Abstract: We present a measurement of the Lyman-$alpha$ (Ly$alpha$) intensity mapping power spectrum from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). We measure the cross-power spectrum of the Ly$alpha$ intensity and Ly$alpha$-emitting galaxies (LAEs) in a redshift range of $1.9 arXiv:2510.11427v1 Announce Type: new
