SUPERNOVA REMNANT W49B AND ITS ENVIRONMENT [PDF]
, 2014 We study gamma-ray supernova remnant (SNR) W49B and its environment using recent radio and infrared data. Spitzer Infrared Spectrograph low resolution data of W49B shows shocked excitation lines of H2 (0,0) S(0)–S(7) from the SNR–molecular cloud ...

FERMI LARGE AREA TELESCOPE DETECTION OF SUPERNOVA REMNANT RCW 86 [PDF]
, 2014 Using 5.4 yr Fermi Large Area Telescope data, we report the detection of GeV γ-ray emission from the shell-type supernova remnant RCW 86 (G315.4-2.3) with a significance of ∼5.1σ.

Phosphorus in the Young Supernova Remnant Cassiopeia A [PDF]
Science, 2013 We Are Stardust Most of the universe's chemical elements were produced in stars, with the heaviest elements being produced when stars explode. Barlow et al. (p. 1343) used the Herschel Space Observatory to obtain submillimeter spectra of the Crab Nebula,

Gamma-ray emission from young supernova remnants: Hadronic or leptonic?
EPJ Web of Conferences, 2016 The debate on the nature of the gamma-ray emission from young supernova remnants is still open. Ascribing such emission to hadronic rather than leptonic processes would provide an evidence for the acceleration of protons and nuclei, and this fact would ...

On the nature of Tycho Brahe’s supernova
Frontiers in Astronomy and Space Sciences, 2023 At the 450 years anniversary of its observation, the supernova named after Tycho Brahe, SN 1572, can be explained in the terms used nowadays to characterize Type Ia supernovae (SNe Ia).

The First VLBI Image of the Young, Oxygen-Rich Supernova Remnant in NGC 4449 [PDF]
, 2010 We report on sensitive 1.4-GHz VLBI radio observations of the unusually luminous supernova remnant SNR 4449-1 in the galaxy NGC 4449, which gave us the first well-resolved image of this object. The remnant's radio morphology consists of two approximately

THE YOUNGEST KNOWN X-RAY BINARY: CIRCINUS X-1 AND ITS NATAL SUPERNOVA REMNANT [PDF]
, 2013 Because supernova remnants are short-lived, studies of neutron star X-ray binaries within supernova remnants probe the earliest stages in the life of accreting neutron stars.

Multifrequency radio observations of SNR J0536-6735 (N 59B) with associated pulsar [PDF]
Serbian Astronomical Journal, 2012 We present a study of new Australian Telescope Compact Array (ATCA) observations of supernova remnant, SNR J0536-6735. This remnant appears to follow a shell morphology with a diameter of D=36x29 pc (with 1 pc uncertainty in each direction ...

AZIMUTHAL DENSITY VARIATIONS AROUND THE RIM OF TYCHO's SUPERNOVA REMNANT [PDF]
, 2013 Spitzer images of Tycho's supernova remnant in the mid-infrared reveal limb-brightened emission from the entire periphery of the shell and faint filamentary structures in the interior.
