The Scientific Potential of LOFAR for Time Domain Astronomy [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractLOFAR is a ground-breaking low-frequency radio telescope that is currently nearing completion across northern Europe. As a software telescope with no moving parts, enormous fields of view and multi-beaming, it has fantastic potential for the exploration of the time-variable universe. In this brief paper I outline LOFAR's capabilities, our plans

Time domain astronomy with Swift and Fermi
Rwanda Journal, 2016 Swift and Fermi are unveiling an unexpectedly rich tapestry of behavior in the transient γ−ray sky. Sources which were already known to be transient − such as pulsars, gamma-ray bursts, and blazars − have been studied in ever-increasing detail. For example, Fermi/LAT has detected 117 pulsars of which 56 are new.

Time-domain astronomy with the Fermi GBM [PDF]
Proceedings of 35th International Cosmic Ray Conference — PoS(ICRC2017), 2017 The Fermi Gamma-ray Burst Monitor (GBM) is an all-sky monitoring instrument sensitive to energies from 8 keV to 40 MeV. Over the past 8 years of operation, the GBM has detected over 240 gamma-ray bursts per year and provided timely GCN notices with localization to few-degree accuracy for follow-up observations. In addition to GRBs, Galactic transients,

Data Management in Time-Domain Astronomy: Requirements and Challenges [PDF]
, 2019 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 systematic and comprehensive introduction to process the data in time-domain astronomy, and ...

A key to the treasure chest of time-domain astronomy
, 2022 Abstract Time-domain astronomy has emerged as one of the most promising fields in astronomy. Time-frequency analysis methods like Fourier and wavelet transforms are widely used in astronomy but have profound limitations in analysing nonlinear or non-stationary data, which are dominant in natural systems.
