Supernovae Detection with Fully Convolutional One-Stage Framework

open access: yesSensors, 2021
A series of sky surveys were launched in search of supernovae and generated a tremendous amount of data, which pushed astronomy into a new era of big data.

Modeling and Simulation of Sky Survey

open access: yesApplied Sciences, 2021
Sky surveys with wide and deep field are the key direction of international astronomy research for the next decades. It is worthwhile to study how to design a sky survey algorithm to obtain the maximum scientific output in a limited period of observation.

Deep co-added sky from Catalina Sky Survey images [PDF]

open access: yesMonthly 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

DeepAstroUDA: semi-supervised universal domain adaptation for cross-survey galaxy morphology classification and anomaly detection

open access: yesMachine 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]

open access: yesComputing 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]

open access: yesSymposium - 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

open access: yesGalaxies, 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

Prediction of interior daylight under clear sky conditions. [PDF]

open access: yes, 1996
Most available techniques for predicting internal daylight illuminance do not take into account reflected sunlight, nor the fact that under clear sky conditions the direction of the illuminance is usually upwards, not downwards from the sky.
