13. IllustrisTNG: the new frontier to understand the co-evolution of (cold) dark matter and galaxies with cosmological simulations of structure formation

Dr Annalisa Pillepich (MPIA Heidelberg)

23/10/2018, 10:00

I will describe the numerical efforts to simulate galaxies with the moving-mesh code AREPO across an unprecedented range of halo masses, environments, evolutionary stages and cosmic times. In particular, I will focus on the IllustrisTNG project (www.tng-project.org), a series of three gravity+magnetohydrodynamics cosmological volumes (50, 100, 300 Mpc a side, respectively) in a LCDM cosmology...

14. Bounds on Dark Matter Annihilations from 21-cm data

Dr Paolo Panci (CERN)

In March 2018 the EDGES experiment has reported the discovery of an absorption feature in the 21-cm spectrum at redshift around 17. This measurement, if confirmed, is fundamental because can give us information about the epoch of reionization soon after the formation of first stars and galaxies. This talk is organised in three parts. In the first part I’ll present the EDGES experiment and the...

15. Dark matter heats up in dwarf galaxies

Pure dark matter structure formation simulations in LCDM predict that dwarf galaxies should inhabit dark matter halos that have steeply rising central density “cusps”. However, observations of nearby dwarf irregulars favour instead constant density dark matter “cores”. Many solutions to this cusp-core problem have been proposed, from modifications to the nature of dark matter to dark matter...

17. The LIGER method: light-cone using GR

Daniele Bertacca (Dipartimento di Fisica e Astronomia "Galileo Galilei" Universita' degli Studi di Padova via Marzolo 8, I-35131 Padova, Italy )

We introduce a method to create mock galaxy catalogs in redshift space including all gen- eral relativistic effects to linear order in the cosmological perturbations. We dub our method LIGER, a short for ‘light cones with general relativity’. LIGER takes a (N-body or hydrody- namic) Newtonian simulation as an input and outputs the distribution of galaxies in comoving redshift space. This...
