Lehnert Centre de Recherche Astrophysique de Lyon N ------------------------------------------------------------------------------------ Abstract Powerful radio galaxies have been unique probes of the distant Universe for many decades. This proposal requests WFC3 G141 grism with F140W pre-imaging observations to confirm an emission line observed at 1.15 microns. A high continuum flux longward of this line (seen with the G141 grism and broad-band photometry) would confirm that this line is Lyman-alpha and hence this radio galaxy at z=8.45. This detection would be the most distant super-massive black hole (SMBH) and active galactic nucleus (AGN) known. At this redshift the radio galaxy would lie at the centre of a highly ionised Stromgren sphere with contributions to the ionising flux from the accretion onto the SMBH, inverse Compton emission from the jets, and star-formation. As well as reaffirming the redshift of the host and challenging models of black hole formation, these observations will potentially reveal the complex interaction of this radio-loud AGN with its local environment. Furthermore, confirmation of the existence of a luminous radio galaxy within the Epoch of Reionisation would allow studies of neutral hydrogen from absorption of the 21 cm line. Due to the transmission of the Earth's atmosphere at 1.15 microns, this observation would take >40 times longer if conducted from the ground (eight times longer if the spectrum is binned to the resolution of the G141 grism). ------------------------------------------------------------------------------------ Observations Description ------------------------ The aim of this proposal is to confirm the redshift of a candidate ultra-high redshift radio galaxy. Previous G102 observations suggest a line at 1.15um which may be Lyman-alpha. SED modelling supports this assertion. These G141 observations aim to (a) confirm this line and (b) confirm the interpretation that this line is Lyman-alpha (by detecting continuum and other lines longward of it). 16662( 3) - 05-Oct-2021 14:20:59 - [ 2] Our proposal consists of four orbits of G141 imaging with the F140W band as pre-imaging. As well as being ideal for the G141 grism, the F140W band supports the imaging we obtained previously with F098M and F105W. The four orbits are split into two orientations to provide redudancy and each orientation restricted to prevent contamination of the sprectrum by an adjacent target. These observations should not be impacted by a gyro failure (other than their schedulability). There are no time restraints. ------------------------------------------------------------------------------------ 16662( 3) - 05-Oct-2021 14:20:59 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 GLEAMJ091734 GALAXY, HIGH REDSHIFT RA=09H17M34.4200S +/- 0.2", J2000 F105W = 0.60+/-0.02 uJy -001243 GALAXY, RADIO GALAXY DEC=-00D12'42.50" +/- 0.2" Reference Frame: ICRS Comments: Redshift unknown, possible z~8 ------------------------------------------------------------------------------------------------------------------------------------ 16662( 3) -
