Galaxy Dynamics in the Gaia Era

Date: 23 June 2019 to 28 June 2019
Location: Shanghai, China, Nanjing
Contact: Juntai Shen (jshen@shao.ac.cn)
Coordinating division: Division H Interstellar Matter and Local Universe
Chair of SOC: Juntai Shen (Shanghai Astronomical Observatory)
Chair of LOC: Juntai Shen (Shanghai Astronomical Observatory)

 

Topics

- The structure, dynamics, and assembly history of the Milky Way galaxy in the Gaia era
- Dynamical processes in galaxy formation and evolution, including internal secular evolution and mergers
- Dynamical modelling of galaxies to measure the mass profiles of baryons and dark components with the on-going large IFU surveys
- Dynamics of disk galaxies including spiral structure, bars, bulges, and
- The role of gas in galaxy evolution

 

Rationale

Galaxy dynamics is directly connected with the formation of galaxies, their internal evolution, structure, interactions, and also impacts studies of groups and clusters of galaxies, star formation, chemical evolution, gas dynamics both within and around galaxies, etc. Major photometric and spectroscopic surveys, such as 2MASS, SDSS, RAVE, PanSTARRS, LAMOST, APOGEE, etc. have delivered detailed information about the Milky Way, and they are soon to be dwarfed by LSST and Gaia. Much theoretical progress has also been made on internal evolution of galaxies, especially secular changes, on the role of bars, central massive objects, the role of gas, etc. Despite all this activity, there has not been a major international conference on the dynamics of galaxies for more than a decade.

We suggest it will be held under the auspices of Divisions H (Interstellar Matter and Local Universe, President Bruce Elmegreen) and J (Galaxies and Cosmology, President Claus Lietherer), who are both supportive.

The aim will be to bring together the world's leading experts to review and present recent advances in galaxy dynamics, and to foster a new generation of galactic dynamicists especially in developing countries. The main topics to be addressed include:

- The structure, dynamics, and assembly history of the Milky Way galaxy in the Gaia era
- Dynamical processes in galaxy formation and evolution, including internal secular evolution and mergers
- Dynamical modelling of galaxies to measure the mass profiles of baryons and dark components with the on-going large IFU surveys
- Dynamics of disk galaxies including spiral structure, bars, bulges, and
- The role of gas in galaxy evolution

James Binney, Scott Tremaine and Jerry Sellwood have all agreed to participate in the proposed symposium and they, together with perhaps Ken Freeman, Francoise Combes, John Kormendy, and others will be consulted about the make up of the SOC. Selection of key speakers will be made after the SOC is convened.
