Neutrino radiation hydrodynamics in hot and dense nuclear matter and the role of microphysics in simulations of massive stars [PDF]

open access: yes, 2010
The main results of my doctoral studies were obtained from core collapse simulations of massive stars using a numerical model based on radiation hydrodynamics and three-flavour Boltzmann neutrino transport in spherical symmetry.

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

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
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

Core-collapse supernovae in the great survey era [PDF]

open access: yes, 2011
A new class of wide-field, repeated-scan optical sky surveys, such as LSST, is coming online, and will map the sky in the time domain with unprecedented depth, completeness, and dynamic range.

Type Ia supernovae from sub-Chandrasekhar mass white dwarfs

open access: yes, 2016
We argue that detonations of sub-Chandrasekhar mass white dwarfs can lead to bright explosions with light curves and spectra similar to those of observed Type Ia supernovae.

On the Destruction and Humanitarianisation of the Health System in Gaza and the Need for a Biopolitical Bioethics

open access: yesBioethics, 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

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Synthesis and Characterization of the Molybdenum Carbonyl‐Functionalized Zintl Ions [(η4‐Pb4)Mo(CO)3]4− and [Pb4{Mo(CO)3}3]6−

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 13, 1 September 2026.
The reaction of the tetrahedral [Pb4]4− with Mo(CO)4(tmeda) yields two different Mo(CO)3‐functionalized clusters which can both be related to known clusters by the same substitution pattern following the isolobal principle. The crystal structures of [Na([2.2.2]crypt)]2Na2[(η4‐Pb4)Mo(CO)3] · 8.7NH3 and Na6[Pb4{Mo(CO)3}3] · 22NH3 are reported.

Hydrodynamic Studies of the Evolution of Recurrent, Symbiotic and Dwarf Novae: the White Dwarf Components are Growing in Mass

open access: yesOpen Astronomy, 2012
Symbiotic binaries are systems containing white dwarfs (WDs) and red giants. Symbiotic novae are those systems in which thermonuclear eruptions occur on the WD components.
