Spectroscopic Gravitational Lensing and Limits on the Dark Matter Substructure in Q2237+0305
R. B. Metcalf, L. A. Moustakas, A. J. Bunker +1
Spatially resolved spectroscopic data from the CIRPASS integral field unit (IFU) on Gemini are used to measure the gravitational lensing of the 4-image quasar Q2237+0305 on differe…
Photometric Redshifts for Galaxies in the GOODS Southern Field
B. Mobasher, R. Idzi, N. Benitez +28
We use extensive multi-wavelength photometric data from the Great Observatories Origins Deep Survey (GOODS) to estimate photometric redshifts for a sample of 434 galaxies with spec…
A Possible New Population of Sources with Extreme X-Ray / Optical Ratios
Anton M. Koekemoer, D. M. Alexander, F. E. Bauer +13
We describe a possible new class of X-ray sources that have robust detections in ultra-deep Chandra data, yet have no detections at all in our deep multi-band GOODS Hubble Space Te…
