Quasars belong to the most energetic phenomena in the universe. Physical
processes at the origin of them can be explained in the framework of the AGN unified scenario. The unified scenario predicts two classes of
quasars, obscured and unobscured ones, depending on the orientation of
the dusty torus which surrounds the central supermassive black hole.
Variability is ubiquitous in AGN, and may be generated by several
phenomena that would produce different footprints. Determining the
nature and origin of the variability is a key subject to understand the
differences between the different types of AGNs.
The OTELO project is the extragalactic survey currently under way using
the tunable filters of the OSIRIS instrument at the GTC. OTELO is
already providing the deepest emission line object survey of the
universe up to a redshift 7. In this contribution, the status of the
survey and the first results obtained will be presented.
The Observatorio Astrofísico de Javalambre (OAJ), is a new
astronomical facility located in the Sierra de Javalambre
(Teruel,Spain). The observatory will host two telescopes, an 83cm
telescope with one 9.2k x 9.2k CCD and a 2.55 telescope with 14 CCDs
10.5K x 10.5K The OAJ control system has been designed from a global
point of view including astronomical subsystems as well as
infrastructures and other facilities. We strongly believe that the best
approach for a success design of a new observatory is to consider it as
whole and to focus on overall efficiency basically integrated by…
The Observatorio Astrofísico de Javalambre (OAJ) is a new
astronomical facility located at the Sierra de Javalambre (Teruel,
Spain) whose primary role will be to conduct all-sky astronomical
surveys. The OAJ facility will have two wide-field telescopes: the
T250/JST; a 2.55-m telescope with a 3° diameter FoV, and the
T80/JAST; a 0.83 m telescope with a 2° diameter FoV. In this poster
the JAST/T80 and JST/T250 first light panoramic instruments are
presented. T80Cam is a wide-field camera that will be mounted at the
Cassegrain focus of the T80/JAST. It is intended for surveys, starting
with…
Observational strategy is a critical path in any large survey. The
planning of a night requires the knowledge of the fields observed, the
quality of the data already secured, and the ones still to be observed
to optimize scientific returns. Finally, field maximum altitude, sky
distance/brightness during the night and meteorological data (cloud
coverage and seeing) have to be taken into account in order to increase
the chance to have a successful observation. To support the execution of
the J-PAS project at the Javalambre Astrophysical Observatory, we have
prepared a scheduler and a…
