OGLE-ing the Magellanic System: Cepheids in the Bridge
  We present a detailed analysis of Magellanic Bridge Cepheid sample
constructed using the OGLE Collection of Variable Stars. Our updated Bridge
sample contains 10 classical and 13 anomalous Cepheids. We calculate their
individual distances using optical period--Wesenheit relations and construct
three-dimensional maps. Classical Cepheids on-sky locations match very well
neutral hydrogen and young stars distributions, thus they add to the overall
Bridge young population. In three dimensions, eight out of ten classical
Cepheids form a bridge-like connection between the Magellanic Clouds. The other
two are located slightly farther and may constitute the Counter Bridge. We
estimate ages of our Cepheids to be less than 300 Myr for five up to eight out
of ten, depending on whether the rotation is included. This is in agreement
with a scenario where these stars were formed in-situ after the last encounter
of the Magellanic Clouds. Cepheids' proper motions reveal that they are moving
away from both Large and Small Magellanic Cloud. Anomalous Cepheids are more
spread than classical Cepheids in both two and three dimensions. Even though,
they form a rather smooth connection between the Clouds. However, this
connection does not seem to be bridge-like, as there are many outliers around
both Magellanic Clouds.
