The Colourful Past and Dark Side of Galaxies Unveiled Through Population-dynamics of Their Stars

11:30 am – 12:30 pm (CDT)

Speaker: Glenn van de Ven (University of Vienna)Host: Jonelle Walsh

Driven by gravity, galaxies continuously grow through accretion of smaller systems. Stellar streams are nice illustrations of this hierarchical build-up, but the accreted stars quickly disperse. I will present advanced dynamical models that can convert the observed positions and velocities of stars to phase-space quantities like energy and angular momen... read more  »

Dance of the Milky Way and the LMC

11:30 am – 12:30 pm (CDT)Streaming Live

Speaker: Denis Erkal (University of Surrey)Host: Jonelle Walsh

The LMC is the largest satellite of our Galaxy and has a total mass roughly 1/6th that of the Milky Way. In this talk, I will review the multiple lines of evidence for the LMC being so massive and then focus on the substantial effect it has on our Galaxy. In particular, I will discuss its effect on stellar streams, the stellar halo, and orbits of satel... read more  »

Bold Nuclei in Old Galaxies

11:30 am – 12:30 pm (CDT)Streaming Live

Speaker: Decker French (University of Illinois at Urbana-Champaign)Host: Stephanie Ho

The evolution of galaxies is fundamentally connected to the evolution of their central black holes. The large-scale environment of the host galaxy’s gas reservoir, star formation rate, and merger history affect the rate at which stars and gas can be accreted onto the central supermassive black hole. In response, accretion energy can regulate and u... read more  »

Stars and Dust: an Unavoidable and Complex Interplay Dust Obscuration and Attenuation Laws in Galaxies

11:30 am – 12:30 pm (CDT)Streaming Live

Speaker: Véronique Buat (Aix-Marseille Université)Host: Stephanie Ho

The very complex interplay between dust and stellar emission is reflected by the diversity of configurations: the contrast is striking between organized grand design spirals with regular distributions of each component and Submillimeter Galaxies (SMG) observed with HST and ALMA, and exhibiting a clear spatial disconnection between both stellar and dust ... read more  »
