The current instrumentation plan for the E-ELT foresees a High Resolution Spectrograph conventionally indicated as HIRES. Shaped on the study of extra-solar...

I describe how the principles of lexicography have been applied in limited ways in astronomy and look at the revision work under way for the third edition of...

A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these...

We have obtained NIR broad-band images in the J, H and K bands of 12 barred galaxies that make up our sample, during three observing runs with the 3.6 m Canada...

Let $X$ be a compact Kahler manifold, and let $L$ be a line bundle on $X.$ Define $I_k(L)$ to be the kernel of the multiplication map $ Sym^k H^0 (L) o H^0 (L^k...

Seeing statistics from several year-long site-testing campaigns carried out at different locations at the Roque de los Muchachos Observatory (ORM) are reviewed...

In order to compare the use of the classical Fourier Transform and the Homomorphic Deconvolution (HD), ring diagram analysis using both techniques has been...

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 $phi$...
