A Scattered Light Echo around SN 1993J in M81

A light echo around SN 1993J was observed 8.2 yr after explosion by a Hubble Space Telescope Wide Field Planetary Camera 2 observation, adding to the small family of supernovae with light echoes. The…

Infrared Echoes near the Supernova Remnant Cassiopeia A

Two images of Cassiopeia A obtained at 24 micrometers with the Spitzer Space Telescope over a 1-year time interval show moving structures outside the shell of the supernova remnant to a distance of…

The Dust-scattered X-Ray Halo around Swift GRB 050724

The X-ray halo around the Swift -ray burst GRB 050724 (z 1⁄4 0:258), detected by the Swift X-Ray Telescope, expands to a radius of 20000 within 8 ks of the burst, exactly as expected for small-angle X-rays scattering by Galactic dust along the line of sight to a cosmologically distant GRB.

The Compact Central Object in Cassiopeia A: A Neutron Star with Hot Polar Caps or a Black Hole?

The central pointlike X-ray source of the Cassiopeia A supernova remnant was discovered in the Chandra first light observation and found later in the archival ROSAT and Einstein images. The analysis…

The Cassiopeia A Supernova Was of Type IIb

The spectrum shows that Cassiopeia A was a type IIb supernova and originated from the collapse of the helium core of a red supergiant that had lost most of its hydrogen envelope before exploding.

The massive binary companion star to the progenitor of supernova 1993J

Photometric and spectroscopic observations of SN1993J ten years after the explosion detect the unambiguous signature of a massive star: the binary companion to the progenitor.

A Preliminary Search for Light Echoes from Supernovae

The light echoes from SN1987A

Direct imaging1,2 of supernova 1987A has revealed two semicircular arcs around the explosion site. Similar arcs around Nova Persei3,4 and Nova V732 Sagittarii5 have been explained as light echoes…

Constraints on the Progenitor of Cassiopeia A

We compare a suite of three-dimensional explosion calculations and stellar models incorporating advanced physics with observational constraints on the progenitor of Cassiopeia A. We consider binary…
