Determining Galaxy Bias of the AEGIS Survey Field

Galaxy bias plays an integral role in using galaxies as tracers for large-scale structure. To determine this bias in the AEGIS survey field, the galaxy power spectrums from mock lognormal realizations of position and velocity data and real data are compared. This is accomplished by analyzing WFC3 grisms and creating masks that block out regions of the sky that are blemished by spectra of bright sources.
