Searching for large-scale structures around high-redshift radio galaxies with Herschel
E. E. Rigby, N. A. Hatch, H. J. A. Röttgering +15
This paper presents the first results of a far-infrared search for protocluster-associated galaxy overdensities using the SPIRE instrument on-board the {\it Herschel} Space Observa…
GMASS ultradeep spectroscopy of galaxies at z ~ 2 - VII. Star formation, extinction, and gas outflows from UV spectra
M. Talia, M. Mignoli, A. Cimatti +13
We use rest-frame UV spectroscopy to investigate the properties related to large-scale gas outflows, and to the dust extinction and star-formation rates of a sample of z ~ 2 star-f…
An H-alpha search for over-dense regions at z=2.23
Y. Matsuda, Ian Smail, J. E. Geach +16
We present the results of a narrow-band (H2S1, 2.121/0.021um) imaging search with WFCAM/UKIRT for H-alpha emitters around several potential signposts of rare (10^-7-10^-8 Mpc^-3) o…
The clustering and evolution of H-alpha emitters at z~1 from HiZELS
David Sobral, Philip N. Best, James E. Geach +5
(Abridged) The clustering properties of a well-defined sample of 734 H-alpha emitters at z=0.84 obtained as part of the Hi-z Emission Line Survey (HiZELS) are investigated. The spa…
NIR spectroscopy of SDSS J0303-0019: a low luminosity, high Eddington ratio quasar at z~6
J. D. Kurk, F. Walter, X. Fan +4
We present sensitive near--infrared VLT ISAAC spectroscopic observations of the z=6.08 quasar SDSS J030331.40-001912.9. This QSO is more than a magnitude fainter than other QSOs at…
Bright Lyman-alpha Emitters at z~9: constraints on the luminosity function from HiZELS
D. Sobral, P. N. Best, J. E. Geach +7
New results are presented, as part of the Hi-z Emission Line Survey (HiZELS), from the largest area survey to date (1.4 sq.deg) for Lyman-alpha emitters (LAEs) at z~9. The survey,…
