Dale A. Frail, Scott D. Hyman, Michele L. Silverstein +10
We report on an unusual radio source J180526-292953, initially identified as a steep spectrum, polarized point source toward the Galactic bulge and found to coincide with the nearb…
VLA+VLBA to ngVLA Transition Option Concepts
Alessandra Corsi, Joseph W. Lazio, Stefi Baum +17
The next-generation Very Large Array (ngVLA) is intended to be the premier centimeter-wavelength facility for astronomy and astrophysics, building on the substantial scientific leg…
