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.

Trend filtering – I. A modern statistical tool for time-domain astronomy and astronomical spectroscopy [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The problem of denoising a 1D signal possessing varying degrees of smoothness is ubiquitous in time-domain astronomy and astronomical spectroscopy. For example, in the time domain, an astronomical object may exhibit a smoothly varying intensity that is

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

The Astrophysical Journal Letters, 2023 We report the discovery of a faint optical tidal disruption event (TDE) in the nearby star-forming galaxy NGC 3799. Identification of the TDE is based on its position at the galaxy nucleus, a light curve declining as t ^−5/3 , a blue continuum with an ...

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.

High-speed readout system of X-ray CMOS image sensor for time domain astronomy [PDF]
Journal of InstrumentationWe developed an FPGA-based high-speed readout system for a complementary metal-oxide-semiconductor (CMOS) image sensor to observe soft X-ray transients in future satellite missions, such as HiZ-GUNDAM.

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,
