Searching for Lensing Candidates

[ Poster ]

We investigate close binary point sources to look for possible lensing objects. We first searched for double point sources that are close to each other with angular separations between 2 and 15 arcsec from Pan-STARRS PS1 catalog. We only selected pair sources that have similar colors that derived from five filters of Pan-STARRS. We found that there is a slight enhancement of pair sources with similar magnitudes in our sample; this suggests a possible physical correlation between these pair sources. We consider these pairs with similar magnitudes as candidates of lensing sources and further investigate their light curves. We show our results in this poster.
