Galaxy evolution is likely to be shaped by negative feedback from active galactic nuclei (AGN). In the whole range of redshifts and luminosities studied so far, galaxies hosting an AGN frequently show fast and extended outflows consisting in both ionized and molecular gas. Such outflows could potentially quench the start formation within the host galaxy, but a clear evidence of negative feedbac...

Abstract The surfaces of neutron stars are sources strongly polarized soft X-rays due to the presence strong magnetic fields. Radiative transfer mediated by electron scattering and free–free absorption is central defining local surface anisotropy polarization signatures. Scattering transport influenced complicated interplay between linear circular polarizations. This complexity has been capture...

The Star algorithm is an effective and efficient algorithm for graph clustering. We propose a series of novel, yet simple, metrics for the selection of Star centers in the Star algorithm and its variants. We empirically study the performance of off-line, standard and extended, and on-line versions of the Star algorithm adapted to the various metrics and show that one of the proposed metrics out...

In the paper, Binet’s first formula for the logarithm of the gamma function is extended, inequalities and star-shaped and sub-additive properties of the extended remainder of Binet’s first formula for the logarithm of the gamma function are presented, and completely monotonic properties of the difference between extended remainders of Binet’s first formula for the logarithm of the gamma functio...
