CURRENT PROJECT
Look for evidence of Fuzzy Dark Matter
CHESHIRE CAT
Cheshire cat is nickname of SDSS J1038+4849, it is a galaxy cluster that has not 1 BCG(Brightest Cluster Galaxy) but 2 BCGs, which assemble both eyes.
This cluster is likely to be a line of sight merger (Irwin et al., 2015) between two groups of galaxy dominated by left and right eye respectively.
This cluster is at z=0.43, and has at least 4 lensed arcs, these four arcs provide a prime site for determining nature of dark matter as Fuzzy Dark Matter would give rise to fluctuation of observed magnification compare to model.
​
ABELL 2218
Abell 2218 has a lensed arc to the top left which has peculiar flux ratio in its counter images. This could be caused by Fuzzy Dark Matter but cannot tell unless we create an accurate lens model.
I already have several version of models which would be uploaded later.
However this project is currently on hiatus due to possibly incorrect red-shift determination in previous works by different groups
