Abstract. The working group on astroparticle and neutrino physics at

WHEPP-9 covered a wide range of topics. The main topics were neutrino

physics at INO, neutrino astronomy and recent constraints on dark

energy coming from cosmological observations of large scale structure

and CMB anisotropy.

Keywords. Matter effects; neutrino oscillations;

neutrino mass models; cosmology; cosmic microwave background;

dark energy; large-scale structures.
