The NANOGrav 11-Year Data Set: Limits on Gravitational Wave Memory

K. Aggarwal, Z. Arzoumanian, P. T. Baker +58

The mergers of supermassive black hole binaries (SMBHBs) promise to be incredible sources of gravitational waves (GWs). While the oscillatory part of the merger gravitational wavef…

Partially Composite Dynamical Dark Matter

Yusuf Buyukdag, Keith R. Dienes, Tony Gherghetta +1

In this paper, we consider a novel realization of the Dynamical Dark Matter (DDM) framework in which the ensemble of particles which collectively constitute the dark matter are the…

Duty to Warn in Strategic Games

Pavel Naumov, Jia Tao

The paper investigates the second-order blameworthiness or duty to warn modality "one coalition knew how another coalition could have prevented an outcome". The main technical resu…

The NANOGrav 11-year Data Set: Constraints on Planetary Masses Around 45 Millisecond Pulsars

E. A. Behrens, S. M. Ransom, D. R. Madison +27

We search for extrasolar planets around millisecond pulsars using pulsar timing data and seek to determine the minimum detectable planetary masses as a function of orbital period.…

A pulsar-based timescale from the International Pulsar Timing Array

G. Hobbs, L. Guo, R. N. Caballero +56

We have constructed a new timescale, TT(IPTA16), based on observations of radio pulsars presented in the first data release from the International Pulsar Timing Array (IPTA). We us…

Non-Minimal Dark Sectors: Mediator-Induced Decay Chains and Multi-Jet Collider Signatures

Keith R. Dienes, Doojin Kim, Huayang Song +3

A preponderance of astrophysical and cosmological evidence indicates that the universe contains not only visible matter but also dark matter. In order to suppress the couplings bet…

The NANOGrav 11-Year Data Set: Evolution of Gravitational Wave Background Statistics

J. S. Hazboun, J. Simon, S. R. Taylor +60

An ensemble of inspiraling supermassive black hole binaries should produce a stochastic background of very low frequency gravitational waves. This stochastic background is predicte…

Constraining Dark-Matter Ensembles with Supernova Data

Aditi Desai, Keith R. Dienes, Brooks Thomas

The constraints on non-minimal dark sectors involving ensembles of unstable dark-matter species are well established and quite stringent in cases in which these species decay to vi…

Enlarging the Space of Viable Inflation Models: A Slingshot Mechanism

Keith R. Dienes, Jeff Kost, Brooks Thomas

The viability of a given model for inflation is determined not only by the form of the inflaton potential, but also by the initial inflaton field configuration. In many models, fie…

Relativistic Shapiro delay measurements of an extremely massive millisecond pulsar

H. Thankful Cromartie, Emmanuel Fonseca, Scott M. Ransom +24

Despite its importance to our understanding of physics at supranuclear densities, the equation of state (EoS) of matter deep within neutron stars remains poorly understood. Millise…

The Green Bank North Celestial Cap Pulsar Survey. IV: Four New Timing Solutions

R. J. Aloisi, A. Cruz, L. Daniels +40

We present timing solutions for four pulsars discovered in the Green Bank Northern Celestial Cap (GBNCC) survey. All four pulsars are isolated with spin periods between 0.26s a…
