X-ray Observations of Two Radio-Selected Transients Near the Galactic Center
Abstract
A blind search program using the VLA at 330 MHz, made possible by new wide-field radio imaging techniques, has resulted in the discovery of two radio-selected transients near the Galactic Center. One of these exhibits dramatic 1 Jy outbursts that last about 10 min and have a recurrance interval of about 77 minutes. The radio emission violates the maximum brightness temperature limit for incoherent synchrotron radiation if D>70 pc, implying that the source is a coherent emitter, and likely a member of a new source class. We propose follow-up Chandra observations to characterize the X-ray emission from these new sources. This will allow us to measure Lx, refine the position (needed for counterpart searches), constrain the distance, and search for X-ray flaring and periodicities.
