The Star Planet Activity Research CubeSat (SPARCS) will be a 6U CubeSat devoted to photometric monitoring of M dwarfs in the far-ultraviolet (FUV) and near-ultraviolet (NUV) (160 and 280 nm respectively), measuring the time-dependent spectral slope, intensity and evolution of M dwarf stellar UV radiation. The delta-doped detectors baselined for SPARCS have demonstrated more than five times the in-band quantum efficiency of the detectors of GALEX. Given that red:UV photon emission from cool, low-mass stars can be million:one, UV observation of thes stars are susceptible to red light contamination. In addition to the high efficiency delta-doped detectors, SPARCS will include red-rejection filters to help minimize red leak. Even so, careful red-rejection and photometric calibration is needed. As was done for GALEX, white dwarfs are used for photometric calibration in the UV. We find that the use of white dwarfs to calibrate the observations of red stars leads to significant errors in the reported flux, due to the differences in white dwarf and red dwarf spectra. Here we discuss the planned SPARCS calibration model and the color correction, and demonstrate the importance of this correction when recording UV measurements of M stars taken by SPARCS.

It is the marvel of a sunset on the most ordinary day that can change life forever. In this Honors Project, I attempt to explore my innate fascination with beauty and the results of this relationship. This creative project aims to explore the five pillars that are responsible for the book of poems, Why Do We See Beauty?: The Human Event, the Tao Te Ching, Philosophy, Buddhism, and my relationship with God. These pillars have intertwined consistently throughout the past few years and the entire book of poems is a product of my engagement, integration, and synthesis with these components of my life. The creative project, Why Do We See Beauty?, consists of fifty-one poems that center around spirituality, truth, and the mystery of God; whether implicitly or explicitly stated, the poetry serves as a medium to wrestle with the truth in my life. Through a breakdown of these five pillars of my poetry and then the communication of key themes, texts, and ideas that are grounded in it, I hope to share my art from the past few years. What started in The Human Event during my first year at Barrett has evolved into an undergraduate creative project that shows how The Human Event became personal.

The Arizona Board of Education decides the science curricula for students K-6. The standards lack an in depth knowledge of marine life, marine science, ocean conservation, and more related topics. Through interviews with teachers, faculty, and research on ocean literacy and coral reefs, My Coral Reef Booklet assembles various learning activities to cater to students from a variety of education, financial and impairment backgrounds. My Coral Reef Booklet addresses coral reef basics and how students can play their part in coral reef conservation despite their location.

Gamma-ray bursts (GRBs) are a type of astrophysical transient resulting from the most energetic explosions known in the universe. The explosions occur in distant galaxies, and their bright initial emission may only last a few seconds. Colibri is a telescope being built at the San Pedro Martir Observatory in Baja, CA, MX with high sensitivity in order to study these events at a high redshift. Due to how quickly GRBs occur, it is essential to develop an image reduction pipeline that can quickly and accurately detect these events. Using existing image reduction software from Coatli, which was programmed and optimized for speed using python, numerous time trials were performed in order to determine if the pipeline meets the time requirements with various factors being adjusted. The goal of this experiment is for the telescope to respond to, capture, and reduce the images in under 3 minutes. It was determined that the reduction was optimized when the number of files to be reduced was set equal to 16 or higher by changing the batch number and the blank sky subtraction function was performed. As for the number of exposures, one can take up to four 30 second exposures or twenty 5 second exposures and reduce them in under 3 minutes.
