Dynamical evolution of a supernova driven turbulent interstellar medium [PDF]

Proceedings of the International Astronomical Union, 2006
AbstractIt is shown that a number of key observations of the Galactic ISM can be understood, if it is treated as a highly compressible and turbulent medium, energized predominantly by supernova explosions (and stellar winds). We have performed extensive numerical high resolution 3D hydrodynamical and magnetohydrodynamical simulations with adaptive mesh

Neutrino-nucleus reactions and their role in supernova dynamics and nucleosynthesis [PDF]

Neutrino reactions on nuclei play important roles for the dynamics of supernovae and their associated nucleosynthesis. This manuscript summarizes the current status in deriving the relevant cross sections for supernova neutrinos and briefly discusses a ...

Neutrino oscillations at high densities: cosmological and astrophysical aspects [PDF]

, 2011
This doctoral thesis treats the effects of neutrino oscillations in the early universe and supernovae. The main probe for the context of the early universe is big bang nucleosynthesis (BBN).

Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters With Interstellar Cold Clouds and Nearby Supernovae

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

Evolution of the first supernovae in protogalaxies: Dynamics of mixing of heavy elements [PDF]

Astronomy Reports, 2012
The paper considers the evolution of the supernova envelopes produced by Population III stars with masses of $M_*\sim 25-200 M_\odot$ located in non-rotating protogalaxies with masses of $M\sim 10^7 M_\odot$ at redshifts $z=12$, with dark-matter density profiles in the form of modified isothermal spheres.

SN 2007gr: a Normal Type Ic Supernova with a Mildly Relativistic Radio Jet? [PDF]

, 2010
A nearby type Ic supernova, SN 2007gr was observed with the EVN in two epochs 60 days apart (second observation also included the Green Bank Telescope).

Supernova neutrinos: collective and matter effects at large detectors

, 2011
I briefly outline our current understanding of the neutrino flavor conversions inside a supernova, describe the possible signals the neutrino detectors should look for, and comment on the extent to which these signals would reveal the neutrino mixing ...

Constraining the Onset Density for the QCD Phase Transition with the Neutrino Signal from Core-collapse Supernovae

The Astrophysical Journal
The occurrence of a first-order hadron–quark matter phase transition at high baryon densities is investigated in astrophysical simulations of core-collapse supernovae, to decipher yet incompletely understood properties of the dense matter equation of ...

Energy‐Dependent Nucleation and Hierarchical Aggregation of Gold Nanoparticles During Synchrotron X‐Ray Radiolysis Revealed by in Situ Transmission Imaging and SAXS

Nano Select, Volume 7, Issue 10, October 2026.
In situ x‐ray transmission imaging and monochromatic small angle x‐ray scattering (SAXS) measurements of Au precursor solution establish that precise tuning of incident photon energy controls not only the radiolytic yield but the entire hierarchical aggregation trajectory, offering a sophisticated blueprint for the rational design of functional ...
