Astroparticle and Cosmology Laboratory

This group, headed by Cyrille Rosset, includes two main areas of research:

1. Experimental investigation of the cosmic microwave background, including attempts to detect CMB polarization B-modes, which could provide support for the theory of Inflation. Researchers were involved in the Planck space mission{{cite web|url=http://prof.planck.fr/heading8.html |title=The Planck Satellite website |publisher=Prof.planck.fr |date=2009-04-03 |access-date=2014-01-14 |url-status=dead |archive-url=https://web.archive.org/web/20140115154210/http://prof.planck.fr/heading8.html |archive-date=15 January 2014 |df=dmy }} and are now active in the QUBIC experiment,{{cite web |url=http://www.qubic-experiment.org/ |title=[ QUBIC website ] |publisher=Prof.qubic.fr |date=2009-04-03 |access-date=2014-01-14 |archive-url=https://web.archive.org/web/20140116122235/http://www.qubic-experiment.org/ |archive-date=16 January 2014 |url-status=dead }} the Simons Observatory, and the LiteBIRD satellite.
2. Cosmological analysis of large spectroscopic and imaging surveys for the determination of constraints on the nature of dark energy. Researchers are involved in the wide-field observatories aimed at understanding the nature of dark energy: the large field Baryon Oscillation Spectroscopic Survey{{cite web|url=http://www.sdss3.org/collaboration/institutions.php |title=SDSS-III Institutions - SDSS-III |publisher=Sdss3.org |access-date=2014-01-14}} telescope, the Vera C.

Research carried out by this group, headed by Anne Lemière, aims at understanding the violent phenomena of the universe (mostly within compact stars, neutron stars, or black holes). The group is engaged in many international projects with telescopes or instruments detecting photons, cosmic rays, or neutrinos. For the observation of:

The group is involved in both ground-based (Virgo interferometer){{cite web|url=https://pub3.ego-gw.it/itf/Members_DB/Private/Institut_List.php |archive-url=https://archive.today/20140114142941/https://pub3.ego-gw.it/itf/Members_DB/Private/Institut_List.php |url-status=dead |archive-date=2014-01-14 |title=Virgo collaboration data base |publisher=Pub3.ego-gw.it |access-date=2014-01-14 }} and space-based (Laser Interferometer Space Antenna and its precursor LISA Pathfinder) instruments.{{cite web|url=http://www.lisa.aei-hannover.de/?page=pkollaboration&sub=lisapath&lang=en |title=LISA - LISA Pathfinder - Collaboration |publisher=Lisa.aei-hannover.de |access-date=2014-01-14}}

This group, headed by Dmitri Semikoz, covers the research topics of the laboratory from a theoretical perspective. It also carries out work on other areas of fundamental physics.

The staff of the laboratory consists of 75 permanent researchers and over 60 engineers, technicians, and administrative personnel, plus about 125 non-permanent employees (PhD students, postdoctoral fellows, visitors). In addition, the Paris Center for Cosmological Physics directed by George Smoot is also part of the laboratory{{cite web |url=http://pariscosmo.in2p3.fr/en |title=[ The PCCP website ] |access-date=2014-01-14 |archive-date=19 February 2014 |archive-url=https://web.archive.org/web/20140219020928/http://pariscosmo.in2p3.fr/en |url-status=dead }} and one of the three functional centres of the Astroparticle Physics European Consortium is based here.{{Cite web |url=http://193.146.122.114:8888/appec/about/functional-centers/apc.html |title=Appec - Apc |access-date=15 January 2014 |archive-url=https://web.archive.org/web/20160304032010/http://193.146.122.114:8888/appec/about/functional-centers/apc.html |archive-date=4 March 2016 |url-status=dead }}

An "International Associated Laboratory" in astroparticle physics was launched in September 2007. It associates the APC laboratory with the Kavli Institute for Particle Astrophysics and Cosmology (Stanford University).{{cite magazine|title=Astroparticle Physics Labs Join Forces |url=http://www2.cnrs.fr/en/1020.htm|magazine=CNRS International Magazine |date=October 2007 |issue=8}}

The laboratory has been evaluated twice by the AERES: in 2008{{cite report |year=2008 |title=Rapport du comité d'experts |url=http://www.aeres-evaluation.fr/content/download/11995/174662/file/AER_P07_006-2.pdf |language=fr |access-date=14 January 2014 |archive-url=https://web.archive.org/web/20140116132016/http://www.aeres-evaluation.fr/content/download/11995/174662/file/AER_P07_006-2.pdf |archive-date=16 January 2014 |url-status=dead }} and in 2013. In the latter evaluation, the lab won excellent scores (A or A+ in all criteria).

Astroparticle Physics European Consortium (APPEC) is a consortium of organizations from European countries that coordinate and fund research in astroparticle physics.{{cite web |title=About |url=https://www.appec.org/about |website=APPEC |access-date=21 September 2022}}
