Calibrating Interstellar Abundances using SNR Radiative Shocks
Michael A. Dopita, Ivo R. Seitenzahl, Ralph S. Sutherland +4
Using integral field data we extract the optical spectra of shocked interstellar clouds in Kepler's supernova remnant located in the inner regions of our Galaxy, as well as in the…
SN 2017ens: The Metamorphosis of a Luminous Broad-lined Type Ic Supernova into an SN IIn
T. -W. Chen, C. Inserra, M. Fraser +46
We present observations of supernova (SN) 2017ens, discovered by the ATLAS survey and identified as a hot blue object through the GREAT program. The redshift z=0.1086 implies a pea…
Rigid colourings of hypergraphs and contiguity
Peter Ayre, Catherine Greenhill
We consider the problem of -colouring a -uniform random hypergraph, where , and determine the rigidity threshold. For edge densities above the rigidity threshold,…
Shocked Interstellar clouds and dust grain destruction in the LMC Supernova Remnant N132D
Michael A. Dopita, Frédéric P. A. Vogt, Ralph S. Sutherland +3
From integral field data we extract the optical spectra of 20 shocked clouds in the supernova remnant N132D in the Large Magellanic Cloud (LMC). Using self-consistent shock modelli…
A nearby superluminous supernova with a long pre-maximum 'plateau' and strong CII features
J. P. Anderson, P. J. Pessi, L. Dessart +63
Super-luminous supernovae (SLSNe) are rare events defined as being significantly more luminous than normal terminal stellar explosions. The source of the extra powering needed to a…
Identification of the Central Compact Object in the young supernova remnant 1E0102.2-7219
F. P. A. Vogt, E. S. Bartlett, I. R. Seitenzahl +4
Oxygen-rich young supernova remnants are valuable objects for probing the outcome of nucleosynthetic processes in massive stars, as well as the physics of supernova explosions. Obs…
