Evidence for a Non-Uniform Initial Mass Function in the Local Universe

Gerhardt R. Meurer, O. I. Wong, J. H. Kim +21

Many results in modern astrophysics rest on the notion that the Initial Mass Function (IMF) is universal. Our observations of HI selected galaxies in the light of H-alpha and the f…

The Dearth of UV-Bright Stars in M32: Implications for Stellar Evolution Theory

Thomas M. Brown, Ed Smith, Henry C. Ferguson +3

Using the Space Telescope Imaging Spectrograph on the Hubble Space Telescope, we have obtained deep far-ultraviolet images of the compact elliptical galaxy M32. When combined with…

Age Constraints for an M31 Globular Cluster from Main Sequence Photometry

Thomas M. Brown, Henry C. Ferguson, Ed Smith +5

We present a color-magnitude diagram (CMD) of the globular cluster SKHB-312 in the Andromeda galaxy (M31), obtained with the Advanced Camera for Surveys on the Hubble Space Telesco…

The Nature of Faint 24 micron Sources Seen in Spitzer Observations of ELAIS-N1

R. Chary, S. Casertano, M. E. Dickinson +7

The Spitzer Space Telescope has undertaken the deepest ever observations of the 24 micron sky in the ELAIS-N1 field as part of GOODS Science Verification observations. We present t…

Type Ia Supernova Discoveries at z>1 From the Hubble Space Telescope: Evidence for Past Deceleration and Constraints on Dark Energy Evolution

Adam G. Riess, Louis-Gregory Strolger, John Tonry +16

We have discovered 16 Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to provide the first conclusive evidence for cosmic deceleration that pre…

Morphologies and Spectral Energy Distributions of Extremely Red Galaxies in the GOODS-South Field

Leonidas A. Moustakas, Stefano Casertano, Chris Conselice +12

Using U'- through Ks-band imaging data in the GOODS-South field, we construct a large, complete sample of 275 ``extremely red objects'' (EROs; K_s<22.0, R-K_s>3.35; AB), all with d…
