 Jillian M. Scudder, Assistant Professor of Physics; Sara L. Ellison; Loubna El Meddah El Idrissi; Henry Poetrodjojo. Conversions between gas-phase metallicities in MaNGA. Monthly Notices of the Royal Astronomical Society (submitted 10 August, 2021; accepted 12 August 2021)  Pre-publication access: arXiv: 2108.04934  20 pages, 14 figures, 4 tables. Supplementary material available online

From the abstract: We present polynomial conversions between each of 11 different strong line gas-phase metallicity calibrations, each based on ∼ 1.1 million star-forming spaxels in the public Sloan Digital Sky Survey (SDSS) Data Release 15 (DR15) Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey.

From the abstract: "We extract interstellar scintillation parameters for pulsars observed by the NANOGrav radio pulsar timing program.  ...For most pulsars for which scattering delays are measurable, we find that time-of-arrival uncertainties for a given epoch are larger than our scattering delay measurements, indicating that variable scattering delays are currently subdominant in our overall noise budget but are important for achieving precisions of tens of nanoseconds or less."

Islam, M., Deeti, S., Kamhi, J. Frances, & Cheng, K. (2021). Minding the gap: learning and visual scanning behaviour in nocturnal bull ants. Journal of Experimental Biology, 224(14), jeb242245.

From the abstract: "Insects possess small brains but exhibit sophisticated behaviour, specifically their ability to learn to navigate within complex environments. To understand how they learn to navigate in a cluttered environment, we focused on learning and visual scanning behaviour in the Australian nocturnal bull ant, Myrmecia midas, which are exceptional visual navigators."
