Ly-alpha emitting galaxies at redshift z~4.5 in the LALA Cetus field
Jun-Xian Wang, Sangeeta Malhotra, James E. Rhoads +2
We present a large sample of Ly-alpha emitting galaxies spectroscopically confirmed at z~4.5, based on IMACS spectroscopic observations of candidate LAEs in the LALA Cetus field. W…
Turning Back the Clock: Inferring the History of the Eight O'clock Arc
Steven L. Finkelstein, Casey Papovich, Gregory Rudnick +5
We present the results from an optical and near-infrared spectroscopic study of the ultraviolet-luminous z = 2.73 galaxy, the 8 o'clock arc. Due to gravitational lensing, this gala…
A Plethora of AGN Among Lyman Alpha Galaxies at Low Redshift
Steven L. Finkelstein, Seth H. Cohen, Sangeeta Malhotra +4
We investigate the fraction of z ~ 0.3 Lyman alpha emitting galaxies (LAEs) which host active galactic nucleus activity, which is typically from 1 - 5% at 2 < z < 6. Using optical…
Cepheid Calibrations of Modern Type Ia Supernovae:Implications for the Hubble Constant
Adam G. Riess, Lucas Macri, Weidong Li +9
This is the first of two papers reporting measurements from a program to determine the Hubble constant to 5% precision from a refurbished distance ladder. We present new observatio…
IRS Spectroscopy and Multi-wavelength Study of Luminous Star-forming Galaxies at z~1.9
J. -S. Huang, S. M. Faber, E. Daddi +24
We analyze a sample of galaxies chosen to have F24>0.5 mJy and satisfy a certain IRAC color criterion. IRS spectra yield redshifts, spectral types, and PAH luminosities, to which w…
Estimation of the Hubble Constant and Constraint on Descriptions of Dark Energy
Lincoln Greenhill, Elizabeth Humphreys, Wayne Hu +6
Joint analysis of Cosmic Microwave Background, Baryon Acoustic Oscillation, and supernova data has enabled precision estimation of cosmological parameters. New programs will push t…
