The Stability of the Point Spread Function of the Advanced Camera for Surveys on the Hubble Space Telescope and Implications for Weak Gravitational Lensing
Jason D. Rhodes, Richard Massey, Justin Albert +11
(abridged) We examine the spatial and temporal stability of the HST ACS Wide Field Camera (WFC) point spread function (PSF) using the two square degree COSMOS survey. We show that…
The Purple Haze of Eta Carinae: Binary-Induced Variability?
Nathan Smith, Jon A. Morse, Nicholas R. Collins +1
Asymmetric variability in ultraviolet images of the Homunculus obtained with the Advanced Camera for Surveys/High Resolution Camera on the Hubble Space Telescope suggests that Eta…
Waiting in the Wings: Reflected X-ray Emission from the Homunculus Nebula
M. F. Corcoran, K. Hamaguchi, T. Gull +14
We report the first detection of X-ray emission associated with the Homunculus Nebula which surrounds the supermassive star Eta Carinae. The emission is characterized by a temperat…
Measurement of Cosmic Shear with the Space Telescope Imaging Spectrograph
Jason Rhodes, Alexandre Refregier, Nicholas R. Collins +3
Weak lensing by large-scale structure allows a direct measure of the dark matter distribution. We have used parallel images taken with the Space Telescope Imaging Spectrograph (STI…
Emission Line Galaxies in the STIS Parallel Survey II: Star Formation Density
Harry I. Teplitz, Nicholas R. Collins, Jonathan P. Gardner +2
We present the luminosity function of [OII]-emitting galaxies at a median redshift of z=0.9, as measured in the deep spectroscopic data in the STIS Parallel Survey (SPS). The lumin…
