The next seminar brought to you by the NASA Cosmic Origins Program’s Galaxies Science Interest Group (Galaxies SIG) will be on Tuesday October 3rd, 2023 at 1pm ET. We are going to get a theory perspective from Aaron Smith (UT Dallas) on how HWO can help uncover the coevolution of galaxies and their cosmic ecosystem via emission and absorption lines from galaxies. More information about the scientific topics of the Galaxies SIG can be found on their landing page.
The forthcoming Habitable Worlds Observatory (HWO) and Great Observatories Maturation Program (GOMAP) promise unparalleled opportunities for probing emission and absorption lines from galaxies. This talk will focus on the use of hydrodynamical simulations for generating robust line modeling predictions essential for HWO endeavors. I will discuss the merits and challenges of various approaches, hindering a community consensus on galaxy formation. Given the complexities of comparing simulations with different physical accuracy, numerical resolution, and population statistics, I advocate for advancing the state-of-the-art across multiple methodologies, ranging from generic templates to comprehensive radiative transfer calculations. Finally, I will highlight several scientific questions that stand to gain from GOMAP capabilities, emphasizing the role of simulations in providing insights and interpretations.
Seminar Schedule: Every first Tuesday of the month 1 – 2pm ET
