The Zwicky Transient Facility: System Overview, Performance, and First Results
read the original abstract
The Zwicky Transient Facility (ZTF) is a new optical time-domain survey that uses the Palomar 48-inch Schmidt telescope. A custom-built wide-field camera provides a 47 deg$^2$ field of view and 8 second readout time, yielding more than an order of magnitude improvement in survey speed relative to its predecessor survey, the Palomar Transient Factory (PTF). We describe the design and implementation of the camera and observing system. The ZTF data system at the Infrared Processing and Analysis Center provides near-real-time reduction to identify moving and varying objects. We outline the analysis pipelines, data products, and associated archive. Finally, we present on-sky performance analysis and first scientific results from commissioning and the early survey. ZTF's public alert stream will serve as a useful precursor for that of the Large Synoptic Survey Telescope.

On the Gamma-ray Efficiency of Superluminous Supernovae: Potential Detections and Population-Level Constraints
No significant GeV emission from 223 SLSNe constrains GeV-to-optical efficiency to η < 1.3×10^{-3}, with <0.7% of events allowed above 10^{-2}; SN 2017egm shows a ~4σ excess favoring magnetar origin while SN 2018bsz does not.

DESI DR2 Results II: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints
DESI DR2 BAO data exhibits 2.3 sigma tension with CMB in Lambda-CDM but prefers evolving dark energy (w0 > -1, wa < 0) at 3.1 sigma with CMB and 2.8-4.2 sigma when including supernovae.

Pre-localization of Massive Black Hole Binaries in the Millihertz Band
A neural spline flow pipeline performs amortized inference on millihertz MBHB signals, delivering ~20 deg² pre-merger sky localizations in ~1 minute while matching PTMCMC sky modes and parameter uncertainties.

Optical transients from non-explosive double white-dwarf mergers: the case of a central neutron star remnant
Non-explosive DWD mergers leaving NS remnants produce optical transients detectable by LSST out to 30-820 Mpc with rates 10²-10⁶ yr⁻¹ depending on log D, though survey cadence restricts reliable detections to log D = ...

Finding Strongly Lensed Supernovae from Blended Light Curves
A model-independent method fits blended supernova light curves as superpositions of two time-delayed components and finds only one candidate above a 12-day delay threshold in 445 ZTF Type Ia supernovae, for a 0.22% fa...

The Recurrent Nova Population in M31
M31 hosts at least 20 recurrent novae with 79 total eruptions; half recur faster than the shortest Galactic example, while light-curve and spatial properties match the Milky Way population.
