Detection of Earth-skimming UHE tau neutrino with the JEM-EUSO detector
The ultra high energy cosmic neutrinos are powerful astrophysical probes for both astrophysical mechanisms of particle acceleration and fundamental interactions. They open a window into the very...
View ArticleOptimized focal and pupil plane masks for vortex coronagraphs on telescopes...
We present methods for optimizing pupil and focal plane optical elements that improve the performance of vortex coronagraphs on telescopes with obstructed or segmented apertures. Phase-only and complex...
View ArticleA Bayesian approach to linear regression in astronomy
Linear regression is common in astronomical analyses. I discuss a Bayesian hierarchical modeling of data with heteroscedastic and possibly correlated measurement errors and intrinsic scatter. The...

We report on the design, construction and operation of a low background x-ray detection line composed of a shielded Micromegas (micromesh gaseous structure) detector of the microbulk technique. The...

Neutron star and supernova matter at densities just below the nuclear matter saturation density is expected to form a lattice of exotic shapes. These so-called nuclear pasta phases are caused by...
View ArticleThe Feasibility of Using Black Widow Pulsars in Pulsar Timing Arrays for...
In the past five years, approximately one third of the 65 pulsars discovered by radio observations of Fermi unassociated sources are black widow pulsars (BWPs). BWPs are binary millisecond pulsars with...
View ArticleDetecting nanohertz gravitational waves with pulsar timing arrays
Complementary to ground-based laser interferometers, pulsar timing array experiments are being carried out to search for nanohertz gravitational waves. Using the world's most powerful radio telescopes,...
View ArticleLeveraging waveform complexity for confident detection of gravitational waves
The recent completion of Advanced LIGO suggests that gravitational waves (GWs) may soon be directly observed. Past searches for gravitational-wave transients have been impacted by transient noise...
View ArticleWide-Band, Low-Frequency Pulse Profiles of 100 Radio Pulsars with LOFAR
LOFAR offers the unique capability of observing pulsars across the 10-240 MHz frequency range with a fractional bandwidth of roughly 50%. This spectral range is well-suited for studying the frequency...
View ArticleThe JCMT Gould Belt Survey: A Quantitative Comparison Between SCUBA-2 Data...
Performing ground-based submillimetre observations is a difficult task as the measurements are subject to absorption and emission from water vapour in the Earth's atmosphere and time variation in...

View ArticleA review of learning vector quantization classifiers [Cross-Listing]
In this work we present a review of the state of the art of Learning Vector Quantization (LVQ) classifiers. A taxonomy is proposed which integrates the most relevant LVQ approaches to date. The main...
View ArticleAn FPGA-based Instrumentation Platform for use at Deep Cryogenic Temperatures...
We describe the operation of a cryogenic instrumentation platform incorporating commercially- available field-programmable gate arrays (FPGAs). The functionality of the FPGAs at temperatures...

The goal of the openStar project is to turn any WWW browser, running on any platform, into a virtual star equipped with parameter knobs and instrumented with output displays that any user can...
View ArticleLocalisation of directional scale-discretised wavelets on the sphere...
Scale-discretised wavelets yield a directional wavelet framework on the sphere where a signal can be probed not only in scale and position but also in orientation. Furthermore, a signal can be...
View Article3D weak lensing with spin wavelets on the ball
We construct the spin flaglet transform, a wavelet transform to analyse spin signals in three dimensions. Spin flaglets can probe signal content localised simultaneously in space and frequency and,...
View ArticleDirectional spin wavelets on the sphere [Cross-Listing]
We construct a directional spin wavelet framework on the sphere by generalising the scalar scale-discretised wavelet transform to signals of arbitrary spin. The resulting framework is the only wavelet...
View ArticleEstimating distances from parallaxes [Replacement]
Astrometric surveys such as Gaia and LSST will measure parallaxes for hundreds of millions of stars. Yet they will not measure a single distance. Rather, a distance must be estimated from a parallax....
