Data reduction pipeline for emir, the near-IR multi-object spectrograph for GTC

EMIR (Balcells et al. 2000) is a near-infrared wide-field camera and multi-object spectrograph being built for the GTC. The Data Reduction Pipeline (DRP) will be optimized for handling and reducing near-infrared data acquired with EMIR.

Emission-line galaxy surveys with GTC: The Hα Universe

Emission line galaxies are the most easily detected and studied objects in the high redshift Universe. They are being used to trace the evolution of critical observables of the Universe such as Star Formation Rate densities, starburst properties and abundances. Most of the research is being done using [OII]3727 and UV lines, but Hα is still one the best tracers for Star Formation Rate and physical properties of current star-forming galaxies. As a complementary contribution to studies of galaxy evolution, our team has focused into a long-term project to study the population of Hα-selected star-forming galaxies of the Universe at different redshifts. In 1995 we first determined the local Hα luminosity function, and from it the Star Formation Rate density (SFRd) of the local Universe. We then, using narrow-band imaging in the optical, extended this measurement to z ≃ 0.24 and z ≃ 0.4. Working in the near-infrared, GTC will be a very powerful tool to study the evolution of the Hα emission-line galaxy populations at different redshifts. We will both quantify the SFRd evolution and characterize the star-forming galaxy populations by directly comparing the same observables at all redshifts up to z ≃ 2.5.

Ammonia observations of the nearby molecular cloud MBM 12

We present NH_3(1,1) and (2,2) observations of MBM 12, the closest known molecular cloud (65-pc distance), aimed at finding evidence for on-going star formation processes, No local temperature (with a T_rot upper limit of 12 K) or linewidth enhancement is found, which suggests that the area of the cloud that we have mapped (∼ 15-arcmin size) is not currently forming stars. Therefore this nearby 'starless' molecular gas region is an ideal laboratory to study the physical conditions preceding new star formation. A radio continuum source has been found in Very Large Array archive data, close to but outside the NH_3 emission. This source is likely to be a background object.

Una mirada a la dispersión de semillas en las excretas de mamíferos

Terrestrial mammals are good dispersers of the fruits and seeds of seasonal rainforest in the Gulf of Mexico. Their importance lies in the huge quantity of fruit and seeds they consume, and their daily and seasonal movement through natural and secondary vegetation and agricultural fields. Their importance is even more noteworthy in the face of increasing deforestation and forest fragmentation, which limits the dispersal of propagules across the landscape and affects, among other things, the potential for forest regeneration. To evaluate fruit and seed consumption and dispersal over 12 months, the droppings of rainforest mammals were analyzed for the rainforest and an abandoned pasture (8,400 m2 respectively) on the coast of central Veracruz, Mexico. In the rainforest 158 droppings were collected and 47 in the pasture from a total of eight mammal species, six of which are known dispersers. The droppings contained 150 seeds belonging to 36 species and 19 families. The deposition of different species and quantities of seeds in the forest and pasture indicates that mammals disperse more rainforest species to the pasture than vice versa.

Sergio Bagu : Entre la historia y la sociología. Contribuciones al estudio de América Latina

A través de las obras escritas por Sergio Bagú (1911-2002) referidas a los problemas sociológicos e históricos de América Latina se busca explorar la contribución científica e investigativa que este argentino construyó para pensar la unidad de nuestros pueblos, siguiendo la tradición intelectual de personajes como Alfonso Reyes, José Luis Romero, Justo Sierra, Pedro Henríquez Ureña, Rafael Gutiérrez Girardot, entre otros. La ponencia explora los contenidos metodológicos e investigativos de las principales obras sociológicas e históricas de Sergio Bagú y abre el debate hacia la pregunta de si es posible una ciencia propiamente latinoamericana en esos campos y cómo esos saberes enfrentan los profundos dilemas latinoamericanos en el siglo XX y XXI

Mockumentary as postnationalism: national identity in 'A Day Without a Mexican' by Sergio Arau

The turn to neoliberalism in the 1990s proved decisive for Mexico, as the NAFTA project embraced by the Salinas administration entailed a re-definition of national identity, defined since the revolution as mestizo, Catholic and especially as the Other to the United States. And just as cinema was in those days a crucial discourse for this particular construction of the identity, it was in the 1990s equally instrumental to its redefinition, which largely focused on the role of migrants to the US, presented even as supplementary in the Derridean sense. In 1992, as part of these efforts, Sergio Arau directed a mockumentary which in 2004 became a feature film, ‘A Day Without a Mexican’. As would befit more the seriousness of a documentary than the excess and parody of mockumentary, the stated aim in both was to advance a social agenda, arguing the case for immigrant labour and for Mexican presence in the US more generally. The film charts what would happen in California were all Latino immigrants to suddenly disappear, arguing chaos would ensue. Given the link between cinema and modernity and the relevance of cinema for the nation as an alternative public sphere, this chapter looks at the implications of choosing mockumentary, taken by many to be a paradigmatic postmodern and hybrid form, to discuss the hybridisation of national identity in a transnational film, in the present age of globalisation.
