Finite Populations & Finite Time: The Non-Gaussianity of a Gravitational Wave Background

William G. Lamb, Jeremy M. Wachter, Andrea Mitridate +5

Strong evidence for an isotropic, Gaussian gravitational wave background (GWB) has been found by multiple pulsar timing arrays (PTAs). The GWB is expected to be sourced by a finite…

Deep Neural Emulation of the Supermassive Black-hole Binary Population

Nima Laal, Stephen R. Taylor, Luke Zoltan Kelley +13

While supermassive black-hole (SMBH)-binaries are not the only viable source for the low-frequency gravitational wave background (GWB) signal evidenced by the most recent pulsar ti…

More accurate gravitational wave backgrounds from cosmic strings

Jeremy M. Wachter, Ken D. Olum, Jose J. Blanco-Pillado

We derive a general procedure for calculating the gravitational wave background (GWB) from cosmic string loops whose typical shape evolves over time, as in gravitational backreacti…

Numerical gravitational backreaction on cosmic string loops from simulation

Jeremy M. Wachter, Ken D. Olum, Jose J. Blanco-Pillado +2

We report on the results of performing computational gravitational backreaction on cosmic string loops taken from a network simulation. The principal effect of backreaction is to s…

Gravitational waves from cosmic strings in LISA: reconstruction pipeline and physics interpretation

Jose J. Blanco-Pillado, Yanou Cui, Sachiko Kuroyanagi +6

We initiate the LISA template databank for stochastic gravitational wave backgrounds sourced by cosmic strings. We include two templates, an analytical template, which enables more…

Labor-based grading practices in the physics classroom

Jeremy M. Wachter

I describe the assessment framework of labor-based contract grading (LBCG). In a labor-based grading scheme, the time and effort ("labor") a student spends on an assignment determi…
