Distances to Galactic methanol masers
K. L. J. Rygl, A. Brunthaler, K. M. Menten +2
We present the first EVN parallax measurements of 6.7 GHz methanol masers in star forming regions of the Galaxy. The 6.7 GHz methanol maser transition is a very valuable astrometri…
CMBPol Mission Concept Study: A Mission to Map our Origins
Daniel Baumann, Asantha Cooray, Scott Dodelson +7
Quantum mechanical metric fluctuations during an early inflationary phase of the universe leave a characteristic imprint in the polarization of the cosmic microwave background (CMB…
Stochasticity and traffic jams in the transcription of ribosomal RNA: Intriguing role of termination and antitermination
Stefan Klumpp, Terence Hwa
In fast growing bacteria, ribosomal RNA (rRNA) is required to be transcribed at very high rates to sustain the high cellular demand on ribosome synthesis. This results in dense tra…
Planets in Stellar Clusters Extensive Search. V. Search for planets and identification of 18 new variable stars in the old open cluster NGC 188
B. J. Mochejska, K. Z. Stanek, D. D. Sasselov +7
We have undertaken a long-term project, Planets in Stellar Clusters Extensive Search (PISCES), to search for transiting planets in open clusters. In this paper we present the resul…
For objective causal inference, design trumps analysis
Donald B. Rubin
For obtaining causal inferences that are objective, and therefore have the best chance of revealing scientific truths, carefully designed and executed randomized experiments are ge…
Analytic continuation of Dirichlet series with almost periodic coefficients
Oliver Knill, John Lesieutre
We prove that an ordinary Dirichlet series with coefficients a(n)=g(n b) has an abscissa of convergence 0 if g is an odd 1-periodic, real-analytic function and b is Diophantine. We…
The Race Between Stars and Quasars in Reionizing Cosmic Hydrogen
Abraham Loeb
The cosmological background of ionizing radiation has been dominated by quasars once the Universe aged by ~2 billion years. At earlier times (redshifts z>3), the observed abundance…
Accurate path integration in continuous attractor network models of grid cells
Yoram Burak, Ila R. Fiete
Grid cells in the rodent entorhinal cortex display strikingly regular firing responses to the animal's position in 2-D space, and have been hypothesized to form the neural substrat…
Parametrization and Classification of 20 Billion LSST Objects: Lessons from SDSS
Z. Ivezic, T. Axelrod, A. C. Becker
The Large Synoptic Survey Telescope (LSST) will be a large, wide-field ground-based system designed to obtain, starting in 2015, multiple images of the sky that is visible from Cer…
Molecular gas in NUclei of GAlaxies (NUGA). XI. A complete gravity torque map of NGC4579: new clues on bar evolution
S. Garcia-Burillo, S. Fernandez-Garcia, F. Combes +6
We create a complete gravity torque map of the disk of the LINER/Seyfert 1.9 galaxy NGC4579. We quantify the efficiency of angular momentum transport and search for signatures of s…
The ACS Nearby Galaxy Survey Treasury I. The Star Formation History of the M81 Outer Disk
Benjamin F. Williams, Julianne J. Dalcanton, Anil C. Seth +16
The ACS Nearby Galaxy Survey Treasury (ANGST) is a large Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) treasury program to obtain resolved stellar photometry for a…
High-resolution X-ray spectroscopy of the evolving shock in the 2006 outburst of RS Ophiuchi
J. -U. Ness, J. J. Drake, S. Starrfield +9
The evolution of the 2006 outburst of the recurrent nova RS Ophiuchi was followed with 12 X-ray grating observations with Chandra and XMM-Newton. We present detailed spectral analy…
The number of occurrences of a fixed spread among n directions in vector spaces over finite fields
Le Anh Vinh
We study a finite analog of a problem of Erdos, Hickerson and Pach on the maximum number of occurrences of a fixed angle among n directions in three-dimensional spaces.
Constraints on the Local Sources of Ultra High-Energy Cosmic Rays
Eli Waxman, Abraham Loeb
Ultra high-energy cosmic rays (UHECRs) are believed to be protons accelerated in magnetized plasma outflows of extra-Galactic sources. The acceleration of protons to ~10^{20} eV re…
High redshift quasars in the COSMOS survey: the space density of z>3 X-ray selected QSOs
M. Brusa, A. Comastri, R. Gilli +19
We present a new measurement of the space density of high redshift (3.0<z<4.5), X-ray selected QSOs obtained by exploiting the deep and uniform multiwavelength coverage of the COSM…
Three-Dimensional Simulations of Magnetized Thin Accretion Disks around Black Holes: Stress in the Plunging Region
Rebecca Shafee, Jonathan C. McKinney, Ramesh Narayan +3
We describe three-dimensional general relativistic magnetohydrodynamic simulations of a geometrically thin accretion disk around a non-spinning black hole. The disk has a thickness…
Strategy abundance in 2x2 games for arbitrary mutation rates
Tibor Antal, Martin A. Nowak, Arne Traulsen
We study evolutionary game dynamics in a well-mixed populations of finite size, N. A well-mixed population means that any two individuals are equally likely to interact. In particu…
Efficient rare-event simulation for the maximum of heavy-tailed random walks
Jose Blanchet, Peter Glynn
Let be a sequence of i.i.d. r.v.'s with negative mean. Set and define . We propose an importance sampling algorithm to estimate the tail o…
First Results From The Taiwanese-American Occultation Survey (TAOS)
Z. -W. Zhang, F. B. Bianco, M. J. Lehner +22
Results from the first two years of data from the Taiwanese-American Occultation Survey (TAOS) are presented. Stars have been monitored photometrically at 4 Hz or 5 Hz to search fo…
Real-Time Calibration of the Murchison Widefield Array
D. A. Mitchell, L. J. Greenhill, R. B. Wayth +5
The interferometric technique known as peeling addresses many of the challenges faced when observing with low-frequency radio arrays, and is a promising tool for the associated cal…
Comment: Microarrays, Empirical Bayes and the Two-Groups Model
Carl N. Morris
Brad Efron's paper [arXiv:0808.0572] has inspired a return to the ideas behind Bayes, frequency and empirical Bayes. The latter preferably would not be limited to exchangeable mode…
