Cosmic microwave background observations from the Cosmic Background Imager and Very Small Array: a comparison of coincident maps and parameter estimation methods
We present coincident observations of the cosmic microwave background (CMB) from the Very Small Array (VSA) and Cosmic Background Imager (CBI) telescopes. The...
Cosmic microwave background observations with the Jodrell Bank-IAC interferometer at 33GHz
This paper presents the first results obtained with the Jodrell Bank-IAC two-element 33-GHz interferometer. The instrument was designed to measure the level of...
Cosmic ray decreases and changes in the liquid water cloud fraction over the oceans
Svensmark et al. (2009) have recently claimed that strong galactic cosmic ray (GCR) decreases during ‘Forbush Decrease (FD) events’ are followed by decreases in...
Cosmic ray oriented performance studies for the JEM-EUSO first level trigger
JEM-EUSO is a space mission designed to investigate Ultra-High Energy Cosmic Rays and Neutrinos (E > 5 ṡ 1019 eV) from the International Space Station (ISS)...
Cosmic rays linked to rapid mid-latitude cloud changes
The effect of the Galactic Cosmic Ray (GCR) flux on Earth's climate is highly uncertain. Using a novel sampling approach based around observing periods of...

The effect of the Galactic Cosmic Ray (GCR) flux on Earth's climate is highly uncertain. Using a novel sampling approach based around observing periods of...
We examine the distribution of the [O/Fe] abundance ratio in stars across the Galactic disk using H-band spectra from the Apache Point Galactic Evolution...
Cosmic void baryon acoustic oscillation measurement: evaluation of sensitivity to selection effects
Cosmic voids defined as a subset of Delaunay triangulation (DT) circumspheres have been used to measure the baryon acoustic oscillations (BAO) scale; providing...
