The group Fuentes de Alta Energía en la Galaxia (Spanish for High-Energy Sources in the Galaxy) was
founded in the University of Jaén in 2002 as a research group led by Prof. Josep Martí Ribas and supported by
the Plan Andaluz de Investigación, Desarrollo e Innovación of the Andalusian Government. Our research line is
the multi-wavelength study of the high-energy sources in the Galaxy, mainly microquasars and unidentified gamma-ray sources
with known counterparts at lower energies. In order to carry out this task, our group is funded by both Andalusian and
The group is currently constituted by eight doctors and two PhD students. Six of them work at Andalusian centers: Pedro Luis
Luque Escamilla (current responsible for the Research Group) and Josep Martí Ribas, from the University of
Jaén; José Martínez Aroza, from the University of Granada; Juan Ramón Sánchez Sutil, from
the IES San Juan Bosco de Jaén; and the graduate students at the University of Jaén, Álvaro J.
Muñoz Arjonilla and Estrella Sánchez Ayaso. In addition, there are four external collaborators from
institutions outside of Andalucía: Gustavo E. Romero and Jorge A. Combi, from the University of La Plata; J. Facundo
Albacete Colombo, from the University of Comahue, and Josep María Paredes, from the University of Barcelona.
The group Fuentes de Alta Energía en la Galaxia continues the ancient astronomical tradition in Jaén, that
dates back to the times of
Abu Abd Allah Muhammad ibn Muadh Al-Jayyani,
an astronomer who lived in Jaén between the 10th and 11th centuries A. D., where he worked as a judge. Al-Jayyani observed a very
long solar eclipse that occurred on July 1, 1079. Al-Jayyani's most important contributions to Astronomy were the first treatise on
spherical trigonometry in history, that were later used by Regiomontanus, and the Tabulae Jahen, some tables with astronomical
measurements on the meridian that passes through Jaén. He also made contributions to Mathematics, Hydraulics and the theory of
sunrises and sunsets.
