Production thesis : A funny thing happened on the way to the forum by Burt Shevelove, Larry Gelbart and Stephen Sondheim

According to the authors, A Funny Thing Happened on the Way to the Forum is based on the plays of Plautus. The director, upon choosing this musical as his production thesis, made a study of the comedies upon which the musical was based. The study begins with the influences on Plautine writing and considers the indigenous drama of Rome prior to and including 240 B.C. as described by Livy. The director analyzed the influence of Greek New Comedy on Roman drama as well as the influence of the Roman stage on Plautus and his writing. The personality and personal life of Plautus were also analyzed in considering the influences on Plautine style. From these stylistic considerations, the director related the significant influences of Plautus on the modern musical in the areas of dialogue, plot structure, staging, and music

Multi-Messenger Gravitational Wave Searches with Pulsar Timing Arrays: Application to 3C66B Using the NANOGrav 11-year Data Set

When galaxies merge, the supermassive black holes in their centers may form binaries and, during the process of merger, emit low-frequency gravitational radiation in the process. In this paper we consider the galaxy 3C66B, which was used as the target of the first multi-messenger search for gravitational waves. Due to the observed periodicities present in the photometric and astrometric data of the source of the source, it has been theorized to contain a supermassive black hole binary. Its apparent 1.05-year orbital period would place the gravitational wave emission directly in the pulsar timing band. Since the first pulsar timing array study of 3C66B, revised models of the source have been published, and timing array sensitivities and techniques have improved dramatically. With these advances, we further constrain the chirp mass of the potential supermassive black hole binary in 3C66B to less than $(1.65\pm0.02) \times 10^9~{M_\odot}$ using data from the NANOGrav 11-year data set. This upper limit provides a factor of 1.6 improvement over previous limits, and a factor of 4.3 over the first search done. Nevertheless, the most recent orbital model for the source is still consistent with our limit from pulsar timing array data. In addition, we are able to quantify the improvement made by the inclusion of source properties gleaned from electromagnetic data to `blind' pulsar timing array searches. With these methods, it is apparent that it is not necessary to obtain exact a priori knowledge of the period of a binary to gain meaningful astrophysical inferences.Comment: 14 pages, 6 figures.

This upper limit provides a factor of 1.6 improvement over previous limits and a factor of 4.3 over the first search done.
