    In this Work in Progress (WIP) paper, we detail the initial steps taken to study NSF grants that seek to benefit the LGBTQ+ community through understanding their experiences or by working toward their full participation in society. To this end, we have identified active and expired NSF grants that either advance knowledge of LGBTQ+ experiences or offer some benefit to the community (e.g., tailored professional development, addressing and changing the marginalizing culture of STEM, etc.). We then developed a coding scheme to categorize these grants with respect to the level of positive impact they have on the LGBTQ+ community using modified Intellectual Merit and Broader Impacts criteria that parallels the NSF’s own criteria for evaluating proposals. The work established in this paper to identify and code LGBTQ-focused NSF grants will next allow us to extract trends in these grants over a period of over 4 decades.

  2. Abstract The results of gamma-ray observations of the binary system HESS J0632 + 057 collected during 450 hr over 15 yr, between 2004 and 2019, are presented. Data taken with the atmospheric Cherenkov telescopes H.E.S.S., MAGIC, and VERITAS at energies above 350 GeV were used together with observations at X-ray energies obtained with Swift-XRT, Chandra, XMM-Newton, NuSTAR, and Suzaku. Some of these observations were accompanied by measurements of the H α emission line. A significant detection of the modulation of the very high-energy gamma-ray fluxes with a period of 316.7 ± 4.4 days is reported, consistent with the period of 317.3 ± 0.7 days obtained with a refined analysis of X-ray data. The analysis of data from four orbital cycles with dense observational coverage reveals short-timescale variability, with flux-decay timescales of less than 20 days at very high energies. Flux variations observed over a timescale of several years indicate orbit-to-orbit variability. The analysis confirms the previously reported correlation of X-ray and gamma-ray emission from the system at very high significance, but cannot find any correlation of optical H α parameters with fluxes at X-ray or gamma-ray energies in simultaneous observations. The key finding is that the emission of HESS J0632 + 057 in the X-ray and gamma-ray energy bands is highly variable on different timescales. The ratio of gamma-ray to X-ray flux shows the equality or even dominance of the gamma-ray energy range. This wealth of new data is interpreted taking into account the insufficient knowledge of the ephemeris of the system, and discussed in the context of results reported on other gamma-ray binary systems.
