The new tools developed are consolidating the online learning modality at the university level all over the world and in all disciplines.In this study, we present the case of the Master of Astronomy and Astrophysics which is running from 2010 in the Valencian International University (http://www.viu.es). Unlike other more consolidated distance universities in Spain, the teaching method which has opted in this case includes an element of presence via webcam. This method could be considered as a kind of blended learning, combining the advantages of traditional e-learning with the humanity of personal and direct contact with the students.The results of participation in the master beyond the initial expectations with 37 students enrolled, of which approximately 80% were Spanish and the other 20% were mostly from Latin American countries. The feedback provided by students in the first months of teaching appreciates favorably the presence component, while casting doubt on the usefulness of certain tools traditionally used in the field of e-learning.

Research paper thumbnail of Morphostatistical characterization of the spatial galaxy distribution through Gibbs point processes

The galaxy distribution is supposed to exhibit two components. The first one is related to the major geometrical features exhibited by the observed galaxy field, here, its corresponding filamentary pattern. The second one is related to the interactions exhibited by the galaxies. Gibbs point processes are statistical models able to integrate these two aspects in a probability density, controlled by some parameters. Several such models are fitted to real observational data via the ABC shadow algorithm. This algorithm provides simultaneous parameter estimation and posterior-based inference, hence allowing the derivation of the statistical significance of the obtained results.

Although this galaxy is often classified as a member of a loose group, all the neighbouring galaxies are much fainter and could be taken as satellites of NGC1600. The number density profile of galaxies in the field of this galaxy shows a decline with radius, with evidence of a background at approximately 1.3 Mpc. The density and number density profile are consistent with that found for other isolated early-type galaxies. NGC1600 appears as an extended source in X-rays, and the center of the X-ray emission seems not to coincide with the center of the galaxy. The velocity distribution of neighbouring galaxies has been measured from optical spectroscopic observations and shows that the mean radial velocity is approximately 85 km s −1 less than that of NGC1600, indicating that the centre of mass could lie outside the galaxy. The velocity dispersion of the ‘group ’ is estimated at 429 ± ...

Prior to the installation of the main camera (4.2 deg2 field-of-view with 1.2 Gpixels), the JST was equipped with the JPAS-Pathfinder, a one CCD camera with a 0.3 deg2 field-of-view and plate scale of 0.23 arcsec pixel−1. To demonstrate the scientific potential of J-PAS, the JPAS-Pathfinder camera was used to perform miniJPAS, a ∼1 deg2 survey of the AEGIS field (along the Extended Groth Strip). The field was observed with the 56 J-PAS filters, which include 54 narrow band (FWHM ∼ 145 Å) and two broader filters extending to the UV and the near-infrared, complemented by the u, g, r, i SDSS broad band filters. In this miniJPAS survey overview paper, we present the miniJPAS data set (images and catalogs), as we hi...
