New g'r'i'z' Photometry of the NGC 5128 Globular Cluster System

We present new photometry for 323 of the globular clusters in NGC 5128 (Centaurus A), measured for the first time in the $g'r'i'z'$ filter system. The color indices are calibrated directly to standard stars in the $g'r'i'z'$ system and are used to establish the fiducial mean colors for the blue and red (low and high metallicity) globular cluster sequences. We also use spectroscopically measured abundances to establish the conversion between the most metallicity-sensitive colors ($(g'-r')_0$, $(g'-i')_0$) and metallicity, [Fe/H].Comment: 14 pages, 9 figures, accepted in A

Beyond Homoiousios and Homoousios: Exploring North American Indigenous Concepts of the Shalom Community of God (Chapter 2 of The Trinity Among the Nations)

The fourth-century battle over the interpretation of a single developed trinitarian theology laid the groundwork for numerous binary trajectories, with some resulting in Christian imperialism. Western Christianity\u27s early preoccupation with divine ontology, coupled with the military might of the Christian empire and the West\u27s inability to hold the mystery of God in tension, has beleaguered Christians and other monotheists for centuries. An Indigenous understanding of the divine shalom community may offer different choices that are perhaps closer to the constructed understandings of Trinity held by early followers of the Christ. In their various perceptions, early Jewish Christians recognized and acknowledged a place in their worldview for a trinitarian construct without the trappings of extrinsic categorization or the burden of ontological fixation. If we must talk of God in ontological terms, which again is beyond any of our comprehension, then perhaps the image of the community of the Creator, existing eternally in shalom relationality, can lead us beyond much of the former dialogue that has centered itself on ontological substance, and toward a better understanding of our own communal ontology
