SUMMARY:Helion Mas du Bourboux ( University of Utah) - Baryonic Acoustic Oscillations in SDSS and DESI using the intergalactic medium absorption
DESCRIPTION:We present the measurement of the Baryonic Acoustic Oscillation (BAO) scale from the correlation between absorption in the intergalactic medium and the positions of galaxies and quasars in the SDSS data and in the desi simulations. \nWe use the absorption by neutral Hydrogen and by Magnesium-II observed in quasar spectra to trace the underlying matter density fluctuations. Combined with galaxies and quasars\, these two tracers allow to measure the 3d cross-correlation of matter from a redshift of z = 0.5 up to a redshift of z = 2.4.
