On Periodic Groups and Shunkov Groups that are Saturated by Dihedral Groups and $A_5$

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
A group is said to be periodic, if any of its elements is of finite order. A Shunkov group is a group in which any pair of conjugate elements generates Finite subgroup with preservation of this property when passing to factor groups by finite Subgroups ...

Euclid preparation. XVIII. The NISP photometric system [PDF]

open access: yesAstronomy & Astrophysics, 2022
Euclid will be the first space mission to survey most of the extragalactic sky in the 0.95-2.02 $\mu$m range, to a 5$\sigma$ point-source median depth of 24.4 AB mag. This unique photometric data set will find wide use beyond Euclid's core science.
