The Importance of Computation in Astronomy Education [Cross-Listing]
Computational skills are required across all astronomy disciplines. Many students enter degree programs without sufficient skills to solve computational problems in their core classes or contribute...
View ArticleBolidozor – Distributed radio meteor detection system
Most of the meteor radioastronomical radars are backscatter radars which cover only a small area of the atmosphere. Therefore a daytime meteor flux models are based on sparse data collected by only a...
View ArticleCalibration of quasi-static aberrations in exoplanet direct-imaging...
Warm or massive gas giant planets, brown dwarfs, and debris disks around nearby stars are now routinely observed by dedicated high-contrast imaging instruments on large, ground-based observatories....
View ArticleDetecting dark matter waves with precision measurement tools [Replacement]
Virialized Ultra-Light Fields (VULFs) while being viable cold dark matter candidates can also solve the standard model hierarchy problem. Direct searches for VULFs due to their non-particle nature...
View ArticleCalibration Requirements for Detecting the 21 cm Epoch of Reionization Power...
21 cm Epoch of Reionization observations promise to transform our understanding of galaxy formation, but these observations are impossible without unprecedented levels of instrument calibration. We...
View ArticleA two-component model for fitting light-curves of core-collapse supernovae...
We present an improved version of a light curve model, which is able to estimate the physical properties of different types of core-collapse supernovae having double-peaked light curves, in a quick and...
View ArticleEstimating the Mass of the Local Group using Machine Learning Applied to...
We revisit the estimation of the combined mass of the Milky Way and Andromeda (M31), which dominate the mass of the Local Group. We make use of an ensemble of 30,190 halo pairs from the Small MultiDark...
View ArticleFalse periodicities in quasar time-domain surveys
There have recently been several reports of apparently periodic variations in the light curves of quasars, e.g. PG 1302-102 by Graham et al. (2015a). Any quasar showing periodic oscillations in...

Despite the significant experimental effort made in the last decades, the origin of the ultra-high energy cosmic rays is still largely unknown. Key astrophysical information to identify where these...
View ArticleOne-Port Direct/Reverse Method for Characterizing VNA Calibration Standards
This paper introduces a one-port method for estimating model parameters of VNA calibration standards. The method involves measuring the standards through an asymmetrical passive network connected in...
View ArticleHidden Markov model tracking of continuous gravitational waves from a neutron...
Gravitational wave searches for continuous-wave signals from neutron stars are especially challenging when the star's spin frequency is unknown a priori from electromagnetic observations and wanders...
View ArticleA moving mesh unstaggered constrained transport scheme for magnetohydrodynamics
We present a constrained transport (CT) algorithm for solving the 3D ideal magnetohydrodynamic (MHD) equations on a moving mesh, which maintains the divergence-free condition on the magnetic field to...

We have been conducting a survey for distant solar system objects beyond the Kuiper Belt edge (~50 AU) with new wide-field cameras on the Subaru 8 meter and CTIO 4 meter telescopes. We are interested...
View Articlengravs: Distinct gravitational interactions in GADGET-2 [Replacement]
We discuss an extension of the massively parallel cosmological simulation code GADGET-2, which now enables investigation of multiple and distinct gravitational force laws, provided they are dominated...
View ArticleThe self-coherent camera as a focal plane fine phasing sensor
Direct imaging of Earth-like exoplanets requires high contrast imaging capability and high angular resolution. Primary mirror segmentation is a key technological solution for large-aperture telescopes...
View ArticleEngineering and Science Highlights of the KAT-7 Radio Telescope
The construction of the KAT-7 array in the Karoo region of the Northern Cape in South Africa was intended primarily as an engineering prototype for technologies and techniques applicable to the MeerKAT...
