... Because the DMR instrument is differential and every pixel is multiply sampled, sky maps are produced by solving a coupled system of linear equations (the normal equations) to minimize a chi-squared. ... This is reflected in the algebraic form of the normal equations matrix, so that, if one were to diagonalize the matrix, one would find a single eigenvector whose eigenvalue was identically zero, and the associated eigenvector, viewed as a sky map, would have a constant value. ...

... The active time at each angular bin is the sum over frames of the active time contributions from all CCD pixels, within the node-specific telemetry window, which overlap the surface of the bin. ... The active time, per frame, of a normal pixel is the full frame integration time multiplied by the node-specific fractional exposure; bad pixels contribute no active time. ... If an event is rejected for this reason only, then its pixels remain normal in the exposure map. ...

La scoperta visuale della SN 1995G in NGC 1643. ... E', da poco, iniziata una nuova era nella mia attivitа di ricerca di SNe.

... Programme . ... Abstract: -ray signatures of hadronic acceleration in Centaurus A are investigated. Using two different models for the generation of ultra-high energy cosmic rays (UHECR) in active galactic nuclei and normalizing the UHECR flux of Centaurus A to the observations of the Pierre Auger Observatory, we calculate the accompanying high energy -ray flux in the GeV to TeV range. ...

Recent evidence suggests that the Universe is filled with something termed "Dark Energy". ... Baryons are normal particles (e.g. protons and neutrons) which make up all of ordinary matter. ... What are some resolutions to this problem and how do "Low Surface Brightness Galaxies" fit in to the problem of missing baryons. ... In this exercise, you will use a computational engine to model two interacting galaxies to see if you can reproduce the observed morphology of two real systems. ...

... We propose that the bimodal nature of the kick velocity distribu­ tion of radio pulsars is connected to the dichotomy between hadronic stars (i.e. neutron stars with no quark matter content) and quark stars. ... Here we propose a scenario in which the low­velocity part of the distribution is connected with normal (hadronic) compact stars, and high­velocity part is formed by objects with some amount of quark matter inside (hybrid or strange stars). ...

This diagram illustrates a floating image that overlaps the borders of two paragraphs in normal flow: the paragraph borders are clipped by the non-transparent parts of the image. ... A left-floating image causes the final three lines of the upper paragraph to float along its right side. It causes the first three lines of the following paragraph to do the same, and the remainder of that paragraph flows normally.
