DETECTION OF SAGITTARIUS A* AT 330 MHz WITH THE VERY LARGE ARRAY
نویسندگان
چکیده
We report the detection of Sgr A*, the radio source associated with our Galaxy’s central massive black hole, at 330 MHz with the Very Large Array. Implications for the spectrum and emission processes of Sgr A* are discussed and several hypothetical geometries of the central region are considered. Subject headings: Galaxy: center — Galaxy: nucleus

We present a wide field, sub-arcminute resolution VLA image of the Galactic Center region at 330 MHz. With a resolution of ∼ 7 × 12 and an RMS noise of 1.6 mJy beam, this image represents a significant increase in resolution and sensitivity over the previously published VLA image at this frequency. The improved sensitivity has more than tripled the census of small diameter sources in the region...
متن کاملCircularly Polarized Circular Slot Antenna Array Using Sequentially Rotated Feed Network
This paper presents the design, simulation, and measurement of two low-cost broadband circularly polarized (CP) printed antennas: a single element and an array at C band. The proposed single element antenna is excited by an L-shaped strip with a tapered end, located along the circular-slot diagonal line in the back plane. From the array experimental results, the 3 dB axial ratio bandwidth can r...
متن کاملAnalytical Study of Optical Bi-Stability of a Single-Bus Resonator Based on InGaAs Micro-Ring Array
In this paper, for the first time to our knowledge, we investigate the optical bi-stability in a compact parallel array of micro- ring resonators with 5μm radius, induced by optical nonlinearity. Due to the nature of perfect light confinement, resonance and accumulation process in a ring resonator, optical nonlinear effects, even at small optical power of a few milliwatts in this structure are ...
متن کاملHydra a at Low Radio Frequencies
We present new, low-frequency images of the powerful FR I radio galaxy Hydra A (3C 218). Images were made with the Very Large Array at frequencies of 1415, 330, and 74 MHz, with resolutions on the order of 2000. The morphology of the source is seen to be more complex and even larger than previously known and extends nearly 80 (530 kpc) in a north-south direction. The southern lobe is bent to th...
