Kavli Affiliate: Max Tegmark | First 5 Authors: Ali Ghorashi, Sachin Vaidya, Ziming Liu, Charlotte Loh, Thomas Christensen | Summary: Topological photonic crystals (PhCs) offer robust, disorder-resistant modes engendered by nontrivial band symmetries, but designing PhCs with prescribed topological band properties remains a challenge due to the complexity involved in mapping the continuous real-space design […]
Kavli Affiliate: John E. Carlstrom | First 5 Authors: Rohan Dahale, Ilje Cho, Kotaro Moriyama, Kaj Wiik, Paul Tiede | Summary: We investigate the origin of the elliptical ring structure observed in the images of the supermassive black hole M87*, aiming to disentangle contributions from gravitational, astrophysical, and imaging effects. Leveraging the enhanced capabilities of […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Sydney Jenkins, Andrew Vanderburg, Ritika Sethi, Sarah Millholland, Joseph E. Rodriguez | Summary: Though missions such as Kepler, K2, and TESS have discovered $>$2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P$lesssim$3 days) orbits. This feature, called the Neptune desert or […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Yacheng Kang, Jin-Ping Zhu, Yu-Han Yang, Ziming Wang, Eleonora Troja | Summary: The recent detections of bright optical/infrared kilonova signals following two long-duration gamma-ray bursts (LGRBs), GRB 211211A and GRB 230307A, have significantly challenged the traditional classification of GRBs. These merger-driven LGRBs may represent a distinct GRB […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Zhaoxuan Liu, John D. Silverman, Emanuele Daddi, Boris S. Kalita, Annagrazia Puglisi | Summary: We present high-resolution and spatially-matched observations with JWST and ALMA of a starburst galaxy (PACS-830) at $z=1.46$. The NIRCam observations mainly trace the stellar light while the CO ($J$=5–4) observations map the […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: Inelastic dark matter models that have two dark matter particles and a massive dark photon can reproduce the observed relic dark matter density without violating cosmological limits. The mass splitting between the two dark […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Viraj Karambelkar, Mansi Kasliwal, Kishalay De, Danielle Frostig, Robert Stein | Summary: We present WNTR23bzdiq/WTP19aalzlk, a slow eruption of an early-asymptotic giant branch (AGB) star in M31 identified by the Wide-field Infrared Transient Explorer (WINTER) near-infrared and the NEOWISE mid-infrared surveyors. This source brightened gradually over […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Xinpeng Wang, Misao Sasaki, Ying-li Zhang, , | Summary: We report a novel mechanism where two families of primordial black holes (PBHs) may form at nearly the same comoving scales but at two different epochs. It is realized in two-stage inflation where a non-inflationary stage is sandwiched […]
