The youngest Galactic supernova remnant, G1.9+0.3, probably the result of a Type Ia supernova, shows surprising anomalies in the distribution of its ejecta in space and velocity. In particular, high-velocity shocked iron is seen in several locations far from the remnant center, in some cases beyond prominent silicon and sulfur emission. These asymmetries strongly suggest a highly asymmetric explosion. We present high-resolution hydrodynamic simulations in two and three dimensions of the…

Süpernova Kalıntısı G12.8-0.0’nin Suzaku ile X-ışın Dalgaboylarında Araştırılması
The Galactic supernova remnant (SNR) G12.8-0.0 is a member of the class of composite SNRs and hosts the pulsar PSR J1813–1749. In this work, we investigate the X-ray nature of the emission and


A Deep Chandra Observation of Kepler’s Supernova Remnant: A Type Ia Event with Circumstellar Interaction
We present initial results of a 750 ks Chandra observation of the remnant of Kepler's supernova of AD 1604. The strength and prominence of iron emission, together with the absence of O-rich ejecta,
Interaction of Type Ia Supernovae with Their Surroundings
Type Ia supernovae (SNe) are presumed to arise from white dwarf progenitors, which may not appreciably modify their ambient medium. We study the interaction of the resulting supernova remnants with a
Systematic Spatial Variations of the Spectrum of Synchrotron X-rays from the Youngest Galactic Supernova Remnant G1.9+0.3
Our 50 ks Chandra observation of the small radio supernova remnant (SNR) G1.9+0.3 shows a complete shell structure with strong bilateral symmetry, about 100'' in diameter. The radio morphology is
Abundance stratification in type Ia supernovae – IV. The luminous, peculiar SN 1991T
The abundance distribution of the elements in the ejecta of the peculiar, luminous Type Ia supernova (SN Ia) 1991T is obtained modelling spectra from before maximum light until a year after the
Abundance stratification in Type Ia supernovae - I. The case of SN 2002bo
The abundance stratification in the ejecta of the normal Type Ia supernova 2002bo is derived by fitting a series of spectra obtained at close time intervals. A Monte Carlo code, modified to include
Modelling the interaction of thermonuclear supernova remnants with circumstellar structures: the case of Tycho's supernova remnant
The well-established Type Ia remnant of Tycho's supernova (SN 1572) reveals discrepant ambient medium-density estimates based on either the measured dynamics or the X-ray emission properties. This
Three-dimensional numerical investigations of the morphology of Type Ia SNRs
We explore the morphology of Type Ia supernova remnants (SNRs) using threedimensional hydrodynamics modeling and an exponential density profile. Our model distinguishes ejecta from the interstellar
From Supernova to Supernova Remnant: The Three-dimensional Imprint of a Thermonuclear Explosion
Recent progress in the three-dimensional modeling of supernovae (SN) has shown the importance of asymmetries for the explosion. This calls for a reconsideration of the modeling of the subsequent
Nebular spectra and abundance tomography of the Type Ia supernova SN 2011fe: a normal SN Ia with a stable Fe core
A series of optical and one near-infrared nebular spectra covering the first year of the Type Ia supernova SN 2011fe are presented and modelled. The density profile that proved best for the early
The Outermost Ejecta of Type Ia Supernovae
The properties of the highest velocity ejecta of normal Type Ia supernovae (SNe Ia) are studied via models of very early optical spectra of six SNe. At epochs earlier than 1 week before maximum, SNe
