The NANOGrav Nine-Year Data Set: Measurement and Interpretation of Variations in Dispersion Measures
M. L. Jones, M. A. McLaughlin, M. T. Lam +21
We analyze dispersion measure (DM) variations of 37 millisecond pulsars in the 9-year NANOGrav data release and constrain the sources of these variations. Variations are significan…
The NANOGrav Nine-Year Data Set: Excess Noise in Millisecond Pulsar Arrival Times
M. T. Lam, J. M. Cordes, S. Chatterjee +22
Gravitational wave astronomy using a pulsar timing array requires high-quality millisecond pulsars, correctable interstellar propagation delays, and high-precision measurements of…
Kaluza-Klein Towers in the Early Universe: Phase Transitions, Relic Abundances, and Applications to Axion Cosmology
Keith R. Dienes, Jeff Kost, Brooks Thomas
We study the early-universe cosmology of a Kaluza-Klein (KK) tower of scalar fields in the presence of a mass-generating phase transition, focusing on the time-development of the t…
Dynamical Dark Matter from Strongly-Coupled Dark Sectors
Keith R. Dienes, Fei Huang, Shufang Su +1
Dynamical Dark Matter (DDM) is an alternative framework for dark-matter physics in which the dark sector comprises a vast ensemble of particle species whose decay widths are balanc…
Boxes, Boosts, and Energy Duality: Understanding the Galactic-Center Gamma-Ray Excess through Dynamical Dark Matter
Kimberly K. Boddy, Keith R. Dienes, Doojin Kim +3
Many models currently exist which attempt to interpret the excess of gamma rays emanating from the Galactic Center in terms of annihilating or decaying dark matter. These models ty…
Lines and Boxes: Unmasking Dynamical Dark Matter through Correlations in the MeV Gamma-Ray Spectrum
Kimberly K. Boddy, Keith R. Dienes, Doojin Kim +3
Identifying signatures of dark matter at indirect-detection experiments is generally more challenging for scenarios involving non-minimal dark sectors such as Dynamical Dark Matter…
Localized deformation for initial data sets with the dominant energy condition
Justin Corvino, Lan-Hsuan Huang
We consider localized deformation for initial data sets of the Einstein field equations with the dominant energy condition. Deformation results with the weak inequality need to be…
PSR J1024-0719: A Millisecond Pulsar in an Unusual Long-Period Orbit
D. L. Kaplan, T. Kupfer, D. J. Nice +32
PSR J10240719 is a millisecond pulsar that was long thought to be isolated. However, puzzling results concerning its velocity, distance, and low rotational period derivative hav…
Proto-Cooperation: group hunting sailfish improve hunting success by alternating attacks on grouping prey
James E Herbert-Read, Pawel Romanczuk, Stefan Krause +8
We present evidence of a novel form of group hunting. Individual sailfish (Istiophorus platypterus) alternate attacks with other group members on their schooling prey (Sardinella a…
The NANOGrav Nine-year Data Set: Mass and Geometric Measurements of Binary Millisecond Pulsars
Emmanuel Fonseca, Timothy T. Pennucci, Justin A. Ellis +17
We analyze 24 binary radio pulsars in the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) nine-year data set. We make fourteen significant measurements of S…
From Spin Noise to Systematics: Stochastic Processes in the First International Pulsar Timing Array Data Release
L. Lentati, R. M. Shannon, W. A. Coles +80
We analyse the stochastic properties of the 49 pulsars that comprise the first International Pulsar Timing Array (IPTA) data release. We use Bayesian methodology, performing model…
The International Pulsar Timing Array: First Data Release
J. P. W. Verbiest, L. Lentati, G. Hobbs +89
The highly stable spin of neutron stars can be exploited for a variety of (astro-)physical investigations. In particular arrays of pulsars with rotational periods of the order of m…
Isotropic matroids III: Connectivity
Lorenzo Traldi, Robert Brijder
The isotropic matroid of a graph is a binary matroid, which is equivalent to the isotropic system introduced by Bouchet. In this paper we discuss four notions of co…
The NANOGrav Nine-year Data Set: Monitoring Interstellar Scattering Delays
Lina Levin, Maura A. McLaughlin, Glenn Jones +22
We report on an effort to extract and monitor interstellar scintillation parameters in regular timing observations collected for the NANOGrav pulsar timing array. Scattering delays…
Incipient triple point for adsorbed xenon monolayers: Pt(111) versus graphite substrates
Anthony D. Novaco, L. W. Bruch, Jessica Bavaresco
Simulation evidence of an incipient triple point is reported for xenon submonolayers adsorbed on the (111) surface of platinum. This is in stark contrast to the "normal" triple poi…
