MESA Isochrones and Stellar Tracks (MIST) 0: Methods for the construction of...

I describe a method to transform a set of stellar evolution tracks onto a uniform basis and then interpolate within that basis to construct stellar isochrones. The method accommodates a broad range of...

Xenon Bubble Chambers for Direct Dark Matter Detection

The search for dark matter is one of today's most exciting fields. As bigger detectors are being built to increase their sensitivity, background reduction is an ever more challenging issue. To this...

Shaped Pupil Lyot Coronagraphs: High-Contrast Solutions for Restricted Focal...

Coronagraphs of the apodized pupil and shaped pupil varieties use the Fraunhofer diffraction properties of amplitude masks to create regions of high contrast in the vicinity of a target star. Here we...

A pragmatic Bayesian perspective on correlation analysis: The exoplanetary...

We apply the Bayesian framework to assess the presence of a correlation between two quantities. To do so, we estimate the probability distribution of the parameter of interest, $\rho$, characterizing...

Repeatability and Accuracy of Exoplanet Eclipse Depths Measured with...

We examine the repeatability, reliability, and accuracy of differential exoplanet eclipse depth measurements made using the InfraRed Array Camera (IRAC) on the Spitzer Space Telescope during the...

Fast Radio Transient searches with UTMOST at 843 MHz [Replacement]

We report the first radio interferometric search at 843 MHz for fast transients, particularly Fast Radio Bursts (FRBs). The recently recommissioned Swinburne University of Technology's digital backend...

Interferometric observation of microlensing events

Interferometric observations of microlensing events have the potential to provide unique constraints on the physical properties of the lensing systems. In this work, we first present a formalism that...

Model-Coupled Autoencoder for Time Series Visualisation

We present an approach for the visualisation of a set of time series that combines an echo state network with an autoencoder. For each time series in the dataset we train an echo state network, using a...

Hard X-ray irradiation of cosmic silicate analogs: structural evolution and...

Protoplanetary disks, interstellar clouds, and active galactic nuclei, contain X-ray dominated regions. X-rays interact with the dust and gas present in such environments. While a few laboratory X-ray...

Multichroic TES Bolometers and Galaxy Cluster Mass Scaling Relations with the...

The South Pole Telescope (SPT) is a high-resolution microwave-frequency telescope designed to observe the Cosmic Microwave Background (CMB). To date, two cameras have been installed on the SPT to...

The Advanced LIGO Input Optics [Cross-Listing]

The Advanced LIGO gravitational wave detectors are nearing their design sensitivity and should begin taking meaningful astrophysical data in the fall of 2015. These resonant optical interferometers...

LOFAR facet calibration

LOFAR, the Low-Frequency Array, is a powerful new radio telescope operating between 10 and 240 MHz. LOFAR allows detailed sensitive high-resolution studies of the low-frequency radio sky. At the same...

That’s How We Roll: The NASA K2 Mission Science Products and Their...

NASA's exoplanet Discovery mission Kepler was reconstituted as the K2 mission a year after the failure of the 2nd of Kepler's 4 reaction wheels in May 2013. The new spacecraft pointing method now gives...

The Theoretical Astrophysical Observatory: Cloud-Based Mock Galaxy Catalogues...

We introduce the Theoretical Astrophysical Observatory (TAO), an online virtual laboratory that houses mock observations of galaxy survey data. Such mocks have become an integral part of the modern...

Real-time detection of transients in OGLE-IV with application of machine...

The current bottleneck of transient detection in most surveys is the problem of rejecting numerous artifacts from detected candidates. We present a triple-stage hierarchical machine learning system for...
