Growth of Levy trees
Thomas Duquesne, Matthias Winkel
We construct random locally compact real trees called Levy trees that are the genealogical trees associated with continuous-state branching processes. More precisely, we define a g…
Earth-mass dark halos are torn into dark mini-streams by stars
HongSheng Zhao, James E. Taylor, Joseph Silk +1
The promising neutralino dark matter particles generically condense into numerous earth-mass dark halos with smaller substructures suppressed by free streaming\cite{berezinsky}. Th…
Quantum Hall fluids, Laughlin wave functions, and ideals in the Weyl algebra
K. C. Hannabuss
It is known that non-commutative fluids used to model the Fractional Quantum Hall effect give Calogero--Moser systems. The group-theoretic description of these as reductions of fre…
Kinetic theory of polarization in the Sunyaev-Zeldovich effect
Jamie Portsmouth, Edmund Bertschinger
We apply the coherency tensor formalism to the calculation of the spectral distortions imprinted in the intensity and polarization of the cosmic microwave background radiation due…
LOFAR as a Probe of the Sources of Cosmological Reionisation
Saleem Zaroubi, Joseph Silk
We propose use of the thickness of the ionisation front as a discriminant between alternative modes of reionisation in the early universe, by stars or by miniquasars. Assuming a ph…
