McLin Sonoma State University N ------------------------------------------------------------------------------------ Abstract We propose to exploit the flaring states of high- and unknown-redshift blazars to obtain very high S/N > 25 COS spectra in order to study details of the local intergalactic medium (IGM) not accessible for study using the plethora of lower S/N data being obtained. Only with very high S/N spectra is it possible to detect the weakest Ly alpha and metal lines wherein may lie a substantial portion of the cosmic baryons. The numbers of weak OVI absorbers can discriminate between collisionally ionized and photoionized models, as well as determine which of several galactic outflow models best matches the IGM metal enrichment. Most importantly, high S/N spectra plus the featureless UV power-law continuum of blazars facilitates the detection of broad, shallow absorbers ["broad Ly alpha" (BLA) and broad OVI-only absorbers] which uniquely probe the T = 3 x 10^5 - 3 x 10^6 K range in the IGM where many cosmic baryons are predicted to be "hiding." In addition, these same spectra will be used to obtain lower limits on, or estimates of, the redshift for any featureless blazars observed using the foreground Ly-alpha forest absorbers. In some cases weak Lyman alpha emission may also be detected, as was recently discovered for a few well-known low-redshift BL Lac objects using COS spectra. We request up to three *non-disruptive ToOs* to carry out this program in Cycle 19. Ground-based monitoring will select objects flaring to V ~ 13.5 mag for HST observations, out of a set of about 200 monitored blazars. ------------------------------------------------------------------------------------ Observations Description ------------------------ We have selected our targets from several pools of known blazars. The First group (12) are objects with known or suggested emission redshifts > 0.3 to maximize the pathlength for weak intergalactic Lya, O VI, and other important diagnostic lines. The second group (6) 13008( 9) - 12-Dec-2013 12:58:15 - [ 2] are objects known to be simultaneously bright in TeV gamma-rays and with nominal UV |*|uxes above ~1e-15 erg cm-2 s-1 Ang-1. All targets have measured GALEX NUV and FUV |*|uxes and are in regions of moderate to low Galactic extinction. We assume the unreddened continuum in the optical-UV range follows a power-law be- havior of the form f(nu)=nu^-alpha and determine the slope alpha from published GALEX NUV/FUV fluxes. These fluxes were obtained simultaneously and their ratio should be insensitive to luminosity variations in the AGN. Observed GALEX UV indices are 0 < alpha < 2, typical of those seen in detailed UV spectra of BL Lac objects (e.g., Stocke, Danforth & Perlman 2011). All targets will be monitored on the ground by a network of small, optical telescopes (see Coordinated Observations below) with a ~3 day cadence. We estimate optical trigger thresholds for each target based on these power laws and the observed Galactic extinction toward each object. When the optical magnitude indicates that the reddened |*|ux in the far- UV is ~(2-3)e-14 erg cm-2 s-1 Ang-11, we will activate a non-disruptive ToO observation. The typical magnitude for triggering these observations is V < 13.5. For F1500=3e-14 erg cm-2 s-1 Ang-1, we estimate that we can achieve S/N ~25 per resolution element in a single five-orbit HST visit. The observations will be carried out in both COS/G130M (~2 orbits) and COS/G160M (~3 orbits) using muliple grating central wavelength and FP positions. This is to ensure continuous spectral coverage over the 1132 < lambda < 1795 wavelength range and to dither instrumental features (repellor grid wire shadows, gain sag artifacts, etc.) across the spectrum. Two members of the team have extensive experience in this area as members of the COS GTO team. Unfortunately, we cannot guarantee that any particular object will remain above our flare threshold for the 2-4 weeks required for Preferred Scheduling observations (a.k.a. non- disruptive ToO). To minimize the chances of a miss, we will carefully examine the his- torical variability record for each object and the trend of the flare in progress to predict the duration of a flare. However, even if our chosen blazar has faded somewhat below our F1500~3e-14 erg cm-2 s-1 Ang-1 trigger level, we can still obtain very useful data at lower 13008( 9) - 12-Dec-2013 12:58:15 - [ 3] S/N with our planned observations. As a case in point, 1ES 1553+113 was observed in a non-flaring state (3 HST orbits, F1500~1.5e-14, S/N ~ 15). Danforth et al. (2010) published a study of over 100 intervening absorption lines, including several interesting new OVI absorbers, and constrained the source redshift to 0.3950 < z < 0.45. Even if the objects are not near peak flux during the HST observations, our data (obtained at an above-average flux level) will enable compelling and original science.
