The dynamical flows of the intracluster medium (ICM) are largely unknown. We propose to map the spatial and kinematic distribution of the warm ICM of the nearby Virgo cluster using the Cosmic Origins Spectrograph. 15 sightlines at a range of impact parameters within the virial radius of the cluster (0.2 - 1.7 Mpc) will be probed for Lyman-alpha absorption and the data compared to blind HI, dust and x-ray surveys to create a multi-phase map of the cluster's ICM. Absorption line sightlines are commonly 40-100 kpc from a galaxy, allowing the flow of baryons between galaxies and the ICM to be assessed. The velocity distribution of the absorbers will be directly compared to simulations and used to constrain the turbulent motions of the ICM. This proposal will result in the first map of a cluster's warm ICM and provide important tests for our theoretical understanding of cluster formation and the treatment of gas cooling in cosmological simulations.

Our 22 orbit program will map the warm ICM of the Virgo cluster in Lya absorption using COS observations of background SDSS QSOs. We have chosen 15 UV bright QSOs from the SDSS DR5 QSO catalogue that lie at a range of impact parameters within the virial radius of the Virgo cluster. Our wavelength range (1150 -- 1450AA) will cover Lya absorption from the ICM gas, as well as other possible ions, including NV and SiIV. UV brightness has been assessed using Galex FUV and NUV magnitudes (m_FUV = 17.0 - 18.8; m_NUV = 16.9 - 18.0). We will employ the G130M (1300AA) grating with the FUV channel of COS to obtain 15km/s resolution spectra with good quality (S/N >= 10). The G130M grating has been chosen to enable us to separate the low-redshift Virgo absorption from the MW Lya trough and geocoronal emission. The combination of resolution and signal-to-noise is designed to allow us to detect weak absorption features, W > 50mA at 5sigma. Our observations will be sensitive to Lya absorbers beyond Milky Way velocities (~700km/s; set by the strength of the MW Lya absorption), out to the maximum velocity of the Virgo cluster (~3000km/s). All science observations are safe to conduct in TTAG mode. The acquisition strategy (mirror A vs B) has been chosen using the COS Imaging Acquisition ETC and the measured Galex NUV fluxes to normalise a variety of input spectra (both flat spectra, and QSO spectra redshifted to the measured QSO redshift). To be conservative, we chose the longest suggested exposure time among the various results, while ensuring count-rate limits are not exceeded. Science exposure times were estimated with the COS spectroscopy ETC, and extended to fully pack the orbits. BOT note: In 4 of our visits (Visits 8,9,10,12), the APT BOT designated 1 unsafe object in field of the PSA. In every case, this unsafe object is in reality our target. The count-rates estimated by the BOT are incorrect, since they assume a stellar spectral type of O5V for safety. All tests with the COS NUV Imaging Acquisition ETC indicate safe count rates (acceptable global count rate, <300cps for the 9x9 extracted box, and <50cps in the brightest pixel) as suggested in the Phase II instructions, and the ETC. In addition, for some of our visits the BOT notes some "unknown" sources. In all cases, these unknowns are either our science target, or they have no corresponding GALEX detection. Since all our targets are selected based on GALEX fluxes, these unknowns are within the GALEX coverage area (the GALEX FOV is 1.25deg in diameter), and the lack of UV detection implies they are not an instrument safety concern. Visit 5 note: Our science target for visit 5 has a star close to the target, ~5" to the SW. We have checked that this nearby object should not cause concern. The star is not seen in the galex survey, despite being in the galex FOV (GALEX tile AISCHV3_227_13249). GALEX has a PSF of ~5" FWHM, so if the star was UV bright, we would see this is a blended or non-symmetric target object. Inspection of the GALEX image shows no such assymetry. Further, the star is seen in the SDSS photometric survey (but no spectrum), and has g-r = 0.98; u - g = 2.33; the star is ~2.5mag fainter than our QSO target in u-band. Given the lack of UV flux, its red colour, and the lack of a BOT trigger, this star should not cause problems for either imaging acquisition, nor science exposures.
