Francisco "Paco" Prada

I'm research staff at the Extragalactic Astronomy department of the Instituto
de Astrofisica de Andalucia (Granada, Spain) of the CSIC, Spanish National Research Council. I'm leading a group in Granada working on various theoretical and observational aspects of Cosmology and Astro Particle Physics. I'm also involved in several instrumentation projets.

  • January 2010: Testing the IAA-AVS Fiber Positioner for GTC

    • SIDE is an intermediate resolution fibre fed spectrograph dedicated to wide field MOS and 3D spectroscopy. It will operate in the visible and near-IR spectral domain. First performance tests of our Fiber Positioner are being done at the IAA (M. Azzaro, S. Becerril ...) and AVS Labs ...

  • June 2009: Upper Limits on the VHE Gamma-Ray Emission from the Willman 1 Satellite Galaxy with the Magic Telescope by the MAGIC Collaboration (including M. A. Sanchez-Conde, Fabio Zandanel, & Francisco Prada)

    • We present the result of the observation of the ultrafaint dwarf galaxy Willman 1 performed with the 17 m MAGIC telescope during 15.5 hr between March and May 2008. No significant gamma-ray emission was found. We derived upper limits of the order of 10-12 ph cm-2 s-1 on the integral flux above 100 GeV, which we compare with predictions from several of the established neutralino benchmark models in the mSUGRA parameter space. Flux boost factors of three orders of magnitude are required even in the most optimistic scenario to match our upper limits. However, uncertainties in the dark matter intrinsic and extrinsic properties may significantly reduce this gap ...

  • January 2009: Testing Gravity With Motion of Satellites Around Galaxies: Newtonian Gravity Against Modified Newtonian Dynamics by Klypin & Prada

    • The motion of satellite galaxies around normal galaxies at distances 50-500 kpc provides a sensitive test for theories. We show that observational data strongly favor the standard model; all three major statistics of satellites - the number-density profile, the line-of-sight velocity dispersion, and the distribution function of the velocities - agree remarkably well with the predictions of the standard cosmological model. Thus, the success of the standard model extends to scales (50-500) kpc, much lower than what was previously considered. Modified Newtonian dynamics (MOND) fails on these scales ...
