COSMOS : Hubble Space Telescope Observations
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Here we review the characteristics of the HST imaging with the Advanced Camera for Surveys (ACS) and parallel observations with NICMOS and WFPC2. A square field (1.8⊓⊔) has been imaged with single-orbit ACS I-F814W expos...
متن کاملIntelligent Scheduling of Hubble Space Telescope Observations
This paper describes the S PIKE system, a general framework for scheduling which has been developed by the Space Telescope Science Institute for NASA’s Hubble Space Telescope (HST). Efficient use of astronomical observatories is very important to the scientific community: the demand for research-grade telescopes far exceeds the supply. The need for efficient scheduling is especially keen for sp...
متن کاملHubble Space Telescope Imaging of 11 Carinae
We present new high spatial resolution observations of the material around 11 Carinae obtained with the Hubble Space Telescope Wide Field/Planetary Camera. The star 11 Carinae is one of the most massive and luminous stars in our Galaxy, and has been episodically expelling significant quantities of gas over the last few centuries. The morphology of the bright central nebulosity (the homunculus) ...
متن کاملHubble Space Telescope Imaging of the Schwartz
Schwartz 82 (IM Lupi; HBC 605; IRAS 15528-3747) is an M0 T Tauri star located within the Lupus star forming clouds at a distance of ∼190 pc (Wichmann et al. 1998). It is one of four young stellar objects in a small CO(1-0) core near the extreme T Tauri star RU Lupi (Tachihara et al. 1996). Unlike its more famous neighbor, Sz 82 displays only a modest amount of emission-line activity, with an Hα...
متن کاملModeling technique for the Hubble Space Telescope wave-front deformation.
Images from the Hubble Space Telescope suffer from an overcorrected spherical aberration that is due to a conic-constant error in the primary mirror. Within the program known as the corrective optics space telescope axial replacement (COSTAR) simulators have been built to provide the point-spread function (PSF) of the telescope alone and of the telescope with the faint-object camera F/96. It wa...
