A Pulsar Survey of 18 Supernova Remnants [PDF]
, 1996 We have performed a pulsar search of 18 known or probable supernova remnants with the Arecibo 305 m radio telescope at 430 and 1420 MHz. The remnants were selected to have angular sizes less than or of order a few telescope beam diameters (˜10' at 430 ...

The Astrophysical JournalWe systematically study how cooling creates structural changes in supernova remnants as they evolve. Inspired by the peculiar morphology of the Pa 30 nebula, we adopt a framework in which to characterize supernova remnants under different degrees of ...

Excited-State OH Masers and Supernova Remnants
, 2008 The collisionally pumped, ground-state 1720 MHz maser line of OH is widely recognized as a tracer for shocked regions and observed in star-forming regions and supernova remnants.

Mapping the Dense Molecular Gas toward 13 Supernova Remnants
The Astrophysical JournalSupernova remnants (SNRs) can exert strong influence on molecular clouds (MCs) through interaction by shock wave and cosmic rays. In this paper, we present our mapping observation of HCO ^+ and $\mathrm{HCN}$ 1–0 lines toward 13 SNRs interacting with MCs,

X-ray Polarimetry of Supernova Remnants
, 2021 Young supernova remnants such as Tycho, Cas A and SN1006 are relativistic particle accelerators and likely the sources of Galactic cosmic rays. In these sources X-ray synchrotron emitting regions, such as the shock fronts, have been identified and their ...

Historical Supernovae and Supernova Remnants [PDF]
International 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.

Topics in Core-Collapse Supernova Theory: The Formation of Black Holes and the Transport of Neutrinos [PDF]
, 2012 Core-Collapse Supernovae are one of the most complex astrophysical systems in the universe. They deeply entwine aspects of physics and astrophysics that are rarely side by side in nature.

Nonthermal Signatures of Radiative Supernova Remnants
The Astrophysical JournalThe end of supernova remnant (SNR) evolution is characterized by a so-called “radiative” stage, in which efficient cooling of the hot bubble inside the forward shock slows expansion, leading to eventual shock breakup.

Gammaray emission of supernova remnants
, 2011 History of gamma ray astronomy is shortly reviewed. Information on the observations of supernova remnants in gamma- rays as well as on the studies of Ukrainian scientists in this field is presented.

Searching for runaway OB stars in Supernova remnants
, 2005 Searching for runaway stars in Supernova remnants gives us the possibility to estimate the mass ratio in binary systems in which there occur Supernova explosion.
