| Description | Next generation microlensing simulations have been employed to verify the accuracy of current model of Galactic structure, finding good agreement with some discrepancy in the Galactic bulge/bar region. Similar microlensing simulations have been used to predict the amount of Earth and Jupiter mass free-floating planets (FFPs) which a joint survey by the upcoming Euclid and NGRST space telescopes could detect. These numbers specifically refer to FFPs for which we could reasonably calculate a planetary mass and hence provide bounds on the occurrence rates of FFPs in our Galaxy. An exoplanet has been discovered from Kepler's K2C9 microlensing campaign, which is of particular importance as this has been the first microlensing exoplanet discovery from a space based observatory. Ground based data was later used to provide extra information about the exoplanet. This discovery proves that space based microlensing surveys such as by Euclid and NGRST are feasible. |
| Exploitation Route | The mabuls-2 microlensing tool can be used by the research community and is available at http://www.mabuls.net/ |
| Sectors | Education |
| Title | Mabuls-2 |
| Description | Allows the user to generate gravitational microlensing parameter maps for optical depth, micolensing timescale, rate per source star and rate per square degree, of the galaxy centred around (l,b) = (0,0) in user specified Johnson-Cousins wavelength bands. |
| Type Of Technology | Webtool/Application |
| Year Produced | 2020 |
| Impact | As the software has only been online since mid 2020, there is no published work utilising its output, although there is ongoing research currently using it. |
