Superluminous supernovae : theory and observations [PDF]

, 2013
textThe discovery of superluminous supernovae in the past decade challenged our understanding of explosive stellar death. Subsequent extensive observations of superluminous supernova light curves and spectra has provided some insight for the nature of ...

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.

Prophylaxis Strategies for SARS‐CoV‐2 Infection in Adults With Hematological Malignancies in Saudi Arabia: Consensus Statements From the Working Group on COVID‐19 Management in Hematological Malignancies

Cancer Reports, Volume 9, Issue 10, October 2026.
ABSTRACT Background Despite the end of the pandemic phase, patients with hematological malignancies (HMs) remain vulnerable to severe COVID‐19 infection and mortality. Prophylaxis strategies, including vaccination and monoclonal antibodies (mAbs) like AZD7442, are crucial for protection.

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 ...

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

Journal 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

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

Open 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.

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

Bioethics, 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
