We present a comprehensive multiwavelength photometric analysis of the innermost (˜3 × 3 kpc2) 110 globular clusters (GCs) of M87. Their spectral energy...
The Instituto Astrofisica de Canarias-Bartol Cosmic Microwave Background Anisotropy Experiment: Results of the 1994 Campaign
We present the results of a cosmic microwave background (CMB) anisotropy ground-based millimetric experiment sensitive to fluctuations on angular scales of ~2...
The instrumental polarization of a Gregory-coude telescope
A theoretical model of the polarization properties of a Gregory-coude telescope is calculated to predict the behavior of the German Gregory-coude telescope...
The INT Photometric Hα Survey of the Northern Galactic Plane (IPHAS)
The Isaac Newton Telescope (INT) Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is a 1800-deg2 CCD survey of the northern Milky Way spanning the...
The INT Search for Metal-Poor Stars: Spectroscopic Observations and Classification via Artificial Neural Networks
With the dual aims of enlarging the list of extremely metal-poor stars identified in the Galaxy and boosting the numbers of moderately metal-deficient stars in...
The integral equation approach to the study of interplanetary dust
Some considerations about the zodiacal light brightness integral from the stand point of the theory of integral equations are made. It is shown that for...
The INTEGRAL IBIS/ISGRI System Point Spread Function and Source Location Accuracy
The imager on board INTEGRAL (IBIS) presently provides the most detailed sky images ever obtained at energies above 30 keV. The telescope is based on a coded...
The integrated magnetic field of the Sun as seen by GOLF on board SOHO
An objective of the GOLF experiment (Global Oscillations at Low Frequencies) on-board the SOHO (Solar and Heliospheric Observatory) space mission was to measure...
The intense production of silicates during the final AGB phases of intermediate mass stars
Context. The formation of silicates in circumstellar envelopes of stars evolving through the asymptotic giant branch (AGB) is still highly debated given the...
