About 200 supernova remnants have been found in the galaxy, six of which are younger than about 1,000 years (ref. 2). Observations of these young remnants are important for understanding of the late phases of supernova evolution, and each new object should add substantially to our knowledge of the processes involved. Here I report the discovery of a supernova remnant (RXJ0852.0 − 4622), identified by its X-ray emission, at the southeast corner of the known Vela supernova remnant. The high… 

The Progenitor of the New COMPTEL/ROSAT Supernova Remnant in Vela

We show that (1) the newly discovered supernova remnant (SNR) GRO J0852-4642/RX J0852.0-4622 was created by a core-collapse supernova of a massive star and (2) the same supernova event that produced

The Slow X-Ray Expansion of the Northwestern Rim of the Supernova Remnant RX J0852.0–4622

The detection of the radioactive decay line of 44Ti provides unique evidence that the γ-ray source is a young (<1000 yr) supernova remnant because of the short 44Ti lifetime of ~90 yr. Only two

Discovery of 35 New Supernova Remnants in the Inner Galaxy

We report the discovery of up to 35 new supernova remnants (SNRs) from a 42'' resolution, 90 cm multiconfiguration Very Large Array survey of the Galactic plane covering 4.°5 < l < 22.°0 and ∣b∣ <

Radio Detection of the Supernova Remnant RX J0852.0–4622

The X-ray source RX J0852.0-4622 has been recently proposed as a candidate for a young nearby supernova remnant on the basis of its X-ray (≥1.3 keV) morphology, inferred internal shock velocities,

An Optical Nebula Associated with a Young X-Ray Supernova Remnant in Vela

A remarkable filamentary nebula (RCW 37) in the close vicinity of the newly discovered X-ray-emitting supernova remnant in Vela (RX J0852.0-4622) is investigated. This supernova explosion is arguably

Hoinga: a supernova remnant discovered in the SRG/eROSITA All-Sky Survey eRASS1

Supernova remnants (SNRs) are observable for about (6−15) × 104 yr before they fade into the Galactic interstellar medium. With a Galactic supernova rate of approximately two per century, we can

Chandra Observations of Galactic Supernova Remnant Vela Jr.: A New Sample of Thin Filaments Emitting Synchrotron X-Rays

The Galactic supernova remnant (SNR) Vela Jr. (RX J0852.0-4622, G266.6-1.2) shows sharp filamentary structures on its northwestern edge in the hard X-ray band. The filaments are very smooth and

The Vela supernova remnant and the Gum nebula: new perspectives at 2.4 GHz

Sensitive, polarimetric observations are presented for the region of the Galactic plane 276°~1~238°, with a latitude coverage of +5°~b~ _80 over most of this range. These observations were made using

Radio Emission from the Supernova Remnant Vela-X

Radio observations are presented of the fairly large galactic complex Vela-X, Y, and Z. These sources are believed to be the remnant of a supernova having an optical identification with the

ROSAT PSPC observations of the remnant of SN 1006

We report soft X-ray observations (- 0.1-2.4 keY) of the remnant of the AD 1006 supernova, obtained with the ROSAT PSPC in 1993 January. These data provide the best spectrally resolved X-ray images

Discovery of explosion fragments outside the Vela supernova remnant shock-wave boundary

THE nearby (500 pc) Vela supernova remnant has presented several puzzles. Its true shape has been difficult to determine1, and as a result it has never been clear whether the pulsar seen in that part
