Mosaicking with cosmic microwave background interferometers [PDF]
, 2006 Measurements of cosmic microwave background (CMB) anisotropies by interferometers offer several advantages over single-dish observations. The formalism for analyzing interferometer CMB data is well developed in the flat-sky approximation, valid for small

Radiative sky cooling: Fundamental principles, materials, and applications
Applied Physics Reviews, 2019 Radiative sky cooling cools an object on the earth by emitting thermal infrared radiation to the cold universe through the atmospheric window (8–13 μm). It consumes no electricity and has great potential to be explored for cooling of buildings, vehicles,

Spectroscopic Target Selection in the Sloan Digital Sky Survey: The Main Galaxy Sample [PDF]
, 2002 We describe the algorithm that selects the main sample of galaxies for spectroscopy in the Sloan Digital Sky Survey (SDSS) from the photometric data obtained by the imaging survey.

The Wiener-Filtered COBE DMR Data and Predictions for the Tenerife Experiment [PDF]
, 1995 We apply a Wiener filter to the two-year COBE DMR data. The resulting sky map has significantly reduced noise levels compared to the raw data: the most prominent hot and cold spots are significant at the 4-sigma level.

Composite Quasar Spectra from the Sloan Digital Sky Survey [PDF]
, 2001 We have created a variety of composite quasar spectra using a homogeneous data set of over 2200 spectra from the Sloan Digital Sky Survey (SDSS). The quasar sample spans a redshift range of 0.044 ≤ z ≤ 4.789 and an absolute r' magnitude range of -18.0 to

From cloud computing to sky computing
USENIX Workshop on Hot Topics in Operating Systems, 2021 We consider the future of cloud computing and ask how we might guide it towards a more coherent service we call sky computing. The barriers are more economic than technical, and we propose reciprocal peering as a key enabling step.

Towards a Phenomenology of Shakespeare’s Sky
Linguaculture, 2023 This paper begins with a phenomenological analysis of the sky as understood by early modern beholders via its synonyms: ‘sky’, ‘welkin’, ‘element’, ‘vault’, ‘heavens’, and ‘firmament’.

, 2000 We develop a new method for estimating and removing the spectrum of the sky from deep spectroscopic observations; our method does not rely on simultaneous measurement of the sky spectrum with the object spectrum.

The Sky Is Not the Limit: LTE for Unmanned Aerial Vehicles [PDF]
IEEE Communications Magazine, 2017 Many use cases of UAVs require beyond visual LOS communications. Mobile networks offer wide-area, high-speed, and secure wireless connectivity, which can enhance control and safety of UAV operations and enable beyond visual LOS use cases. In this article,
