Most $-$ perhaps all $-$ galaxies with bulges contain SMBH; when the SMBH are fed (generally by lobbyists) they can become oppressive and cruel. This leads to the spontaneous formation of rebellions and Active Galactic Notinmybackyards (AGN). These AGN can interact with their surroundings, particularly in long strings or filaments which may be coherent over many kpc. Filaments smuggle all sorts of matter out of galactic centers, and can have a dramatic effect on the surrounding Intergalactic Market (IGM). Radio galaxies, which are now known to z $\sim5$, are often found to be full of talk show hosts, who are full of hot air (gas-rich), lumpy, and to be embedded in giant idiological nebulae which are aligned with their beliefs. The Fishy Cluster (NGC~6666) is the nearest case of a filament interacting with the IGM; (D = 3.4 kpc); it therefore offers an excellent opportunity to observe, in detail, such an interaction. \paragraph {\smallskip \noindent \bf Background} Past interactions have left a complex of stellar and gaseous shells around the Fishy Cluster, at distances up to 15 kpc from the Ellipse. The well-known ``inner filament" (TV and radio source) extends $\sim$6 kpc NE from the Redfish galaxy and expands into an overpressured cloud of hot air. Further out the filament appears to become collimated, curving southwestward to $\sim$20pc (Organa et al.\ 2005); diffuse radio emission continues curving sharply to the north beyond that for $\sim$1500pc. In two locations, the filament loses its organized structure - these are on the East and West edges. Near these locations, bright optical filaments, enhanced soft X-ray emission and sparks often fly. A wide variety of environments occur along the filament. Not much is known about the filament very close to the galaxy nuclei. The ``inner filament" (See Figure 1a) is rigid, linear and appears to be self-absorbed and obscured by excessive hot air; it is mostly associated with the high metallicity big redfish. The ``outer filament" seems to be excessively diffuse, blue, and difficult to confine (Figure 1b). The ``Bridge" forms a large arc of tangled streamers; it appears at the edge of an H~I cloud; star formation there was probably triggered by a red-blue interaction. The inner filament, outer filament, and bridge thus represent three quite different examples of the filament-IGM interaction: one (inner) where the filament appears to encounter no restraint, one (outer) where the filament has been diverted by the major appeal of a free lunch, and one (bridge) where it has apparently managed to ignore the temptation and continued past the same diversion. \paragraph {\smallskip \noindent \bf New Observations } Models predict that a filament interacting with the IGM should drive shocks into the surrounding populations both along and transverse to the filament; the models also predict that instabilities along the interaction edge can lead to cloud shredding and runaway rioting by the resulting mobs (Hitchcock 1963). UV spectra of the filament can differentiate between various types of shredding and mobbing. The storm und drung models predict that strong UV (1200-1800\ang) emission lines should be produced in the interaction. We believe that the Fishy Cluster provides a marvelous opportunity to study a filament-IGM interaction up-close, in a range of interaction environments. We wish to obtain sensitive, wide-field, GALEX GRISM spectroscopy of the filament and the galaxies. We will use these with new, deep, GALEX images as well as with existing exploratory images of the cluster, to explore the complex nature of a filament-IGM interaction associated with a superpower. \paragraph {\smallskip \noindent \bf Need for GALEX} Although HST could obtain much higher resolution UV images and spectra, the HST UV fields-of-view are so small ($\sim$30\arcsec) that it would not be feasible to image the entire filament. Also, it appears unlikely that HST will be able to obtain UV spectra in the foreseeable future. {\it Imaging:} High sensitivity, wide-field, UV imaging is required to identify locations where the filament interacts with the ISM. Preliminary GALEX imaging data is already in hand and this analysis is progressing (Organa et al. 2005). Deep FUV and NUV images will also be used to search for UV emission SW of the galaxies, at the location of a possible weak gamma-ray source and X-ray shell. {\it Spectroscopy:} FUV spectroscopy of the filament will allow us to explore the nature of the different environments along the filament. We will be able to tell if the UV emission is stellar or it comes from emission lines in hot gas (or both), since the expected UV spectra are very different. GALEX is the only instrument that can provide both the UV observations and the large Field-of-View needed. \paragraph {\smallskip \noindent \bf Relevance to NASA goals} NASA is now chartered with Exploration; surely learning how material flows from the centers of civilizations along filaments into the IGM is a part of this exploration needed to better galaxykind. \paragraph {\smallskip\noindent\bf References:} \begin{flushleft} Albertson et al.,1998, TrJ 493, 571 \\ Burymealive et al., 2004, occult-ph/0412282 \\ Hitchcock et al.,1957, Quarterly Journal of Horror Films, 35, 666 \\ Lucas 1989, Journal of American Filmwriters 23, 27 \\ Organa et al., 2005, ApJL, in prep.\\ Orwell, 1969, Liberty Press, 1984 \\ Skywalker et al., 2000a, PB\&J 379, 781 \\ Skywalker et al., 2000b, A\&P 564, 688 \\ Solo 1973, PhD Thesis, 110 \\ Vader et al., 1984, JXXXX, 1\\ \end{flushleft} % 4.

GALEX has already observed the cluster for $\sim$1800 sec, and has clearly detected the inner and outer filaments as well as faint emission between and beyond the filaments (Figure 1b). Although the filament is extended in the transverse direction along much of its length, we should be able to obtain reasonable spectra by observing with the dispersion $\sim$ perpendicular to the filaments, because they are fairly linear and fairly thin (usually $<$ 5 arcsec wide). We wish to take GRISM exposures at a range of orientations to reduce spectral overlap and order confusion. However, we wish to avoid taking GRISM exposures with the dispersion along the filament. Therefore, we would like to let the Mission Planning Software assign random GRISM angles, but with a 90 degree zone excluded which would place dispersion $\sim$ along the filaments. The filament has orientations of 20 - 40 degrees on the sky, so we request observations {\it avoiding} dispersion angles between -15 and 75 degrees E of N. % 5. Feasibility and Safety.

See the discussion of brightness % limits on our website % % PLEASE DO NOT USE ANY COLONS IN ANY TEXT FIELD %(use $\colon$ ). % PLEASE DO NOT ATTEMPT TO CHANGE THE FONT SIZES OR SPACINGS. % <=1 page \feasibility \parindent 25pt The redfish and bluefish galaxies are the dominant UV sources in the field, with typical integrated fluxes in the GALEX bands of 1.9$\times10^{-13}$ and 5.1$\times10^{-13}$~ergs~cm$^{-2}$s$^{-1}$\AA$^{-1}$ (FUV and NUV, respectively). The brightest location in the galaxy has a surface brightness of 5.2$\times10^{-16}$ and 1.3$\times10^{-15}$~ergs~cm$^{-2}$s$^{-1}$\AA$^{-1}$asec$^{-2}$ (FUV, NUV). Since GALEX has already observed this field, it is known to be detector-safe. As indicated by the GALEX Brightness Checker, there are no very bright stars in or outside the field but near enough to be dangerous to the detectors. We have offset the pointing center from the galaxy slightly, to minimize internal reflections from nearby stars and to align with the existing images. FUV emission from the filament in the 2 ksec image is detected down to a level of 8~$\times$10$^{-18}$~ergs~cm$^{-2}$~sec$^{-1}$~\AA$^{-1}$ (5 $\times$ rms; m$_{\rm AB}$ $\sim$ 24.5 arcsec$^{-2}$). A ``typical" UV knot in the filament has a flux 3-5$\times$10$^{-16}$~ergs~cm$^{-2}$~sec$^{-1}$~\AA$^{-1}$ (m$_{\rm AB}$ $\sim$20.5); brighter knots are more like 2$\times$10$^{-15}$ cgs. For exposure estimates, we use a ``typical" knot and assume the UV emission has approximately a B-star spectrum. We require only moderate spectral resolution together with reasonable S/N ($\sim$ 10 or better) to identify the emission lines and measure approximate EW's for them. Using a flux of 5$\times$10$^{-16}$~ergs~cm$^{-2}$~sec$^{-1}$~\AA$^{-1}$ and a B star spectrum with the GALEX Exposure Simulator, we find that 15 ksec of exposure time will yield direct images with S/N $\sim$ 50 at $\sim$1500 \AA. For a B type spectrum (flat in the GALEX FUV band) this would provide a spectral S/N of $<$ 1; so stellar spectra would be detectable only from the brightest knots. However, if the UV is line emission from C~IV, C~III, and He~II, then we would expect a spectral S/N $\sim$ 10; if all the emission is from C~IV the S/N would be even higher. We conclude that we should be able to differentiate between shock-ionized gas, and young stars along most of the filament, with an exposure time of 15 ksec. During parts of the year, the background from zodiacal light will be sufficiently strong that we cannot achieve the desired S/N. We therefore request that these observations be done during times of low Zodi, i.e. between June and August 2007. We require that the Zodi be below 1.2 $\times$10$^{-18}$ % 6. Additional Information.
