3 December 2020 – 4 December 2020 all-day Australia/Perth Timezone

Title: “Linking the Galactic and Extragalactic: stellar dynamics and stellar populations of the Milky Way and its siblings”

The online meeting will consist of a format with:

• Pre-recorded contribed talks, made available a week before the online meeting.
• An online forum for questions and discussions about the pre-recorded talks.
• 2 days with live invited talks and four discussion sessions led by the SOC via Zoom. Two session will be at 8-10am and two at 8-10pm Australian Eastern Daylight Time, accommodating various international timezones.



Our Milky Way is by far the best­ studied galaxy in the Universe, and it has long been regarded as a benchmark for understanding disk galaxies. We have made major leaps in our understanding of the Galaxy in the last few years, enabled by Gaia, APOGEE, GALAH, and LAMOST. However, the Milky Way is only one galaxy, and trying to understand the complex processes of galaxy formation and evolution from a single object is extremely challenging.

In this conference we aim to link Galactic and Extragalactic research, both of which bring unique perspectives to understanding how disk galaxies formed. The recent wealth of detailed Milky Way measurements from GALAH, APOGEE, LAMOST, and Gaia, combined with results from spatially resolved spectroscopic surveys such as SAMI, MaNGA, CALIFA, and with VLT­-MUSE, make this the ideal time to link Galactic and extragalactic research. Crucial in this discussion are the recent results from large cosmological and Milky Way zoom in simulations that show that the Galaxy might not be the ideal template for understanding disk formation as previously thought.

The four key topics for the meeting will be the stellar dynamics and populations of the Milky Way and the stellar dynamics and populations of extragalactic galaxies, and an extra topic dedicated to comparing the different disciplines.
