The miniJPAS Survey: A Study on Wavelength Dependence of the Photon Response Non-uniformity of the JPAS-{\it Pathfinder} Camera
Kai Xiao, Haibo Yuan, J. Varela +20
Understanding the origins of small-scale flats of CCDs and their wavelength-dependent variations plays an important role in high-precision photometric, astrometric, and shape measu…
Data Release 2 of S-PLUS: accurate template-fitting based photometry covering 1000 square degrees in 12 optical filters
F. Almeida-Fernandes, L. Sampedro, F. R. Herpich +26
The Southern Photometric Local Universe Survey (S-PLUS) is an ongoing survey of 9300 deg in the southern sky in a 12-band photometric system. This paper presents the seco…
The miniJPAS survey: star-galaxy classification using machine learning
P. O. Baqui, V. Marra, L. Casarini +31
Future astrophysical surveys such as J-PAS will produce very large datasets, which will require the deployment of accurate and efficient Machine Learning (ML) methods. In this work…
J-PLUS: photometric calibration of large area multi-filter surveys with stellar and white dwarf loci
C. López-Sanjuan, J. Varela, D. Cristóbal-Hornillos +22
We present the photometric calibration of the twelve optical passbands observed by the Javalambre Photometric Local Universe Survey (J-PLUS). The proposed calibration method has fo…
Studying focal ratio degradation of optical fibers for Subaru Prime Focus Spectrograph
Jesulino Bispo dos Santos, Antonio Cesar de Oliveira, James Gunn +9
Focal Ration Degradation (FRD) is a change in light angular distribution caused by fiber optics. FRD is important to fiber-fed, spectroscopic astronomical systems because it can ca…
Multi-fibers connectors systems for FOCCoS-PFS-Subaru
Antonio Cesar de Oliveira, Ligia Souza de Oliveira, Lucas Souza Marrara +8
The Fiber Optical Cable and Connector System (FOCCoS), provides optical connection between 2400 positioners and a set of spectrographs through optical fibers cables as part of PFS…
Fiber Optical Cable and Connector System (FOCCoS) for PFS/Subaru
Antonio Cesar de Oliveira, Lígia Souza de Oliveira, Márcio V. de Arruda +29
FOCCoS, Fiber Optical Cable and Connector System, has the main function of capturing the direct light from the focal plane of Subaru Telescope using optical fibers, each one with a…
Progress with the Prime Focus Spectrograph for the Subaru Telescope: a massively multiplexed optical and near-infrared fiber spectrograph
Hajime Sugai, Naoyuki Tamura, Hiroshi Karoji +81
The Prime Focus Spectrograph (PFS) is an optical/near-infrared multi-fiber spectrograph with 2394 science fibers, which are distributed in 1.3 degree diameter field of view at Suba…
Goals and strategies in the global control design of the OAJ Robotic Observatory
A. Yanes-Díaz, S. Rueda-Teruel, J. L. Antón +21
There are many ways to solve the challenging problem of making a high performance robotic observatory from scratch. The Observatorio Astrofísico de Javalambre (OAJ) is a new astron…
