Extreme Stellar Death and Galaxy Feedback at z = 2: A Rest-frame Ultraviolet Characterization of the Strongly Lensed Superluminous Supernova 2025wny

Posted by klaurent Cambridge

Kavli Affiliate: Kaisey Mandel | Summary:We present photometric and spectroscopic follow-up observations of the strongly-lensed H-poor superluminous supernova (SLSN) 2025wny at $z = 2.0155$. We use integral-field Keck-II/KCWI spectroscopy to obtain rest-frame ultraviolet spectra spanning $11$ to $61$ days after maximum light. We use Pan-STARRS photometry to constrain the brightest image’s magnification, finding $μ_A=19.4pm1.6$, a […]

HD 715 b, a Warm Jupiter Orbiting a Massive Subgiant Discovered from a Single TESS Transit

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | Summary:Transiting Warm Jupiters orbiting bright stars are scarcely known, but a substantial number of these planets have been uncovered by the TESS mission. In this work we report the discovery and confirmation of a transiting Warm Jupiter orbiting the bright ($V$ = 8.70) subgiant star HD 715 (TOI-6893). HD 715 […]

Formation of Supermassive Black Hole Seeds from Vacuum-Dependent Thermal Dark Matter

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Kawasaki | Summary:The origin of supermassive black holes, especially those already present at high redshift, remains an open problem. We propose that their seeds are primordial black holes formed from rare overdense regions of conventional thermal DM. A spectator scalar with two degenerate vacua gives the DM different masses, and hence different […]

Sparse qubit operation in a 6$times$6 quantum dot array

Posted by klaurent Delft

Kavli Affiliate: Menno Veldhorst | Summary:Fault-tolerant quantum computation requires increasing the qubit count while maintaining high performance and connectivity. Semiconductor qubits have demonstrated high-fidelity operation, but growing the system size at sufficient connectivity remains challenging, such that scaling mainly occurred in one spatial direction to preserve access for control lines in the other. Here, we […]

EigenDEXplore: Structured Exploration for Dexterous Manipulation with Human Priors

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:Dexterous manipulation poses a challenging high-dimensional optimization problem, as useful behaviors require coordinated motion across many hand joints. In reinforcement learning (RL) and sampling-based trajectory optimization, exploration commonly relies on independent robot joint perturbations, making coordinated behaviors difficult to discover. Prior work reduces this search space for grasp learning using low-dimensional […]

A spatially resolved view of Fast Radio Burst host metallicities with Integral-field Spectroscopy

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi Masui | Summary:Magnetar sources are the leading theory for Fast Radio Burst (FRB) progenitors. If magnetars are indeed the dominant sources, we may thus expect any metallicity preference for magnetar formation to be reflected in the FRB site in host galaxies. Here, we leverage Integral Field Unit (IFU) spectroscopy to spatially resolve […]
