We present our analysis on new limits of the dark matter (DM) halo consisting of primordial
black holes (PBHs) or massive compact halo objects. We present a search of the first two yr …

If a significant fraction of dark matter is in the form of compact objects, they will cause
microlensing effects in the gravitational wave signals observable by LIGO and Virgo. From …

We present a new quasi-stellar object (QSO) selection algorithm using a Support Vector
Machine, a supervised classification method, on a set of extracted time series features …

We introduce MulensModel, a software package for gravitational microlensing modeling.
The package provides a framework for calculating microlensing model magnification curves …

The development of synoptic sky surveys has led to a massive amount of data for which
resources needed for analysis are beyond human capabilities. In order to process this …

We present a measurement of the microlensing optical depth toward the Galactic bulge
based on 4 years of the OGLE-II survey. We consider only bright sources in the extended red …

Outlier detection is necessary for automated data analysis, with specific applications
spanning almost every domain from financial markets to epidemiology to fraud detection. We …

Red clump giants (RCGs) in the Galactic bulge are approximate standard candles and
hence they can be used as distance indicators. We compute the proper motion dispersions …

We present a new classification method for quasar identification in the EROS-2 and MACHO
data sets based on a boosted version of a random forest classifier. We use a set of variability …

Aims. The EROS-2 project has been designed to search for microlensing events towards
any dense stellar field. The densest parts of the Galactic spiral arms have been monitored to …
