As part of a systematic search programme of a 10° wide strip of the northern Galactic plane, we present preliminary evidence for the discovery of four (and possibly five) new supernova remnants (SNRs). The pilot search area covered the 19-20 h right ascension zone sampling from +20° to +55° in declination using binned mosaic images from the Isaac

NEFER (Nuevo Espectrómetro Fabry-Pérot de Extrema Resolución) is a 3D instrument aimed to implement high resolution spectrometry for velocity determinations of extended stellar objects.

This communication presents a prototype image slicer for the 4-m European Solar Telescope (EST) designed for the spectrograph of the 1.5-m GREGOR solar telescope (GRIS). The design of this integral field unit has been called MuSICa (Multi-Slit Image slicer based on collimator-Camera). It is a telecentric system developed specifically for the

We present the first results of a study on the impact of the environment in the evolution of galaxies using a multiwavelength analysis of the young cluster RXJ1257.2+4738, from the optical to the far infrared, covering two virial radii. Our data set includes new observations of the GLACE survey --g', r', i', z' bands with OSIRIS/GTC and J band with

The unified model of active galactic nuclei (AGN) claims that the properties of AGN depend on the viewing angle of the observer with respect to a toroidal distribution of dust surrounding the nucleus. Both the mid-infrared (MIR) attenuation and continuum luminosity are therefore expected to be related to dust associated with the torus. We have

Magneto-acoustic and Alfvénic waves are ubiquitous in solar coronal loops, possibly being excited by photospheric motions. It is not clear, though, how these waves get so high, having obstacles such as the acoustic cut-off frequency, reflection and refraction of fast MHD waves and also the strongly reflecting transition region. In this contribution
