Ultra High Energy Cosmic Rays from Sequestered X Bursts
Peter L. Biermann, Paul H. Frampton
Assuming that there is no GZK (Greisen-Zatsepin-Kuzmin) cut-off and that super-GZK cosmic rays correlate with AGN (Active Galactic Nuclei) at cosmological distances, it is speculat…
Wavefunction of the Universe on the Landscape
Laura Mersini-Houghton
This talk reviews the proposal for dynamically selecting the most probable wavefunction of the universe propagating on the landscape of string theory, by means of quantum cosmology…
Chemical Composition of the Planet-Harboring Star TrES-1
A. Sozzetti, D. Yong, B. W. Carney +3
We present a detailed chemical abundance analysis of the parent star of the transiting extrasolar planet TrES-1. Based on high-resolution Keck/HIRES and HET/HRS spectra, we have de…
GRB 050911: a black hole - neutron star merger or a naked GRB
K. L. Page, A. R. King, A. J. Levan +16
GRB 050911, discovered by the Swift Burst Alert Telescope, was not seen 4.6 hr later by the Swift X-ray Telescope, making it one of the very few X-ray non-detections of a Gamma-Ray…
Elemental Abundance Ratios in Stars of the Outer Galactic Disk. III. Cepheids
David Yong, Bruce W. Carney, Luisa de Almeida +1
We present metallicities, [Fe/H], and elemental abundance ratios, [X/Fe], for a sample of 24 Cepheids in the outer Galactic disk. The sample have Galactocentric distances covering…
Black hole entropy, log corrections and quantum ergosphere
Michele Arzano
Quantum-gravity corrections to the probability of emission of a particle from a black hole in the Parikh-Wilczek tunneling framework are studied. We consider the effects of zero-po…
Redshifts and Velocity Dispersions of Galaxy Clusters in the Horologium-Reticulum Supercluster
M. C. Fleenor, J. A. Rose, W. A. Christiansen +4
We present 118 new optical redshifts for galaxies in 12 clusters in the Horologium-Reticulum supercluster (HRS) of galaxies. For 76 galaxies, the data were obtained with the Dual B…
The B. and M. Shapiro conjecture in real algebraic geometry and the Bethe ansatz
E. Mukhin, V. Tarasov, A. Varchenko
We prove the B. and M. Shapiro conjecture that says that if the Wronskian of a set of polynomials has real roots only, then the complex span of this set of polynomials has a basis…
Why did the Universe Start from a Low Entropy State?
R. Holman, L. Mersini-Houghton
In previous work, we showed that the answer to the question posed in the title cannot be found within an equilibrium setting. The inclusion of {\em dynamical} backreaction effects…
Search for the Invisible Decay of Neutrons with KamLAND
The KamLAND collaboration
The Kamioka Liquid scintillator Anti-Neutrino Detector (KamLAND) is used in a search for single neutron or two neutron intra-nuclear disappearance that would produce holes in the $…
Geometric Proof of a Conjecture of Fulton
Prakash Belkale
We give a geometric proof of a conjecture of W. Fulton on the multiplicities of irreducible representations in a tensor product of irreducible representations for GL(r).
Mode Identification from Combination Frequency Amplitudes in ZZ Ceti Stars
Celeste M. Yeates, J. Christopher Clemens, S. E. Thompson +1
The lightcurves of variable DA stars are usually multi-periodic and non-sinusoidal, so that their Fourier transforms show peaks at eigenfrequencies of the pulsation modes and at su…
Rubidium and lead abundances in giant stars of the globular clusters M 13 and NGC 6752
David Yong, Wako Aoki, David L. Lambert +1
We present measurements of the neutron-capture elements Rb and Pb in five giant stars of the globular cluster NGC 6752 and Pb measurements in four giants of the globular cluster M…
Suggestion of Explicit Field Transformations underlying Misaligned Supersymmetry
Paul H. Frampton
In order that nonsupersymmetric quiver gauge theories can satisfy naturalness requirements to all orders of perturbation theory, one expects a global symmetry similar to, but diffe…
Multiparametric Quantum Algebras and the Cosmological Constant
Chethan Krishnan, Edoardo Di Napoli
With a view towards applications for de Sitter, we construct the multi-parametric -deformation of the $so(5,\IC)$ algebra using the Faddeev-Reshetikhin-Takhtadzhyan (FRT) formal…
Why the Universe Started from a Low Entropy State
R. Holman, L. Mersini-Houghton
We show that the inclusion of backreaction of massive long wavelengths imposes dynamical constraints on the allowed phase space of initial conditions for inflation, which results i…
New Measurement of BR(D+ ->Rho0 Mu+ Nu) / BR(D+ ->K*0 Mu+ Nu) Branching Ratio
The FOCUS collaboration, J. M. Link
Using data collected by the FOCUS experiment at Fermilab, we present a new measurement of the charm semileptonic branching ratio BR(D+ -> rho0 mu+ nu)/BR(D+ -> K*0 mu+ nu). From a…
Geometrical Optics via electromagnetic wave quantization
John P. Hernandez
The basic laws of geometrical optics can be deduced from energy-momentum conservation for electromagnetic waves, without other wave concepts. However, the concept of quanta is requ…
Mg isotope ratios in giant stars of the globular clusters M 13 and M 71
David Yong, Wako Aoki, David L. Lambert
We present Mg isotope ratios in 4 red giants of the globular cluster M 13 and 1 red giant of the globular cluster M 71 based on spectra obtained with HDS on the Subaru Telescope. W…
Hot Populations in M87 Globular Clusters
S. T. Sohn, R. W. O'Connell, A. Kundu +5
We have obtained HST/STIS far- and near-UV photometry of globular clusters in four fields in the gE galaxy M87. To a limit of m(FUV) = 25 we detect a total of 66 globular clusters…
Do We Have Evidence for New Physics in the Sky?
Laura Mersini-Houghton
Predicting signatures of string theory on cosmological observables is not sufficient. Often the observable effects string theory may impact upon the cosmological arena may equally…
Quiver -Modules and Homology of Local Systems over an Arrangement of Hyperplanes
S. Khoroshkin, A. Varchenko
Let be an arrangement of affine hyperplanes in a complex affine space , the ring of algebraic differential operators on . We define a category of quivers associated w…
Excitonic pairing between nodal fermions
D. V. Khveshchenko, W. F. Shively
We study excitonic pairing in nodal fermion systems characterized by a vanishing quasiparticle density of states at the pointlike Fermi surface and a concomitant lack of screening…
A New Definition for the Ca4227 Feature: Is Calcium Really Underabundant in Early-type Galaxies?
L. C. Prochaska, James A. Rose, Ricardo P. Schiavon
We have investigated the abundance of calcium in early-type galaxies by measuring the strength of the Ca I 4227 absorption line in their integrated spectra. The database used is th…
