J-PAS will soon start imaging 8000 deg2 of the northern sky with its unique set of 56 filters (R $\sim$ 60). Before, we observed 1 deg2 on the AEGIS field with an interim camera with all the J-PAS filters. With this data (miniJPAS), we aim at proving the scientific potential of J-PAS to identify and characterize the galaxy populations with the goal of performing galaxy evolution studies across cosmic time. Several SED-fitting codes are used to constrain the stellar population properties of a complete flux-limited sample (rSDSS <= 22.5 AB) of miniJPAS galaxies that extends up to z = 1. We find consistent results on the galaxy properties derived from the different codes, independently of the galaxy spectral-type or redshift. For galaxies with SNR>=10, we estimate that the J-PAS photometric system allows to derive stellar population properties with a precision that is equivalent to that obtained with spectroscopic surveys of similar SNR. By using the dust-corrected (u-r) colour-mass diagram, a powerful proxy to characterize galaxy populations, we find that the fraction of red and blue galaxies evolves with cosmic time, with red galaxies being $\sim$ 38% and $\sim$ 18% of the whole population at z = 0.1 and z = 0.5, respectively. At all redshifts, the more massive galaxies belong to the red sequence and these galaxies are typically older and more metal rich than their counterparts in the blue cloud. Our results confirm that with J-PAS data we will be able to analyze large samples of galaxies up to z $\sim$ 1, with galaxy stellar masses above of log(M$_*$/M$_{\odot}$) $\sim$ 8.9, 9.5, and 9.9 at z = 0.3, 0.5, and 0.7, respectively. The SFH of a complete sub-sample of galaxies selected at z $\sim$ 0.1 with log(M$_*$/M$_{\odot}$) > 8.3 constrain the cosmic evolution of the star formation rate density up to z $\sim$ 3 in good agreement with results from cosmological surveys.

Correction to the photometric colors of the Gaia Data Release 2 with the stellar color regression method
第二次盖亚数据发布(DR 2)提供了整个天空的精确和均匀的测光数据,达到了G,GRP和GBP通带前所未有的毫量级(mmag)水平。然而,在10 mmag水平上存在的星等依赖系统效应限制了其在科学开发中的力量。在这项工作中,使用大约50万颗与LAMOST DR 5相同的恒星,我们应用基于光谱的恒星颜色回归方法来校准Gaia G-GRP和GBP-GRP的颜色。以前所未有的精度约1毫等,系统的趋势与G星等揭示了两种颜色的非常详细,反映了仪器配置的变化。对GBP-GRP和亮度大于G~11.5等的恒星,发现了颜色依赖的趋势,刻度一般可达20 mmag,变化范围为几mmag/mag,给出了Gaia DR 2的修正色图,并简要讨论了一些应用。
