Unlike most other planet-detection techniques, gravitational microlensing does not rely on
detection of photons from either the host or the planet. Rather, planets are discovered by …

Gravitational lensing has developed into one of the most powerful tools for the analysis of
the dark universe. This review summarizes the theory of gravitational lensing, its main …

The Advanced LIGO [1] and Advanced Virgo [2] detectors have made numerous detections
of gravitational waves (GWs), to date consisting of short-duration (transient) GWs emitted …

We present both the technical overview and main science drivers of the fourth phase of the
Optical Gravitational Lensing Experiment (hereafter OGLE-IV). OGLE-IV is currently one of …

Gravitational lensing occurs when a massive object bends spacetime in a way that focuses
light rays toward an observer (see Bartelmann 2010, for a review). Lensing observations are …

The Korea Microlensing Telescope Network (KMTNet) is a wide-field photometric system
installed by the Korea Astronomy and Space Science Institute (KASI). Here, we present the …

Context. Searching for planets around stars with different masses helps us to assess the
outcome of planetary formation for different initial conditions. The low-mass M dwarfs are …

Future surveys for transiting extrasolar planets are expected to detect hundreds of jovian-
mass planets and tens of terrestrial-mass planets. For many of these newly discovered …

We have produced a new conformal map of the universe illustrating recent discoveries,
ranging from Kuiper Belt objects in the solar system to the galaxies and quasars from the …

In the favoured core-accretion model of formation of planetary systems, solid planetesimals
accumulate to build up planetary cores, which then accrete nebular gas if they are …
