The European Solar Telescope (EST) is a project of a new-generation solar telescope. It has a large aperture of 4 m, which is necessary for achieving high...
Recent Applications of Bayesian Methods to the Solar Corona
Solar coronal seismology is based on the remote diagnostics of physical conditions in the corona of the Sun by comparison between model predictions and...
We report some recent of the Tenerife experiments. On a strip at Dec = +40° we have identified structure in the microwave sky at several frequencies. Clear...
Recent SFR calibrations and the constant SFR approximation
Aims: Star formation rate (SFR) inferences are based on the so-called constant SFR approximation, where synthesis models are required to provide a calibration...
Recent Star Formation in Clusters of Galaxies: Extremely Compact Starbursts in A539 and A634
We report on the detection of two Hα-emitting extremely compact objects from deep images of the A634 and A539 clusters of galaxies at z~0.03. Follow-up long...
Recent Star Formation in Groups of Galaxies: HCG 31
Broadband UBVRI and narrowband H alpha and continuum images have been obtained for the Hickson compact group HCG 31 as part of an ongoing program devoted to the...
Reclassification of the nearest quasar pair candidate: SDSS J15244+3032-RXS J15244+3032
We present optical spectroscopy of the nearest quasar pair listed in the 13th edition of the Véron-Cetty & Véron catalogue, i.e. the two quasars SDSS J15244...
