Analysis of the escape in systems with four exit channels
Mathematical Methods in the Applied Sciences, Volume 46, Issue 1, Page 1032-1044, 15 January 2023., 2023 In this paper, we have performed a numerical investigation of the escape of a particle from two different dynamical systems with the same number of exit channels. We have chosen specific values of the parameters of the systems so that the openings of the potential well in both systems are approximately of the same size.

A Bayesian Approach to the Vertical Structure of the Disk of the Milky Way
The Open Journal of Astrophysics, 2020 This work investigates the vertical profile of the stars in the disk of the Milky Way. The models investigated are of the form sech2/n(nz/(2H)) where, setting α = 2/n, the three functions of the sequence α= 0, 1, 2 correspond to exponential, sech, and ...

The Impact of GRBs on Exoplanetary Habitability
Universe, 2023 Can high-energy transient events affect life on a planet? We provide a review of the works that have tried to answer this question. It is argued that that gamma ray bursts, specifically those of the long class, are among the most dangerous astrophysical ...

Breaking the hierarchy of galaxy formation [PDF]
, 2005 Recent observations of the distant Universe suggest that much of the stellar mass of bright galaxies was already in place at z > 1. This presents a challenge for models of galaxy formation because massive halos are assembled late in the hierarchical ...

Rotation-invariant convolutional neural networks for galaxy morphology prediction [PDF]
arXiv.org, 2015 Measuring the morphological parameters of galaxies is a key requirement for studying their formation and evolution. Surveys such as the Sloan Digital Sky Survey have resulted in the availability of very large collections of images, which have permitted ...

Dwarf galaxy formation induced by galaxy interactions [PDF]
, 2000 Growing evidence has been accumulated for that some gas-rich dwarf galaxies are formed from material liberated by galaxy collisions and/or mergers. Also, gas-poor dwarf elliptical galaxies are often found in the central regions of clusters of galaxies.

Molecular Oncology, EarlyView.Large multidimensional digital images of cancer tissue are becoming prolific, but many challenges exist to automatically extract relevant information from them using computational tools. We describe publicly available resources that have been developed jointly by expert and non‐expert computational biologists working together during a virtual hackathon

The 2dF Galaxy Redshift Survey: spectra and redshifts [PDF]
, 2001 The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250 000 galaxies. This paper describes the survey design, the spectroscopic observations, the redshift measurements and the survey data base.
