Se atribuye a Sir Francis Bacon la célebre frase que dice: “Algunos libros son probados, otros devorados, poquísimos masticados y digeridos”. Pónganla en su buscador de webs y verán que les remite, al menos, a una decena de miles de páginas.

NIRSpec is the flagship spectrograph for JWST in the 0.6 to 5.3 micron wavelength range. Observation with the Micro- Shutter Assembly (MSA) for multiobject spectroscopy (MOS) will use configurable shutters to form spectral slits and provide the first

The cosmological origin of carbon, the fourth most abundant element in the Universe, is not well known and matter of heavy debate. We investigate the behavior of C/O to O/H in order to constrain the production mechanism of carbon. We measured emissio

Between 1821 and 1886, the constitutional texts of the Republic of Colombia dealt with defining the bases of its electoral system and, consequently, of the model of political representation that should be imposed. To deal with mainly the requirements

The Near-Infrared Spectrograph (NIRSpec) is the work-horse spectrograph at 1-5microns for the James Webb Space Telescope (JWST). A showcase observing mode of NIRSpec is the multi-object spectroscopy with the Micro-Shutter Arrays (MSAs), which consist

We measure C III] 1907,1909 A emission lines in eleven gravitationally--lensed star-forming galaxies at z~1.6--3, finding much lower equivalent widths than previously reported for fainter lensed galaxies (Stark et al. 2014). While it is not yet clear

We have compiled a library of stellar Lyman-alpha equivalent widths in O and B stars using the model atmosphere codes CMFGEN and TLUSTY, respectively. The equivalent widths range from about 0 to 30 \AA in absorption for early-O to mid-B stars. The pu

Using a sample of 28 HII regions from the literature with measured temperature inhomogeneity parameter, t^2, we present a statistical correction to the chemical abundances determined with the Te(4363/5007) method. We used the t^2 values to correct th

We present long slit spectrophotometry of two HII regions: TOL2146-391 and TOL0357-3915. We performed a detailed analysis that involves abundance determinations relaxing the assumption of homogeneous temperature. The temperature inhomogeneities value

Emprender el estudio de la élite política de Huelva y su comportamiento durante el período electoral de 1923 presenta para nosotros un doble interés. Por un lado, y en la medida en que la historia contemporánea onubense sigue siendo una gran des
