  • Correlations in superstatistical systems

    We review some of the statistical properties of higher-dimensional superstatistical stochastic models. As an example, we analyse the stochastic properties of a superstatistical model of 3-dimensional Lagrangian turbulence, and compare with experimental data. Excellent agreement is obtained for various measured quantities, such as acceleration

  • Cosmic Microwave Background Observations from Tenerife

    This contribution reports the status of the Cosmic Microwave Background (CMB) experiments on Tenerife. These include the classic Tenerife beam-switching experiments at 10, 15 and 33 GHz, the Jodrell-IAC interferometer at 33 GHz, the COSMOSOMAS project and the Cambridge-IAC Very Small Array (VSA).

  • 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 both the global liquid water cloud fraction (LCF) and other closely correlated atmospheric parameters. To test the validity of these findings we have concentrated on just one property, the

  • COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses. IX. Time delays, lens dynamics and baryonic fraction in HE 0435-1223

    We present accurate time delays for the quadruply imaged quasar HE 0435-1223. The delays were measured from 575 independent photometric points obtained in the R-band between January 2004 and March 2010. With seven years of data, we clearly show that quasar image A is affected by strong microlensing variations and that the time delays are best

  • Cosmological implications of baryon acoustic oscillation measurements

    We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave background (CMB) data and a recent reanalysis of Type Ia supernova (SN) data. In particular, we take advantage of high-precision BAO measurements from galaxy clustering and the
