A rare sextuple-merging brightest cluster galaxy system in a disturbed galaxy cluster observed with the Einstein Probe Follow-up X-ray Telescope

open access: yesAstronomy & Astrophysics
The evolutionary processes of galaxy clusters influence the properties of their member galaxies. We present a joint X-ray–optical analysis of the galaxy cluster WHY J050106.2+013714 at zc = 0.151.

High energy astrophysical processes

open access: yes, 2005
We briefly review the high energy astrophysical processes that are related to the production of high energy $γ$-ray and neutrino signals and are likely to be important for the energy loss of high and ultrahigh energy cosmic rays. We also give examples for neutrino fluxes generated by different astrophysical objects and describe the cosmological link ...
