    our group is working on the design of the software to detect and qualify the events pulses generated by the X ray photons in the detector and to perform the instrument characterization ARCHES Astronomical Resource Cross matching for High Energy Studies This project fits within the activities of our group combining our involvement in the XMM Newton observatory and its source catalogues with our interest on multi wavelength astronomy mainly on the properties of Active Galactic Nuclei We will collaborate in the development of a sophisticated tool to identify the same astronomical source across several catalogues at different wavelengths building automatically their Spectral Energy Distributions to be used at a later stage to study their physical nature In particular we will lead the exploratory scientific exploitation about Active Galactic Nuclei within this project Quasars with star formation Among our activities to understand better the interaction between the growth of supermassive black holes and the growth of their host galaxies we are carrying out a study of a sample of X ray luminous broad line quasars hence still feeding their central supermassive black hole copiously and also luminous in the far infrared indicative of active star formation and a growing host galaxy In addition these objects also show hints of over densities of sub millimetre galaxies also forming stars massively in their environments which would place these quasars in the centres of growing structures in the primitive Universe In collaboration with colleagues at MSSL University College London UK and at the Centre for Astrophysics Research University of Hertfordshire UK we are observing and analysing these objects across the wide electromagnetic spectrum from X rays to radio to understand their nature and place them in the fiercely debated landscape of co evolution of galaxies and their active nuclei The Bright Ultra hard XMM Newton Survey BUXS Obscured black hole growth in the z 1 Universe BUXS is a large scale AGN survey project in collaboration with colleagues at the University of Leicester UK and the Osservatorio Astronomico di Brera Italy that will determine the X ray luminosity function of luminous type 1 and type 2 AGN and its cosmological evolution in the z 1 Universe BUXS is one of the largest among the existing XMM Newton and Chandra surveys flux limited sample of X ray bright sources selected at ultra hard X ray energies 4 5 10 keV The survey consists of 258 AGN detected over a total sky area of more than 44 deg2 of which 98 are currently identified through an extensive program of optical spectroscopic follow up So far BUXS has been used to define a highly reliable and efficient infrared selection technique of AGN based on data from the Wide field Infrared Survey Explorer and it is currently been used to determine the emission properties of the circumnuclear dust in luminous AGN A mid infrared survey of AGN using CanariCam on the GTC We are carrying out a mid IR survey of local AGN using the CanariCam instrument

    aspects related to the analysis of the large scale structure LSS of the Universe One the one hand we have performed N body simulations of large volumes 300 Mpc h with and without gas particles in order to estimate the Rees Sciama effect The derivative of the potential is computed in these boxes and then projected along the line of sight with the observer at the centre of the box at redshift 0 These simulations can be used in studies looking at techniques to detect the ISW and or Rees Sciama effects We have also computed the gravitational lensing effect We also work on simulations of the high redshift Universe with a focus on the reionization period and the opportunities to study this epoch with future instruments In addition to the simulation work we also investigated on optimal cross correlation tools to extract the common signal that is present on the CMB maps and on the LSS surveys due to the gravitational potential evolution In particular we were piooners by introducing wavelets in this field The scientific outcomes produced by these analyses is twofold First it probes the common physical origin between the CMB photons emitted at redshift 30000 and the matter distribution up to redshift around 2 Second it helps to put constraints to the cosmological parameters that define the Dark Energy properties SIGNAL PROCESSING AND STATISTICS A common task that is of crucial importance to all the previous research projects is the statistical analysis of the different astrophysical signals in order to obtain useful information about physical phenomena Statistical signal processing is the branch of mathematics that treats signals as stochastic processes dealing with their statistical properties as a means to derive rules from phenomena that apparently evolve in time in an unpredictable manner Examples of typical statistical signal processing tasks that have already been mentioned here are image processing model selection component separation and source detection In this era of technologically ambitious experiments we need to process huge loads of data in a fast and robust way Besides astrophysical data is usually very complex multiwavelenght observations polarization data non stationary and non Gaussian physical processes complicated systematics of the instrument etc For this reason it is important to develop appropriate data processing techniques and to implement them in the supercomputing facilities we have access to in the IFCA Some of the hot topics we are working with are Bayesian inference time frequency analysis linear and non linear filtering image fusion wavelets sparse representations Markov random fields non linear sampling denoising and inverse problems Our main goal is to use existing signal processing techniques and to develop new ones to be applied to the study of the Cosmic Microwave Background and the sub mm Universe but we are not restricted to thas field Many of the applications we are working with can be useful in other knowledge areas such as telecommunications geophysics bioinformatics and biomedical applications INSTRUMENTATION FOR MICROWAVE EXPERIMENTS Our research on instrumentation for microwave experiments follows
