Inferring properties of the ISM from supernova remnant size distributions [PDF]

open access: greenMonthly 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.

MHD lensing in inhomogeneous ISM for qualitative understanding of  the morphology of supernova remnants [PDF]

open access: greenAstrophysics and Space Science
Abstract Morphological evolution of expanding shells of fast-mode magnetohydrodynamic (MHD) waves through an inhomogeneous ISM is investigated in order to qualitatively understand the complicated morphology of shell-type supernova remnants (SNR).

Supernova Remnant G11.2—0.3 and the ISM [PDF]

open access: bronzeSymposium - 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]

open access: bronzeInternational 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 ...

The impact of supernova remnants on the ISM in Starburst galaxies [PDF]

open access: bronzeProceedings 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.

An Isolated, Recently Shocked ISM Cloud in the Cygnus Loop Supernova Remnant [PDF]

open access: bronzeThe 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.

X-ray probes of the Magellanic Clouds: The supernova remnants and hot phase of the ISM

open access: green, 2019
Supernova remnants (SNRs) are key transmitters of stellar feedback to the interstellar medium (ISM). The shock waves produced in the death of stars carve out large structures and heat the ambient gas, while the metals produced during the life of the star and final explosion are released into the ISM.
