Sloan Digital Sky Survey: Early Data Release [PDF]

open access: yesThe Astronomical Journal, 2002
The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey that will eventually cover approximately one-quarter of the celestial sphere and collect spectra of ≈106 galaxies, 100,000 quasars, 30,000 stars, and 30,000 serendipity targets. In 2001 June, the SDSS released to the general astronomical community its early data release, roughly

Photometric Redshift Forecast for the 7-Dimensional Sky Survey

open access: yesThe Astrophysical Journal
We investigate the expected accuracy of redshifts that can be obtained using low-resolution spectroscopic (medium-band) data from the 7-Dimensional Sky Survey (7DS). By leveraging 40 densely sampled filters with widths of FWHM = 25 nm, we create 7DS mock

The Near-Earth Object Surveyor Mission

open access: yesThe Planetary Science Journal, 2023
The Near-Earth Object (NEO) Surveyor mission is a NASA Observatory designed to discover and characterize asteroids and comets. The mission’s primary objective is to find the majority of objects large enough to cause severe regional impact damage (>140 m ...

The MOST Hosts Survey: Spectroscopic Observation of the Host Galaxies of ∼40,000 Transients Using DESI

open access: yesThe Astrophysical Journal Supplement Series
We present the Multi-Object Spectroscopy of Transient (MOST) Hosts survey. The survey is planned to run throughout the 5 yr of operation of the Dark Energy Spectroscopic Instrument (DESI) and will generate a spectroscopic catalog of the hosts of most ...

FOSSIL. III. Lightcurves of 371 Trans-Neptunian Objects

open access: yesThe Astrophysical Journal Supplement Series, 2023
From the first phase of the high-cadence Formation of the Outer Solar System: an Icy Legacy (FOSSIL) survey, we analyzed lightcurves, ranging from one to four nights in length, of 371 trans-Neptunian objects (TNOs) for periodicity.

The ESO Sky Surveys [PDF]

open access: yesInternational Astronomical Union Colloquium, 1984
AbstractTechnical aspects of the production of photographic Sky Surveys and Atlasses are discussed. The need to optimize all factors, e.g. telescope site, telescope optics, mechanics and control system, hypersensitization, calibration, processing and reproduction is illustrated by the ESO 1m Schmidt telescope and the ESO Sky Surveys.

The case low-dispersion northern sky survey. III [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 1983
AbstractThe Burrell Schmidt-type telescope of the Warner and Swasey Observatory in its new location on Kitt Peak in Arizona is being used for a spectroscopic survey of the region b > +30°. and δ > +30°. The plates, which cover 5° x 5° are taken with the 1.8 prism which provides a dispersion of 1350 Å mm-1 at Hγ. Eastman Kodak IIIa-J plates, baked
