Probing X-ray Absorption and Optical Extinction in the Interstellar Medium Using Chandra Observations of Supernova Remnants

open access: yes, 2016
We present a comprehensive study of interstellar X-ray extinction using the extensive Chandra supernova remnant archive and use our results to refine the empirical relation between the hydrogen column density and optical extinction.

G7.7-3.7: a young supernova remnant probably associated with the guest star in 386 CE (SN 386)

open access: yes, 2018
Although the Galactic supernova rate is about 2 per century, only few supernova remnants are associated with historical records. There are a few ancient Chinese records of "guest stars" that are probably sightings of supernovae for which the associated ...

Historical Supernovae and Supernova Remnants [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
The oldest historical supernova (SN), recorded by ancient Chinese in 14th Century B.C. on pieces of tortoise shells or bones, is identified with the aid of modern space γ-ray observations. Hard X-rays with energy up to 20 keV were observed from IC 443 by the X-ray satellite Ginga. We infer from these observations the age of IC 443 is ∼ 1000 — 1400 yrs.

Towards an explanation for the 30 Dor (LMC) Honeycomb nebula - the impact of recent observations and spectral analysis

open access: yes, 2010
The unique Honeycomb nebula, most likely a peculiar supernova remnant, lies in 30 Doradus in the Large Magellanic Cloud. Due to its proximity to SN1987A, it has been serendipitously and intentionally observed at many wavelengths.

Supernova Remnants and their Supernovae [PDF]

open access: yesInternational Astronomical Union Colloquium, 1988
AbstractObserving supernova remnants provides important clues to the nature of supernova explosions. Conversely, the late stages of stellar evolution and the mechanism of supernova explosions affect supernova remnants through circumstellar matter, stellar remnants, and nucleosynthesis. The elements of supernova classification and the connection between

The Distance to the S147 Supernova Remnant

open access: yesThe Astrophysical Journal
In the absence of a parallax distance to a pulsar or a surviving binary in a supernova remnant (SNR), distances to Galactic SNRs are generally very uncertain.

Ionisation loss and shock excitation of 4420Са I and 4420Са II atoms in cold remnants of type II supernovae

open access: yesOdessa Astronomical Publications, 2017
The light emission (“glow”) of cold dusty plasma of the remnant of SN 1987A was confirmed by the Hubble Space Telescope observations on 7th January,  1995.
