The Curious Case of the "Heartworm" Nebula
W. D. Cotton, F. Camilo, W. Becker +9
The curious Galactic features near G357.20.2 were observed with the MeerKAT radio interferometer array in the UHF and L bands (0.56--1.68 GHz). There are two possibly related fe…
G0.173-0.42: an X-ray and radio magnetized filament near the galactic center
F. Yusef-Zadeh, M. Wardle, C. Heinke +6
The recent detection of an X-ray filament associated with the radio filament G0.173-0.42 adds to four other nonthermal radio filaments with X-ray counterparts, amongst the more tha…
Evidence for a jet and outflow from Sgr A*: a continuum and spectral line study
F. Yusef-Zadeh, M. Royster, M. Wardle +4
We study the environment of Sgr A* using spectral and continuum observations with the ALMA and VLA. Our analysis of sub-arcsecond H30alpha, H39alpha, H52alpha and H56alpha line emi…
ALMA and VLA observations of emission from the environment of Sgr A*
F. Yusef-Zadeh, R. Schödel, M. Wardle +6
We present 44 and 226 GHz observations of the Galactic center within 20 of Sgr A*. Millimeter continuum emission at 226 GHz is detected from eight stars that have previously bee…
An OH(1720 MHz) Maser and a Nonthermal Radio Source in Sgr B2(M): A SNR--Molecular Cloud Interaction Site?
F. Yusef-Zadeh, W. Cotton, M. Wardle +1
Sgr B2 is a well-known star forming molecular cloud complex in the Galactic center region showing evidence of high energy activity as traced by the K neutral FeI line at 6.4 keV…
Rotation Measures in AGN jets seen by VLA at 21 cm to 6 mm
E. V. Kravchenko, W. D. Cotton, Y. Y. Kovalev
We present Faraday Rotation Measure (RM) properties of seven active galactic nuclei (AGN), observed with the NRAO VLA at three epochs in 2012-2014. Data was taken at 1.4, 2.2, 5.0,…
