We present an overview of a 90-orbit Hubble Space Telescope treasury program
to obtain near ultraviolet imaging of the Hubble Ultra Deep Field using the
Wide Field Camera 3 UVIS detector with the F225W, F275W, and F336W filters.
This survey is designed to: (i) Investigate the episode of peak star formation
activity in galaxies at 1. Preliminary results on number counts of UV-selected
galaxies and morphology of galaxies at z~1 are presented. We find that the
number density of UV dropouts at redshifts 1.7, 2.1, and 2.7 is largely
consistent with the number predicted by published luminosity functions. We also
confirm that the image mosaics have sufficient sensitivity and resolution to
support the analysis of the evolution of star-forming clumps, reaching 28-29th
magnitude depth at 5 sigma in a 0.2 arcsecond radius aperture depending on
filter and observing epoch.
We perform a morphological study of 124 spectroscopically confirmed cluster
Galaxies in the z=0.84 galaxy cluster RX J0152.7-1357. Our classification
Scheme includes color information, visual morphology, and 1-component and
2-component light profile fitting derived from Hubble Space Telescope riz
We discuss the uncer-
Tainties, by comparing GOES fluxes with the high cadence EUV data from the
Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory
(SDO). We conclude that the EUVI 195 A data can provide estimates of the X-ray
Peak fluxes of intense flares (e.g., above M4 in...
Based on our 5-year results, treatment of progressive keratoconus with CXL can stop disease progression, without raising any concern for safety, and can eliminate the need for keratoplasty.
