Perlman Florida Institute of Technology N ------------------------------------------------------------------------------------ Abstract The nearby galaxy M87 is the prototype for low-power radio-loud FR1-type AGN, the parent population of BL Lac type blazars. Despite its proximity, brightness, and nearly a century of observations, the physical picture of how the AGN emission is fueled and what is causing the bright and variable emission in the core of M87 is still mysterious. Recent COS observations show a complex and variable line profile and weak UV continuum with hints of spatial structure (Danforth et al. 2016). Consistent with recent X-ray observations, we find little accreting gas inside the Bondi radius. We propose to resolve and precisely locate the ionizing continuum and Ly alpha line-emitting structures with long-slit far-UV STIS spectra of the nucleus. These observations will also allow us to confirm (or not) the density-bounded nature of the line emission. Along with the spatially-resolved spectroscopy, we will use multi-epoch, high-S/N COS aperture spectroscopy to address the mystery of what powers this common yet poorly-understood class of active galaxies. ------------------------------------------------------------------------------------ Observations Description ------------------------ We request two visits of five orbits each to observe the nucleus of M87. The two visits will be planned such that the STIS slit is placed along the axis of the relativistic jet during one visit and perpendicular to it on the other. Four orbits of each five-orbit visit will be devoted to spatially-resolved STIS/G140M spectroscopy with the 52x0.2" slit. The final orbit for each case will aquire sensitive COS/G130M data to obtain high-S/N measurements of the Lya profile and wings as well as metal-line emission. We base our exposure time requirements on the lowest flux component of the Cycle 21 COS spectrum. In that spectra (as well as those obtained by FOS in 1997), the continuum flux was approximately 10^-15 erg/cm2/Ang. The STIS ETC gives a S/N~4 per unbinned pixel for a 10 ksec exposure (~4 orbits). The red and blue Lya emission components were observed at (3-5)x10-15 in 2014. Four orbits at this level should provide S/N=7-10 per unbinned resel. Even if the line emission varies considerably, we will have usable data. The data will be extracted at full spatial and spectral resolution though for some applications, we will resample the line spread function to better match the COS/G130M resolution. Line profile fitting will be accomplished in much the same manner 14631( 10) - 27-Mar-2017 10:45:37 - [ 2] as was used for our Cycle 21 COS data. Based on the observed continuum and line fluxes from our Cycle 21 COS observations, a single exposure of ~2500 seconds with the sensitive COS/G130M grating will give S/N~5 per resolution element. ------------------------------------------------------------------------------------ 14631( 10) - 27-Mar-2017 10:45:37 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 M-87 GALAXY, ELLIPTICAL, RA=12H30M49.4234S +/- 0.0006", J2000 V = 8.63 JET, NUCLEUS, RADIO DEC=+12D23'28.04" +/- .0006" GALAXY Reference Frame: ICRS Extended: NO Comments: This object was generated by the target selector and retrieved from the SIMBAD database.
