Caltech Builds World’s Largest Neutral-Atom Quantum Computer
Researchers kept more than 6,000 qubits coherent while operating with 99.98% accuracy. Here's why that matters for quantum computing.

Fates of Rotating Supergiants from Stellar Mergers and the Landscape of Transients upon Core-collapse
We present a grid of rotating supergiant models from post-main sequence binary merger products, constructed by the MESA stellar evolution code. We focus on the evolution of these stars until core-collapse, in addition to their rotation, which could influence their mass loss and explosion phenomenology. We find that (i) as in previous studies, larger mass gain by merger favors the production of blue supergiants (BSGs) over red supergiants, and (ii) merger products that end as BSGs at core collap…

Technical Memo: The impact of Nancy Grace Roman Telescope's default image processing on the detectability of moving Solar system objects
The Nancy Grace Roman Telescope is scheduled to launch in 2026 to conduct a wide-field survey of the sky at near-infrared wavelengths. Although Roman is unable to track objects moving at non-sidereal rates, there is recent interest in the potential capability of the telescope to support planetary defense by tracking and characterizing asteroids and comets (Holler et al, 2025, arXiv:2508.14412). However, the standard pipeline image processing scheme that the mission is planning to implement for …

In the next #ag2025goerlitz talk the Co-PI of the #DST2000 radio survey telescope array to be built in #Nevada - https://www.deepsynoptic.org - starting next year introduced the current plan with 1650 6.15-meter telescopes, to be operational in 2029. A German antenna maker is involved - https://schauenburg-international.com/mtex-antenna-technology-entwirft-prototypen-des-dsa-2000-projekts-der-caltech/ - as are German astronomers. The DST-2000 will be the radio counterpart to SPHEREx, Rubin and eROSITA.
