Pérez González, Pablo Guillermo ; Cardiel López, Nicolás ; Gallego Maestro, Jesús | Wiley | 2014-10-11We are undertaking a search for high-redshift low-luminosity Lyman Alpha sources in the SHARDS (Survey for High-z Absorption Red and Dead Sources) survey. Among the pre-selected Lyman Alpha sources two candidates were spotted, located 3.19 arcse[...]![]()

Borlaff, Alejandro ; Eliche Moral, María del Carmen ; Beckman, John E. ; Ciambur, Bogdan C. ; Pérez González, Pablo Guillermo ; Barro, Guillermo ; Cava, Antonio ; Cardiel López, Nicolás | EDP Sciencies | 2017-08Context. The controversy about the origin of the structure of early-type S0-E/S0 galaxies may be due to the difficulty of comparing surface brightness profiles with different depths, photometric corrections and point spread function (PSF) effect[...]![]()

The spectral energy distributions (SED) of dusty galaxies at intermediate redshift may look similar to very high-redshift galaxies in the optical/near infrared (NIR) domain. This can lead to the contamination of high-redshift galaxy searches bas[...]![]()
