We have also cleaned up the description of observations. 1584463710 ----- Attempting Submission 1 (Thu Jul 24 06:24:52 GMT 2014) ----- ----- Attempting Submission 2 (Fri Aug 01 00:59:35 GMT 2014) ----- Mapping the Broad-band Spectrum of a New Candidate Intermediate Mass Black Hole We request joint XMM-Newton & HST observations of a new intermediate mass black hole candidate in the galaxy LEDA 87326 to map the broad-band spectral energy distribution from X-ray to near-IR. Previous observations with the XMM-Newton EPIC and OM cameras detected an X-ray source with an observed 0.2-10 keV luminosity of 6E41 erg/s, with the X-ray spectrum dominated by a hard power law and the UV/optical data consistent with thermal emission from a cool (~0.08 keV) accretion disc. The high X-ray luminosity and low disc temperature imply a black hole mass > 4000 Msun. By observing this source simultaneously with XMM-Newton and the HST we will confirm that the observed optical emission is from an accretion disc and determine whether any reprocessing in the outer disc is present. We will observe a new intermediate mass black hole candidate in the galaxy LEDA 87326 simultaneously with XMM-Newton and HST to map the broad-band spectral energy distribution from X-ray to near-IR. We will image the target with HST imaging observations totalling 3 orbits with the ACS/SBC in the far-UV (F115LP & F165LP filters), the WFC3/UVIS in the near-UV (F300X filter) and optical g (F475W filter), and the WFC3/IR in the near-IR H (F160W filters) bands. We request that the XMM-Newton and HST observations take place within +/- 7 days of each other if possible. We have split the HST observations into two visits (one containing all the ACS/SBC exposures and the other the WFC3 UVIS/IR exposures) to aid in schedulability of the program. Our exposure times were dictated by the overheads for each exposure rather than exposure times necessary to obtain sufficient S/N. As such, a reduction in the orbital visibility period for each orbit would not negatively impact our program, so long as each exposure (if trimmed down to the overhead value) still fits within the specified orbit.
