  • OGLE microlensing events in Galactic Bulge

    We present the Catalog of microlensing events detected toward the Galactic bulge in three observing seasons, 1997-1999, during the OGLE-II microlensing survey. The search for...
  • Candidate lensed SNe Ia in the ZTF archive

    Gravitationally lensed type Ia supernovae (glSNe Ia) are unique astronomical tools that can be used to study cosmological parameters, distributions of dark matter, the...
  • Powerful lens galaxy cluster PLCK G287.0+32.9

    We present a new high-precision strong-lensing model of PLCK G287.0+32.9, a massive lens galaxy cluster at z=0.383, with the aim of obtaining an accurate estimation of its...
  • Lensed quasar eRASS1 J050129.5-073309

    We report the discovery and spectroscopic identification of the bright doubly lensed quasar eRASS1 J050129.5-073309 at redshift z=2.47, selected from the first all-sky survey of...
  • MG B2016+112 radio images

    In this paper, we exploit the gravitational lensing effect to detect proper motion in the highly magnified gravitationally lensed source MG B2016+112. We find positional shifts...
  • R-band light curves of RX J1131-1231

    We present the results from nine years of optically monitoring the gravitationally lensed z_QSO_=0.658 quasar RX J1131-1231. The R-band light curves of the four individual...
  • Microlensing maps for a cusp configuration

    We provide the microlensing maps generated to study microlensing in the mid-infrared range for a cusp-configuration lensed AGN. The maps provided correspond to images which are...
  • Abundances of microlensed stars in the Bulge

    We perform a detailed elemental abundance analysis of dwarf stars in the Galactic bulge, based on high-resolution spectra that were obtained while the stars were optically...
  • EROS-2 microlensing parameters

    We present a new EROS-2 measurement of the microlensing optical depth toward the Galactic Bulge. Light curves of 5.6x10^6^ clump-giant stars distributed over 66deg^2^ of the...
