Time domain astronomy with the THESEUS satellite [PDF]

Experimental Astronomy, 2021
THESEUS is a medium size space mission of the European Space Agency, currently under evaluation for a possible launch in 2032. Its main objectives are to investigate the early Universe through the observation of gamma-ray bursts and to study the gravitational waves electromagnetic counterparts and neutrino events.

AMPEL: A framework for reproducible time-domain astronomy

, 2022
Reproducibility, a core principle of science, is close to impossible to achieve in its strict sense in time-domain astronomy - we cannot redo an observation of a transient event once it is gone. Related features such as provenance and analysis reproducibility is further challenged by fractured software development, heterogeneous data sources and an ...

Applications of multiple DBMSs and algorithms for time-domain astronomy

, 2019
We present results of using multiple database management systems and algorithms in processing and analyzing time-domain astronomy data. Redis is adopted as our main in-memory spatial data storage for processing time-domain alerts. We also use Google's S2 geometry algorithm and its library to generate light curve products in out time-domain observation ...

Online Classification for Time-Domain Astronomy [PDF]

2013 IEEE 13th International Conference on Data Mining Workshops, 2013
The advent of synoptic sky surveys has spurred the development of techniques for real-time classification of astronomical sources in order to ensure timely follow-up with appropriate instruments. Previous work has focused on algorithm selection or improved light curve representations, and naively convert light curves into structured feature sets ...

Opening the 100-Year Window for Time-Domain Astronomy [PDF]

Proceedings of the International Astronomical Union, 2011
AbstractThe large-scale surveys such as PTF, CRTS and Pan-STARRS-1 that have emerged within the past 5 years or so employ digital databases and modern analysis tools to accentuate research into Time Domain Astronomy (TDA). Preparations are underway for LSST which, in another 6 years, will usher in the second decade of modern TDA.

How Swift is redefining time domain astronomy

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 types of behavior.
