SUMMARY:Cosmology with cosmic voids\, Theory Seminar (High Energy/Cosm
 ology)\, Alice Pisani\, Princeton
DESCRIPTION:Modern surveys provide access to high quality measurements
  on large areas in the sky and span large redshift ranges—thus sampl
 ing the galaxy distribution in detail also in the emptier regions\, vo
 ids. Void cosmology is becoming an increasingly active sector of galax
 y clustering analysis: by measuring void properties\, such as the void
  size function or density profiles\, it is possible to constrain cosmo
 logical parameters. Voids are particularly sensitive to the properties
  of dark energy and are a powerful tool to test modifications of the l
 aws of General Relativity. In this talk I illustrate the use of cosmic
  voids as a tool for cosmology\, I present recent developments in the 
 field and discuss the constraining power of voids to be observed by up
 coming surveys.
