OBSERVATIONS OF RADIO GALAXY MRC 1138-262: MERGING GALAXIES EMBEDDED IN A GIANT Lyα HALO
The radio galaxy MRC 1138-262 at z = 2.16 is most likely a brightest cluster galaxy in an early stage of evolution. Here we present observations of the luminous emission line halo and the stellar components of this radio galaxy. Optical narrow band imaging shows a very extended (∼ 160 kpc) and luminous Lyα halo. Infrared narrow band imaging reveals a much smaller Hα halo with a morphology very ...
متن کاملPlausible Fluorescent Lyα Emitters around the Z = 3.1 Qso0420-388
We report the results of a survey for fluorescent Lyα emission carried out in the field surrounding the z = 3.1 quasar QSO0420-388 using the FORS2 instrument on the VLT. We first review the properties expected for fluorescent Lyα emitters, compared with those of other non-fluorescent Lyα emitters. Our observational search detected 13 Lyα sources sparsely sampling a volume of ∼ 14000 comoving Mp...
متن کاملReionization and Galaxy Evolution Probed by Z = 7 Lyα Emitters
We made a narrowband NB973 (bandwidth of 200Å centered at 9755Å) imaging of the Subaru Deep Field (SDF) and found two z = 7 Lyα emitter (LAE) candidates down to NB973 = 24.9. Carrying out deep follow-up spectroscopy, we identified one of them as a real z = 6.96 LAE. This has established a new redshift record, showing that galaxy formation was in progress just 750 Myr after the Big Bang. Meanwhi...
متن کاملUnderstanding Lyα emitters
This publication contains the conference summary of the Understanding Lyα Emitters conference held at the Max Planck Institute for Astronomy in Heidelberg October 6 10, 2008. The scope of the conference was to bring together most of the scientists working in the field of Lyα emitters, whether at low or high redshift, or on observational or theoretical aspects, and to summarise how far the field...
متن کاملA study of distant Lyα emitters in overdense regions
Recently, we conducted a Very Large Telescope (VLT) large program to search for forming clusters by looking for overdensities of Lyα emitters around high redshift radio galaxies. In total seven proto-clusters were discovered, including a protocluster around the radio galaxy MRC 0316–257 at z ∼ 3.13. This structure has an excess of Lyα emitters by a factor of 3 as compared to the field, and the ...
