Theory Seminar: Electronvolt sterile neutrinos: a critical appraisal

Friday, 29 April 2016 from 14:30 to 15:30 (Europe/Madrid) at IFAE ( IFAE Seminar room )

Speaker: Pedro A. N. Machado (IFT Madrid)

In this talk I review the situation of the short baseline neutrino oscillation anomalies that are still unexplained. The LSND, MiniBooNE, reactor and gallium anomalies will be described and discussed. A critical view of the anomalies in terms of neutrino oscillations will be given. The problem with cosmology will be considered, together with terrestrial oscillation and non-oscillation experiments that can help elucidate this puzzle.

Theory Seminar: Some new ideas on dark matter decay

Friday, 8 April 2016 from 12:00 to 13:00 (Europe/Madrid) at IFAE ( IFAE Seminar room )

Speaker:Òscar Catà (LMU Universitaat Munich)

I will explore two different scenarios to account for the long lifetime of dark matter. In the first one, I will assume that dark matter is stable when coupled to the SM but can proceed through (non-minimal) interactions to gravity. Based on current observations, I will show that even this ‘gravitational portal’ to dark matter decay is rather constrained. In the second scenario, I will present an extension of the SM where the dark matter candidate can be absolutely stable without the aid of ad hoc additional symmetries.

Theory Seminar: Disambiguating the Cosmological Dark Sector

Friday, 18 March 2016 from 12:00 to 13:00 (Europe/Madrid) at IFAE ( IFAE Seminar room )

Speaker: Iggy Sawicki (Geneva U)

Our observations of dark matter and dark energy are, at least so far, based purely on their effect on their combined effect on the geometry of the universe and therefore ambiguous in a fundamental way. As we progress toward building ever more precise maps of the universe, it will become increasingly important to understand what we can measure definitely, in a model-independent manner and what we can only say on the assumption of a model. I will discuss how to construct such model-independent observables, and the fundamental limits to our knowledge that can only be broken by employing parameterisations resulting from particular models. I will discuss how to approach parametrising our ignorance in a minimal yet consistent and physical manner and ask to what extent such modelling can actually account for anomalies we are beginning to see in cosmological data.

The PAU camera is now fully commissioned and ready to be offered as a visitor instrument




The PAU Camera saw first light in June 2015 and has successfully completed two observation periods in November 2015 and April 2016, starting its Science Survey programme. Over 5000 science exposures have been taken, covering about 1.5 deg2 of the sky using the full set of 40 narrow band filters and up to 5 deg2 with a subset of them.  This area is equivalent to about 500 deg2 area with single band and single exposures taken in 9 nights of good weather. The current PAU dataset has been reduced, calibrated and matched to deeper overlapping samples in about 1 day of real time. The result is about 75000 complete PAU low resolution spectra to iAB<23mag. The data reduction resulted in over 5 Terabytes and  71 million object measurements and was performed in record time using the PIC infrastructure and a preliminary PAUcam community pipeline. The figure shows an example comparison of some PAU calibrated spectra (taken in April 2016) with public galaxy and star SDSS spectra, with no adjustments.

The PAU Survey aims to cover 100 deg2 providing spectral information in fields where deep weak gravitational lensing data are available. This will result in new spectra for several million galaxies up to iAB<23 mag. Other science studies can be done with this camera which has the capability to determining SED for all objects in a large field of view.

PAUcam can also be used for Broad Band imaging with ugrizY on 18 4Kx2K red-sensitive fully depleted CCD's of 15 μm with a ~1 deg2 FoV (with vignetting outside the central 40 arcmin diameter).

The PAUcam system has also evolved to become more user friendly and able to be operated by other astronomers from the ING community. With the commissioning of the Autoguider at the beginning of April 2016 the camera is now fully commissioned.

Detailed information on the camera performance and how to prepare for observation periods with PAUCam can be found at

España y Japón acuerdan la instalación de cuatro nuevos telescopios en la isla de La Palma

  • Los instrumentos formarán parte de la futura Red de Telescopios Cherenkov – Hemisferio Norte (CTA-Norte) en el Observatorio del Roque de los Muchachos.

La secretaria de Estado de I+D+i, Carmen Vela, ha presidido junto al viceministro de Educación, Cultura, Deporte, Ciencia y Tecnología japonés, Tsutomu Tomioka, la firma del acuerdo de colaboración para la instalación y operación de cuatro telescopios Cherenkov en el Observatorio del Roque de los Muchachos, en la isla de La Palma. El acuerdo ha sido firmado en Tokio por Rafael Rebolo, director del Instituto de Astrofísica de Canarias (IAC), y Takaaki Kajita, director del Instituto de Investigación de Rayos Cósmicos de la Universidad de Tokio (ICRR, por sus siglas en inglés). Ha contado también con la presencia de dos miembros del IFAE: Manel Martínez, coordinador de CTA España, y Juan Cortina, coinvestigador principal del LST.

Los cuatro telescopios Cherenkov, de 23 metros de diámetro, denominados Large Size Telescopes (LST, por sus siglas en inglés), permitirán la observación de rayos gamma de alta energía y fenómenos asociados con la materia oscura. Estos telescopios serán los más grandes del Observatorio CTA-Norte que España acogerá en La Palma y juntos formarán la parte central de la infraestructura, alrededor de los cuales se instalarán otros 15 de 12 metros de diámetro, denominados MST.

Los telescopios LST están diseñados por investigadores y tecnólogos de universidades y centros de investigación internacionales (Japón, Italia, Francia, Alemania, Brasil, India, Suecia y Croacia) en colaboración con grupos de investigación españoles de la Universidad de Barcelona, del Instituto de Física de Altas Energías (IFAE), del Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (CIEMAT), de la Universidad Complutense de Madrid, de la Universidad Autónoma de Barcelona, del Instituto de Ciencias del Espacio de la Universidad Autónoma de Barcelona, de la Universidad de Jaén y del IAC.

Esta nueva infraestructura científica internacional multiplicará por diez la capacidad de los instrumentos actuales, lo que permitirá abordar una nueva visión del Universo, más allá de la óptica, aportando datos impredecibles y actualmente desconocidos sobre energías cósmicas, agujeros negros y supernovas. En virtud del acuerdo, el IAC instalará y participará en el desarrollo y operación de los cuatro telescopios y garantizará el derecho a uso de las instalaciones por parte de la comunidad científica, renovando su validez automáticamente durante cada año tras un periodo inicial de diez.

Abril 2016: Plaza de Ingeniero Informático Técnico/Superior
