IAG-USP's Weekly Astronomy Seminar - Wednesday, June 21, 2023 @ 14:00 (UTC-3)
Title: Nuclei of the Milky Way morphological twins (MWMT) of the DIVING 3D survey
Presenter: Patricia da Silva - IAG-USP, BR

Abstract: How the nuclei of galaxies that are similar to ours look like? Does the Milky Way nucleus, that has an inactive supermassive black hole, follow the trend of its twins? I will present the sample nuclei of galaxies that have the same morphological type as the Milky Way (SABbc and SBbc). This sample is from the Deep IFS View of Nuclei of Galaxies (DIVING 3D) survey, which has the goal of observing nuclei of galaxies of the southern hemisphere with the B band magnitude less than 12 and galactic latitude greater than 15 degrees. The survey comprises 170 galaxies, resulting optical data cubes with high spatial resolution. The sample of the MWMT comprises 15 galaxies, whose distances varies from 26.4 Mpc to 8.5 Mpc. In this project we study the emission of the nuclear region, the gas kinematics, the stellar kinematics and stellar archaeology. We also complement the study with other data in order to draw general scenarios of the phenomena we observe, as much as possible. I will talk about the main results and the future plans of this project and the DIVING3D survey.
