DESCRIPTION:Speakers: Pier Stefano Corasaniti (LUX\, Observatoire de Paris
 )\n\nDark matter halos are the fundamental building blocks of cosmic struc
 ture formation. They provide the gravitational wells into which baryonic g
 as collapses\, giving rise to the stars and galaxies observed today. The i
 nternal mass distribution of halos reflects both their hierarchical assemb
 ly history and the complex baryonic processes that shape their evolution. 
 As a result\, halo mass profiles encode valuable cosmological and astrophy
 sical information. Traditionally\, cosmological constraints from halo stru
 cture have relied on parametric descriptions of the mass profile\, such as
  the Navarro–Frenk–White model. In this talk\, I will present a comple
 mentary non-parametric statistical approach\, known as halo sparsity\, and
  discuss its application to observations of galaxy clusters.\n\nhttps://in
