Introduction: 
We, scientist, exploit many numerical tools to compare our theoretical predictions with the universe we observe today with telescopes, balloons satellites.
Answer: 
<p>To predict the temperature fluctuations in the Cosmic Microwave Background (CMB), as well as the spatial distribution of galaxies, we use the numerical code <a href="http://camb.info" title="CAMB">CAMB</a>.</p> <p>Then, we take the measurements made by the different experiments, for instance, for the CMB, we use data from the <a href="http://lambda.gsfc.nasa.gov" title="NASA Lambda site">NASA Lambda site</a> and for the spatial distribution of galaxies, we use data from the different galaxy surveys, as, for instance, data from the <a href="http://www.sdss3.org" title="Sloan Digital Sky Survey III">Sloan Digital Sky Survey III</a> and perform a fit to our theoretical predictions using <a href="http://cosmologist.info/cosmomc/" title="Monte Carlos methods">Monte Carlos methods</a></p> <p>We also make theoretical predictions of the expected signatures from the different particles that will appear in the Large Hadron Collider (LHC)<a href="http://lhc.web.cern.ch/lhc/" title="Large Hadron Collider (LHC)">Large Hadron Collider (LHC)</a>, using generators of high energy events, as <a href="http://home.thep.lu.se/~torbjorn/Pythia.html" title="Pythia">Pythia</a> or <a href="http://herwig.hepforge.org" title="Herwig">Herwig</a>, and, together with the detector simulations, as those made by <a href="http://geant4.cern.ch" title="Geant4">Geant4</a> we do our physical analyses, using <a href="http://root.cern.ch/drupal/" title="ROOT">ROOT</a>.</p> <p>For the signals expected from dark matter annihilation products from the center of the galaxy, or the Sun&#39;s interior, we use other tools, as <a href="http://www.physto.se/~edsjo/darksusy/" title="DARKSUSY">DARKSUSY</a> and for neutrinos arising from dark matter annihilation products, we use <a href="http://copsosx03.physto.se/wimpsim/" title="WIMPSIM">WIMPSIM</a>.</p> <p>For neutrinos propagating from a man-made source towards a detector crossing the Earth interior we use <a href="http://www.mpi-hd.mpg.de/personalhomes/globes/" title="GLobES">GLobES</a> and then we fit the data to the different theoretical models using the <a href="http://www.theophys.kth.se/~mbl/montecubes/" title="MonteCUBES Package">MonteCUBES Package</a>.</p>

To predict the temperature fluctuations in the Cosmic Microwave Background (CMB), as well as the spatial distribution of galaxies, we use the numerical code CAMB.

CMB measurements from the South Pole Telescope

The most recent CMB measurements from the South Pole Telescope, combined with data from the CMB, BAO, H_0 and Sunzaey Zeldovich cluster abundances seem to indicate a cosmological preference for non-zero neutrino masses, being the mean value on the sum of the three neutrino masses

sum m? = 0.32 ± 0.11 eV

This measurement implies a quasi-degenerate neutrino mass spectrum, and it has crucial consequences for ongoing and future neutrinoless double beta decay searches.

Welcome

This is a very informal gathering of some seniors of the Invisibles team and also some young scientists presently in those teams, who will give brief presentations of their current physics research. The aim is to foster scientific collaboration and organization of the Invisibles project (www.invisibles.eu).
