From our study of previous X-ray/optical spectra and of UV photometric data, we infer that the lack of BLR in this peculiar object may be attributed to ether (i) the lack of hard X-ray emission or (ii) an evolutionary scenario in which the BLR are just forming. Recent Swift pointings have revealed the emergence of hard X-rays in GSN 069, making the proposed observation highly timely. GSN 069 may represent a true Rosetta stone with which to follow the formation and early evolution of the X-ray corona and to study the connection between X-rays and the BLR/disc-wind system. ------------------------------------------------------------------------------------ Observations Description ------------------------ The target is a bona-fide true Seyfert 2 galaxy candidate with unabsorbed and ultra-soft X-ray spectrum, but with a type 2 optical spectrum that was obtained quasi-simultaneously with the X-ray observation. From our study of previous X-ray/optical spectra and of UV photometric data, we infer that the lack of BLR in this peculiar object may be attributed to ether (i) the lack of hard X-ray emission or (ii) an evolutionary scenario in which the BLR are just forming. Recent Swift pointings have revealed the emergence of hard X-rays in GSN 069, making the proposed observation highly timely. GSN 069 may represent a true Rosetta stone with which to follow the formation and early evolution of the X-ray corona and to study the connection between X-rays and the BLR/disc-wind system. We plan to perform spectroscopic observations of the Active Galactic Nucleus in the galaxy 6DFGS-GJ011908.7-341131 (a.k.a. GSN069) with the STIS-MAMA using the G230L spectral element in the NUV and the G140L one in the FUV. In both cases, we shall use the 52x0.5 aperture. Of the 3 HST orbits assigned to our program, we devote the first to the target acquisition (point-source) and to the G230L observation. The remaining 2 orbits are devoted to the G140L observations. With the HST observation, we will be able to obtain line fluxes and profiles 13815( 2) - 23-Jul-2014 13:59:38 - [ 2] for high-ionization emission lines such as Civ and for low-ionization ones such as Mgii. The spectra will be used to look for weak broad components that may reveal the early stages of the formation of the BLR or of an associated wind/outflow. The HST observation is part of an XMM-Newton approved program and we aim at obtaining quasi-simultaneous HST/STIS and XMM-Newton data, although this is a preferred scheduling, not a strict science requirement. The HST scheduling should ideally be coordinated with the approved XMM-Newton observation (XMM-Newton proposal # 074096, PI: G. Miniutti): we would like to observe the target with HST and with XMM-Newton as simultaneously as possible. We do not set a precise time range, as this is only a preferred scheduling, not a strict requirement. In any case, if simultaneity is not possible, we prefer the XMM-Newton observation to be carried first, and the HST observation to be performed later, with as short as possible a delay. Again, no requirement, just a preferred scheduling. ------------------------------------------------------------------------------------ 13815( 2) - 23-Jul-2014 13:59:38 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 6DFGS-GJ0119 GALAXY, BLR, NUCLEUS, RA=01H19M8.6400S, J2000 Z = V = 15.5 +/- 0.5 Bj~16.2, R~15.3, 08.7-341131 SEYFERT DEC=-34D11'30.45" 0.018186 E(B-V)~0.044 Reference Frame: ICRS Comments: To be coordinated with approved XMM-Newton observation (XMM-Newton proposal # 074096, PI: G.
