Interferometry in the era of time-domain astronomy

Experimental Astronomy, 2018
The physical nature of time variable objects is often inferred from photometric light-curves and spectroscopic variations. Long-baseline optical interferometry has the power to resolve the spatial structure of time variable sources directly in order to measure their physical properties and test the physics of the underlying models.

DASCH for Days to Decades Time Domain Astronomy

, 2017
The Digital Access to a Sky Century @ Harvard (DASCH) project has been underway for the past decade to digitize and fully reduce (photometry and astrometry) the ~450,000 glass plate images (not spectra) of the full sky taken by some ~30 Harvard telescopes from 1885 to 1992.

Development of a fast readout system of a CMOS image sensor for the time-domain astronomy

Astronomical Telescopes + Instrumentation, 2020
In this paper we report on development of an FPGA-based fast readout system of a CMOS image sensor for the future satellite mission HiZ-GUNDAM observing gamma-ray bursts (GRBs) in the 0.4–4 keV band.

Design and implementation of a prototype of Antarctic optical telescope array for time domain astronomy based on drift-scan CCD technology

SCIENTIA SINICA Physica, Mechanica & Astronomica
Rapid sky survey using a large field-of-view telescope is an important method for time-domain astronomy. With many continuous nights in polar night season, the Antarctic region is an ideal place for short-term time-domain astronomy observation.

Challenges and Opportunities for Machine Learning in Time-Domain Astronomy

Proceedings of the International Astronomical Union, 2017
AbstractThe recent spectacular progress in machine learning and artificial intelligence opens up exciting opportunities for time-domain and transient astronomy. This talk outlined the fundamental challenges that we will need to overcome in order to realise that potential, from discovering completely new classes to fully-automated follow-up campaigns.
