Description:

We welcome scientists to participate in a Splinter Session at the 241st Meeting of the American Astronomical Society organized by the Science Operations Center for the Nancy Grace Roman Space Telescope (NGRST or Roman). If you are attending the AAS241, you may add this to your schedule using its entry in the Block Program Schedule. Registration for the AAS241 meeting is not required to participate in the session virtually either through synchronous or asynchronous options.

Splinter Session Abstract:

The Roman Space Telescope will provide HST-like spatial resolution in the optical and near-infrared, but with a field of view 100 times larger than HST. Even for single pointings, this provides data sets comparable to large survey projects with previous generation space-based observatories. Roman's large field-of-view will also quickly map the most nearby galaxies with resolved stars. Its superb astrometric capabilities will allow us to measure galaxy growth across space and time with unprecedented detail. Complementary, studies that map stellar populations with Roman in the most nearby galaxies will teach us valuable lessons to connect to observations and simulations of the early Universe. ALMA and JWST studies of galaxies probe the build-up of stellar mass at high redshift and, in complement, Roman will provide statistically significant samples to study how efficient metal production is during the most vigorous stages of galactic growth. The goal of this session is to bring together expertise from the local and more distant Universe to articulate how studies of the expanding horizon of the nearby Universe, with Roman, can be connected to our understanding of the most distant objects.

Discussion on Science Community Preparations for Roman Science

The following discussion prompts will be used:

  1. Roman will provide HST-like imaging over large areas in the IR; this in itself will be transformative for nearby galaxy studies. What current and upcoming instruments (or surveys) will complement Roman, particularly in the science area of nearby galaxies? Are there limitations or hurdles to overcome in what currently exists or is planned?

  2. In addition to thinking about the scientific capabilities of Roman, are there ways that we can strengthen, expand, and prepare the our science community in preparation for Roman?
    1. Are there conferences, workshops, or community-building events we could organize in the next three years that would be engaging for people working in this science area?
    2. Are there open source packages the community might want to rally around and add to, or build complementary packages for, to support doing science in nearby galaxies with Roman?
    3. Is there something that will be needed for nearby galaxies work that is entirely missing in the open-source software ecosystem?
