Detection of the first X-ray selected large AGN group
We have examined the spatial distribution of 856 AGN detected by the ROSAT
All-Sky Survey (RASS) using a direct search for structures with the minimal
spanning tree. The AGNs were compiled from an area of 7000 deg^2, in which
optical identifications of RASS sources were made with the help of the
digitized objective prism plates of the Hamburg Quasar Survey (HQS). Redshifts
were taken from the literature or from own follow-up observations. The sample
probes the spatial distribution at low redshifts, since the redshift
distribution peaks at z=0.1. The application of the minimal spanning tree led
to a 1.8 sigma discovery of an AGN group with 7 members in a volume V=140*75*75
h^-3Mpc^3 in the Pisces constellation. With a mean redshift z=0.27 this group
is only the third discovered group at redshifts z<0.5. The RASS offers
excellent possibilities to study large scale structure with AGNs at low
redshifts, once these redshifts are determined.Comment: 6 pages, 4 figures, accepted for publication in MNRA
El exclusivismo traductológico: ¿un mito völkisch?
Congreso Internacional celebrado en la Universidad Carlos III de Madrid del 24 al 26 de septiembre de 2012Martin Heidegger se hizo célebre por la voluntad de repetir la pregunta por el ser. Este trámite
está basado en el postulado de que el griego sólo es el logos. Es por eso que se esfuerza tercamente en regresar
a este idioma madre para resucitar la experiencia original y casi mĂstica de una identidad entre las palabras y
las cosas. Pero la idea subyacente es tambiĂ©n que el alemán serĂa el Ăşnico idioma moderno capaz de traducir el
griego antiguo respetando a su fuerza ontolĂłgica, o de reintegrar el significado del ser. No podemos dejar de
relacionar este “exclusivismo traductolĂłgico”, esta supremacĂa filosĂłfica del idioma germánico, con el proceso
entablado al pensamiento heideggeriano. En este artĂculo, me pregunto si este proceso es tĂpico del
pensamiento nazi, de la ideologĂa völkisch o si está relacionado con un nacionalismo mucho más antiguo
Literary practice according to Michel Henry
Although the author of four novels, Michel Henry never produced an aesthetics of literature. The purpose of this article is, after a presentation of his philosophy of immanence and his concept of life, to locate where the literary practice takes place in his system. In this study, we are not interested in the poetic quality of his works, but in the possibility to base his singular creativity on his philosophical reflection. This leads us to insert literature in the vast phenomenon of culture and ethics, and to grasp the function of poetics in the struggle against barbarism.Quoique l'auteur de quatre romans, dont l'un a été couronné par l'un des prix littéraires les plus prestigieux, Michel Henry n'a jamais véritablement formulé une esthétique du roman. L'objet de cet article est, après une étude détaillée de son concept de vie, de tenter de saisir quelle place la pratique littéraire pouvait avoir au sein de son système. Autrement dit, elle s'interroge sur la possibilité de fonder sa création littéraire sur sa réflexion philosophique
