The question of how a starburst is fuelled is closely related to some of the main outstanding problems in our understanding of starbursts, namely which combination of physical conditions leads to the triggering of the burst, and how long the burst can last. There is observational evidence that galactic bars and galaxy-galaxy interactions can lead

Phase diversity techniques are robust post-processing tools for image enhancement and correction of telescopic and atmospheric induced aberrations. We present results obtained applying the Partitioned Phase-Diverse Speckle (PPDS) technique to images acquired at THEMIS. We also present an image quality estimator based on image power spectrum content

Esta tesis está dedicada al estudio de la emisión galáctica difusa y las anisotropías de la radiación cósmica de microondas por medio de las observaciones del experimento COSMOSOMAS. También se analizan estas emisiones en los mapas de WMAP, publicados tras el primer año de operación del satélite. Se presentan los mapas de COSMOSOMAS a 12.7, 14.7 y

The recent detection of multiple harmonic standing transverse oscillations in coronal loops by Verwichte et al. is of special importance, as it allows one to obtain information on the longitudinal density variation in loops. Verwichte et al. detected the simultaneous presence of both the fundamental and the first-overtone mode in two coronal loops

We present direct evidence for anomalous microwave emission in the Perseus molecular cloud, which shows a clear rising spectrum from 11 to 17 GHz in the data from the COSMOSOMAS experiment. By extending the frequency coverage using W ilkinson Microwave Anisotropy Probe maps convolved with the COSMOSOMAS scanning pattern, we reveal a peak flux

As part of ELAIS, ISOCAM observations were carried out covering 10.3deg2 at 15um. The observations were carried out in raster mode, with most of the survey area confined to three northern fields (N1, 2.67deg2; N2, 2.67deg2; N3, 0.88deg2) (2 data files).
