Is there a connection between Broad Absorption Line Quasars and Narrow Line Seyfert 1 galaxies?
Dirk Grupe, John A. Nousek
We consider whether Broad Absorption Line Quasars (BAL QSOs) and Narrow Line Seyfert 1 galaxies (NLS1s) are similar, as suggested by Brandt & Gallagher (2000) and Boroson (2002). F…
Seven broad absorption line quasars with excess broad band absorption near 2250 Å
Shaohua Zhang, Jian Ge, Peng Jiang +6
We report the discovery of excess broad band absorption near 2250 A (EBBA) in the spectra of seven broad absorption line (BAL) quasars. By comparing with the statistical results fr…
Star Formation in High-Redshift Cluster Ellipticals
Cory R. Wagner, Mark Brodwin, Gregory F. Snyder +11
We measure the star formation rates (SFRs) of massive () early-type galaxies (ETGs) in a sample of 11 high-redshift () galaxy clusters…
Black holes as gases of punctures with a chemical potential: Bose-Einstein condensation and logarithmic corrections to the entropy
Olivier Asin, Jibril Ben Achour, Marc Geiller +2
We study the thermodynamical properties of black holes when described as gases of indistinguishable punctures with a chemical potential. In this picture, which arises from loop qua…
The XMM deep survey in the CDF-S VIII. X-ray properties of the two brightest sources
K. Iwasawa, C. Vignali, A. Comastri +7
We present results from the deep XMM-Newton observations of the two brightest X-ray sources in the Chandra Deep Field South (CDFS), PID 203 (z=0.544) and PID 319 (z=0.742). The lon…
Algorithmic randomness for Doob's martingale convergence theorem in continuous time
Bjørn Kjos-Hanssen, Paul Kim Long V. Nguyen, Jason Rute
We study Doob's martingale convergence theorem for computable continuous time martingales on Brownian motion, in the context of algorithmic randomness. A characterization of the cl…
A Search for Pulsations from Geminga Above 100 GeV with VERITAS
E. Aliu, S. Archambault, A. Archer +81
We present the results of 71.6 hours of observations of the Geminga pulsar (PSR J0633+1746) with the VERITAS very-high-energy gamma-ray telescope array. Data taken with VERITAS bet…
Variability-selected Active Galactic Nuclei in the VST-SUDARE/VOICE Survey of the COSMOS Field
D. De Cicco, M. Paolillo, G. Covone +16
Optical variability has proven to be an effective way of detecting AGNs in imaging surveys, lasting from weeks to years. In the present work we test its use as a tool to identify A…
SXP 5.05 = IGR J00569-7226 : using X-rays to explore the structure of a Be stars circumstellar disk
M. J. Coe, E. S. Bartlett, A. J. Bird +5
On MJD 56590-1 (2013 Oct 25-26) observations of the Magellanic Clouds by the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) observatory discovered a previously-unreport…
Repeated, Delayed Torque Variations Following X-ray Flux Enhancements in the Magnetar 1E1048.15937
R. F. Archibald, V. M. Kaspi, C. -Y. Ng +4
We report on two years of flux and spin evolution monitoring of 1E 1048.15937, a 6.5-s X-ray pulsar identified as a magnetar. Using {\it Swift} XRT data, we observed an X-ray ou…
An algebraic method for constructing stable and consistent autoregressive filters
John Harlim, Hoon Hong, Jacob L. Robbins
In this paper, we introduce an algebraic method to construct stable and consistent univariate autoregressive (AR) models of low order for filtering and predicting nonlinear turbule…
Investigating Broadband Variability of the TeV Blazar 1ES 1959+650
E. Aliu, S. Archambault, T. Arlen +92
We summarize broadband observations of the TeV-emitting blazar 1ES 1959+650, including optical R-band observations by the robotic telescopes Super-LOTIS and iTelescope, UV observat…
A uniform additive Schwarz preconditioner for the -version of Discontinuous Galerkin approximations of elliptic problems
Paola F. Antonietti, Marco Sarti, Marco Verani +1
In this paper we design and analyze a uniform preconditioner for a class of high order Discontinuous Galerkin schemes. The preconditioner is based on a space splitting involving th…
Optimal Digital Product Maintenance with a Continuous Revenue Stream
James Fan, Christopher Griffin
We use a control framework to analyze the digital vendor's profit maximization problem. The vendor captures market share by focusing costly effort on post-launch product maintenanc…
Skew flat fibrations
Michael Harrison
A fibration of by oriented copies of is called skew if no two fibers intersect nor contain parallel directions. Conditions on and for the ex…
Effect of event selection on jetlike correlation measurement in +Au collisions at GeV
STAR Collaboration, L. Adamczyk, J. K. Adkins +327
Dihadron correlations are analyzed in GeV +Au collisions classified by forward charged particle multiplicity and zero-degree neutral energy in the A…
