The impact of supernova remnants on the ISM in Starburst galaxies [PDF]
Proceedings of the International Astronomical Union, 2004 We used the near-infrared [Fe II] emission line signature of shock-heating to detect supernova remnants (SNRs) in nearby starburst galaxies. The near-IR narrow-band imaging program has led to the detection of SNR candidates in NGC 1569 and NGC 5253, both host to super-star clusters.

Inferring properties of the ISM from supernova remnant size distributions [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We model the size distribution of supernova remnants to infer the surrounding ISM density. Using simple, yet standard SNR evolution models, we find that the distribution of ambient densities is remarkably narrow; either the standard assumptions about SNR evolution are wrong, or observable SNRs are biased to a narrow range of ambient densities.

Supernova Remnant G11.2—0.3 and the ISM [PDF]
Symposium - International Astronomical Union, 2002 We present 610 and 235 MHz GMRT observations of the supernova remnant (SNR) G11.2—0.3 which shows a very large roation measure gradient (ΔRM∼1600 rad m−2) across it. The GMRT observations are the first high-resolution observations of this object at low frequencies.

Supernova Remnants and the ISM: Constraints from Cosmic-Ray Acceleration [PDF]
International Astronomical Union Colloquium, 1988 AbstractSupernova remnants can reaccelerate cosmic rays and modify their distribution during the cosmic ray propagation in the galaxy. Cosmic ray observations (in particular the boron-to-carbon data) strongly limit the permitted amount of reacceleration, which is used to set an upper limit on the expansion of supernova remnants, and a lower limit on ...

An Isolated, Recently Shocked ISM Cloud in the Cygnus Loop Supernova Remnant
The Astronomical Journal, 2002 Spatially resolved ROSAT X-ray and ground-based optical data for the southwestern region of the Cygnus Loop supernova remnant (SNR) reveal in unprecedented detail the very early stages of a blast-wave interaction with an isolated interstellar cloud.

Bioethics, Volume 40, Issue 8, Page 793-807, October 2026.ABSTRACT This paper examines Israel's destruction and ‘humanitarianisation’ of Palestinian health systems, arguing that this should be understood as an instance of ‘necropolitics,’ as conceived by Achille Mbembe. We review the extensive, long‐term destruction of health systems in Palestine before 7 October 2023 and the catastrophic acceleration of that

, 2006 We explore the importance of anisotropic thermal conduction in the evolution of supernova remnants via numerical simulations. The mean temperature of the bubble of hot gas is decreased by a factor of ~3 compared to simulations without thermal conduction, together with an increase in the mean density of hot gas by a similar factor.

An Account of Luck, Fortune, and Fate
Philosophy and Phenomenological Research, Volume 113, Issue 1, Page 16-28, July 2026.ABSTRACT Luck is one of our most important concepts. In this article, I first argue that extant accounts of luck are deeply flawed. I then argue for a hybrid account of luck that is based around the difference between skill‐based and non‐skill‐based events.
