[Drand] Scientific Fika – Friday October 7th 16:00 Room Mega – Florian Kühnel ‘Aspects of Primordial Black Holes’

[Nikki Arendse]

Dear Juniors,

It is my pleasure to announce this week's Scientific Fika. Join us on Friday the 7th of October at 16:00 for fika and a great talk by Florian Kühnel, an expert on primordial black holes who's visiting us from Munich.

Aspects of Primordial Black Holes


Primordial black holes are black holes that might have formed in the early Universe. Their masses potentially span a range from as low as the Planck scale up to many orders of magnitude above the solar mass. This, in particular, includes black holes with mass and spin comparable to those discovered by LIGO/Virgo. These may well be primordial in nature, which could also be true for certain confirmed microlensing events in the planetary-mass range as well as for the seeds for the super-massive black holes in galactic centres. After a general introduction to primordial black holes, I will discuss observational hints for their existence on multiple scales. I will highlight one particular PBH formation mechanism, which we recently developed, and which is not plagued by exponential fine-tuning like most other scenarios. Here, primordial black hole formation is induced by confinement of heavy quarks. I will discuss phenomenological features of this new mechanism. If time permits, I will discuss an entirely new property of black holes which we recently discovered -- vorticity.


Place: NORDITA Floor 6 - Room Mega (in-person only).
Address: AlbaNova University Center, Hannes Alfvéns väg 12
Please put this date in your calendar and come to discuss interesting science.

We're looking forward to seeing you!
Nadia, Guilherme and Nikki
