The future of high-resolution UV spectroscopy: Science with a UV Échelle spectrograph on the Habitable Worlds Observatory, or a dedicated mission

Posted by klaurent September 8, 2026Chicago

Kavli Affiliate: Hsiaowen Chen |Summary:High-resolution UV spectroscopy serves a diversity of science cases, from small bodies to planets, stars, and galaxies, but is currently limited to the Hubble Space Telescope and bright targets. Major advances require increasing sensitivity by at least one order of magnitude. Here we present the UV science cases for PEGASUS (Planets, […]

Near-Horizon Tidal Disruption Events

Posted by klaurent September 8, 2026Peking

Kavli Affiliate: Xian Chen| Summary: Tidal disruption events (TDEs) offer a unique dynamical probe of the spacetime geometry around supermassive black holes (SMBHs). While conventional TDEs occur around SMBHs of $M_bullet sim 10^6 – 10^7 M_odot$, where stars are disrupted far from the event horizon, here we identify a special class of TDEs around rapidly […]

The Roman eXtreme Deep Field (RXDF)

Posted by klaurent September 8, 2026Tokyo

Kavli Affiliate: John Silverman | Summary:The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in Cycles 1 and 2. It has been allocated 386.41 hours to carry out an imaging survey to AB = 30 mag […]

Signatures of nodal superconductivity in stoichiometric FeTe

Posted by klaurent September 8, 2026Cornell

Kavli Affiliate: Katja C. Nowack | Summary:Superconductivity in stoichiometric FeTe opens access to the FeTe endpoint of the Fe(Se,Te) phase diagram, yet the nature of its superconducting pairing state remains unresolved. In this work, we combine scanning superconducting quantum interference device (SQUID) microscopy, electrical transport, scanning tunneling microscopy and spectroscopy (STM/S), and mean-field calculations to […]
