On ALP scenarios and GRB 221009A
Pierluca Carenza, M. C. David Marsh
The extraordinarily bright gamma-ray burst GRB 221009A was observed by a large number of observatories, from radio frequencies to gamma-rays. Of particular interest are the reporte…
How do Magnetic Field Models Affect Astrophysical Limits on Light Axion-like Particles? An X-ray Case Study with NGC 1275
James H. Matthews, Christopher S. Reynolds, M. C. David Marsh +2
Axion-like particles (ALPs) are a well-motivated extension to the standard model of particle physics, and X-ray observations of cluster-hosted AGN currently place the most stringen…
Astrophysical limits on very light axion-like particles from Chandra grating spectroscopy of NGC 1275
Christopher S. Reynolds, M. C. David Marsh, Helen R. Russell +4
Axions/axion-like particles (ALPs) are a well motivated extension of the Standard Model and are generic within String Theory. The X-ray transparency of the intracluster medium (ICM…
Physics potential of the International Axion Observatory (IAXO)
E. Armengaud, D. Attie, S. Basso +88
We review the physics potential of a next generation search for solar axions: the International Axion Observatory (IAXO). Endowed with a sensitivity to discover axion-like particle…
Primordial Non-Gaussianity
P. Daniel Meerburg, Daniel Green, Muntazir Abidi +175
Our current understanding of the Universe is established through the pristine measurements of structure in the cosmic microwave background (CMB) and the distribution and shapes of…
Hyperinflation generalised: from its attractor mechanism to its tension with the `swampland conjectures'
Theodor Bjorkmo, M. C. David Marsh
In negatively curved field spaces, inflation can be realised even in steep potentials. Hyperinflation invokes the `centrifugal force' of a field orbiting the hyperbolic plane to su…
