The Apache Point Observatory Galactic Evolution Experiment (APOGEE)
Steven R. Majewski, Ricardo P. Schiavon, Peter M. Frinchaboy +75
The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its systematic, homogeneo…
The ASKAP/EMU Source Finding Data Challenge
A. M. Hopkins, M. T. Whiting, N. Seymour +31
The Evolutionary Map of the Universe (EMU) is a proposed radio continuum survey of the Southern Hemisphere up to declination +30 deg., with the Australian Square Kilometre Array Pa…
The LOFAR Multifrequency Snapshot Sky Survey (MSSS) I. Survey description and first results
G. H. Heald, R. F. Pizzo, E. Orrú +147
We present the Multifrequency Snapshot Sky Survey (MSSS), the first northern-sky LOFAR imaging survey. In this introductory paper, we first describe in detail the motivation and de…
Capabilities of future intensity interferometers for observing fast-rotating stars: imaging with two- and three-telescope correlations
Paul D. Nunez, Armando Domiciano de Souza
Future large arrays of telescopes, used as intensity interferometers, can be used to image the surfaces of stars with unprecedented angular resolution. Fast-rotating, hot stars are…
Distributed image reconstruction for very large arrays in radio astronomy
André Ferrari, David Mary, Rémi Flamary +1
Current and future radio interferometric arrays such as LOFAR and SKA are characterized by a paradox. Their large number of receptors (up to millions) allow theoretically unprecede…
Thermalizing a telescope in Antarctica: Analysis of ASTEP observations
Tristan Guillot, Lyu Abe, Abdelkrim Agabi +13
The installation and operation of a telescope in Antarctica represent particular challenges, in particular the requirement to operate at extremely cold temperatures, to cope with r…
