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 ...

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.

High-Energy Astrophysics in the 2020s and Beyond [PDF]

open access: yes, 2019
With each passing decade, we gain new appreciation for the dynamic, connected, and often violent nature of the Universe. This reality necessarily places the study of high-energy processes at the very heart of modern astrophysics.

The astrophysical behavior of open clusters along the Milky Way Galaxy

open access: yesNRIAG Journal of Astronomy and Geophysics, 2014
The main aim of this paper is to study the astrophysical behavior of open clusters' properties along the Milky Way Galaxy. Near-IR JHK (2MASS) photometry has been used for getting a homogeneous Catalog of 263 open clusters' parameters, which are studied for the first time by the author through the last five years.

Studying the evolution of large-scale structure with the VIMOS-VLT Deep Survey

open access: yes, 2007
The VIMOS-VLT Deep Survey (VVDS) currently offers a unique combination of depth, angular size and number of measured galaxies among surveys of the distant Universe: ~ 11,000 spectra over 0.5 deg2 to I_{AB}=24 (VVDS-Deep), 35,000 spectra over ~ 7 deg2 to ...
