Title: Beyond LCDM: New constraints on new components Abstract: Are dark matter and dark energy the only cosmological constituents that lie beyond the Standard Model? It has been suggested that […]
Title: Stars under Einstein’s microscope: strong gravitational lensing near caustics Abstract: Rich clusters of galaxies are the largest gravitational magnifiers in the Universe. One of the most interesting gravitational lensing […]
Title: The hyperbolic tale of GW190521 Abstract: I will discuss the most enigmatic signal observed by the LIGO-Virgo-Kagra collaboration to date, GW190521, and the possibility that it was generated by […]

Title: “Higgs-Confinement Transitions in QCD from Symmetry Protected Topological Phases” Abstract: In gauge theories with fundamental matter, such as QCD, there is typically no sharp way to distinguish confining and […]
Title: de Sitter as an Axion Detector Abstract: Axions, scalar fields with compact field spaces, are some of the most well-motivated candidates for physics beyond the Standard Model. In this […]
Title: "Towards Dark Ages with LuSEE-Night" plus "large scale isocurvature fluctuations and the Hubble tension"
Title: Gravitational Wave Symphony from Oscillating Spectator Scalar Fields Abstract: Spectator scalar fields can be generically present in the early Universe, and are potentially dark matter candidates. We investigate the […]

TITLE: Impact of primordial magnetic fields on matter power spectrum ABSTRACT: Primordial magnetic fields (PMFs) offer a simple explanation for the origin of galactic magnetic fields as well as of […]
TITLE: CMB limits on decaying dark matter: going beyond the ionization threshold ABSTRACT: The temperature and polarization anisotropies of the cosmic microwave background (CMB) have been used to set constraints […]
