    • Clustering of K-selected galaxies at 2 < z < 3.5: Evidence for a color-density relation 
      Quadri, Ryan; van Dokkum, Pieter; Gawiser, Eric; Franx, Marijn; Marchesini, Danilo; Lira Teillery, Paulina; Rudnick, Gregory; Herrera, David; Maza Sancho, José; Kriek, Mariska; Labbé, Ivo; Francke Henriquez, Harold (UNIV CHICAGO PRESS, 2007-01-01)
      We study the clustering properties of K-selected galaxies at 2 < z < 3:5 using deep multiwavelength imaging in three fields from the MUSYC survey. These are the first measurements to probe the spatial correlation function ...
    • Galaxy stellar mass functions from z similar to 10 to z similar to 6 using the deepest spitzer/infrared ... 
      Stefanon, Mauro; Bouwens, Rychard J.; Labbé, Ivo; Illingworth, Garth D.; González Corvalán, Valentino Gastón; Oesch, Pascal A. (IOP, 2021)
      We present new stellar mass functions at z similar to 6, z similar to 7, z similar to 8, z similar to 9 and, for the first time, z similar to 10, constructed from similar to 800 Lyman-break galaxies previously identified ...
    • High Equivalent Width of H alpha plus [N II] Emission in z similar to 8 Lyman-break Galaxies from IRAC 5.8 ... 
      Stefanon, Mauro; Bouwens, Rychard J; Illingworth, Garth D; Labbé, Ivo; Oesch, Pascal A; González Corvalán, Valentino Gastón (IOP Publishing, 2022)
      We measure, for the first time, the median equivalent width (EW) of H alpha+[N II] in star-forming galaxies at z similar to 8. Our estimate leverages the unique photometric depth of the Spitzer/IRAC 5.8 mu m band mosaics ...
    • Mid-infrared properties and color selection for X-ray-detected active galactic nuclei in the MUSYC extended ... 
      Cardamone, Carolin N.; Urry, C. Megan; Damen, Maaike; van Dokkum, Pieter; Treister, Ezequiel; Labbé, Ivo; Virani, Shanil N.; Lira Teillery, Paulina; Gawiser, Eric (UNIV CHICAGO PRESS, 2008-06-10)
      We present the mid-infrared colors of X-ray-detected AGNs and explore mid-infrared selection criteria. Using a statistical matching technique, the likelihood ratio, over 900 IRAC counterparts were identified with a new ...
    • A near-infrared spectroscopic survey of K-selected galaxies at z similar to 2.3: Redshifts and implications ... 
      Kriek, Mariska; van Dokkum, Pieter; Franx, Marijn; Illingworth, Garth D.; Marchesini, Danilo; Quadri, Ryan; Rudnick, Gregory; Taylor, Edward N.; Schreiber, Natascha M. Foerster; Gawiser, Eric; Labbé, Ivo; Lira Teillery, Paulina; Wuyts, Stijn (UNIV CHICAGO PRESS, 2008-04-10)
      Using the Gemini Near-Infrared Spectrograph (GNIRS), we have completed a near-infrared spectroscopic survey for K-bright galaxies at z similar to 2.3 selected from the MUSYC survey. We derived spectroscopic redshifts from ...
    • Spectroscopic identification of massive galaxies at z similar to 2.3 with strongly suppressed star formation 
      Kriek, Mariska; van Dokkum, Pieter; Franx, Marijn; Quadri, Ryan; Gawiser, Eric; Herrera, David; Illingworth, Garth D.; Labbé, Ivo; Lira Teillery, Paulina; Marchesini, Danilo; Rix, Hans-Walter; Rudnick, Gregory; Taylor, Edward N.; Toft, Sune; Urry, C. Megan; Wuyts, Stijn (UNIV CHICAGO PRESS, 2006-10-01)
      We present first results of a spectroscopic survey targeting K-selected galaxies at using the Gemini z = 2.0 - 2.7 near-infrared spectrograph (GNIRS). We obtained near-infrared spectra with a wavelength coverage of 1.0 - ...
    • Star formation in distant red galaxies: Spitzer observations in the Hubble Deep Field-South 
      Webb, Tracy M. A.; van Dokkum, Pieter; Egami, Eiichi; Fazio, Giovanni; Franx, Marijn; Gawiser, Eric; Herrera, David; Huang, Jiasheng; Labbé, Ivo; Lira Teillery, Paulina; Marchesini, Danilo; Maza Sancho, José; Quadri, Ryan; Rudnick, Gregory; Werf, Paul van der (UNIV CHICAGO PRESS, 2006-01-01)
      We present Spitzer 24 mu m imaging of 1.5 < z < 2.5 distant red galaxies (DRGs) in the 10' x 10' extended Hubble Deep Field-South of the Multiwavelength Survey by Yale-Chile. We detect 65% of the DRGs with K-AB < 23.2 mag ...
