We report our discovery of the likely near-infrared counterpart to the anomalous X-ray pulsar (AXP) 1E 1048.1-5937, using observations from the 6.5 m Baade (Magellan I) telescope in Chile. We derived a precise position for the X-ray source using archival data from the Chandra X-Ray Observatory. This position is inconsistent with a position reported earlier from XMM-Newton, but we show that the originally reported XMM-Newton position suffered from attitude reconstruction problems. Only two of…

An optical counterpart to the anomalous X-ray pulsar 4U0142+61
TLDR
Deep optical observations of the field around 4U0142+61, which is the brightest AXP in X-rays, are reported, and an object with peculiar optical colours at the position of the X-ray source is found, and it is argued that it is the optical counterpart.

We report on an observation of the anomalous X–ray pulsar 1E 1048.1–5937 performed with the XMM-Newton satellite. The phase averaged spectrum of 1E 1048.1–5937 is well described by the sum of a power

We present new observations of two anomalous X-ray pulsars (AXPs), 4U 0142+61 and 1E 1048.1-5937, made in 1998 with ASCA. The energy spectrum of each of these two AXPs is found to consist of two
Optical pulsations from the anomalous X-ray pulsar 4U0142+61
TLDR
The pulsed fraction of optical light is five to ten times greater than that of soft X-rays, from which it is concluded that 4U0142+61 is a magnetar, which establishes a direct relationship between AXPs and the soft γ-ray repeaters, the evolutionary connection betweenAXPs, SGRs and radio pulsars remains controversial.

Magnetar-like X-ray bursts from an anomalous X-ray pulsar
TLDR
Two X-ray bursts, with properties similar to those of SGRs, from the direction of the anomalousX-ray pulsar 1E1048.1 - 5937.1 imply a close relationship (perhaps evolutionary) between AXPs and S GRs, with both being magnetars.
