Light scalar explanation for 18 TeV GRB 221009A
Shyam Balaji, Maura E. Ramirez-Quezada, Joseph Silk +1
Recent astrophysical transient Swift J1913.1+1946 may be associated with the -ray burst GRB 221009A. The redshift of this event is . Very high-energy -rays (up…
Discovery of a new extragalactic source population of energetic particles
Anthony M. Brown, Celine Bœhm, Jamie Graham +3
We report the discovery of a statistically significant hardening in the Fermi-LAT -ray spectrum of Centaurus A's core, with the spectral index hardening from $Γ_{1}=2.73 \pm 0.0…
Signatures of clumpy dark matter in the global 21 cm background signal
D. T. Cumberbatch, M. Lattanzi, J. Silk
We examine the extent to which the self-annihilation of supersymmetric neutralino dark matter, as well as light dark matter, influences the rate of heating, ionisation and Lyman-al…
Observational Constraints on Open Inflation Models
Martin White, Joe Silk
We discuss observational constraints on models of open inflation. Current data from large-scale structure and the cosmic microwave background prefer models with blue spectra and/or…
Cold Dark Matter Resuscitated?
Martin White, Douglas Scott, Joe Silk +1
The Cold Dark Matter (CDM) model has an elegant simplicitly which makes it very predictive, but when its parameters are fixed at their `canonical' values its predictions are in con…
Can a mass inversion save solar neutrino oscillations from the Los Alamos neutrino?
G. Raffelt, J. ~Silk
In the light of the neutrino oscillations which may have been observed at the LSND experiment we explore the consequences of two inverted mass schemes where solar neutr…
Structure Formation with Decaying Neutrinos
M. White, G. Gelmini, J. Silk
We consider the effects of a massive, unstable neutrino on the evolution of large--scale structure and anisotropies in the cosmic microwave background. Comparison with large--scale…
Baryonic Dark Matter and the Diffuse Gamma Ray Background
Xiaochun Luo, J. Silk
We show that the baryonic gas content of the halo of our galaxy can be probed by performing a multipole expansion on the distribution of diffuse background gamma-ray emission. Whil…
Point Sources in the Cosmic Microwave Background?
Xiaochun Luo, J. Silk
Non-Gaussian imprints on the cosmic microwave background radiation (CBR) sky are within the grasp of current experiments. A clear non-Gaussian signature would be point-like sources…
The Imprint of on the Cosmic Microwave Background
Naoshi Sugiyama, Joseph Silk
We investigate the dependence of large angular scale cosmic microwave background anisotropies on various initial conditions, including both adiabatic and isocurvature perturbations…
Reionization and cosmic microwave background distortions: a complete treatment of second order Compton scattering
Wayne Hu, Douglas Scott, Joseph Silk
The ionization history of the universe provides a major source of ambiguity in constraining cosmological models using small angular scale microwave background anisotropies. To clar…
