Splinter Meeting eROSITA
eROSITA is Coming! Opportunities to Study Cosmology and Large Scale Structure with X-ray Selected Clusters and AGN
Time: Thursday September 21, 14:00-16:30
and 17:00-19:00
Room: HS4
Organizers: A. Finoguenov, A. Merloni, J. Mohr, T. Reiprich
The eROSITA instrument will launch as part of the Spectrum-Roentgen-Gamma
mission in late 2018 and will be employed to carry out eight all sky X-ray
surveys over a four year period. Each of these surveys will be equivalent to
four times the depth of the ROSAT All Sky Survey, the last X-ray sky survey that
was carried out in the early 1990's. The eROSITA dataset and the resulting
X-ray selected cluster and AGN catalogs will be released periodically during the
mission. Once redshifts are determined through joint analysis with multi-band
ground based datasets like those from the Dark Energy Survey, the eROSITA
cluster sample will enable precise studies of cosmology - including studies of
the underlying explanation for the accelerating expansion of the Universe -
through measurement of the cluster mass function and the spatial distribution of
the clusters and AGN. A key issue facing the eROSITA mission is the measurement
of the cluster mass scale using methods like weak lensing and dynamical masses.
In addition, the X-ray selected cluster and AGN populations will provide a rich
dataset for studies of the evolution of large scale structure and the galaxy
population out to redshift z~1 and beyond.
