Detection of a dense group of hyper-compact radio sources in the central parsec of the Galaxy
Jun-Hui Zhao, Mark R. Morris, W. M. Goss
Using the JVLA, we explored the Galactic center (GC) with a resolution of 0.05" at 33.0 and 44.6 GHz. We detected 64 hyper-compact radio sources (HCRs) in the central parsec. The d…
The MACH HI absorption survey I: Physical conditions of cold atomic gas outside of the Galactic plane
Claire E. Murray, Snežana Stanimirović, Carl Heiles +5
Tracing the transition between the diffuse atomic interstellar medium (ISM) and cold, dense gas is crucial for deciphering the star formation cycle in galaxies. Here we present MAC…
A population of compact radio variables and transients in the radio bright zone at the Galactic center observed with the Jansky Very Large Array
Jun-Hui Zhao, Mark R. Morris, W. M. Goss
Using JVLA data obtained from high-resolution observations at 5.5 GHz at multiple epochs in 2014 and 2019, we have detected a population of radio variables and transients in the ra…
A Population of Compact Radio Sources at the Galactic Center
Jun-Hui Zhao, Mark R. Morris, W. M. Goss
The radio bright zone (RBZ) at the Galactic center has been observed with the JVLA in the A, B and C array configurations at 5.5 and 9 GHz. With a procedure for high-dynamic range…
Time-Variable Radio Recombination Line Emission in W49A
C. G. De Pree, D. J. Wilner, L. E. Kristensen +8
We present new Jansky Very Large Array (VLA) images of the central region of the W49A star-forming region at 3.6~cm and at 7~mm at resolutions of 0\farcs15 (1650 au) and 0\farcs04…
A procedure for making high dynamic-range radio images: Deep imaging of the kiloparsec-scale radio structures of a distant blazar, NRAO 530, with JVLA data
Jun-Hui Zhao, Mark R. Morris, W. M. Goss
Using JVLA data of Sgr A* and NRAO 530 (as a calibrator) at 5.5, 9 and 33 GHz, we developed a procedure for the reduction of wideband data. We have demonstrated that, correcting fo…
