Pulsar Near the Supernova Remnant RCW 103

Received ; accepted – 2 – ABSTRACT We report the detection of the radio pulsar counterpart to the 69 ms X-ray pulsar discovered near the supernova remnant RCW 103 (G332.4−0.4). Our detection confirms that the pulsations arise from a rotation-powered neutron star, which we name PSR J1617−5055. The observed barycentric period derivative confirms that the pulsar has a characteristic age of only 8 ...

An unresolved X - ray source inside the supernova remnant RCW 86

We report on the discovery of an unresolved X-ray source inside the supernova remnant G315.4-2.3 (RCW 86). The source is located 7 to the Southwest of the geometrical centre and may be close to the actual explosion centre of the supernova, which makes this a candidate for the stellar remnant associated with RCW 86. However, the presence of a possible optical counterpart with V ∼ 14 at 3 from th...

Iron-rich Ejecta in the Supernova Remnant Dem L71

Chandra X-ray observations of DEM L71, a supernova remnant (SNR) in the Large Magellanic Cloud (LMC), reveal a clear double shock morphology consisting of an outer blast wave shock surrounding a central bright region of reverse-shock heated ejecta. The abundances of the outer shock are consistent with LMC values, while the ejecta region shows enhanced abundances of Si, Fe, and other species. Ho...

Dense Iron Ejecta and Core - collapse Supernova Explosion in the Young Supernova Remnant

We present the results of near-infrared spectroscopic observations of dense ( > ∼ 10 3 cm) iron ejecta in the young core-collapse supernova remnant G11.2– 0.3. Five ejecta knots projected to be close to its center show a large dispersion in their Doppler shifts: two knots in the east are blueshifted by more than 1,000 km s, while three western knots have relatively small blueshifts of 20–60 km ...

Balmer-Dominated Spectra of Nonradiative Shocks in the Cygnus Loop, RCW 86 and Tycho Supernova Remnants

We present an observational and theoretical study of the optical emission from nonradiative shocks in three supernova remnants: the Cygnus Loop, RCW 86 and Tycho. The spectra of these shocks are dominated by collisionally excited hydrogen Balmer lines which have both a broad component caused by proton-neutral charge exchange and a narrow component caused by excitation of cold neutrals entering ...
