Searching for axions in the sky and the lab
Axion is a light particle arising in QCD as a solution to the strong CP problem and is considered to be one of the most promising dark matter candidate with […]

Berry phases, wormholes and factorization in AdS/CFT [Remote talk]
Within the AdS/CFT correspondence, the entanglement properties of the CFT are related to wormholes in the dual gravity theory. This gives rise to questions about the factorisation properties of the […]

[Journal Club] Right-handed neutrinos, TeV scale BSM neutral Higgs boson, and FIMP dark matter in an EFT framework
Abstract: We consider an effective field theory framework with three Standard Model (SM) gauge singlet right-handed neutrinos and an additional SM gauge singlet scalar field. The framework generates eV masses […]

CMB, LSS and the distance ladder: cosmic discordance? [Remote talk]
The Lambda-cold-dark-matter (LCDM) model has established itself as a fantastic (yet parametric) concordance model able to adjust a wide variety of cosmological observables — CMB, BBN, Large Scale Structure (LSS) […]

The Tadpole Problem [Remote talk]
I will discuss string theory compactifications where a large number of moduli is stabilized by fluxes. I will first present a conjecture which rules out the stabilization of all complex-structure moduli […]

Three-dimensional flux vacua from Type II supergravities
We discuss flux compactifications of Type IIA supergravity on G2 spaces with smeared O2/O6-planes down to three dimensions. We start by presenting the setup of allowed fluxes, the internal geometry, […]

Imprints of axion-like particles in photon spectra from galaxy clusters
Modulations of X-ray spectra from extragalactic sources might provide a signature of photons converting into axion-like particles (ALPs) when traversing a region with a large-scale magnetic field. A crucial unknown in these searches is the structure of the magnetic field considered. In this talk I discuss the impact of realistic models of the magnetic field on […]
