Neutrino treatment in multidimensional astrophysical simulations : a new spectral scheme [PDF]

open access: yes, 2014
Neutrinos play a central role in modern physics and astrophysics. Their extremely weak interaction rate with baryons and other leptons makes their detection on the Earth difficult and challenging.

Supernova [PDF]

open access: yes, 2020
We present a description of one of the most spectacular astronomical events that exist in our universe, the supernova explosions. We describe the physical features that present the stars that are precursors of these events, the way and the physical ...

Abundance Tomography of Type Ia Supernovae [PDF]

open access: yes, 2004
Many uncertainties about the physics of Type Ia Supernovae have been revealed in the recent past, and numerous pieces are puzzled together to achieve a complete description of the phenomenon of thermonuclear explosions in the sky. However, very important

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

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

SN 2023ixf: The Closest Supernova of the Decade

open access: yesUniverse
Supernova 2023ixf occurred on 18 May 2023 in the nearby galaxy Messier 101 (D≈6.85 Mpc), making it the closest supernova in the last decade. Following its discovery, astronomers around the world rushed to observe the explosion across the electromagnetic ...

Azidophosphonamido Rhodium(I) and Iridium(I) Complexes: Synthesis, Properties, and Linkage Isomerism

open access: yesChemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.
A family of azidophosphonamido ligands and their corresponding rhodium(I) and iridium(I) complexes were synthesized. The rich reaction chemistry of these species revealed unusual linkage isomerization processes and bonding motifs. M = Rh, Ir; Mes = 2,4,6‐Me3C6H2. ABSTRACT A series of azidophosphonamido rhodium(I) and iridium(I) complexes ([iPr2P(N3R)NR]

Quantitative comparison between Type Ia supernova spectra at low and high redshifts: A case study [PDF]

open access: yes, 2008
We develop a method to measure the strength of the absorption features in type Ia supernova (SN Ia) spectra and use it to make a quantitative comparisons between the spectra of type Ia supernovae at low and high redshifts.
