PSR B0329+54: Statistics of Substructure Discovered within the Scattering...

We discovered fine-scale structure within the scattering disk of PSR B0329+54 in observations with the RadioAstron ground-space radio interferometer. Here, we describe this phenomenon, characterize it...

A Radio Detection Survey of Narrow-Line Seyfert 1 Galaxies using...

We conducted a high-sensitivity radio detection survey for forty narrow-line Seyfert 1 (NLS1) galaxies using very-long-baseline interferometry (VLBI) at 22 GHz through phase-referencing long-time...

FOTOMCAp: a new quasi-automatic code for high-precision photometry

The search for Earth-like planets using the transit technique has encouraged the development of strategies to obtain light curves with increasingly precision. In this context we developed the FOTOMCAp...

Detecting compact galactic binaries using a hybrid swarm-based algorithm...

Compact binaries in our galaxy are expected to be one of the main sources of gravitational waves for the future eLISA mission. During the mission lifetime, many thousands of galactic binaries should be...

RadioLensfit: Bayesian weak lensing measurement in the visibility domain...

Observationally, weak lensing has been served so far by optical surveys due to the much larger number densities of background galaxies achieved, which is typically by two to three orders of magnitude...
