A 16 Millisecond X-ray Pulsar in the Crab-like Snr N157b: Fast times at 30 Doradus
The supernova remnant N157B (30 Dor B, SNR 0539-69.1, NGC 2060), located in the Tarantula Nebula of the Large Magellanic Cloud, has long been considered a possible Crab-like remnant. This hypothesis has been confirmed, quite spectacularly, with the discovery of PSR J0537−6910, the remarkable 16 ms X-ray pulsar in N157B. PSR J0537−6910 is the most rapidly spinning pulsar found to be associated w...
متن کاملChandra Acis Spectroscopy of N157b — a Young Composite Supernova Remnant in a Superbubble
We present a Chandra ACIS observations of N157B, a young supernova remnant (SNR) located in the 30 Doradus star-formation region of the Large Magellanic Cloud. This remnant contains the most energetic pulsar known (J053747.39–691020.2; Ė = 4.8 × 10 ergs s), which is surrounded by a X-ray bright nonthermal nebula that likely represents a toroidal pulsar wind terminal shock observed edge-on. Two ...
متن کاملDiscovery of a New Pulsar Wind Nebula in the Large Magellanic Cloud
We present new high-resolution radio and X-ray observations of the supernova remnant (SNR) B0453–685 in the Large Magellanic Cloud, carried out with the Australia Telescope Compact Array and the Chandra X-ray Observatory respectively. Embedded in the SNR shell is a compact central nebula producing both flat-spectrum polarized radio emission and non-thermal X-rays; we identify this source as a p...
متن کاملHRI Detection of the 16 ms Pulsar PSR J 0537 - 6910 Inside SNR N 157 B
Based on a deep ROSAT HRI observation, we have detected a pulsed signal in the 0.1-2 keV band from PSRJ0537-6910 — the recently discovered pulsar associated with the supernova remnant N157B in the Large Magellanic Cloud. The measured pulse period 0.01611548182 ms ± 0.02(ns), Epoch MJD 50540.5, gives a revised linear spindown rate of 5.1271×10 s s, slightly greater than the previously derived va...
متن کاملDiscovery of an Ultra-fast X-ray Pulsar in the Supernova Remnant N157B
We present the serendipitous discovery of 16 ms pulsed X-ray emission from the Crab-like supernova remnant N157B in the Large Magellanic Cloud. This is the fastest spinning pulsar associated with a supernova remnant (SNR). Observations with the Rossi X-ray Timing Explorer (RXTE), centered on the field containing SN1987A, reveal an X-ray pulsar with a narrow pulse profile. Archival ASCA X-ray da...
