Consensus clustering-based undersampling for improved classification of transient events in time-domain astronomy surveys. [PDF]

Sci Rep
Astronomical data analytics has rapidly expanded given the advancement of data handling techniques and computing system. The race to discover new events is subject to acquiring and digesting the high volume of data from sky surveys efficiently, yet ...

How Swift is redefining time domain astronomy [PDF]

Journal of High Energy Astrophysics, 2015
NASA's Swift satellite has completed ten years of amazing discoveries in time domain astronomy. Its primary mission is to chase gamma-ray bursts (GRBs), but due to its scheduling flexibility it has subsequently become a prime discovery machine for new ...

The GROWTH Marshal: A Dynamic Science Portal for Time-domain Astronomy [PDF]

Publications of the Astronomical Society of the Pacific, 2019
We describe a dynamic science portal called the GROWTH Marshal that allows time-domain astronomers to define science programs; program filters to save sources from different discovery streams; coordinate follow-up with various robotic or classical ...

Coherent Time-domain Canceling of Interference for Radio Astronomy

Publications of the Astronomical Society of the Pacific, 2022
Abstract Radio astronomy is vulnerable to interference from a variety of anthropogenic sources. Among the many strategies for mitigation of this interference is coherent time-domain canceling (CTC), which ideally allows one to “look through” interference, as opposed to avoiding the interference or deleting the afflicted data.

Time-domain Astronomy with the GMRT: uGMRT to eGMRT [PDF]

Proceedings of the International Astronomical Union, 2017
The upgraded GMRT (uGMRT) with its unprecedented sensitivity and high figure of merit, is expected to result in the discovery of a large population of pulsars including pulsars of previously unknown type.

Data Management in Time-Domain Astronomy: Requirements and Challenges [PDF]

International Conference on Big Scientific Data Management, 2018
In time-domain astronomy, we need to use the relational database to manage star catalog data. With the development of sky survey technology, the size of star catalog data is larger, and the speed of data generation is faster. So, in this paper, we make a

Meteor Sky in Time-Domain Astronomy

Proceedings of the International Astronomical Union, 2017
AbstractMulti-wave astronomy provides a means for researchers to see and ‘hear’ the sky. But that is only part of their perception of the cosmos. The hot handshake of the Universe in the form of a meteor substance burning in the Earth’s atmosphere, sometimes with the precipitation of meteorites threatening the environment, occurs every second.

Fundamental physics studies in time domain and multi-messenger astronomy [PDF]

Frontiers in Astronomy and Space Sciences
The era of ime domain and multi-messenger astronomy is not only leading to the development of a much broader set of detectors and instruments for astrophysical observations, but is also providing the means for astronomy to tie directly to cutting-edge ...
