      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 

      Windhorst, R.A.; Cohen, S.H.; Mechtley, M.; Rutkowski, M.J.; Hathi, N.P.; McCarthy, P.J.; Seibert, M.; Ryan, R.E.; Yan, H.; Baldry, I.K.; Driver, S.P.; Hill, D.T.; Kelvin, L.S.; Robotham, A.S.G.; Frogel, J.A.; Koekemoer, A.M.; Bond, H.E.; Bushouse, H.; MacKenty, J.W.; Mutchler, M.; Whitmore, B.C.; O'Connell, R.W.; Straughn, A.N.; Kimble, R.A.; Tuffs, R.J.; Balick, B.; Calzetti, D.; Silk, J.I.; Crockett, M.; Kaviraj, S.; Disney, M.J.; Dopita, M.A.; Hall, D.N.B.; Holtzman, J. 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, ...

    • Newborn spheroids at high redshift : When and how did the dominant, old stars in today's massive galaxies form? 

      Kaviraj, S.; Silk, J.; Ellis, R.S.; Cohen, S.; Windhorst, R.A.; Peirani, S.; O'Connell, R.W.; Whitmore, B.C.; Ryan Jr., R.E.; Hathi, N.P.; Dopita, M.A.; Frogel, J.A.; Dekel, A. (2013-01-11)
      We study ~330 massive (M > 10M), newborn spheroidal galaxies (SGs) around the epoch of peak star formation (1 <z <3) to explore the high-redshift origin of SGs and gain insight into when and how the old stellar populations ...

    • A panchromatic catalog of early-type galaxies at intermediate redshift in the Hubble Space Telescope wide field camera 3 early release science field 

      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 ...

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

      Ryan Jr., R.E.; McCarthy, P.J.; Cohen, S.H.; Rutkowski, M.J.; Mechtley, M.R.; Windhorst, R.A.; Yan, H.; Hathi, N.P.; Koekemoer, A. M.; Bond, H.E.; Bushouse, H.; MacKenty, J.; Mutchler, M.; Whitmore, B.C.; O'Connell, R.W.; Balick, B.; Calzetti, D.; Crockett, R.M.; Kaviraj, S.; Silk, J.I.; Disney, M.; Dopita, M.A.; Frogel, J.A.; Hall, D.N.B.; Holtzman, J. A.; Kimble, R.A.; Paresce, F.; Saha, A.; Trauger, J.; Walker, A.R.; Young, E. (2012-04-10)
      We present the size evolution of passively evolving galaxies at z 2 identified in Wide-Field Camera 3 imaging from the Early Release Science program. Our sample was constructed using an analog to the passive BzK galaxy ...

    • A WFC3 study of globular clusters in NGC 4150 : An early-type minor merger 

      Kaviraj, S.; Mark Crockett, R.; Silk, J.; Whitmore, B.C.; Mutchler, M.; O'Connell, R.W.; Windhorst, R.A.; Rejkuba, M.; Yi, S.; Frogel, J.A.; Calzetti, D. (2012-05-01)
      We combine near-ultraviolet (NUV; 2250 Å) and optical (U, B, V, I) imaging from the Wide Field Camera 3 (WFC3), on-board the Hubble Space Telescope (HST), to study the globular cluster (GC) population in NGC 4150, a sub-L* ...
