Abstract:
We derive the stellar mass function (SMF) of quiescent and
star-forming galaxies at z≤0.2 using 12-band (five broad plus seven
narrow) photometry from the Javalambre Photometric Local Universe
Survey (J-PLUS) third data release (DR3) over 3284 deg2, where the
narrow bands improve photometric-redshift and stellar property
precision relative to purely broadband surveys.
We selected ∼890000 galaxies with r≤20mag and photometric redshifts
in the range 0.05≤z≤0.20 over an effective area of 2881deg2,
corresponding to a comoving volume of V≃1.6x108Mpc3. Stellar
masses and star formation rates were derived through spectral energy
distribution (SED) fitting with the Code Investigating GALaxy Emission
(CIGALE), and confronted with spectroscopic samples. Galaxies were
classified as star-forming or quiescent based on their specific star
formation rate (sSFR), adopting a threshold of
log(sSFR[yr-1])=-10.2. We computed SMFs for both populations using
the 1/Vmax method, applied completeness corrections, and fit a
parametric single Schechter function.
The SMFs derived from J-PLUS DR3 are well described by Schechter
functions and agree with previous photometric and spectroscopic
studies. The characteristic mass for quiescent galaxies,
log(M*/M☉)=10.80, is higher by 0.4dex than that of star-forming
galaxies. The faint-end slope is steeper for star-forming galaxies
(alpha=-1.2) than for quiescent ones (aplha=-0.7). The quiescent
fraction increases by 40% per dex in stellar mass, reaching fQ>.95
at log(M*/M☉)>11. Comparisons with the GAlaxy Evolution and
Assembly (GAEA) semi-analytic model show an overabundance of simulated
star-forming galaxies, particularly at intermediate masses.
The SMFs and quiescent fraction from J-PLUS DR3 are consistent with
the literature and provide valuable constraints for galaxy formation
models. Quiescent galaxies represent 45% of the number density at log
M*>9 but contribute 75% of the stellar mass density. This work lays
the groundwork for studies of environmental quenching using J-PLUS.
The inclusion of seven narrowband filters improves redshift precision
by 20%, enabling more accurate SED fitting and galaxy classification.
These methods and findings can be extended with J-PAS, which will
provide deeper and higher-resolution photometry over a wider spectral
range.
Description:
We derive the stellar mass function (SMF) of quiescent and
star-forming galaxies in the low-redshift Universe using J-PLUS DR3
12-band optical photometry over 3284 deg2 (2881deg2 effective after
masking). We select galaxies with extinction-corrected r-band
magnitude rSDSS≤20 and photometric redshift 0.05≤zphot≤0.2025.
Stellar masses and star formation rates are obtained with CIGALE SED
fitting. Quiescent and star-forming classification uses a specific SFR
threshold of log(sSFR/yr-1)=-10.2. This catalog provides, for each
galaxy, positions, r-band magnitude, photometric redshift, stellar
mass and SFR with 1-sigma uncertainties, rest-frame (g-i) color and
its uncertainty, the SGLC star/galaxy probability, the ODDS
redshift-confidence parameter, and a quiescent flag.
Parent survey: J-PLUS DR3 (12 filters: ugriz + 7 medium/narrow bands).
Sky coverage: 3284 deg2 total; 2881 deg2 effective after masking
bright stars and artifacts.
Galaxy sample: rSDSS≤20, 0.05≤zphot≤0.2025, sglcprobstar<0.5.
Photometric redshifts: computed with LePhare; ODDS is the integral
of P(z) within zphot ± 0.03(1+zphot).
Physical parameters: stellar mass and SFR averaged over the last
10 Myr, derived with CIGALE.
Quiescent vs. star-forming split: log(sSFR/yr-1)=-10.2.
