J-PLUS: The star formation main sequence and rate density at d less than or similar to 75 Mpc
Based on observations made with the JAST/T80 telescope for J-PLUS project at the Observatorio Astrofisico de Javalambre in Teruel, a Spanish Infraestructura Cientifico-Tecnica Singular (ICTS) owned, managed and operated by the Centro de Estudios de Fisica del Cosmos de Aragon (CEFCA). Data has been processed and provided by CEFCA's Unit of Processing and Archiving Data (UPAD). Funding for the J-PLUS Project has been provided by the Governments of Spain and Aragon through the Fondo de Inversiones de Teruel; the Aragon Government through the Research Groups E96, E103, and E16_17R; the Spanish Ministry of Science, Innovation and Universities (MCIU/AEI/FEDER, UE) with grants PGC2018-097585-B-C21 and PGC2018-097585-B-C22; the Spanish Ministry of Economy and Competitiveness (MINECO) under AYA2015-66211-C2-1-P, AYA2015-66211-C2-2, AYA2012-30789, and ICTS-2009-14; and European FEDER funding (FCDD104E-867, FCDD13-4E-2685). The Brazilian agencies FINEP, FAPESP, and the National Observatory of Brazil have also contributed to this project.

We thank the help of Prof. G. Gavazzi in the analysis and understanding of Hff3 data. This research has made use of the NASA/IPAC Extragalactic Database (NED), which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration. This research made use of Astropy, a community-developed core Python package for Astronomy (Astropy Collaboration 2013), and Matplotlib, a 2D graphics package used for Python for publication-quality image generation across user interfaces and operating systems (Hunter 2007). Some of the data sets discussed in the manuscript were recovered with WebPlotDigitizer (https://automeris.io/WebPlotDigitizer/index.html), a free software developed to facilitate easy and accurate data extraction from a variety of plot types. ; Aims. Our goal is to estimate the star formation main sequence (SFMS) and the star formation rate density (SFRD) at z <= 0.017 (d less than or similar to 75 Mpc) using the Javalambre Photometric Local Universe Survey (J-PLUS) first data release, that probes 897.4 deg(2) with twelve optical bands.Methods. We extract the H alpha emission flux of 805 local galaxies from the J-PLUS filter J0660, being the continuum level estimated with the other eleven J-PLUS bands, and the dust attenuation and nitrogen contamination corrected with empirical relations. Stellar masses (M-star), H alpha luminosities (L-H alpha), and star formation rates (SFRs) were estimated by accounting for parameters covariances. Our sample comprises 689 blue galaxies and 67 red galaxies, classified in the (u-g) vs. (g-z) color-color diagram, plus 49 AGN.Results. The SFMS is explored at log M-star greater than or similar to 8 and it is clearly defined by the blue galaxies, with the red galaxies located below them. The SFMS is described as log SFR=0.83log M-star-8.44. We find a good agreement with previous estimations of the SFMS, especially those based on integral field spectroscopy. The H alpha luminosity function of the AGN-free sample is well described by a Schechter function with log L-H alpha = 41.34 log L H alpha = 41.34 , log (*)=-2.43, and alpha=-1.25. Our measurements provide a lower characteristic luminosity than several previous studies in the literature.Conclusions. The derived star formation rate density at d less than or similar to 75 Mpc is log rho (SFR)=-2.10 +/- 0.11, with red galaxies accounting for 15% of the SFRD. Our value is lower than previous estimations at similar redshift, and provides a local reference for evolutionary studies regarding the star formation history of the Universe. ; Government of Spain through the Fondo de Inversiones de Teruel ; Government of Aragon through the Fondo de Inversiones de Teruel ; Spanish Ministry of Science, Innovation and Universities (MCIU/AEI/FEDER, UE) PGC2018-097585-B-C21 PGC2018-097585-B-C22 ; Spanish Ministry of Economy and Competitiveness (MINECO) AYA2015-66211-C2-1-P AYA2015-66211-C2-2 AYA2012-30789 ICTS-2009-14 ; European FEDER funding FCDD104E-867 FCDD13-4E-2685 ; State Agency for Research of the Spanish MCIU through the "Center of Excellence Severo Ochoa" award SEV2017-0709 AYA2016-79724-C4-4P ; Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ) ; Fundacao de Apoio a Pesquisa do Distrito Federal (FAPDF) 308105/2018-4 ; Financiadora de Estudos e Projetos -FINEP through the National Observatory of Brazil REF. 1217/13 -01.13.0279.00 REF 0859/10 -01.10.0663.00 ; National Aeronautics & Space Administration (NASA) ; Aragon Government through the Research Group E96 Aragon Government through the Research Group E103 Aragon Government through the Research Group E16_17R
