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 ...

A large lunar impact blast on September 11th 2013
(Oxford University Press, 2014)
On 2013 September 11 at 20h07m28 .s 68 ± 0 .s 01 UTC, two telescopes operated in the framework of our lunar impact flashes monitoring project recorded an extraordinary flash produced by the impact on the Moon of a large ...

The nature of the gould belt from a fractal analysis of its stellar population
(IOP Publishing Ltd., 2007-09-20)
he Gould Belt (GB) is a system of gas and young, bright stars distributed along a plane that is inclined with respect to the main plane of the Milky Way. Observational evidence suggests that the GB is our closest star ...

The alhambra survey: evolution of galaxy spectral segregation
(IOP Publishing Ltd., 2016-02-20)
We study the clustering of galaxies as a function of spectral type and redshift in the range 0.35 <z <1.1 using data from the Advanced Large Homogeneous Area Medium Band Redshift Astronomical (ALHAMBRA) survey. The data ...

The alhambra survey: a large area multimedium-band optical and near-infrared photometric survey
(IOP Publishing Ltd., 2008-09)
Here we describe the first results of the Advanced Large Homogeneous Area Medium-Band Redshift Astronomical (ALHAMBRA) survey, which provides cosmic tomography of the evolution of the contents of the universe over most of ...

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 ...

Hierarchical star formation: Stars and stellar clusters in the Gould Belt
(Oxford University Press, 2009)
We perform a study of the spatial and kinematical distribution of young open clusters in the solar neighbourhood, discerning between bound clusters and transient stellar condensations within our sample. Then, we discriminate ...

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 ...

Metallicity maps of the globular cluster system in the galaxy
(IOP Publishing Ltd., 1993-01-10)
The spatial metallicity distribution in the Galaxy, as depicted by the globular cluster system, is analyzed. Two metallicity maps (on the ω - |Z| plane) corresponding to the halo and disk subsamples (Zinn 1985) have been ...
