We have obtained (in BVRI filters) the structural parameters of four disk galaxies, spanning a range of different morphological types. We believe the parameters are reliable because an extensive part of the galaxies' disks are free from contamination by other components, and a detailed photometric method has been used to derive these quantities

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

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).

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

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
