Observations for surveying the Universe have revealed the first supernova found during the J-PAS project. The CEFCA scientific team located it in a spiral galaxy, like the Milky Way, at a distance of about 700 million light years. Its discovery has already been reported to the International Astronomical Union (IAU).
An algorithm developed by researcher Andrés del Pino now applies Bayesian neural networks to data from the J-PLUS project. The aim is to robustly classify the astronomical objects detected by the survey and thus differentiate stars, quasars and galaxies. The research has been published in Astronomy and Astrophysics.
The first survey data show 100 000 stars and about 450 000 galaxies. It is the first scientific demonstration of the power of the combination of the JST250 wide-field telescope and its JPCam panoramic camera. J-PAS, led by the Centro de Estudios de Física del Cosmos de Aragón (CEFCA) and the Instituto de Astrofísica de Andalucía (IAA-CSIC) in Spain, makes available to the scientific community the first 12 square degrees of the three-dimensional map of the universe that it is carrying out from the Observatorio Astrofísico de Javalambre.ars.
The OAJ and Galáctica have been two of the places chosen to tell the story of Aragonese culture and contributions to astronomy throughout history.
A binocular telescope like the one that will be launched on a satellite into space in 2030 will arrive at the Aragonese observatory in the coming weeks. The ARRAKIHS mission will take images from Pico del Buitre for at least the next two years. They will be used to improve all data processing and analysis and to refine the observational strategy in a team led by Dr Antonio Marín-Franch. The goal is to observe nearby galaxies at unprecedented depths in search of the stellar trails predicted by the standard cosmological model and which have so far proved elusive.
Yale University, in coordination with the Peter and Patricia Gruber Foundation, has announced that the Gruber Cosmology Prize of 2018 is for all the "Planck" mission team of the European Space Agency, and specially for its scientific leaders, N. Mandolesi and J.-L Puget. Two CEFCA scientists, from the Research Group "Astrophysics with Large Surveys" of the Government of Aragón, have been members of the Planck mission and have been awarded as co-participants.

Scientists discover ring around dwarf planet Haumea

2017-10-16 10:00 all science participated projects

The belt of transneptunian objects holds four dwarf planets including Haumea which is unusual for its elongated and fast-rotating body.

A stellar occultation has allowed to determine the main physical characteristics of this body, unknown until now, including the discovery of a ring.

CEFCA joins ESA's Euclid Mission

2016-10-25 11:45 all science participated projects
A collaboration agreement between the Euclid Consortium of the European Space Agency (ESA)-led space mission Euclid- and the Centro de Estudios de Física del Cosmos de Aragón (CEFCA; Teruel) has been signed for the provision of ground based scientific data with the Observatorio Astrofísico de Javalambre to complement the observations of the Euclid space telescope.

Ten thousand million year of cosmic evolution at hand

2013-11-13 10:30 all science participated projects
The complete catalog of ALHAMBRA project will be published tomorrow. It consists on a mapping of the space to study the evolution of the universe over the last ten billion years. ALHAMBRA has identified, classified and calculated the distance of more than half a million galaxies spread over eight regions of the sky. The development of this catalog has been performed by the Observatorio de Calar Alto with the collaboration of researchers of the Centro de Estudios de Física del Cosmos de Aragón.

ALHAMBRA-gold catalogue published

2013-06-24 13:46 all science participated projects

As the ALHAMBRA project maps in detail eight deep separate regions of the universe, it is the best available tool to study the recent history of the universe. This first release of the data, which is called ALHAMBRA-gold, contains one hundred thousand galaxies, twenty thousand stars and one thousand possible active galactic nuclei. Several researchers of CEFCA have participated in the development of this catalogue, which has been conducted by the Calar Alto Observatory.

Planck shows an homogeneous Universe

2013-03-26 21:00 all science participated projects
On March 21, the Planck scientific team released the first set of cosmology results based on data obtained during the first 15.5 months of the Space Telescope's operation. This has been done be means of almost thirty scientific articles in which the Cosmology group of CEFCA has been involved.
