The LOFAR LBA Sky Survey [PDF]
Astronomy & Astrophysics, 2021 Context. The LOw Frequency ARray (LOFAR) is the only radio telescope that is presently capable of high-sensitivity, high-resolution (i.e. < 1 mJy beam−1 and < 15″) observations at ultra-low frequencies (< 100 MHz). To utilise these capabilities, the LOFAR Surveys Key Science Project is undertaking a large survey to cover the entire northern ...

The VLA Low‐frequency Sky Survey [PDF]
Astronomische Nachrichten, 2006 AbstractWe present an overview of the ongoing VLA Low‐frequency Sky Survey (VLSS, formerly known as 4MASS). The VLSS will map an area of 9.1 sr covering the entire sky above a declination of –30 degrees (or 75% of the full sky), at a frequency of 74 MHz (4 meter wavelength) with an unprecedented combination of sensitivity and resolution at this low ...

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

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.

Proceedings of The many facets of extragalactic radio surveys: towards new scientific challenges — PoS(EXTRA-RADSUR2015), 2016 The VLA All-Sky Survey (VLASS) builds upon the newly upgraded Karl G. Jansky Very Large Array (VLA) to employ its enhanced bandwidth, time resolution, and survey speed to carry out a next-generation sky survey. VLASS will map the sky at δ > −40°, covering a total of 33,885 square degrees, with 2.005 angular resolution using the VLA B-array at 2–4

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 ...

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.
