Helion Mas du Bourboux ( University of Utah) – Baryonic Acoustic Oscillations in SDSS and DESI using the intergalactic medium absorption
April 13, 2018 @ 12:00 pm - 1:00 pm
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.
We 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.
INPA guests from campus can now come to the lab early on Fridays. The INPA Common Room (50-5026) is reserved for our guests from 10:00 a.m. to 12:00 noon and from 1 p.m. to 5 p.m. Note that the seminars are now held in 50A-5132 to accommodate a more significant number of attendees.
