Estimation of the detected background by the future gamma ray transient mission CAMELOT
Astronomische Nachrichten, Volume 340, Issue 7, Page 666-673, August 2019., 2019 Abstract This study presents a background estimation for the CubeSats Applied for MEasuring and LOcalising Transients (CAMELOT), which is a proposed fleet of nanosatellites for the all‐sky monitoring and timing‐based localization of gamma ray transients with precise localization capability at low Earth orbits.

The Fractal Geometry of the Cosmic Web and Its Formation
Advances in Astronomy, Volume 2019, Issue 1, 2019., 2019 The cosmic web structure is studied with the concepts and methods of fractal geometry, employing the adhesion model of cosmological dynamics as a basic reference. The structures of matter clusters and cosmic voids in cosmological N‐body simulations or the Sloan Digital Sky Survey are elucidated by means of multifractal geometry.

The Astrophysical Journal, 2023 Observed breakBRD (“break bulges in red disks”) galaxies are a nearby sample of face-on disk galaxies with particularly centrally concentrated star formation: they have red disks but recent star formation in their centers as measured by the D _n 4000 ...

The Natural Science Underlying Big History
The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 Nature’s many varied complex systems—including galaxies, stars, planets, life, and society—are islands of order within the increasingly disordered Universe. All organized systems are subject to physical, biological, or cultural evolution, which together comprise the grander interdisciplinary subject of cosmic evolution.

Numerical Relativity as a Tool for Studying the Early Universe
Journal of Gravity, Volume 2014, Issue 1, 2014., 2014 Numerical simulations are becoming a more effective tool for conducting detailed investigations into the evolution of our universe. In this paper, we show how the framework of numerical relativity can be used for studying cosmological models. The author is working to develop a large‐scale simulation of the dynamical processes in the early universe ...

The FRB 20190520B Sight Line Intersects Foreground Galaxy Clusters
The Astrophysical Journal Letters, 2023 The repeating fast radio burst FRB 20190520B is an anomaly of the FRB population thanks to its high dispersion measure (DM = 1205 pc cm ^−3 ) despite its low redshift of z _frb = 0.241.

Chemodynamical Simulations of Dwarf Galaxy Evolution
Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014 In this review I give a summary of the state of the art for what concerns the chemo‐dynamical numerical modelling of galaxies in general and of dwarf galaxies in particular. In particular, I focus my attention on (i) initial conditions, (ii) the equations to solve; (iii) the star formation process in galaxies, (iv) the initial mass function, (v) the ...

Galaxy Quenching from Cosmic Web Detachment
The Open Journal of Astrophysics, 2019 We propose the Cosmic Web Detachment (CWD) model, a framework to interpret the star-formation history of galaxies in a cosmological context. The CWD model unifies several starvation mechanisms known to disrupt or stop star formation into one single ...
