Continuous statistics of the Lyman-alpha forest at 0 < z < 1.6: the mean flux, flux distribution, and autocorrelation from HST FOS spectra
David Kirkman, David Tytler, Dan Lubin +1
We measure the amount of absorption in the Lyman-alpha forest at 0 < z < 1.6 in HST FOS spectra of 74 QSOs. At 0 < z < 1.6 we find that 79% of the absorption is from the low densit…
Reverberation Mapping of High-Luminosity Quasars: First Results
Shai Kaspi, W. N. Brandt, Dan Maoz +3
Reverberation mapping of nearby active galactic nuclei has led to estimates of broad-line-region (BLR) sizes and central-object masses for some 37 objects to date. However, success…
Invariant measures and the set of exceptions to Littlewood's conjecture
Manfred Einsiedler, Anatole Katok, Elon Lindenstrauss
We classify the measures on SL (k,R)/SL (k,Z) which are invariant and ergodic under the action of the group A of positive diagonal matrices with positive entropy. We apply this to…
Object detection in multi-epoch data
G. Jogesh Babu, Ashish Mahabal, S. G. Djorgovski +1
In astronomy multiple images are frequently obtained at the same position of the sky for follow-up co-addition as it helps one go deeper and look for fainter objects. With large sc…
The young stellar population in M17 revealed by Chandra
Patrick S. Broos, Eric D. Feigelson, Leisa K. Townsley +5
We report here results from a Chandra ACIS observation of the stellar populations in and around the Messier 17 H II region. The field reveals 886 sources, 771 of which have stellar…
Mechanics of higher-dimensional black holes in asymptotically anti-de Sitter space-times
Abhay Ashtekar, Tomasz Pawlowski, Chris Van Den Broeck
We construct a covariant phase space for Einstein gravity in dimensions d>=4 with negative cosmological constant, describing black holes in local equilibrium. Thus, space-times und…
Early Ultraviolet, Optical and X-Ray Observations of the Type IIP SN 2005cs in M51 with Swift
Peter J. Brown, Luc Dessart, Stephen T. Holland +14
We report early photospheric-phase observations of the Type IIP Supernova (SN) 2005cs obtained by Swift's Ultraviolet-Optical and X-Ray Telescopes. Observations started within two…
Achievable Rates for the General Gaussian Multiple Access Wire-Tap Channel with Collective Secrecy
Ender Tekin, Aylin Yener
We consider the General Gaussian Multiple Access Wire-Tap Channel (GGMAC-WT). In this scenario, multiple users communicate with an intended receiver in the presence of an intellige…
The Spectral Energy Distributions of AGN with Double-Peaked Balmer Lines
I. Strateva, W. N. Brandt, M. Eracleous +2
We summarize the optical, UV, and X-ray properties of double-peaked emitters -- AGN with double-peaked Balmer emission lines believed to originate in the AGN accretion disk. We foc…
A General Study of Ground States of N=2 Supergravity Theories with Symmetric Scalar Manifolds in 5 Dimensions
O. Ogetbil
After reviewing the existing results we give an extensive analysis of the critical points of the potentials of the gauged N=2 Yang-Mills/Einstein Supergravity theories coupled to t…
The 2dF-SDSS LRG and QSO Survey: QSO clustering and the L-z degeneracy
J. da Angela, T. Shanks, S. M. Croom +12
We combine the QSO samples from the 2dF QSO Redshift Survey (2QZ) and the 2dF-SDSS LRG and QSO Survey (2SLAQ) in order to investigate the clustering of z~1.4 QSOs and measure the c…
Tuning alloy disorder in diluted magnetic semiconductors in high fields to 89 T
S. A. Crooker, N. Samarth
Alloy disorder in II-VI diluted magnetic semiconductors (DMS) is typically reduced when the local magnetic spins align in an applied magnetic field. An important and untested expec…
Final Size Planar Edgeless Silicon Detectors for the TOTEM Experiment
E. Noschis
The TOTEM experiment will detect leading protons scattered in angles of microradians from the interaction point at the Large Hadron Collider. This will be achieved using detectors…
Making a Short Gamma-Ray Burst from a Long one: Implications for the Nature of GRB 060614
Bing Zhang, Bin-Bin Zhang, En-Wei Liang +3
The absence of a supernova accompanying the nearby long GRB 060614 poses a great puzzle about the progenitor of this event and challenges the current GRB classification scheme. Thi…
Clustering Analyses of 300,000 Photometrically Classified Quasars--II. The Excess on Very Small Scales
Adam D. Myers, Robert J. Brunner, Gordon T. Richards +3
We study quasar clustering on small scales, modeling clustering amplitudes using halo-driven dark matter descriptions. From 91 pairs on scales <35 kpc/h, we detect only a slight ex…
Clustering Analyses of 300,000 Photometrically Classified Quasars--I. Luminosity and Redshift Evolution in Quasar Bias
Adam D. Myers, Robert J. Brunner, Robert C. Nichol +3
Using ~300,000 photometrically classified quasars, by far the largest quasar sample ever used for such analyses, we study the redshift and luminosity evolution of quasar clustering…
Lithography-Free Fabrication of Graphene Devices
N. Staley, H. Wang, C. Puls +5
We have developed a lithography-free, all-dry process for fabricating graphene devices using an ultrathin quartz filament as a shadow mask to avoid possible contamination of graphe…
Gamma Ray Bursts Flares detected and observed by the Swift Satellite
Guido Chincarini, Alberto Moretti, Patrizia Romano +11
The detection of flares with the Swift satellite triggered a lot of bservational and theoretical interest in these phenomena. As a consequence a large analysis effort started withi…
Interferometric Observations of RS Ophiuchi and the Origin of the Near-IR Emission
B. F. Lane, J. L. Sokoloski, R. K. Barry +7
We report observations of the recurrent nova RS Oph using long-baseline near-IR interferometry. We are able to resolve emission from the nova for several weeks after the February 2…
Morse-Bott homology
Augustin Banyaga, David E. Hurtubise
We give a new proof of the Morse Homology Theorem by constructing a chain complex associated to a Morse-Bott-Smale function that reduces to the Morse-Smale-Witten chain complex whe…
Matrix model superpotentials and ADE singularities
