Torsion and the Gravity Dual of Parity Symmetry Breaking in AdS4/CFT3 Holography
Robert G. Leigh, Nam N. Hoang, Anastasios C. Petkou
We study four dimensional gravity with a negative cosmological constant deformed by the Nieh-Yan torsional topological invariant with a spacetime-dependent coefficient. We find an…
A Line-Of-Sight Galaxy Cluster Collision: Simulated X-Ray Observations
J. A. Zuhone, P. M. Ricker, D. Q. Lamb +1
Several lines of evidence have suggested that the the galaxy cluster Cl~0024+17, an apparently relaxed system, is actually a collision of two clusters, the interaction occurring al…
PReBeaM for Planck: A Polarized Regularized Beam Deconvolution Map-Making Method
Charmaine Armitage-Caplan, Benjamin D. Wandelt
We describe a maximum likelihood regularized beam deconvolution map-making algorithm for data from high resolution, polarization sensitive instruments, such as the Planck data set.…
A Catalog of Diffuse Interstellar Bands in the Spectrum of HD 204827
L. M. Hobbs, D. G. York, T. P. Snow +8
Echelle spectra of the double-lined spectroscopic binary HD 204827 were obtained on five nights, at a resolving power R = 38,000 and with a S/N ratio = 750 near 6000 A in the final…
Distributed Subgradient Methods and Quantization Effects
Angelia Nedić, Alex Olshevsky, Asuman Ozdaglar +1
We consider a convex unconstrained optimization problem that arises in a network of agents whose goal is to cooperatively optimize the sum of the individual agent objective functio…
The X-Ray Origin of Herbig AeBe Systems: New Insights
Murad Hamidouche, Shiya Wang, Leslie W. Looney
We present a statistical study of the X-Ray emission toward 22 Herbig AeBe stars using the Chandra archive. We probe the origin of the X-Rays toward Herbig stars: are they intrinsi…
