A Multilevel Scheduling Framework for Distributed Time-domain Large-area Sky Survey Telescope Array
The Astronomical Journal, 2023 Telescope arrays are receiving increasing attention due to their promise of higher resource utilization, greater sky survey area, and higher frequency of full space-time monitoring than single telescopes.

Solving the Traveling Telescope Problem with Mixed-integer Linear Programming
The Astronomical Journal, 2023 The size and complexity of modern astronomical surveys has grown to the point where, in many cases, traditional human scheduling of observations are tedious at best and impractical at worst.

Astronomical observatory site selection using fuzzy AHP and BWM methods [PDF]
Serbian Astronomical Journal, 2023 Establishing an observatory often involves complex decisions, such as choosing a site based on multiple conflicting criteria. In this study, we develop a multi-criteria decision analysis process by combining Geographic Information System (GIS) analysis ...

The Astrophysical Journal Supplement Series, 2023 We investigate the uncertainties of fitted X-ray model parameters and fluxes for relatively faint Chandra ACIS-I source spectra. Monte Carlo (MC) simulations are employed to construct a large set of 150,000 fake X-ray spectra in the low photon count ...

Methods of Astronomical Navigation [PDF]
Journal of Navigation, 1955 I think the Institute is doing a grand job in this matter of getting to the bottom of what actually happens at sea. I give a personal ‘shabash’ to D. H. Sadler & Co. for the new Abridged Nautical Almanac, and to S. M. Burton for the first-ever really practical manual and tables, but I am now completely ‘sold’ on H.D.

The 5.25 & 5.7 $\mu$m Astronomical Polycyclic Aromatic Hydrocarbon Emission Features [PDF]
, 2008 Astronomical mid-IR spectra show two minor PAH features at 5.25 and 5.7 $\mu$m (1905 and 1754 cm$^{\rm - 1}$) that hitherto have been little studied, but contain information about the astronomical PAH population that complements that of the major ...

A method for finding anomalous astronomical light curves and their analogues [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Our understanding of the Universe has profited from deliberate targeted studies of known phenomena, as well as from serendipitous unexpected discoveries, such as the discovery of a complex variability pattern in the direction of KIC 8462852 (Boyajian’s star). Upcoming surveys such as the Vera C.
