David Nitz and Brian Fick are each co-authors in 6 of the Top 25 Hottest Articles in Astroparticle Physics for the 2011 year. Four of those are in the top 10, including the top most downloaded article.

The number one article was “Search for first harmonic modulation in the right ascension distribution of cosmic rays detected at the Pierre Auger Observatory,” Astroparticle Physics, 34, Issue 8, March 2011, Pages 627-639. Other co-authors with or formerly with Michigan Tech are James Chye, Johana Chirinos Diaz, Roger M. Kieckhafer, Niraj Dhital, and Tolga Yapici. READ MORE

Result puts limit on how ‘lumpy’ space-time can be.
A race between two energetic photons that began more than 7 billion years ago and spanned half the cosmos has ended in a virtual dead heat. The result, if it stands up to scrutiny, would tighten the limits, suggested by some theories, on how ‘lumpy’ space-time can be. The work, to be presented on 11 January at the 219th meeting of the American Astronomical Society in Austin, Texas, by Robert Nemiroff of the Michigan Technological University in Houghton and his colleagues, relies on an analysis of a short-lived, powerful stellar explosion known as a γ-ray burst that was recorded by NASA’s Fermi Gamma-ray Space Telescope in May 2009 and dubbed GRB 090510A. The study focused on two photons, one with an energy of 25 gigaelectronvolts (GeV) and another of about 1.5 GeV, which were separated by just 0.00136 seconds. READ MORE

Michigan Tech Research Magazine 2011 has three features on physics research this year. Left is Ranjit Pati, whose research team built a molecular computer using lessons learned from the human brain. In the middle are David Nitz and Brian Fick, who are corecipients of Michigan Tech’s 2010 Research Award in the fields of experimental particle physics and ultrahigh energy cosmic rays. On the right are boron nitride nanotubes representing the precision experimental work of Yoke Khin Yap and his research team.
