Receipt: # 17892-3 ----- Attempting Submission 4 (Fri Dec 06 21:48:12 GMT 2024) ----- A Coordinated UV and X-ray Reverberation Study of NGC 4151 at High Spectral Resolution The proximity of NGC 4151 leads to especially sensitive line diagnostics; for this reason, it has always been at the forefront of reverberation studies. Early observations of NGC 4151 in X-rays have revealed a complex Fe K-alpha line, and confirmed that the line flux likely responds to the continuum in the manner that optical and UV lines respond. As a result, XRISM will undertake a monitoring campaign in Cycle 1 to clearly measure the line response and map the accretion flow. A simultaneous UV campaign with Hubble will reveal the relative positions of the emission line geometries, and can also reveal the relationship between winds seen in absorption. We request a series of STIS observations between 12 and 31 December 2024 in order to create a uniquely powerful data set with legacy value to both missions. We will obtain UV spectra of the Seyfert galaxy NGC 4151 through 9 orbits, monitoring time variability in parallel with the reverberation mapping campaign with XRISM Resolve. This encompasses the major broad lines visible in a typical AGN spectrum: Ly alpha, N V 1240, Si IV 1400, C IV 1550, He II 1640, C III] 1909, and Mg II 2798. We calculated the required exposure times with the HST ETC, with the 3E-13 erg/s/cm2/A at lambda~2240A, using the built in template of the Type-1 Seyfert Galaxy Mrk231. With a time of 200 seconds per orbit for G140L, and 100 seconds per orbit for G230LB, respectively, the S/N ratio (~50) will be sufficient. The time required for target acquisition with the F28X50LP aperture is less than 0.1 seconds, which is the minimum assignable time.
