Precise Chandra Localization of the Soft Gamma - ray Repeater SGR 1806 − 20

چکیده
We present observations of the Soft γ-ray Repeater SGR 1806−20 taken with the Chandra X-ray Observatory. We identify the X-ray counterpart of SGR 1806−20 based on detection of 7.5-s pulsations. Using three unrelated X-ray sources (and USNO stars) as position references, we are able to determine that the SGR is at α2000 = 18 0839. 32 and δ2000 = −2

متن کاملPrecise Localization of the Soft Gamma Repeater SGR 1627−41 and the Anomalous X-ray Pulsar AXP 1E1841−045 with Chandra
We present precise localizations of AXP 1E1841−045 and SGR 1627−41 with Chandra. We obtained new infrared observations of SGR 1627−41 and reanalyzed archival observations of AXP 1E1841−045 in order to refine their positions and search for infrared counterparts. A faint source is detected inside the error circle of AXP 1E1841−045. In the case of SGR 1627−41, several sources are located within th...
متن کاملRadio Monitoring and High Resolution Imaging of the Soft Gamma Ray Repeater 1806−20
We report the results of radio flux-monitoring and high resolution observations at 3.6 cm with the VLA, of the central condensation in G 10.0−0.3, the radio nebula surrounding the soft gamma ray repeater (SGR) 1806−20. The quiescent X–ray source AX 1805.7−2025 is coincident with the radio core suggesting that G 10.0−0.3 is a plerionic supernova remnant. The monitoring experiment was performed i...
متن کاملINTEGRAL discovery of persistent hard X - ray emission from the Soft Gamma Ray Repeater SGR 1806 – 20 ⋆
We report the discovery of persistent hard X-ray emission extending up to 150 keV from the soft gamma-ray repeater SGR 1806–20 using data obtained with the INTEGRAL satellite in 2003-2004. Previous observations of hard X-rays from objects of this class were limited to short duration bursts and rare transient episodes of strongly enhanced luminosity (“flares”). The emission observed with the IBI...

We present K -band (2.12 μm) imaging observations of the SGR 1806–20 field taken during its very active phase in mid 2004, which reveal brightening of sources within the Chandra X-ray error circle when compared with earlier images obtained in 2002. One source brightened by more than a factor of 2, and so we consider this to be the probable infrared counterpart for SGR 1806–20. The other two sou...
