Spectroscopic measurements confirm a tight 6D phase-space clump of four RGB stars as part of the distant southern spur of the Sagittarius stream, likely stripped from Sagittarius's halo in the earliest interaction phases.

IY Lyr is a thick-disk RRc star with a 1.37 solar-mass companion most likely a neutron star in a 3.94-year eccentric orbit, confirmed by photometry, spectroscopy, and astrometry.
A large sample of blue horizontal-branch stars reveals that the Milky Way halo anisotropy increases from the center, stays radially dominated after removing merger debris, and shows older stars on colder, less radial orbits in the inner regions.
Pilot verification using Rubin early alerts confirms 32 of 40 RR Lyrae candidates from prior catalogs as real while identifying 20% non-RR Lyrae contaminants including AGN and eclipsing binaries.
ZTF high-cadence data shows RR Lyrae stars and flaring sources can mimic UV transients, with pre-existing ML catalogs offering a concrete mitigation approach.
