We report results from high resolution optical spectroscopy of three non-radiative galactic supernova remnants, RCW 86, Kepler's supernova remnant and SN 1006. We have measured the narrow component Hα line widths in Balmer- dominated filaments in RCW 86 and SN 1006, as well as the narrow component width in a Balmer-dominated knot in Kepler's SNR. The narrow component line widths measured in RCW 86 and Kepler's SNR show FWHM of 30−40 km s −1 , similar to what has been seen in other Balmer…

Subaru HDS Observations of a Balmer-dominated Shock in Tycho’s Supernova Remnant*
We present an Hα spectral observation of a Balmer-dominated shock on the eastern side of Tycho's supernova remnant using the Subaru Telescope. Utilizing the High Dispersion Spectrograph (HDS), we

We present high-resolution long-slit spectroscopy of a Balmer-dominated shock in the northeastern limb of the Cygnus Loop with the Subaru high dispersion spectrograph. By setting the slit angle along
Forbidden Line Emission from Type Ia Supernova Remnants Containing Balmer-dominated Shells
Balmer-dominated shells in supernova remnants (SNRs) are produced by collisionless shocks advancing into a partially neutral medium and are most frequently associated with Type Ia supernovae. We have
Resolved shock structure of the Balmer-dominated filaments in Tycho's supernova remnant: Cosmic-ray precursor?
We report on the results from Hα imaging observations of the eastern limb of Tycho's supernova remnant (SN1572) using the Wide Field Planetary Camera 2 on the Hubble Space Telescope. We resolve the
Proper motions of Hα filaments in the supernova remnant RCW 86
We present a proper motion study of the eastern shock-region of the supernova remnant RCW 86 (MSH 14-63, G315.4−2.3), based on optical observations carried out with Very Large Telescope/FOcal Reducer
RCW 86: A TYPE Ia SUPERNOVA IN A WIND-BLOWN BUBBLE
We report results from a multi-wavelength analysis of the Galactic supernova remnant RCW?86, the proposed remnant of the supernova of 185 A.D. We show new infrared observations from the Spitzer Space
Spitzer Space Telescope Observations of Kepler's Supernova Remnant: A Detailed Look at the Circumstellar Dust Component
We present 3.6-160 ?m infrared images of Kepler's supernova remnant (SN 1604) obtained with the IRAC and MIPS instruments on the Spitzer Space Telescope. We also present MIPS SED low-resolution
A high-resolution ultraviolet absorption spectrum of supernova ejecta in SN1006
We report a high-resolution, far-ultraviolet, Space Telescope Imaging Spectrograph (STIS) E140M spectrum of the strong, broad Si II, III and iv features produced by the ejecta of the supernova of
Using optical lines to study particle acceleration at supernova remnants
The shocks of several young supernova remnants (SNR) are often associated with very thin optical filaments dominated by Balmer emission resulting from charge-exchange and collisional excitation

The optical spectrum of the sn 1006 supernova remnant revisited
We present the deepest optical spectrum acquired to date of Balmer-dominated shocks in the northwest rim of SN 1006. We detect the broad and narrow components of Hα, Hβ, and Hγ and report the first
High-Resolution Spectroscopy of Balmer-dominated Shocks in the Large Magellanic Cloud
We present high-resolution spectra of the four Balmar-dominated supernova remnants (SNRs) in the Large Magellanic Cloud (LMC). These data allow us to measure the width of the narrow component of H
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
High-velocity emission in young supernova remnants: SN 1006 and SN 1572
The paper reports the discovery of broad H-alpha emission from the SN 1006 remnant with a FWHM velocity of 2600 + or - 100 km/s. This emission is similar to that seen in the remnant of SN 1572 which
Evidence for Shock Precursors in Tycho's Supernova Remnant
We report optical spectroscopy and imaging of Tycho's supernova remnant (SNR) which suggest that two different precursors are associated with the blast wave. In long-slit spectra of the eastern rim,
Six Balmer-dominated supernova remnants
Spectra of six Balmer-dominated SNRs are examined: the Galactic SNR of SN 1572 and SN 1006, the LMC SNR 0505-67.9, 0509-67.5, 0519-69.0, and 0548-70.4. A shock velocity is derived for each SNR with
