Three poems by A.C.S
No full textThis article was originally published in The Prophet -- a journal created by and for the students at the Boston University School of Theology (BUSTH) to amplify the voices of STH students by promoting and sharing a range of perspectives on matters of concern including, but not limited to, spiritual practices, faith communities and society, the nature of theology, and current affairs. It serves as a platform for STH students to share their academic work, theological reflections, and life experiences with one another and the wider community.Poems by A.C.S.

A Water Vapor Radiometer for the CO Mapping Array Project (COMAP)
No full textThe CO Mapping Array Project (COMAP) is a carbon monoxide (CO) line intensity mapping experiment using a 19-feed 26-34 GHz focal plane spectrometer array on a 10.4 m dish at the Owens Valley Radio Observatory. We are developing a water vapor radiometer (WVR) that continuously measures the temporal variability of the atmosphere's water vapor content along the telescope's line of sight to better calibrate the COMAP science data. The WVR is designed to monitor the rotational transition line of water vapor around 22.2 GHz, with a spectral measurement between 18 and 26 GHz and a measurement of continuum at 28-30 GHz. Here we describe the COMAP WVR instrument system. © 2023 USNC-URSI
A general tool for determining the asymptotic spectral distribution of Hermitian matrix-sequences
No full textWe consider sequences of Hermitian matrices with increasing dimension, and we provide a general tool for determining the asymptotic spectral distribution of a ‘difficult’ sequence {An}n from the one of ‘simpler’ sequences {Bn,m}n that approximate {An}n when m → ω. The tool is based on the notion of an approximating class of sequences (a.c.s.), which was inspired by the work of Paolo Tilli and the second author, and it is applied here in a more general setting. An a.c.s.-based proof of the famous Szegö theorem on the spectral distribution of Toeplitz matrices is finally presented
