Deep co-added sky from Catalina Sky Survey images [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT A number of synoptic sky surveys are underway or being planned. Typically, they are done with small telescopes and relatively short exposure times. A search for transient or variable sources involves comparison with deeper baseline images, ideally obtained through the same telescope and camera. With that in mind, we have stacked

Machine Learning: Science and Technology, 2023 Artificial intelligence methods show great promise in increasing the quality and speed of work with large astronomical datasets, but the high complexity of these methods leads to the extraction of dataset-specific, non-robust features.

The Sloan Digital Sky Survey [PDF]
Computing in Science & Engineering, 1998 Astronomy is about to undergo a major paradigm shift, with data sets becoming larger and more homogeneous, designed for the first time in a top-down fashion. The paper discusses the Sloan Digital Sky Survey. By digitally mapping half of the northern sky, this project promises to radically improve the way scientists do astronomy.

Radio Continuum Surveys of the Sky [PDF]
Symposium - International Astronomical Union, 1988 Radio continuum surveys give us the fundamental information about the distribution of the radio intensity across the sky. The radio waves originate in three fundamental emitting processes and are measured superposed in the antenna beam. At the lowest radio frequencies (below 10 GHz) the nonthermal emission process (synchrotron radiation) predominates ...

Long-Term Optical Monitoring of Blazars
Galaxies, 2019 Systematic monitoring of specific targets in the optical regime was historically applied on a very narrow sample of known variable stars. The discovery of blazars in the 20th century brought to the foreground the need for new global sky surveys, covering

Aircraft surveys for air eDNA: probing biodiversity in the sky [PDF]
PeerJ, 2023 Air is a medium for dispersal of environmental DNA (eDNA) carried in bioaerosols, yet the atmosphere is mostly unexplored as a source of genetic material encompassing all domains of life.

Mapping The Sky - Surveys With Schmidt Telescopes [PDF]
Symposium - International Astronomical Union, 1988 This paper describes the sky surveys carried out over the past 30 years by the three large Schmidt Telescopes; the Palomar 1.2m Schmidt, the ESO 1m Schmidt and the UK 1.2m Schmidt. Developments in photographic technology, the reproduction of the surveys as sky atlases and problems associated with the storage of original plates are discussed.
