Generation of Mesoscale Magnetic Fields and the Dynamics of Cosmic Ray Acceleration
P. H. Diamond, M. A. Malkov
The problem of the cosmic ray origin is discussed in connection with their acceleration in supernova remnant shocks. The diffusive shock acceleration mechanism is reviewed and its…
Signature of Galactic Outflows as Absorption-Free Gaps in the Ly-alpha Forest
Taotao Fang, Abraham Loeb, David Tytler +2
Powerful outflows from star-forming galaxies are expected to push away the neutral intergalactic medium (IGM) around those galaxies, and produce absorption-free gaps in the Ly-alph…
Canonical Maps to Twisted Rings
D. Rogalski, J. J. Zhang
If A is a strongly noetherian graded algebra generated in degree one, then there is a canonically constructed graded ring homomorphism from A to a twisted homogeneous coordinate ri…
Toric Degenerations and Batyrev-Borisov Duality
Mark Gross
This is an extended example of the study of mirror symmetry via log schemes and the discrete Legendre transform on affine manifolds, introduced by myself and Bernd Siebert in "Mirr…
