High Dynamic-Range Radio-Interferometric Images at 327 MHz
Juan M. Uson, William D. Cotton
Radio astronomical imaging using aperture synthesis telescopes requires deconvolution of the point spread function as well as calibration of the instrumental characteristics (prima…
A new z=0 metagalactic UV background limit
Joshua J. Adams, Juan M. Uson, Gary J. Hill +1
We present new integral-field spectroscopy in the outskirts of two nearby, edge-on, late-type galaxies to search for the H-alpha emission that is expected from the exposure of thei…
Pixelization and Dynamic Range in Radio Interferometry
W. D. Cotton, Juan M. Uson
This study investigates some of the consequences of representing the sky by a rectangular grid of pixels on the dynamic range of images derived from radio interferometric measureme…
Corrugations in the Disk of the Edge-On Spiral Galaxy IC2233
L. D. Matthews, Juan M. Uson
We recently reported the discovery of a regular corrugation pattern in the HI disk of the isolated, edge-on spiral galaxy IC2233. Here we present measurements of the vertical struc…
Beam squint and Stokes V with off-axis feeds
Juan M. Uson, W. D. Cotton
Radio telescopes with off-axis feeds, such as the (E)VLA, suffer from "beam squint" in which the two orthogonal circular polarizations sampled have different pointing centers on th…
Correcting direction-dependent gains in the deconvolution of radio interferometric images
S. Bhatnagar, T. J. Cornwell, K. Golap +1
Astronomical imaging using aperture synthesis telescopes requires deconvolution of the point spread function as well as calibration of instrumental and atmospheric effects. In gene…
