Let M be a von Neumann algebra, f a faithful normal state and denote by M^f the fixed point algebra of the modular group of f. Let U_M and U_{M^f} be the...
Let $B$ be a C$^*$-algebra and $X$ a C$^*$ Hilbert $B$-module. If $pin B$ is a projection, denote by $S_p ={xin X : x,x> =p}$, the $p$-sphere of $X$. For $phi$...
The High Optical Resolution Spectrograph (HORus) has been available on the 10-m GTC telescope since early 2019. Based largely on optical elements reused from...
Host galaxies, BH Masses and Eddington Ratio of Radio-Loud AGNs
We compare the host galaxies properties of BL Lac objects with those of radio loud quasars (RLQs) imaged by the WFPC2 on board of HST. The considered objects (z
