Just after inflation, due to the coupling between photons and baryons, sound waves were created and propagated in the primordial plasma until recombination. At that time, these so called Baryonic Acoustic Oscillations (BAO) left their imprint in the matter distribution. This feature is still measurable as a small excess (1%) in the matter 2-point correlation function.
This BAO peak can be...

The VERITAS observatory is a ground-based air Cherenkov telescope array that detects very-high-energy gamma-ray emission (VHE;>100 GeV) from a range of astrophysical sources including nearly 40 Active Galactic Nuclei (AGN). The vast majority of these AGN are blazars where relativistic plasma jets aligned within a few degrees to our line of sight cause the observed radiation to be highly...
The BICEP/Keck series of experiments are small aperture
refracting telescopes designed to measure the polarization pattern
of the Cosmic Microwave Background at degree angular scales.
The latest BK15 results use measurements at 95, 150 and 220GHz,
in conjunction with additional bands from WMAP and Planck,
to constrain the foreground signal and set the limit r<0.07
(95% confidence). I will...
