A.; Kimble, R.A.; McCarthy, P.J.; Paresce, F.; Saha, A.; Trauger, J.T.; Walker, A.R.; Windhorst, R.A.; Young, E.T.; Jeong, H.; Yi, S.K. (2011-02-01)
      We present a spatially resolved near-UV/optical study, using the Wide Field Camera 3 (WFC3) on board the Hubble Space Telescope, of NGC 4150, a sub-L , early-type galaxy (ETG) of around 6 × 10 M , which has been observed ...

    • The Hubble Space Telescope wide field camera 3 early release science data : Panchromatic faint object counts for 0.2-2 μm wavelength

A.; Paresce, F.; Saha, A.; Trauger, J.T.; Walker, A.R.; Young, E.T. (2011-04-01)
      We describe the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) Early Release Science (ERS) observations in the Great Observatories Origins Deep Survey (GOODS) South field. The new WFC3 ERS data provide calibrated, ...

      Rutkowski, M.J.; Cohen, S.H.; Windhorst, R.A.; Kaviraj, S.; Crockett, R.M.; Silk, J.; O'Connell, R.W.; Hathi, N.P.; McCarthy, P.J.; Ryan Jr., R.E.; Koekemoer, A.; Bond, H.E.; Whitmore, B.C.; Yan, H.; Kimble, R.A.; Balick, B.; Calzetti, D.; Disney, M.J.; Dopita, M.A.; Frogel, J.A.; Hall, D.N.B.; Holtzman, J. A.; Paresce, F.; Saha, A.; Trauger, J.T.; Walker, A.R.; Young, E.T. (2012-03-01)
      In the first of a series of forthcoming publications, we present a panchromatic catalog of 102 visually selected early-type galaxies (ETGs) from observations in the Early Release Science (ERS) program with the Wide Field ...

    • PDS 144: the first confirmed Herbig Ae-Herbig Ae wide binary 

      Hornbeck, J. B.; Grady, C. A.; Perrin, M. D.; Wisniewski, J. P.; Tofflemire, B. M.; Brown, A.; Holtzman, J. A.; Arraki, K.; Hamaguchi, K.; Woodgate, B.; Petre, R.; Daly, B.; Grogin, N. A.; Bonfield, David; Williger, G. M.; Lauroesch, J. T. (2012-01-01)
      PDS 144 is a pair of Herbig Ae stars that are separated by 5.'' 35 on the sky. It has previously been shown to have an A2Ve Herbig Ae star viewed at 83 degrees inclination as its northern member and an A5Ve Herbig Ae star ...

    • The size evolution of passive galaxies : observations from the Wide-Field Camera 3 Early Release Science program
