Statistical Properties of the Population of the Galactic Center Filaments II: The Spacing Between Filaments
F. Yusef-Zadeh, R. G. Arendt, M. Wardle +4
We carry out a population study of magnetized radio filaments in the Galactic center using MeerKAT data by focusing on the spacing between the filaments that are grouped. The morph…
Multi-wavelength Observations of Sgr A*. I. 2019 July 18
Joseph M. Michail, Mark Wardle, Farhad Yusef-Zadeh +1
We present and analyze ALMA submillimeter observations from a multi-wavelength campaign of Sgr A* during 18 July 2019. In addition to the submillimeter, we utilize concurrent mid-I…
Detection of a 20 minute time lag observed from Sgr A* between 8 and 10 GHz with the VLA
Joseph M. Michail, Farhad Yusef-Zadeh, Mark Wardle
We report the detection and analysis of a radio flare observed on 17 April 2014 from Sgr A* at GHz using the VLA in its A-array configuration. This is the first reported simult…
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…
Chandra Spectral and Timing Analysis of Sgr A*'s Brightest X-ray Flares
Daryl Haggard, Melania Nynka, Brayden Mon +17
We analyze the two brightest Chandra X-ray flares detected from Sagittarius A*, with peak luminosities more than 600 x and 245 x greater than the quiescent X-ray emission. The brig…
