<center>Astro_01 : *Towards a new era in ultra-high-energy cosmic-ray studies (UHECRs)* </center>

_Summary_ :<br>
Our collaborative research aims at preparing the operation of the next generation ultra-high-energy cosmic ray (UHECR) telescope, which will observe from space the fluorescence light of the UHECR-induced atmospheric showers. The collaboration involves hardware development and calibration, in the context of two pathfinder experiments (the EUSO-Balloon mission, led by France, and the EUSO-TA initiative, led by Japan), as well as theoretical work to understand UHECR origin and propagation across the universe.

<center>Astro_2 : *Cosmology with CMB Polarization Measurements* </center>

_Summary_:<br>
*Project goals are* :<br>
	i.	to devise optimized strategies for detection and characterization of the CMB B-mode polarization signals from the ground and satellite platforms<br>
	ii.	to contribute to the development of the satellite mission concepts: !CORE/PRISM and !LiTEBIRD<br>
	iii.	to contribute to the development of the ground based observational programs: POLARBEAR, POLARBEAR-2 and SIMONS ARRAY and later 
                the so-called STAGE-IV experiments<br>
	iv.	to analyse actual data sets as collected by the POLARBEAR experiments.
