Description

Plenary talks by invited speakers

7. Astrophysics and fundamental physics from high-energy cosmic messengers

Mauricio Bustamante (Niels Bohr Institute)

14/11/2022, 09:00

Astroparticle physics

Plenary invited presentation

High-energy gamma rays, cosmic rays, and neutrinos are messengers of violent astrophysical phenomena and probes of fundamental physics at extreme energies. Tremendous experimental advance has unlocked vast potential for progress in both directions. First, I will present the basics of high-energy particle production at astrophysical sites. Then I will showcase the main lessons learned and...

Astroparticle physics

Plenary invited presentation

High-elevation particle detectors have opened a new observational window in Astronomy, significantly increasing the number of detected gamma-ray sources in the very- to ultra-high energy range. In particular, these instruments were able to achieve unprecedented sensitivity above 100 TeV and detected gamma-ray emission from sources up to PeV. The recent successes have all been obtained from the...

Almost half a century after it was predicted, the LHC delivered the Higgs boson in spectacular style. Over the next 15-20 years, the machine and its luminosity upgrade will continue to enable ATLAS and CMS to make great strides in understanding the Higgs-boson’s properties. But to fully explore the scalar sector and its possible connections with the SM’s most mysterious features, and thus to...

Plenary invited presentation

To what extent are all astrophysical, dark, compact objects both black holes (BHs) and described by the Kerr geometry? We embark on the exercise of defying the universality of this remarkable idea, often called the "Kerr hypothesis". After establishing its rationale and timeliness, we define a minimal set of reasonability criteria for alternative models of dark compact objects. Then, as proof...

CERN's Large Hadron Collider has just started Run 3 of data collection. And in 2029 it will commence the High-Luminosity (HL-LHC) phase of running - expected to last almost a decade. The amount of data collected during the HL-LHC is unprecedented in High Energy Physics. Collecting, processing, calibrating and analyzing that volume of data to the precision required is forcing the community to...
