Holding the Cosmos in Your Hand: Developing 3D Modeling and Printing Pipelines for Communications and Research

open access: yesFrontiers in Earth Science, 2020
Three-dimensional (3D) visualization has opened up a Universe of possible scientific data representations. 3D printing has the potential to make seemingly abstract and esoteric data sets accessible, particularly through the lens of translating data into ...

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

open access: yesUniverse, 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 ...

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

open access: yesFrontiers 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.

Less Known Results on the Solar System [PDF]

open access: yesINCAS Bulletin, 2021
For a two half millennium evolution of knowledge from the Democrit’s natural, rational atomized material conception to the Newtonian, Maxwellian, Einsteinian mathematized physics, the research in the most cases has followed a deductive route from ...

The Mg/Fe ratio of silicate minerals in the meteoritic materials and in the circumstellar environment: A case study for the chondritic-like composition

open access: yesOpen Astronomy, 2021
Kaba meteorite as a reference material (one of a least metamorphosed and most primitive carbonaceous chondrites fell on Earth) was chosen for this study providing an adequate background for study of the protoplanetary disk or even the crystallization ...

Practical Limits on Nanosatellite Telescope Pointing: The Impact of Disturbances and Photon Noise

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Accurate and stable spacecraft pointing is a requirement of many astronomical observations. Pointing particularly challenges nanosatellites because of an unfavorable surface area–to-mass ratio and a proportionally large volume required for even the ...

Visible Shapes of Black Holes M87* and SgrA*

open access: yesUniverse, 2020
We review the physical origins for possible visible images of the supermassive black hole M87* in the galaxy M87 and SgrA* in the Milky Way Galaxy. The classical dark black hole shadow of the maximal size is visible in the case of luminous background ...

Astrophysics in 2006 [PDF]

open access: yesSpace 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 ...
