Testing and Validation of the Updated Pixel-Based Non-Linearity Calibration File for WFC3/IR
K. Huynh, V. Bajaj, M. Marinelli +3
The WFC3\IR channel has an innate non-linear response to incident photons, which is corrected for in the calwf3 pipeline with the NLINFILE reference file. The 2009 solution is base…
The nuclear cusp slopes of dwarf elliptical galaxies
M. Stiavelli, B. W. Miller, H. C. Ferguson +3
We derive the light profiles for a sample of 25 dwarf elliptical galaxies observed by us with HST/WFPC2 in F555W and F814W. These profiles are fitted with Nuker, R^1/4, exponential…
A standardised platform for translational advances in fluidic soft systems
M. Gepner, J. Mack, A. A. Stokes
Soft machines are poised to deliver significant real-world impact, with soft robotics emerging as a key sub-discipline. This field integrates biological inspiration, materials scie…
New Photometric Calibration of the Wide Field Camera 3 Detectors
A. Calamida, V. Bajaj, J. Mack +6
We present a new photometric calibration of the WFC3-UVIS and WFC3-IR detectors based on observations collected from 2009 to 2020 for four white dwarfs, namely GRW+70~5824, GD~153,…
HST/STIS Spectroscopy of the Lyman-Alpha Emission Line in the Central Dominant Galaxies in A426, A1795, and A2597: Constraints on Clouds in the Intracluster Medium
S. A. Baum, A. Laor, C. P. O'Dea +2
We report on HST/STIS spectra of the Lyman-alpha emission in the central dominant galaxies in three rich clusters of galaxies. We find evidence for a population of clouds in the in…
The Photometric Performance and Calibration of the HST Advanced Camera For Surveys
M. Sirianni, M. J. Jee, N. Benitez +11
We present the photometric calibration of the HST Advanced Camera for Surveys (ACS). We give here an overview of the performance and calibration of the 2 CCD cameras, the Wide Fiel…
