[Astronomy seminar] Astronomy Department Seminar - October 22nd Azadeh Fattahi

[Astronomy seminar announcements]

Hello

On Friday the 22nd we have the next astronomy Seminar with Azadeh 
Fattahi (Durham University) speaking at 10:30 via Zoom.

*The build-up of the Milky Way's halo*


Abstract: The hierarchical nature of galaxy formation in the standard 
model of cosmology (LCDM) predicts a diffuse stellar halo component 
around Milky Way-mass galaxies, formed from the accretion and disruption 
of dwarf galaxies. Using cosmological hydrodynamical simulations, I will 
discuss the radial build up of stellar halos from the accreted dwarfs 
and will connect these results with recent findings from the Gaia 
mission related to the major event in the formation history of the Milky 
Way (Gaia-Enceladus-Sausage). I will discuss whether this event is 
unusual and whether it has any implications for dark matter distribution 
and dark matter direct detection experiments.

We are trying something new this year with leaving the Zoom call open 
after the formal hour of the seminar is up to allow the speaker, if they 
wish, to chat informally with anyone who is interested.

Thanks

Chris and Tine
