HaloSat Observation of the Virgo Intracluster Medium.

HEWITT N.H., KAARET P. and FULLER C.A.

Abstract (from CDS):

Contained within a galaxy cluster, the Intracluster Medium is comprised of hot, X-ray emitting material between member galaxies. The nearest (∼16.1 Mpc) large galaxy cluster is Virgo. Virgo covers an approximately 12° diameter field, making it challenging to observe in its entirety. The HaloSat satellite utilized a 7° radius field of view to obtain the first full cluster observations since 1994. We then fit the cluster spectra with a plasma emission model of fixed metallicity. Our best fit temperature is kT = 1.39 ± 0.11 keV. We report a cluster luminosity of 5.8 ± 0.7 × 1043 erg s–1 and an emission measure of 5.8 ± 0.6 × 1066 cm–3.
