The structure of thick discs in nearby galaxies by Dr Marie Martig
Please try to arrive at or before 15:00
Post Talks Refreshments: Physics C36
Abstract:
Thick disks are ubiquitous in nearby spiral galaxies, and many mechanisms have been proposed to explain their formation. I will show how, in simulated galaxies, thick disks arise from the superposition of mono-age populations (MAPs). I will discuss the connection between the properties of the MAPs and the global structure of thick disks, in particular their shape and their radial age gradient. I will also show how this can be linked with a galaxy’s recent merger history: mergers create gaps in the vertical structure of MAPs, and give rise to thick disks that are clearly distinct from thin disks. I will finally present results on the age structure of the Milky Way and a few nearby galaxies. I will end the talk with an introduction to the GECKOS survey, a new VLT/MUSE large programme targeting 35 nearby edge-on galaxies.
