ADAMIS


The ADAMIS team is a transverse cross-disciplinary team of the laboratory APC at the interface between (astro)physics, mathematics, statistical information processing, and scientific computing. It aims at developing, and applying to frontier physical problems, innovative techniques in data analysis, physical modeling, and numerical simulation. Fields of application are in the range of activites of the APC laboratory, namely astroparticle physics and cosmology.

 

The ADAMIS team gather specialists in astrophysical numerical simulations and experts in data processing and analysis. These two activities connect in a complementary way to observational data obtained by the various instruments dedicated to the observation of the Universe. While data analysis brings new information about the observed phenomena, numerical simulations enable us to test theoretical models involving the primary ingredients of the observed sources.

 

The ADAMIS team contributes to data analysis and simulation in aera such as cosmology (measurement of the cosmic microwave background, Sunyaev Zel'dovich effect, modelling of submillimeter sky emission), gravitation (through the detection of gravitational waves) and high-energy astrophysics (through the simulation of accretion discs, jets around compact objects, and the statistical distribution of high energy cosmic rays).

Jean-François Cardoso:

 

Fabien Casse:

I am associate professor (MCF) at the University Paris Diderot involved in modelling of certain high energy astrophysical phenomena, such as  an accretion and ejection of matter around compact objects (black holes, X-ray binaries, etc) and young stars, as well as of particle acceleration in astrophysical shocks. My research involves both theoretical and numerical aspects. In the latter case I use numerical, parallel (MPI) codes, which implement different mathematical equations, e..g, magnetohydrodynamic, kinetic, Fokker-Planck, as required by physical contexts. I am also a member of the collaboration SVOM-Eclairs - a future satellite dedicated to long-wavelength studies of the emission of gamma-ray bursts.

Eric Chassande-Mottin:

My research is devoted to devising, implementing, and applying data analyses methods and techniques relevant for data sets collected by gravitational wave experiments. I am involved in the Virgo collaboration and I am interested in particular  in transient sources. I also participate in a developmemt of multi-messenger approaches, which combine the observations of the gravitational waves with other observational probes, using either electromagnetic waves (for example via optical follow-ups) or neutrinos (in collaboration with ANTARES).

Jacques Delabrouille:

I am researcher at CNRS since 1999 and a member of the APC Laboratory, where from 2005 till 2010 I was responsible for first creating and then coordinating scientific activities of the research group ADAMIS. Since 1994 I have been working on a preparation of a satellite mission, Planck,  specializing predominantly on aspects of data analysis and their interpretations. I have been coordinating  the effort devoted to component separation and modelling of diverse sky emission (development of the Planck Sky Model) for High Frequency Instrument (HFI) of Planck.

I am interested particularly in the Cosmic Microwave Background (observations of Archeops, data analysis of the WMAP and Planck data sets), clusters of galaxies (observations of the instrument, Diabolo, 1998-2000, development of numerical software for modelling the Sunyaev-Zeldovich emission of the sky, studies of clusers using the WMAP data), and measurements of the CMB polarization  (studies of effects systematic, component separation, optimization of future CMB B-mode experiments).

Fabrice Dodu:

Since 2004 I am software engineer specialized in high performance computing and in particular I help to port numerical codes in some of national computing centers. In parallel I develop a new module for MHD-3D simulations of jets generated via the accretion-ejection instability.

 

Maude Le Jeune:

I am software engineer working at the APC Laboratory since 2005. I work on a software and data analysis development for the Cosmic Microwave Background data analysis. I am involved in the Planck satellite mission and ANR-project MIDAS'09.

Ed Porter:

 

Radek Stompor:

I am cosmologist and data analyst. My research interests revolve around anisotropies of the Cosmic Microwave Background radiation (CMB), their physics, and the role they play in improving our knowledge of the Universe. Recently, a main objective of my research has been the B-mode polarization of the CMB. In particular I work on the novel data analysis methods and their numerical  implementation in a form of high performance codes and algorithms suitable for the next generation of supercomputers (the project ANR-MIDAS'09). I am involved in some on-going and planned CMB experiments  such as a satellite mission, Planck, a balloon-borne experiment, EBEX and a ground based observatory, POLARBeaR.

Peggy Varniere:

My reseach is on the interface between numerical simulations (code development), analytic work, and a comparison with observations. I am interested in discs around compact objects and in particular in the explanation of their temporal variability. The other part of my work is concerned with protoplanetary discs either in the context of planet formations or interaction between the disc and the planet.

Josquin Errard:

I am a PhD student since September 2009 advised by Radek Stompor. My area of research is observational cosmology, in particular studies of the Cosmic Microwave Background radiation, which has been an exceptional source of constraints on new models of the Universe. I am a member of the POLARBeaR collaboration - a ground-based CMB B-mode experiment of the new generation.
In my doctoral work I am interested specifically in control of systematic effects on all levels from the instrument to the data analysis. My research project includes development of the new data analysis approaches, which are to be inclded in the data analysis pipeline of the POLARBeaR experiment.  I am also working with computer scientists and applied mathematicians in the context of the project ANR-MIDAS'09 aiming at developing inovvative tools for the analysis of the huge data volumes, which are to be produced by forthcoming generation of the CMB experiments.

Giulio Fabbian:

Je suis un étudiant italien de master 2 en stage de recherche pour six mois dans l'équipe ADAMIS sous la supervision de Radek Stompor.  Mes intérêts concernent la cosmologie observationelle et l'astronomie extragalactique, en particulier je m'intéresse aux problémes liés au Fond Diffus Cosmologique (CMB).
Mes expériences de recherche précédentes concernaient l'étude des sources radio extragalactiques non-résolues comme avant-plan pour les mesures du CMB aux basses fréquences. Maintenant je travaille sur la simulation numérique de l'effet de lentille gravitationnelle sur les anisotropies du CMB et sur son utilisation pour contraindre précisément la masse des neutrinos et l'équation d'état de l'énergie noire, la composante qui domine la densité d'énergie dans l'univers aujourd'hui.

Accès: 

Laboratoire APC is located in the Condorcet building of the campus Paris-Rive-Gauche. The building is composed of two parts, A and B, connected with overpasses. The offices of the ADAMIS group are on the 3rd floor in the part B of the Condorcet building, which is the one closer to the river Seine. The majority of the APC Lab, including the APC front desk, director's office, and most of the administrative offices, is in the part A of the building.

If you plan on paying a visit to the ADAMIS group, check first the APC website to learn how to reach the Paris-Rive-Gauche campus and the Condorcet building. Once you are there you can find the ADAMIS offices by entering the building B directly on the ground level as shown on the plan below.



Once in the building you should continue to the 3rd floor via the staircase or the elevator as both marked on the plan above.

If you are already in the building A, you can reach us by either going down to the ground level and following the instruction described above or you can use an overpass on the 4th floor to cross over from the building A to B and then take either a staircase or an elevator to get to the 3rd floor. This route is shown here:
