23 at the Pole

Posted on June 26, 2014 by Jean DeMerit

Life at the Pole may be different than life elsewhere, but some things are the same just about everywhere. One of those things is celebrating holidays. Who knows? Maybe holidays are even more important when you live in small, isolated communities. Last week, at the South Pole and all over Antarctica, they were celebrating midwinter, a cultural event held in many places around the world in recognition of the winter solstice, an astronomical occurrence. […]

Week 22 at the Pole

This photograph of the ICL (IceCube Lab) almost looks as if it’s set against an artificial backdrop, but it is just the eerie effect of the sky lit by a rising moon. […]

An interview with the 2013-14 IceCube winterovers

Dag Larsen and Ian Rees arrived at the South Pole in November 2013. The brand-new winterovers had already been working for IceCube for a few weeks in Madison, learning all the ins and outs of their new job. Now they were ready to take over for Blaise Kuo Tiong and Felipe Pedreros, who had been at the Pole maintaining the detector for the previous 12 months. […]

Week 21 at the Pole

Posted on June 12, 2014 by Jean DeMerit

Some very bright auroras have been unfolding in the sky above the South Pole lately. But that doesn’t mean the only way to see an aurora is by looking upward. Here’s an aurora reflected in the metallic sphere atop the marker at the ceremonial South Pole. […]

Week 20 at the Pole

It looks like IceCube winterover Ian Rees is back to taking photographs. A good thing, too, or we wouldn’t have gotten this image of a nice aurora filling up the sky over the ICL. […]

IceCube at Neutrino 2014

Posted on June 2, 2014 by Megan Madsen

The 26th International Conference on Neutrino Physics and Astrophysics, Neutrino 2014, starts today and includes presentations from several IceCube researchers. The conference runs through June 7 in Boston, Massachusetts. […]

Week 19 at the Pole

Posted on May 28, 2014 by Jean DeMerit

A bright moon hovers above a row of summer camp buildings at the South Pole. It’s not summer there now, of course, but with such a brightly lit sky, the winterovers may be having flashbacks to a time not so long ago when the sun shone down on this camp. They still have a way to go before the sun rises here again, with lots of photos to take in the meantime. […]

Week 18 at the Pole

What better time and place for an outdoor astronomy class than midwinter at the South Pole? Clear skies present a group of expectant gazers with a multitude of stars for their viewing pleasure. […]
