A method to extract p-modes frequencies from solar like stars acoustic spectra with S/N = 1/100
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...
A Minor-Merger Origin for Inner Disks and Rings in Early-Type Galaxies
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...
A modern DevOps and serverless architecture for the New Robotic Telescope software infrastructure
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 Sun observed in Honduras during the total solar eclipse of 11 July 1991
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...
A Multi-Data Comparison of Shortwave Climate Forcing Changes
Traditionally the earth's reflectance has been assumed to be roughly constant, but large decadal variability, not reproduced by current climate models, has been...
