    A Seismic Signature of a Second Dynamo?
    The Sun is a variable star whose magnetic activity varies most perceptibly on a timescale of approximately 11 years. However, significant variation is also observed on much shorter timescales. We observe a quasi-biennial (2 year) signal in the natural oscillation frequencies of the Sun. The oscillation frequencies are sensitive probes of the solar

    A search for debris disks in the Herschel-ATLAS
    Aims: We aim to demonstrate that the Herschel-ATLAS (H-ATLAS) is suitable for a blind and unbiased survey for debris disks by identifying candidate debris disks associated with main sequence stars in the initial science demonstration field of the survey. We show that H-ATLAS reveals a population of far-infrared/sub-mm sources that are associated

    A Detailed look at Chemical Abundances in Magellanic Cloud Planetary Nebulae. I. The Small Magellanic Cloud
    We present an analysis of elemental abundances of He, N, O, Ne, S, and Ar in Magellanic Cloud planetary nebulae (PNe) and focus initially on 14 PNe in the Small Magellanic Cloud (SMC). We derive the abundances from a combination of deep, high-dispersion optical spectra, as well as mid-infrared (IR) spectra from the Spitzer Space Telescope. A

    A complete X-ray and optical view on the absorption in BALQSOs
    We collect information for 88 broad absorption line quasars (BALQSOs) from the literature and existing catalogues, creating the largest BALQSOs sample analyzed optically and X-ray to date. We performed a full X-ray spectral analysis with different models on the sample of 39 sources with higher number of counts, and an approximate hardness-ratio

    A compact light-weighted and multi-purpose calibration unit for LINC-NIRVANA
    Laboratory and on-sky experience suggests that the integration of big astronomical instruments, specially of a complex interferometric system, is a challenging process. LINC-NIRVANA is the Fizeau interferometric imager for the Large Binocular Telescope (LBT). Simulating the final operating environment of every system component has shown how

  • Thesis
    "NUCLEOS DE GALAXIAS ACTIVAS A ESCALAS DE PARSECS"
    El centro de nuestra Vía Láctea, así como el de las galaxias más cercanas, constituye un excelente laboratorio para estudiar el entorno de agujeros negros supermasivos con una resolución espacial muy alta, del orden de unos pocos parsecs. Entender cómo funcionan estos objetos tan cercanos es el primer paso para identificar los mecanismos
