Chandra and Suzaku observations of two galactic TeV sources
Abstract
We present preliminary results from Chandra and Suzaku observations of the TeV sources HESS J1809-193 and HESS J1741-302A. Multi-wavelength observations of the HESS J1809-193 field reveal a complex picture. Although most of the bright TeV emission can be attributed to the pulsar-wind nebula of PSR J1809-1917, several supernova remnants, as well as another PWN, may contribute to the observed VHE emission. The H.E.S.S. image shows an extension toward north-east, which could be a separate TeV source. One of the X-ray sources in the north-east extension of HESS J1809-193 is the low-mass X-ray binary candidate XTE J1810-189, for which we show the outburst history from multiple observatories. We also present analysis of the Fermi LAT data for both H.E.S.S. sources. Preliminary multi-wavelength classification is presented for the brightest X-ray sources in the fields of the two TeV sources. We investigate whether there is any correlation between the TeV emission and the sources seen at lower energies. This research was partially supported by NASA grants NNX10AH82G, NNX09AC81G, and NASA/SAO grant GO3-14049X.
