Novel directed search strategy to detect continuous gravitational waves from...
We describe a novel, very fast and robust, directed search incoherent method for periodic gravitational waves (GWs) from neutron stars in binary systems. As directed search, we assume the source sky...

The Large Binocular Telescope Interferometer uses a near-infrared camera to measure the optical path length variations between the two AO-corrected apertures and provide high-angular resolution...
View ArticleExploring the Sensitivity of Next Generation Gravitational Wave Detectors
With the development of extremely sensitive ground-based gravitational wave detectors, and the recent detection of gravitational waves by LIGO, extensive theoretical work is going into understanding...

View ArticleObservational biases for transiting planets [Replacement]
Observational biases distort our view of nature, such that the patterns we see within a surveyed population of interest are often unrepresentative of the truth we seek. Transiting planets currently...

We investigate the radial velocity (RV) variability and spectroscopic binarity of 19 Galactic long-period ($P_{\rm{puls}} \gtrsim 10$ d) classical Cepheid variable stars whose trigonometric parallaxes...
View ArticleA balance for Dark Matter bound states
Massive particles with self interactions of the order of 0.2 barn/GeV are intriguing Dark Matter candidates from an astrophysical point of view. Direct detection searches for very massive particles,...
View ArticleHigh order dark wavefront sensing simulations
Dark wavefront sensing takes shape following quantum mechanics concepts in which one is able to "see" an object in one path of a two-arm interferometer using an as low as desired amount of light...
View ArticleDark tip-tilt sensing
Dark wavefront sensing in its simplest and more crude form is a quad-cell with a round spot of dark ink acting as occulting disk at the center. This sensor exhibits fainter limiting magnitude than a...
