WINTER on S250206dm: A near-infrared search for an electromagnetic counterpart to a gravitational-wave event

Posted by klaurent April 16, 2025MIT

Kavli Affiliate: Robert Simcoe | Summary:We present near-infrared follow-up observations of the International Gravitational Wave Network (IGWN) event S250206dm with the Wide-Field Infrared Transient Explorer (WINTER). WINTER is a near-infrared time-domain survey designed for electromagnetic follow-up of gravitational-wave sources localized to $leq$300 deg$^2$. The instrument’s wide field of view (1.2 deg$^2$), dedicated 1-m robotic telescope, […]

The Discovery of Two Quadruple Star Systems with the Second and Third Shortest Outer Periods

Posted by klaurent April 16, 2025MIT

Kavli Affiliate: Saul Rappaport | Summary:We present the discovery of two quadruple star systems — TIC 285853156 and TIC 392229331 — each consisting of two bound eclipsing binary stars. Among the most compact quadruples known, TIC 392229331 and TIC 285853156 have the second and third shortest outer orbital periods (145 days and 152 days, respectively) […]

Light WIMPs and MeV Gamma-ray Detection with COSI

Posted by klaurent April 16, 2025Tokyo

Kavli Affiliate: Shigeki Matsumoto | Summary:Light weakly interacting massive particles (WIMPs), whose masses are in the sub-GeV scale, have been attracting more attention due to the negative results searching for traditional WIMPs. The light WIMPs are expected to produce gamma rays from annihilation in the MeV energy region. Advancements in technology have opened up possibilities […]

The Cocytos Stream: A Disrupted Globular Cluster from our Last Major Merger?

Posted by klaurent April 16, 2025Stanford

Kavli Affiliate: Risa Wechsler | Summary:The census of stellar streams and dwarf galaxies in the Milky Way provides direct constraints on galaxy formation models and the nature of dark matter. The DESI Milky Way survey — with a footprint of $14,000$ deg$^2$ and a depth of $r<19$ mag — delivers the largest sample of distant […]

Towards High-Voltage Cathodes for Zinc-Ion Batteries: Discovery Pipeline and Material Design Rules

Posted by dbos April 16, 2025April 28, 2025Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Roberta Pascazio, Qian Chen, Haoming Howard Li, Aaron D. Kaplan, Kristin A. Persson | Summary: Efficient energy storage systems are crucial to address the intermittency of renewable energy sources. As multivalent batteries, Zn-ion batteries (ZIBs), while inherently low voltage, offer a promising low cost alternative to […]
