Outline HESS unID object: HESSJ1614-518 Suzaku observation of HESSJ1614-518 Discovery of an extended X-ray counterpart Other two X-ray objects Discovery of extended soft X-ray emission Discussion Summary Dec. 12, 2007 Suzaku 2007

TeVγ-ray object: HESSJ1614-518 Discovered by the Galactic plane survey with the H.E.S.S. telescope. (Aharonian et al. 2005,2006) Brightest object: F(1-10TeV)=1.8e-11 erg/s/cm2 Dec. 12, 2007 Suzaku 2007

Suzaku Observation (b) TeV image and XIS FOV offset 2006/9/15 45ks (l) Normal mode without the speced-row charge injection Dec. 12, 2007 Suzaku 2007

XIS image (FI CCD) srcA srcC srcB 0.4-3keV 3-10keV Discovery of three X-ray objects srcA, srcB: extended, srcC: point like Dec. 12, 2007 Suzaku 2007

Comparison with the HESS image TeV image 3-10keV srcA 0.4-3keV srcB srcC Src A is spatially coincident with the TeV gamma-ray. Dec. 12, 2007 Suzaku 2007

(The offset observation is not used as a background. Explain later.) Spectral Analysis Definition of spectral regions and a background. 0.4-3keV 3-10keV bgd srcA srcB srcC (The offset observation is not used as a background. Explain later.) Dec. 12, 2007 Suzaku 2007

Spectrum of src A 3-10keV Red:BI Black:FI Featureless = non-thermal Γ=1.73+/-0.33 NH=1.21+/-0.5e22 cm-2 F(2-10keV)=5.3e-13 erg/cm2/s Dec. 12, 2007 Suzaku 2007

Src A is a plausible counterpart to HESSJ1614 Discussion: Src A Src A is a plausible counterpart to HESSJ1614 H.E.S.S. Suzaku srcA B=10μG B=1μG B=0.1μG F(1-10TeV)/F(2-10keV)=34 One of the largest ratios. Other Suzaku results HESSJ1616-508: >55 (Matsumoto et al. 2007) HESSJ1804-216:  25 (Bamba et al. 2007) If the origin of the TeV emission is the inverse Compton of the CMB by high-energy electrons, the magnetic field must be too small. Dec. 12, 2007 Suzaku 2007

Discussion: src A No counterpart in other wavelengths. NH  1.2e22 cm-2 D  10 kpc (c.f. NH (HI survey)  2e22 cm-2) Lx(2-10keV)  6e33 erg/s photon index = 1.7 Harder than the canonical SNR values (2.5-3.0) Non-thermal brems. emission from loss-flattened electron distribution? (e.g., γCygni; Uchiyama et al. 2002) Old SNR? (Yamazaki et al. 2006) PWN? Dec. 12, 2007 Suzaku 2007

Spectrum of srcB Featureless = Non-thermal? Extremely soft! 0.4-3keV Red:BI Black:FI Γ=3.60+/-0.23 NH=1.24+/-0.1e22 cm-2 F(2-10keV)=3.6e-13 erg/cm2/s Dec. 12, 2007 Suzaku 2007

Discussion: src B Spatially coincident with 2MASS J16140610-5152264 The origin of the object is not clarified. Previously detected with Swift XRT in March 2006: variable? F(2-10keV): Swift 1.4e-13 erg/s/cm2 (Landi et al. 2007) Suzaku 3.6e-13 erg/s/cm2 (large err.) Extremely large photon index (3.6) NH  1.2e22 cm-2 Same as that of src A. Physically related to HESSJ1614? Src A= offset PWN and src B = pulsar? (e.g. PSRJ1809-1917 associated with HESSJ1809-193 has a large photon index of 3.2+/-0.4; Kargaltsev & Pavlov 2007) Dec. 12, 2007 Suzaku 2007

Spectrum of src C Red:BI 0.4-3keV Black:FI Thermal spectrum kT=0.63+/-0.1keV Abundance=0.18+/-0.5 solar NH=0.28+/-0.2e22 cm-2 F(2-10keV)=7.6e-15 erg/cm2/s Probably the foreground B9V star HD145703 Dec. 12, 2007 Suzaku 2007

Diffuse soft X-ray emission TeV image BI spectrum Blank-Offset Red:BI Black:FI Γ=2.4 or kT=2.7keV NH=0.1e22cm-2 Offset region. No X-ray and gamma-ray objects. Blank region as a background NHforeground　emission? Not related to HESSJ1614? Dec. 12, 2007 Suzaku 2007

Summary Discovery of three X-ray objects. Src A Extended and spatially coincident with HESSJ1614. Plausible counterpart to HESSJ1614. F(1-10TeV)/F(2-10keV) = 34 It is difficult to explain the ratio in terms of high-energy electrons. Photon index = 1.7 Different from the SNR values. Src B Column density suggests that src B may also be physically related to HESSJ1614. Pulsar? Src C … foreground star Discovery of the extended soft X-ray emission. Dec. 12, 2007 Suzaku 2007
