Grid Based Linear Neutrino Perturbations in Cosmological N-body Simulations
Jacob Brandbyge, Steen Hannestad
We present a novel, fast and precise method for including the effect of light neutrinos in cosmological N-body simulations. The effect of the neutrino component is included by usin…
Radio Signal by Galactic Dark Matter
Enrico Borriello, Alessandro Cuoco, Gennaro Miele
An interesting strategy for indirect detection of Dark Matter comes through the amounts of electrons and positrons usually emitted by DM pair annihilation. The e+e- gyrating in the…
The Barium Isotopic Abundance in the Metal-Poor Star HD140283
R. Collet, M. Asplund, P. E. Nissen
We derive the mixture of odd to even barium isotopes in the atmosphere of the metal-poor subgiant HD140283 from the analysis of the Ba II transition at 455.4 nm in a high-resolutio…
Solar-like oscillations in the G8 V star tau Ceti
T. C. Teixeira, H. Kjeldsen, T. R. Bedding +8
We used HARPS to measure oscillations in the low-mass star tau Cet. Although the data were compromised by instrumental noise, we have been able to extract the main features of the…
On the opacity change required to compensate for the revised solar composition
Jørgen Christensen-Dalsgaard, Maria Pia Di Mauro, Günter Houdek +1
Recent revisions of the determination of the solar composition have resulted in solar models in marked disagreement with helioseismic inferences. The effect of the composition chan…
Inflationary trispectrum from graviton exchange
David Seery, Martin S. Sloth, Filippo Vernizzi
We compute the connected four-point correlation function of the primordial curvature perturbation generated during inflation with standard kinetic terms, where the correlation is e…
