We present X-ray images of Tycho's supernova remnant in emission-line features of Mg, Si, S, Ar, Ca, and Fe, plus the continuum, using data obtained by the imaging spectrometers on board the Advanced Satellite for Cosmology and Astrophysics (ASCA). All the images show the shell-like morphology characteristic of previously obtained broadband X-ray images, but they are clearly distinct from each other. We use image reconstruction techniques to achieve a spatial resolution of ~0.′8. Line intensity… 

The X-Ray Iron Emission from Tycho's Supernova Remnant

We present the results of broadband spectral model fits to the X-ray spectrum of Tycho's supernova remnant obtained by the Solid-State Imaging Spectrometers on the ASCA Observatory. We use single

Mapping the X-Ray-Emitting Ejecta in Cassiopeia A with Chandra

We present X-ray emission-line equivalent width images of the bright Galactic supernova remnant Cassiopeia A for the elements Si, S, Ar, Ca, and Fe using a 50,000 s observation with the Advanced CCD

Thermal and Nonthermal X-Ray Emission from the Forward Shock in Tycho’s Supernova Remnant

We present Chandra X-ray images of Tycho's supernova remnant that delineate its outer shock as a thin, smooth rim along the straight northeastern edge and most of the circular western half. The

High spatial resolution spectroscopy of Tycho’s SNR with Chandra

We present high spatial resolution X-ray spectroscopy of Tycho’s supernova remnant (SNR) using observational data from Chandra. The whole remnant was divided into 26 × 27 regions, with each of them

Thermal X‐Ray Emission from Young Type Ia Supernova Remnants

In the years since the launch of Chandra and XMM-Newton, the increase in the quantity and quality of X-ray observations of supernova remnants (SNRs) has been spectacular. In many of the brightest

Suzaku Observations of Tycho's Supernova Remnant

Tycho's supernova remnant was observed by the XIS and HXD instruments onboard the Suzaku satellite on 2006 June 26-29 for 92 ks. The spectrum up to 30 keV was well fitted with a two-component model,


We show that the expansion of ejecta in Tycho's supernova remnant (SNR) is consistent with a spherically symmetric shell, based on Suzaku measurements of the Doppler broadened X-ray emission lines.

X-Ray Emission from a Supernova Remnant, G344.7-0.1, Observed in the ASCA Galactic Plane Survey

X-ray emission from a cataloged radio supernova remnant (SNR), G344.7−0.1, was observed in the ASCA Galactic Plane Survey. The X-ray image showed extended emission with a diameter of 6 � –8 � . The


We present X-ray proper-motion measurements of the forward shock and reverse-shocked ejecta in Tycho's supernova remnant, based on three sets of archival Chandra data taken in 2000, 2003, and 2007.

The imaging and spectral capabilities of the Chandra X–ray Observatory and XMM–Newton are extremely well suited for studying the remnants of supernovae, particularly for imaging spectroscopy, which can probe the progressive ionization at the shock fronts, the elemental distribution in the ejecta, and Doppler imaging.



Evidence for Elemental Variation in the Ejecta of the TYCHO Supernova Remnant

We present an X-ray study of the Tycho supernova remnant utilizing archival data from the high-resolution imagers (HRIs) on Einstein and ROSAT, the low-energy imaging telescopes (LEITs) on EXOSAT,

An X-ray image of Tycho's supernova remnant

An image of Tycho's SNR has been obtained using the imaging proportional counter aboard the Einstein Observatory, revealing a nearly circular, 8 arcmin, open shell of emission. The X-ray and radio

The mass of Tycho's supernova remnant as determined from a high-resolution X-ray map.

High resolution Einstein Observatory X ray images of Tycho's supernova remnant (SNR) are discussed. The object has features of a shock heated shell in the interstellar medium, accompanied by an inner

Self-consistent models for the X-ray emission from supernova remnants

A tool for exploring the evolution of X-ray emission from young SNRs is presented which employs a novel approach to the problem of time-dependent ionization in a shock-heated plasma. The solution of

X-ray line emission from the Puppis A supernova remnant - Oxygen lines

Six prominent X-ray emission lines of O VII and O VIII have been detected from a portion of the Puppis A supernova remnant in observations with the Einstein Observatory Focal Plane Crystal

The x-ray spectra of the Vela and Puppis supernova remnants and the shock- wave model of supernova remnants

The structure and spectrum of the Vela and Puppis supernova remnants (SNRs) were observed in soft (0.1 to 1.5 keV) X rays from a rocket. The spectral data of both objects below 1.5 keV are consistent

The X-ray spectrum of TYCHO

Baade (1945) has identified Tycho's supernova (SN) of A.D. 1572 as Type I, taking into account an analysis of the light curve recorded by Tycho. However, in spite of the obvious interest of Tycho's

Elemental abundances in a Type I supernova remnant

The solid-state spectrometer (SSS) on the HEAO 2 (Einstein) X-ray observatory observed the X-ray spectrum of Tycho's SNR. The observations show a relative excess of line emission from Si, S, and Ar

X-Ray Spectroscopy of Young Supernova Remnants: Mixing in the Ejecta of Type I and II Supernovae

Supernova remnants (SNRs) are the product of stellar explosions. From them we can learn much about the late stages of stellar evolution, mass-loss processes in stars, and explosive nucleosynthesis.

Radio structure of the remnant of Tycho's supernova (SN 1572)

The radio emission from the remnant of Tycho's supernova of 1572 arises in a nearly circular, clumpy shell. A very distinct, thin bright rim just outside the main shell can be seen around most of the
