Mini-Workshop on Primordial Black Holes

Monday 25 Apr 2022, 12:30 → 19:00 Europe/Zurich

ULB

The goal of this mini-workshop, organized at ULB-Brussels, in the margins of the Solvay Workshop on Fundamental Physics with LISA, is to discuss recent developments in the field of primordial black holes.   A few talks are planned with a priority to young post-docs and PhD students, as well as some time for discussion.

The talks will be broadcasted on zoom: https://us02web.zoom.us/j/5283785114?pwd=cGtSelZ1KzRRM0NpQmlNaVVkcFVEQT09

 

12:30 → 14:00 Lunch

Speaker: Pierre Auclair (UCLouvain)

14:25 → 14:50 Simulation of Primordial Black Holes with large negative non-Gaussianity

Speaker: Albert Escrivà (ULB)

14:50 → 15:15 Peaks and primordial black holes: the effect of non-Gaussianity

Speaker: Sam Young (Leiden )

15:15 → 15:55 Primordial black holes: threshold prescription and QCD phase transition

Speaker: Ilia Musco (U. Roma)

15:55 → 16:25 Coffee Break

16:25 → 16:50 Constraints on asteroid-mass primordial black holes from capture by contracting protostellar clouds

16:50 → 17:15 Non-Cold Dark Matter from Primordial Black Hole Evaporation

Speaker: Quentin Decant (ULB)

17:15 → 18:00 Discussion

Three proposed topics:
- PBH formation at QCD transition with a varying equation of state
- Do clustered PBHs from QCD transition evade microlensing and CMB limits?
- What are Baby (Separate) Universe?
