LSST will image 18,000 square degrees of sky about 800 times across six bands over 10 years to a coadded depth of r~27.5, producing a public database of 40 billion objects and 32 trillion observations.
BayeSN analysis of ZTF Type Ia supernovae confirms a ~0.1 mag intrinsic environmental step in standardized brightness that is not explained by differences in dust extinction properties.
In f(T) gravity with Gong-Zhang EoS parametrization, the fitted model shows transient acceleration followed by future deceleration and satisfies thermodynamic consistency.
