Directional Tests of the Cosmic Distance Duality Relation using Pantheon+ and BAO

Pushty Shrimankar, Gopal Kashyap

We present a model-independent test of anisotropy in the cosmic distance duality relation (CDDR), $D_L=(1+z{)}^2{D}_A$, using the Pantheon+ type Ia supernova sample and baryon acousti…
