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]
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.

A method for finding anomalous astronomical light curves and their analogues [PDF]
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.

Fast Globally Optimal Catalog Matching using MIQCP
We propose a novel exact method to solve the probabilistic catalog matching problem faster than previously possible. Our new approach uses mixed integer programming and introduces quadratic constraints to shrink the problem by multiple orders of ...

Astronomical observations: a guide for allied researchers
Observational astrophysics uses sophisticated technology to collect and measure electromagnetic and other radiation from beyond the Earth. Modern observatories produce large, complex datasets and extracting the maximum possible information from them ...

Method of Distributing Astronomical Predictions [PDF]
I BEG leave to observe that the very useful method of distributing astronomical predictions over a given geographical area alluded to in NATURE, vol. xiii., page 71, and ascribed there to Mr. W. S. B. Woolhouse, was already proposed by my father, J. J.

On a Method of reproducing Astronomical Photographs [PDF]
PROF. MAX WOLF, in his excellent article on the “Reflector and Portrait Lens in Celestial Photography,” published in your issue of April 22 last, mentions a method of “reproducing nebulous masses” from original negatives, and refers to my reproduction of a photograph of the nebula M. 8, done in collaboration with Mr. Lunt.

We present a study of the potential for convolutional neural networks (CNNs) to enable separation of astrophysical transients from image artifacts, a task known as “real–bogus” classification, without requiring a template-subtracted (or difference) image,
