Gravitational Microlensing [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractGravitational microlensing is a well established and unique field of time-domain astrophysics. For two decades microlensing surveys have been regularly observing millions of stars to detect elusive events that follow a characteristic Paczyński lightcurve.

Astrophysical implications of gravitational microlensing of gravitational waves [PDF]
Astronomy & Astrophysics, 2001 Astrophysical implications of gravitational microlensing of gravitational waves emitted by rotating neutron stars (NSs) are investigated. In particular, attention is focused on the following situations: i) NSs in the galactic bulge lensed by a central black hole of $2.6\times 10^6 M_{\odot}$ or by stars and MACHOs distributed in the galactic bulge ...

Constraints on compact dark matter from gravitational wave microlensing [PDF]
, 2022 If a significant fraction of dark matter is in the form of compact objects, they will cause microlensing effects in the gravitational wave (GW) signals observable by LIGO and Virgo.

Gravitational Microlensing of Extended Objects [PDF]
, 1998 Gravitational microlensing is an important tool in the search for Galactic dark matter. This thesis investigates how microlensing can be used to infer astrophysically interesting information about the structure of extended objects, as well as the ...

Magnetic Manipulation of Superparamagnetic Colloids in Droplet‐Based Optical Devices
Advanced Optical Materials, Volume 11, Issue 21, November 6, 2023., 2023 Colloidal particles inside droplets are assembled and manipulated using an external magnetic field to create magnetically controlled active microlenses and optical shutters. Using monodisperse microfluidic droplets, the assembly of particles into 2D clusters is systematically investigated and exploited to manipulate light.

Ultra wide‐field infrared astronomy in Antarctica
Astronomische Nachrichten, Volume 344, Issue 8-9, October-November 2023., 2023 The science enabled by the deep and high‐cadence survey that will be performed by the Vera Rubin Observatory has led to an increase of survey and follow‐up capabilities around the world. The infrared, has however, not match this growth due to the challenges caused by the atmospheric and the cost of large detector arrays.

Characteristic Features of Gravitational Wave Lensing as Probe of Lens Mass Model
Annalen der Physik, Volume 535, Issue 6, June 2023., 2023 The gravitational lensing of gravitational waves is an expanding field in astronomy and cosmology. It might contribute to solving many different issue in these fields. To exploit its potential, first of all, one needs to recognize and model a gravitational wave event properly.

The road toward imaging a black hole: A personal perspective
Natural Sciences, Volume 2, Issue 4, October 2022., 2022 The article describes the authors personal journey towards developig the Event Horizon Telescope and the first image of a black hole. Left: predcition made by the author and collaborators proposing the black hole imaging in 2000. Right: the two images observed and published by the Event Horizon Telescope in 2019 and 2022.

Identifying interesting planetary systems for future X‐ray observations
Astronomische Nachrichten, Volume 343, Issue 4, May 2022., 2022 Abstract X‐ray observations of star–planet systems are important to grow our understanding of exoplanets; these observations allow for studies of photoevaporation of the exoplanetary atmosphere, and in some cases even estimations of the size of the outer planetary atmosphere.
