A variable infrared counterpart to the soft gamma-ray repeater Sgr 1806-20.


Abstract (from CDS):

We present K'-band (2.12 µm) imaging observations of the SGR 1806-20 field taken during its very active phase in mid-2004; these observations 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 to SGR 1806-20. The other two sources are located in close proximity to the probable counterpart and show marginal brightening, which may suggest that the high-energy photons emitted from the soft gamma-ray repeater (SGR) during its active phase have induced dust sublimation or brightening of the unresolved background around the SGR.
