The Minimum Amount of Stars a Galaxy Will Form

We present an analysis of the atomic hydrogen and stellar properties of 38 late-type galaxies in the local Universe covering a wide range of HI mass-to-light ratios (M_HI/L_B), stellar luminosities, and surface brightnesses. From these data we have identified an upper envelope for the M_HI/L_B as a function of galaxy luminosity. This implies an empirical relation between the minimum amount of stars a galaxy will form and its initial baryonic mass. While the stellar mass of a galaxy seems to be only loosely connected to its baryonic mass, the latter quantity is strongly linked to the galaxy's dynamical mass as it is observed in the baryonic Tully-Fisher relation. We find that dwarf irregular galaxies with generally high M_HI/L_B-ratios follow the same trend as defined by lower M_HI/L_B giant galaxies, but are underluminous for their rotation velocity to follow the trend in a stellar mass Tully-Fisher relation, suggesting that the baryonic mass of the dwarf galaxies is normal but they have failed to produced a sufficient amount of stars. Finally, we present a three dimensional equivalent to the morphology-density relation which shows that high M_HI/L_B galaxies preferentially evolve and/or survive in low-density environments. We conclude that an isolated galaxy with a shallow dark matter potential can retain a large portion of its baryonic matter in the form of gas, only producing a minimum quantity of stars necessary to maintain a stable gas disk.Comment: 37 Pages, 7 Figures.

1987 Commencement Address: Sen. Bill Bradley (D-New Jersey)

Sen. Bill Bradley, U.S. senator from New Jersey, a former star basketball player for the New York Knickerbockers and a Rhodes Scholar, will receive an honorary degree, Doctor of Laws, from the College of the Holy Cross and address this year’s graduates during the College’s Commencement ceremonies on Friday, May 29 at 10:30 a.m. on the campus. Bradley earned his indergraduate degree in 1965 at Princeton University, where he was an All American basketball player. He was also a standout on the victorious U.S. Olympic basketball team in 1964. Bradley turned down offers from professional teams to accept a Rhodes Scholarship and studied for two years at Oxford University in England, where he earned a Master\u27s degree. He was signed by the Knicks to a four-year contract begining in the 1967-68 season and retired from professional basketball in 1977. Bradley was elected as a U.S. senator (D) from New Jersey and was re-elected in 1984. He is the author of a book, Life on the Run.https://crossworks.holycross.edu/commence_address/1014/thumbnail.jp

Loggerhead turtle (Caretta caretta) nest predation at Cape Range National Park

Most of the existing sea turtle populations worldwide are in decline. In particular, loggerhead turtles (Caretta caretta) are listed as endangered and loggerhead nesting populations in Eastern Australia have declined by 86% since the 1970s. However, whilst Eastern Australian loggerhead populations have been extensively studied and monitored, not much is known about the Western Australian nesting population

Somewhere Between Fiction and Fiction: Disentangling Partial-Geometric Narratives in the Cinema of Hong Sang-soo

Predominantly linear narrative arrangements used to direct the spectator's comprehension are but one of many options made available to filmmakers. Opposing this convention, the films of South Korean director Hong Sang-soo are characterized by their complex narratives as much as the romantic triangles that inhabit them. This thesis addresses the “optional path” narratives observable in Hong's films, which deny the audience the ability to reconstruct an objective, verifiable timeline. Whereas established theories of film narratives foreground the limitations placed on storytelling in order to guide comprehension, key works in Hong's cinema will be understood to adopt a “partial-geometric” model that emphasizes the agency of the spectator in creating meaning in the film text. A style-based narratological approach, operating under Formalist assumptions, will be interrogated for the fissures that emerge when it is applied against these texts. The objects of study are understood as realizing multiple diegeses, or story worlds, the boundaries of which are made speculative through the use of space. Although building upon the existing narratological insights of key scholars David Bordwell and Edward Branigan, this thesis will instead distance itself from limiting narrative frameworks in favor of optionality. The spectator is able to attribute or disarticulate the “truth value” of key events, and is encouraged to recognize the unlimited narrative arrangements and their own subjective agency. This thesis will also make initiatives to extend its insights beyond the borders of Hong's filmography, recognizing film festivals as a discursive site for expanding narrative models
