Descripción
This paper presents stellar mass functions and i-band luminosity
functions for Sloan Digital Sky Survey (SDSS) galaxies with i < 21
using clustering redshifts. From these measurements, we also compute
targeting completeness measurements for the Baryon Oscillation
Spectroscopic Survey (BOSS). Clustering redshifts is a method of
obtaining the redshift distribution of a sample of galaxies with only
photometric information by measuring the angular cross-correlation with
a spectroscopic sample in different redshift bins. We construct a
spectroscopic sample containing data from the BOSS + eBOSS surveys,
allowing us to recover redshift distributions from photometric data out
to z ≃ 2.5. We produce k-corrected i-band luminosity functions and
stellar mass functions by applying clustering redshifts to SDSS DR8
galaxies in small bins of colour and magnitude. There is little
evolution in the mass function between 0.2 < z < 0.8, implying
that the most massive galaxies form most of their mass before z = 0.8.
These mass functions are used to produce stellar mass completeness
estimates for the BOSS, giving a stellar mass completeness of 80{{ per
cent}} above M⋆ > 1011.4 between 0.2 <
z < 0.7, with completeness falling significantly at redshifts higher
than 0.7, and at lower masses. Large photometric data sets will be
available in the near future (DECaLS, DES, Euclid), so this and similar
techniques will become increasingly useful in order to fully utilize
these data.

El Proyecto se estructura en dos partes, diferenciadas pero complementarias: morfología y dinámica. El estudio detallado de la morfología de la Vía Láctea pretende proveer una base de datos de distribución estelar en las regiones más alejadas y extintas de nuestra Galaxia, mediante el desarrollo de modelos semiempíricos a partir de la información
