(Oxford University PressRoyal Astronomical Society, 2014)We study the angular clustering of z ∼ 2 galaxies using ∼40 000 star-forming (SF) and ∼5000 passively evolving (PE) galaxies selected from ∼2.5 deg[superscript 2] of deep (K[subscript lim] = 23–24 AB) Canada–France–Hawaii ...
-
(American Astronomical SocietyIOP Publishing, 2015-06-10)We report the first direct and robust measurement of the faint-end slope of the Ly[alpha] emitter (LAE) luminosity function (LF) at z = 5.7. Candidate LAEs from a low-spectral-resolution blind search with IMACS on ...
-
(American Astronomical Society, 2008-11-10)We present the first results of a search for Ly[alpha] emitters (LAEs) in the DEEP2 spectroscopic database that uses a search technique that is different from but complementary to traditional narrowband imaging surveys.We ...
-
(American Astronomical Society, 2011-10-20)We report results of an unprecedentedly deep, blind search for Ly[alpha] emitters (LAEs) at z = 5.7 using the Inamori-Magellan Areal Camera & Spectrograph (IMACS), with the goal of identifying missing sources of reionization ...
-
(Royal Astronomical SocietyOxford University Press, 2007)We report the ultraviolet luminosity function (UVLF) of Lyman break galaxies at z∼5 derived from a deep and wide survey using the prime focus camera of the 8.2 m Subaru telescope (Suprime-Cam). Target fields consist of two ...
-
(American Astronomical SocietyIOP Publishing, 2012-01-10)Using new Keck DEIMOS spectroscopy, we examine the origin of the steep number counts of ultra-faint emission-line galaxies recently reported by Dressler et al. We confirm six Ly[alpha] emitters (LAEs), three of which have ...
-
(American Astronomical SocietyIOP Publishing, 2007-12)The Canada-France High-z Quasar Survey (CFHQS) is an optical survey designed to locate quasars during the epoch of reionization. In this paper we present the discovery of the first four CFHQS quasars at redshifts greater ...
-
(American Astronomical Society, 2005-12-10)We introduce a very deep, R[subscript lim] ~ 27, multicolor imaging survey of very faint star-forming galaxies at z ~ 4, 3, 2.2, and 1.7. This survey, carried out on the Keck I telescope, uses the very same U[subscript ...
-
(American Astronomical SocietyIOP Publishing, 2011-08-20)We investigate the luminosity-dependent clustering of rest-frame UV-selected galaxies at z ∼ 4, 3, 2.2, and 1.7 in the Keck Deep Fields, which are complete to R = 27 and cover 169 arcmin[superscript 2]. We find that at z ...
-
(Oxford University PressRoyal Astronomical Society, 2019-04-29)We introduce the largest to date survey of massive quiescent galaxies at redshift ζ ∼ 1.6. With these data, which cover 27.6 deg2, we can find significant numbers of very rare objects such as ultra-massive ...
-
(American Astronomical Society, 2009-10-10)We present results of optical spectroscopic observations of candidates of Lyman break galaxies (LBGs) at z ∼ 5 in the region, including the GOODS-N and the J0053+1234 regions by using Gemini Multi-Object Spectrograph North ...
-
(American Astronomical SocietyIOP Publishing, 2008-06-01)We present results from a blind, spectroscopic survey for z ~ 5.7 Ly[alpha]-emitting galaxies (LAEs) using the Inamori Magellan Areal Camera and Spectrograph. A total of ~200 arcmin[superscript 2] were observed in the ...
-
Missing stellar mass in SED fitting: spatially unresolved photometry can underestimate galaxy masses (Oxford University PressRoyal Astronomical Society, 2015)We fit model spectral energy distributions (SEDs) to each pixel in 67 nearby (= 0.0057) galaxies using broad-band photometry from the Sloan Digital Sky Survey and GALEX. For each galaxy, we compare the stellar mass ...
-
(American Astronomical SocietyIOP Publishing, 2010-08-10)We present NICMOS J[subscript 110] (rest-frame 1200–2100 [Angstrom]) observations of the three z = 5.7 Ly[alpha] emitters discovered in the blind multislit spectroscopic survey by Martin et al. These images confirm the ...
-
(American Astronomical SocietyIOP Publishing, 2012-05)The Next Generation Virgo Cluster Survey (NGVS) is a program that uses the 1 deg[superscript 2] MegaCam instrument on the Canada–France–Hawaii Telescope to carry out a comprehensive optical imaging survey of the Virgo ...
-
(American Astronomical SocietyIOP Publishing, 2014-12-20)The Next Generation Virgo Cluster Survey (NGVS) is an optical imaging survey covering 104 deg[superscript 2] centered on the Virgo cluster. Currently, the complete survey area has been observed in the u[superscript ∗] giz ...
-
(Royal Astronomical SocietyOxford University Press, 2013-08-19)We use an adaptation of the BzK[subscript s] technique to select ∼40 000 z ∼ 2 galaxies (to K[subscript AB] = 24), including ∼5000 passively evolving (PE) objects (to K[subscript AB] = 23), from 2.5 deg[superscript 2] of ...
-
(Oxford University PressRoyal Astronomical Society, 2019-03)We present the first results of our pilot study of eight photometrically selected Lyman-continuum (LyC) emitting galaxy candidates from the COSMOS field and focus on their optical emission line ratios. Observations were ...
-
(The American Astronomical SocietyIOP Publishing, 2017-11-20)The SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES) is a three-year JCMT Large Program aiming to reach the 450 μm confusion limit in the COSMOS-CANDELS region to study a representative sample of the high-redshift ...
-
(American Astronomical SocietyIOP Publishing, 2009-07-20)We present results of a spectroscopic search for Ly[alpha] emitters (LAEs) in the Cl1604 supercluster field using the extensive spectroscopic Keck/DEep Imaging Multi-Object Spectrograph database taken as part of the ...
