The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
Pre-selection of the Candidate Fields for Deep Imaging of the Epoch of Reionization with SKA1-Low
Qian Zheng, Xiang-Ping Wu, Quan Guo +4
The Square Kilometre Array (SKA) will be the first low-frequency instrument with the capability to directly image the structures of the Epoch of Reionization (EoR). Indeed, deep im…
The localization of single pulse in VLBI observation
Lei Liu, Wu Jiang, Weimin Zheng +4
In our previous work, we propose a cross spectrum based method to extract single pulse signals from RFI contaminated data, which is originated from geodetic VLBI postprocessing. Th…
Testing General Relativity with geodetic VLBI: what profit from a single, specially designed experiment?
Oleg Titov, Anastasiia Girdiuk, Sebastien Lambert +15
Context. We highlight the capabilities of the geodetic VLBI technique to test General relativity in the classical astrometric style, i.e., measuring the deflection of light in the…
Gaia Data Release 2: The astrometric solution
L. Lindegren, J. Hernandez, A. Bombrun +87
Gaia Data Release 2 (Gaia DR2) contains results for 1693 million sources in the magnitude range 3 to 21 based on observations collected by the European Space Agency Gaia satellite…
Overview of the DESI Legacy Imaging Surveys
Arjun Dey, David J. Schlegel, Dustin Lang +157
The DESI Legacy Imaging Surveys are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Surve…
