SDSS-V is an all-sky, multi-epoch spectroscopic survey that will yield optical and IR spectra of over 6 million objects during its seven year lifetime (2020-2027). Using SDSS’s existing and anticipated new facilities at Apache Point and Las Campanas Observatories, SDSS-V will survey the entire sky — mapping the Milky Way using rapid, repeated observations, mapping […]

DR18 BHM Overview
Black Hole Mapper (BHM) emphasizes the study of quasars/AGN, as among Universe’s most luminous objects, powered by accretion onto supermassive black holes (SMBHs), and co-evolving via feedback with the host galaxies in which they reside. BHM exploits – with order(s) of magnitude advances – two hallmark characteristics of quasars: their marked variability on a range […]
DR18 Completed Spectroscopic Surveys
The Sloan Digital Sky Survey started routine observing in 2000, and since then has gone through four generations of surveys. The current generation is the Fifth Generation of Sloan Digital Sky Surveys (SDSS-V), and the data of its mapper programs can be found in Data Release 18. The following is a list of all the […]
