Constraining superheavy dark matter model of UHECR with SUGAR data
Hang Bae Kim, Peter Tinyakov
Models which associate the origin of the ultra-high energy cosmic rays (UHECR) with decays of relic superheavy particles predict the anisotropy of UHECR flux toward the Galactic ce…

Cosmology of Rolling Tachyon
Chanju Kim, Hang Bae Kim, Yoonbai Kim +1
We study dynamics of rolling tachyon and Abelian gauge field on unstable D-branes, of which effective action is given by Born-Infeld type nonlocal action. Possible cosmological evo…

Electromagnetic String Fluid in Rolling Tachyon
Chanju Kim, Hang Bae Kim, Yoonbai Kim +1
We study Born-Infeld type effective action for unstable D3-brane system including a tachyon and an Abelian gauge field, and find the rolling tachyon with constant electric and magn…
