  • The disappearance of Lyα blobs: a GALEX search at z=0.8 

    Keel, William C.; III., Raymond E. White; Chapman, Scott; Windhorst, Rogier A. (2009-07-13)
    Lyman alpha blobs - luminous, spatially extended emission-line nebulae, often lacking bright continuum counterparts - are common in dense environments at high redshift. Until recently, atmospheric absorption and filter ...

  • Evidence for a Major Merger Origin of High Redshift Sub-millimeter Galaxies 

    Conselice, Christopher J.; Chapman, Scott C.; Windhorst, Rogier A. (2003-10-10)
    Sub-mm detected galaxies located at redshifts $z > 1$ host a major fraction of the bolometric luminosity at high redshifts due to thermal emission from heated dust grains, yet the nature of these objects remains a mystery. ...

  • The Infrared Counterparts of the Optically Unidentified CDF-S 1Ms Sources 

    Yan, Haojing; Windhorst, Rogier A.; Rottgering, Huub J. A.; Cohen, Seth H.; Odewahn, Stephen C.; Chapman, Scott C.; Keel, William C. (2003-03)
    The Chandra Deep Field South (CDF-S) 1Ms exposure produced a catalog of 346 X-ray sources, of which 59 were not visible on the VLT/FORS1 and the ESO-MPI/WFI deep R-band images to a limit of R_{vega}=26.1--26.7 mag. Using ...
