2018.10.09 GBT Astro2020 Galaxies Telecon Telecon Participants: --------------------- D.J. Pisano Kevin Harrington David Frayer Jay Lockman GBT related white papers: Adam Leroy (PI) plans to update/modify his ngVLA white paper for the GBT: molecular gas in nearby galaxies (W-band) D.J. Pisano (PI): Low N(HI) for the next decade (L-band) Kevin Harrington(PI): Mapping the early large-scale molecular structures from which galaxies form (Ka-band) Future GBT/GBO instrumentation was discussed. In particular, a new 14K Lband system, a potential phase-array-feed system for Ka-band, and dual-polarization W-band system that works up to 116GHz, as well as the GB Array. https://greenbankobservatory.org/science/future-instrumentation/ The science white papers will help drive observatory instrumentation priorities in the coming decade. If others are planning potential science white papers with a GBT component, let us know so we can track them.
