The POEMMA (Probe of Extreme Multi-Messenger Astrophysics) observatory [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from space with sensitivity over the full celestial sky.

Astrophysics in 2006 [PDF]

Space Science Reviews, 2007
The fastest pulsar and the slowest nova; the oldest galaxies and the youngest stars; the weirdest life forms and the commonest dwarfs; the highest energy particles and the lowest energy photons. These were some of the extremes of Astrophysics 2006. We attempt also to bring you updates on things of which there is currently only one (habitable planets ...

The neutrino magnetic moment portal: cosmology, astrophysics, and direct detection [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
We revisit the physics of neutrino magnetic moments, focusing in particular on the case where the right-handed, or sterile, neutrinos are heavier (up to several MeV) than the left-handed Standard Model neutrinos.

Nuclear astrophysics [PDF]

Reports on Progress in Physics, 1999
Nuclear astrophysics is that branch of astrophysics which helps understanding some of the many facets of the Universe through the knowledge of the microcosm of the atomic nucleus. In the last decades much advance has been made in nuclear astrophysics thanks to the sometimes spectacular progress in the modelling of the structure and evolution of the ...

Domain-Agnostic Outlier Ranking Algorithms—A Configurable Pipeline for Facilitating Outlier Detection in Scientific Datasets

Frontiers in Astronomy and Space Sciences, 2022
Automatic detection of outliers is universally needed when working with scientific datasets, e.g., for cleaning datasets or flagging novel samples to guide instrument acquisition or scientific analysis.

The Evolution of Stars and Astrophysics

Communications of the Byurakan Astrophysical Observatory, 2022
Ambartsumian published this article in Russian 75 years ago. In this work, he showed for the first time that star formation was not interrupted in the past, but continues in our cosmological time. His conclusion was that at the same time as the old stars,

The Resonant Bremsstrahlung of Ultrarelativistic Electrons on a Nucleus with Radiation of Hard Gamma-Quanta in the Presence of a Pulsed Field of the X-ray Pulsar

Universe, 2020
The investigation scrutinizes the circulation of the large-scaled fluxes of ultrarelativistic electrons near the neutron stars. This work focuses on the effects that occur during the adjustment of the strong electromagnetic field near the X-ray pulsars ...
