The ALHAMBRA survey: Evolution of galaxy clustering since z∼1
(Oxford University Press, 2014-06)
We study the clustering of galaxies as function of luminosity and redshift in the range 0.35< z < 1.25 using data from the Advanced Large Homogeneous Area Medium-Band Redshift Astronomical (ALHAMBRA) survey. The ALHAMBRA ...

Near-earth object 2012XJ112 as a source of bright bolides of achondritic nature
(Blackwell Publishing Ltd, 2014)
We analyse the likely link between the recently discovered near-Earth object 2012XJ112 and a bright fireball observed over the south of Spain on 2012 December 27. The bolide, with an absolute magnitude of -9 ± 1, was ...

Quasi-stellar objects in the ALHAMBRA survey: I. Photometric redshift accuracy based on 23 optical-NIR filter photometry
(EDP Sciences, 2012)
Context. Even the spectroscopic capabilities of today's ground and space-based observatories can not keep up with the enormous flow of detections (>10 5 deg -2) unveiled in modern cosmological surveys as: i) would be ...

Spectroscopy and orbital analysis of bright bolides observed over the Iberian Peninsula from 2010 to 2012
(Oxford University Press, 2013)
We present the analysis of the atmospheric trajectory and orbital data of four bright bolides observed over Spain, one of which is a potential meteorite dropping event. Their absolute magnitude ranges from -10 to -11. Two ...

Bright fireballs associated with the potentially hazardous asteroid 2007LQ19
(Oxford University Press, 2014)
We analyse here two very bright fireballs produced by the ablation in the atmosphere of two large meteoroids in 2009 and 2010. These slow-moving and deep-penetrating events were observed over Spain in the framework of our ...

Analysis of a superbolide from a Damocloid observed over Spain on July 13, 2012
(Oxford University Press, 2013-12)
A superbolide with an estimated absolute magnitude of-20±1was seen on 2012 July 13 over the centre and south of Spain. This extraordinary event, which was witnessed by numerous casual observers, was recorded in the framework ...

The Geminid meteoroid stream as a potential meteorite dropper: A case study
(Oxford University Press, 2013-12)
A Geminid fireball with an absolute magnitude of -13 was observed over the south of Spain on 2009 December 15. This extraordinarily bright event (the brightest Geminid ever recorded by our team) was imaged from two meteor ...
