Block time step storage scheme forastrophysical n-body simulations
(IOP Publishing, 2015)
Astrophysical research in recent decades has made significant progress thanks to the availability of various N-body simulation techniques. With the rapid development of high-performance computing technologies, modern ...
Shapley Supercluster Survey: construction of the photometric catalogues and i-band data release
(Oxford University Press, 2015)
The Shapley Supercluster Survey is a multi-wavelength survey covering an area of similar to 23 deg(2) (similar to 260 Mpc(2) at z = 0.048) around the supercluster core, including nine Abell and two poor clusters, having ...
VVVX near-IR photometry for 99 low-mass stars in the Gaia EDR3 Catalog of Nearby Stars
(2022)
Context. Red dwarf stars, which represent 75% of stars in the Milky Way, can be studied in great detail in the solar neighborhood, where the sample is more complete.Aims. We intend to better characterize red-dwarf candidates ...
DECISION TREE CLASSIFIERS FOR STAR/GALAXY SEPARATION
(IOP PUBLISHING LTD, 2011)
We study the star/galaxy classification efficiency of 13 different decision tree algorithms applied to photometric objects in the Sloan Digital Sky Survey Data Release Seven (SDSS-DR7). Each algorithm is defined by a set ...
