PublicaciónHigh redshift galaxies in the ALHAMBRA survey. II. Strengthening the evidence of bright-end excess in UV luminosity functions at 2.5 ≤ z≤ 4.5 by PDF analysis
Context. Knowing the exact shape of the ultraviolet (UV) luminosity function (LF) of high-redshift galaxies is important to understand the star formation...

PublicaciónHα luminosity function of H II regions: preliminary calibration of a powerful standard candle
We propose the use of the H II region luminosity function (LF) as a refined powerful standard candle for extragalactic distances. We have found evidence of a...

PublicaciónImpact of metallicity and star formation rate on the time-dependent, galaxy-wide stellar initial mass function
The stellar initial mass function (IMF) is commonly assumed to be an invariant probability density distribution function of initial stellar masses. These...

PublicaciónIs the initial mass function of low surface brightness galaxies dominated by low-mass stars?
The rotation curves of low surface brightness (LSB) galaxies suggest that they possess significantly higher mass-to-light (M/L) ratios than their high surface...
