Description
In this talk, I will present our survey of enormous Lya nebulae at z=2. These enormous Lya nebulae reside in the density peak of large-scale structures. Using Keck Cosmic Web Imager, combined with the Subaru/HSC, ALMA and VLA, we studied the detailed properties and kinematics of the circumgalactic medium (CGM) through the emission. Combined with simulations, our observations are able to compare with detailed modeling and probe how galaxies are fed by the intergalactic medium and circumgalactic medium.
