1.5Jy MOJAVE AGN sample and 3FGL data

2016

We use the complete MOJAVE 1.5Jy sample of active galactic nuclei (AGNs) to examine the gamma-ray detection statistics of the brightest radio-loud blazars in the northern sky. We find that 23% of these AGNs were not detected above 0.1GeV by the Fermi-LAT during the four-year 3FGL catalog period partly because of an instrumental selection effect and partly due to their lower Doppler boosting factors. Blazars with synchrotron peaks in their spectral energy distributions located below 10^13.4^Hz also tend to have high-energy peaks that lie below the 0.1GeV threshold of the LAT, and are thus less likely to be detected by Fermi. The non-detected AGNs in the 1.5Jy sample also have significantly l…

Proyecto: cámara de conservación de libros para la Biblioteca Histórica de la Universitat de València

2017

Las dificultades para conseguir unas condiciones ambientales óptimas para la conservación de nuestro patrimonio bibliográfico y el elevado consumo energético necesario para mantenerlas han sido algunas de las premisas que nos han llevado a la proyección y realización de esta cámara de conservación. En ella se ha creado un espacio libre de influencia exterior que facilita la obtención de un clima adecuado y estable, con un consumo mínimo de energía, en el que se controlan los principales factores de degradación ambiental: temperatura y humedad precisas y estables, así como un control minucioso de la contaminación atmosférica y biológica; todo ello dirigido a aumentar la esperanza de vida de …

The impact of Open Access: benefits for individuals, organisations, and research progress

2017

In his presentation Mikael Laakso examines OA-related questions such as:What is the concept of OA benefits? What OA is most beneficial? What are some signs that OA is not fully leveraged currently? Presentation describes Open Access benefits for Individuals, Organisations, Universities, Libraries and Public & private sector.The overarching theme for the presentation is how OA is beneficial to research progress.
