The necessity of finding a signal buried in noise is a common problem in astrophysics where noise limited observations are usually preceding interesting...

More than half square degree in the region of the Lockman Hole has been observed at 14.3μm with the ISOCAM camera on board ISO. We analyzed these data using the...

Nuclear disks and rings are frequent galaxy substructures, for a wide range of morphological types [from S0 to Sc, see e.g., 1, 2]. We have investigated the...

The forthcoming New Robotic Telescope, a collaboration between the UK and Spain, is poised to become the world's largest and fastest autonomous observatory...

In a previous work (Eff-Darwich & Pérez-Hernández 1997), it was presented a new inversion method based on the Regularized Least Squares technique. This new...

A morphological description of the solar photosphere, chromosphere, and the corona is presented from a complete sequence of visual and spectroscopic...

We study a sample of 20 galaxies with an observed central drop in the stellar velocity dispersion (σ-drop) matched with a control sample of galaxies without a σ...

Traditionally the earth's reflectance has been assumed to be roughly constant, but large decadal variability, not reproduced by current climate models, has been...
