Receipt: # 14699-1 ----- Attempting Submission 2 (Wed Nov 23 18:14:07 GMT 2016) ----- The hosts of the early ionized bubbles: the nature and diversity of the most luminous Lyman-alpha emitters at z~6-7 The most distant sources stringently test models of early galaxy formation and of the epoch of re-ionisation. Recently, we have spectroscopically confirmed the brightest Lyman-alpha (Lya) emitters at z~7 (e.g. CR7; Sobral et al. 2015) and showed that luminous Lya emitters at z~7 (e.g. Himiko) are not as rare as previously thought. Surprisingly, we find even higher luminosity Lya emitters at z = 6.6 (Matthee et al. 2015) and at z=5.7, implying that at these high redshifts the bright end of the Lya luminosity function is likely a power-law, and certainly not a Schechter function. We are also revealing, for the first time, the potential diversity and unexpected nature of luminous Lya emitters at z~6-7. CR7 is already the subject of a wide variety of papers exploring its PopIII-like or direct collapse black hole (DCBH) nature; now is the time to study the first sample of CR7-like sources at z~6-7. Our aim is to study the first sample of ~10 luminous Lya emitters just before and after the epoch of re-ionisation, in order to unveil their nature and evolution. Are they capable of ionising their own bubbles (allowing their Lya to be observable)? Are all sources split into multiple components? What are their typical (and range of) UV luminosities and sizes? Do they always contain redder/older stellar populations, likely responsible for previously ionizing a local bubble? Can some of them be lensed? We will be able to address these questions for the first time, by obtaining WFC3 observations of MASOSA and other 9 newly discovered luminous Lya emitters at z=5.7 and 6.6 in the SA22 field and directly compare them with the same observations already done for CR7+Himiko. Follow up in rest-frame UV of bright Lyman-alpha emitters at z=6.6 and z=5.7. Some pointings contain more than one target (e.g. VR7). For VR7 observations, WFC3 needs to have the longer axis (136 arcsec) of the CCD aligned North-South, to image both sources. Two filters will be used for the z=6.6 targets (pointing centers: VR7, MASOSA, SA22WIDE-219795): F110W and F160W. Two other filters will be used for the z=5.7 targets (SSM16 targets), to probe similar rest-frame lambda: F098M and F140W.
