DESTRUCTION OF THE INTERSTELLAR CLOUDS BY THESHOCK WAVES

Odessa Astronomical Publications, 2008
We study the influence of the interstellar cloud structure irregularity on the dynamics of its destruction by a supernova shock wave. It is shown that irregular clouds are destroyed twice quickly as the spherical ones.

Physical Correlations and Predictions Emerging from Modern Core-collapse Supernova Theory

The Astrophysical Journal Letters
In this paper, we derive correlations between core-collapse supernova observables and progenitor core structures that emerge from our suite of 20 state-of-the-art 3D core-collapse supernova simulations carried to late times.

Contributions of supernovae to the chemical and dynamical evolution of the ism [PDF]

International Astronomical Union Colloquium, 1989
ABSTRACT:Supernovae of Types Ia, Ib, and II contribute, on average, 1051 ergs of turbulent energy to the interstellar medium for each 2 Mo of new heavy elements. This permits a dynamical extension of the homogeneous one-zone model (with constant IMF and instantaneous recycling) that is familiar from studies of galactic chemical evolution.

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Simulating supernova feedback in galaxy disks [PDF]

, 2012
In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

Unveiling the Central Engine of Core-collapse Supernovae in the Local Universe: Neutron Star or Black Hole?

The Astrophysical Journal Letters
The physical trigger powering supernovae following the core collapse of massive stars is believed to involve a neutron star (NS) or a black hole (BH), depending largely on progenitor mass.

Conversion Between 2‐ and 3‐Dimensional Halogen‐Bonded Networks Formed From a Single N‐Oxide/Iodoalkyne Building Block

Chemistry – A European Journal, EarlyView.
Open halogen‐bonded networks have been prepared from building blocks that incorporate both iodoalkyne halogen bond donors and a pyridine‐N‐oxide halogen bond acceptor. An initially‐formed 3D network containing dioxane in its channels undergoes an unprecedented transition to a 2D material when crystals are exposed to diethyl ether.

A Two-moment Neutrino Transport Scheme for the CHIMERA Supernova Code

The Astrophysical Journal Supplement Series
We introduce our two-moment scheme, referred to as A-M1 (analytic closure-M1), to solve the neutrino Boltzmann transport equation with the aim of using it to replace the flux-limited diffusion (FLD) scheme currently utilized in C himera .

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
