Using N-body simulations, we study the origin of prolate rotation observed in the kinematic data for Andromeda II (And II), a dwarf spheroidal satellite of M31...
Angular anisotropy of the fusion-fission and quasifission fragments
The anisotropy in the angular distribution of the fusion-fission and quasifission fragments for the 16O + 238U , 19F + 208Pb and 32S + 208Pb reactions is...
Angular distribution of satellite galaxies from the Sloan Digital Sky Survey Data Release 4
We explore the angular distribution of two samples of satellite galaxies orbiting isolated hosts extracted from the Sloan Digital Sky Survey Data Release 4. We...
Angular momentum transfer between oscillations and rotation in subdwarf B hybrid pulsators
Context. Subdwarf B pulsators exhibit pressure (p) and/or gravity (g) modes. Their frequency spectra range from very simple, with few frequencies, to very rich...
Angular Size Test on the Expansion of the Universe
Assuming the standard cosmological model to be correct, the average linear size of the galaxies with the same luminosity is six times smaller at z = 3.2 than at...
Anisotropic collisions and impact circular polarization. Application to the solar Halpha line
Aims:In light of recent contradictory observational results concerning the atomic polarization of solar H I lines, our purpose is to present certain collisional...
Anisotropic satellite accretion on to the Local Group with HESTIA
How the cosmic web feeds haloes, and fuels galaxy formation is an open question with wide implications. This study explores the mass assembly in the Local Group...
Anisotropic satellite galaxy quenching modulated by black hole activity
The evolution of satellite galaxies is shaped by their constant interaction with the circumgalactic medium surrounding central galaxies, which in turn may be...
Anisotropy measurements of the cosmic microwave background radiation at intermediate angular scales
Galaxy formation by gravitational instability implies the presence of temperature fluctuations in the cosmic microwave background. New observations at 10.45 and...
