----- Attempting Submission 1 (Thu Aug 28 21:03:39 GMT 2008) ----- ----- Attempting Submission 2 (Fri May 22 13:29:42 GMT 2009) ----- We aim to detect and measure the ionization state and outflow velocities in the well-studied low-BH-mass AGN NGC 4051. We have been granted a 340 ks Suzaku observation to study continuum and low-resolution line spectral variability; HETG spectroscopy complements this by isolating narrow absorption lines arising from key zones of gas, allowing us to measure ionization, column and outflow velocities of the multiple ionized zones. A moderately ionized zone in particular can mimic the appearance of a broad Fe emission line but can be revealed by 6.5 keV Fe Kalpha absorption, for which there is already tentative evidence. A 320 ks HETG exposure will provide powerful diagnostic signatures across a wide range of ionisation. We also request HST time for tie-in UV spectroscopy.

We will obtain G130M and G160M spectra of the nucleus of NGC 4051 during a single visit. Two orbits will be used to obtain G130M spectra at two different wavelength settings, to cover the wavelength gap. The same will be done with the G160M spectra, resulting in a total of 4 orbits.
