... For this paper: postscript PPEUC CMB index 1 Introduction.. ... Istituto TESRE, Consiglio Nazionale delle Ricerche, Via Gobetti 101, 40129 Bologna, Italy . ... We examine the effects of amplifiers gain fluctuations, of fluctuations in the amplifiers noise temperatures, in the reference load temperature and in the DC gain ratio. We find that gain fluctuations are suppressed by proper gain modulation, leaving fluctuations in the amplifiers noise temperatures as the main source of type noise. ...

... Electronic Raman scattering in Tl 2 Ba 2 CuO 6+ d : Symmetry of the order parameter, oxygen doping effects, and normal-state scattering. Abstract: . Single crystals of the optimally doped, moderately and strongly overdoped high-temperature superconductor Tl 2 Ba 2 CuO 6+ d (Tl-2201) with T c = 80, 56, and 30 K, respectively, have been investigated by polarized Raman scattering. ...

... The object is remarkable because of its low estimated mass and age and because it is associated with a mid-infrared source, an indication of a surrounding dusty disk. Based on the comparison of our spectrum with similar spectra of field M-dwarfs and atmospheric models, we obtain revised estimates of the spectral type, effective temperature and luminosity of the central object. ...

We investigate models for main-sequence and horizontal-branch (HB) stars constructed using the Carson opacities and make comparisons with models based on the Cox-Stewart opacities. ... The drop in the hydrogen-shell luminosity due to the helium-core expansion during HB evolution is greater than that obtained with the Cox-Stewart opacities. ... Studies of main-sequence (MS) stars lead to agreement with Stothers' (1974a,b, 1976) results for homogeneous models constructed with Carson opacities. ...

... 1) The MS lower envelopes for groups of stars with different metallicities turn out to be coincident. ... 4) The conformation of the kinematics of stars within narrow ranges ob b-y with the ages derived from isohrones reveals that, at Z < Z , the isohrone ages seem to be increasingly overestimated with growing b-y . ... At a given metallicity, they have a much narrower MS and the locus of their MS lower envelope seems to be brighter for the metal-rich group of stars. ...

Abstract: I will present the determination of the mass of the supermassive black hole of Centaurus A using high-resolution integral-field observations of both the gas and the stellar kinematics. ... The black hole mass measurements of both tracers, gas and stars, are in excellent agreement and provide one of the cleanest gas versus stars comparisons of a BH mass determination. ...

Nongravitational Effects on Cometary Motion due to Jupiter . ... The problem of linking cometary apparitions before and after the approach of a comet to Jupiter was investigated. A hypothesis of possible existence of additional acceleration, perturbing the motion of comets in the vicinity of Jupiter, was considered. This nongravitational perturbation is described by a function of the jovicentric distance, written in a standard "force law" form. ...
