Fermi Detection of γ-ray emission from the M2 Soft X-ray Flare on 2010 June 12

Fermi GBM Collaboration, Fermi LAT Collaboration, B. R. Dennis +2

The GOES M2-class solar flare, SOL2010-06-12T00:57, was modest in many respects yet exhibited remarkable acceleration of energetic particles. The flare produced an ~50 s impulsive…

Bipolar Magnetic Regions on the Sun: Global Analysis of the SOHO/MDI Data Set

J. O. Stenflo, A. G. Kosovichev

The magnetic flux that is generated by dynamo inside the Sun emerges in the form of bipolar magnetic regions. We have analyzed the whole set of solar magnetograms obtained with the…

Atoms in Flight and the Remarkable Connections between Atomic and Hadronic Physics

Stanley J. Brodsky

Atomic physics and hadron physics are both based on Yang Mills gauge theory; in fact, quantum electrodynamics can be regarded as the zero-color limit of quantum chromodynamics. I r…

Invariance properties of Miller-Morita-Mumford characteristic numbers of fibre bundles

Thomas Church, Martin Crossley, Jeffrey Giansiracusa

Characteristic classes of fibre bundles in the category of closed oriented manifolds give rise to characteristic numbers by integrating the classes over the base.…

Magnetic Flux Transport by turbulent reconnection in astrophysical flows

Elisabete M. de Gouveia Dal Pino, Márcia R. M. Leão, Reinaldo Santos-Lima +3

The role of MHD turbulence in astrophysical environments is still highly debated. An important question that permeates this debate is the transport of magnetic flux. This is partic…

Magnetic Fields in Population III Star Formation

Matthew J. Turk, Jeffrey S. Oishi, Tom Abel +1

We study the buildup of magnetic fields during the formation of Population III star-forming regions, by conducting cosmological simulations from realistic initial conditions and va…
