The Evolution of Galaxies and Their Environment [PDF]

open access: yes
The Third Teton Summer School on Astrophysics discussed the formation of galaxies, star formation in galaxies, galaxies and quasars at high red shift, and the intergalactic and intercluster medium and cooling flows.

Galclaim: A tool to identify host galaxy of astrophysical transient sources

open access: yesSoftwareX, 2023
The Galclaim software is designed to identify association between astrophysical transient sources and host galaxy by computing the probability of chance alignment. It is distributed as an open source Python software. It is already used to identify, confirm or reject host galaxy candidates of GRBs and to validate or invalidate transient candidates in ...

Quantitative Assessment of GOES 8–15 > ${ >} $0.6 and > ${ >} $4 MeV Radiation Belt Electron Fluxes

open access: yesSpace Weather, Volume 23, Issue 3, March 2025.
Abstract On Geostationary Operational Environmental Satellites (GOES) 8–15 (1996–2020), the Energetic Particle Sensor (EPS) included three integral electron channels, with nominal lower energies of 0.6 MeV (E1), 2 MeV (E2) and 4 MeV (E3). The > ${ >} $2 MeV channel has received more attention than the other two channels, because it is used by the NOAA ...

The Galaxies of Nonstandard Enlargements of Infinite and Transfinite grpahs of Higher Ranks: II [PDF]

open access: yesarXiv, 2005
This report is an improvement of a prior report (Report 814). It sharpens the principal theorem (Theorem 5.1 of Report 814) and also simplifies its proof. There are also several minor changes involving clarifications and corrections of misprints. The prior abstract remins the same as follows: In a previous work, the galaxies of the nonstandard ...

ATLAS Probe: Breakthrough Science of Galaxy Evolution, Cosmology, Milky Way, and the Solar System [PDF]

open access: yes, 2019
Astrophysics Telescope for Large Area Spectroscopy Probe is a concept for a National Aeronautics and Space Administration probe-class space mission that will achieve ground-breaking science in the fields of galaxy evolution, cosmology, Milky Way, and the

The scientific potential of space-based gravitational wave detectors

open access: yes, 2014
The millihertz gravitational wave band can only be accessed with a space-based interferometer, but it is one of the richest in potential sources. Observations in this band have amazing scientific potential.

Stability and size of galaxies from Planck's constant [PDF]

open access: yesarXiv, 1999
Stability and characterisitic geometrical and kinematical sizes of galaxies are strictly related to a minimal characteristic action whose value is of order $h$, the Planck constant. We infer that quantum mechanics, in some sense, determines the structure and the size of galaxies.

Galaxy-Dark Matter Connection : from Astrophysics to Cosmology

open access: yes, 2009
Galaxy-galaxy (g-g) lensing represents an ideal technique to constrain the dark matter distribution on galaxy scales. The required accuracy in the signal can be achieved only by stacking many foreground galaxies and averaging the ellipticity of the resulting background galaxies.

Explanation of velocities distribution in the galaxies without the dark matter [PDF]

open access: yesarXiv, 2011
In this work, we submit the explanation of spectra of the rotary curves of galaxies on the basis of a vector theory of gravitation without regard to the dark matter hypothesis. We study the approximation of rotary curves in case of existing of the medium constant cyclic field by the example of a number of galaxies.
