Investigating the Observational Progenitor Mass Gap in the White Dwarf Initial-Final Mass Relation. I. Cluster Census and Characterization of the First White Dwarfs in the Gap

Posted by klaurent July 27, 2026Chicago

Kavli Affiliate: David W. Miller | Summary:In recent years, Gaia has been the primary driver of the expansion of the white dwarf (WD) initial-final mass relation (IFMR) in open clusters. The increased sample size has highlighted a pronounced observational gap at progenitor masses of $simeq2$–$2.7,M_odot$, with no spectroscopically confirmed cluster-member WDs in this range. Analysis […]

JWST/NIRCam Imaging of Young Stellar Objects. IV. Detailed Imaging of the Protoplanetary Disk around TW Hya

Posted by klaurent July 27, 2026Peking

Kavli Affiliate: Ruobing Dong | Summary:As the nearest protoplanetary disk to Earth ($d = 60.14$ pc), TW Hya is one of the most studied protoplanetary disks and a critical benchmark for testing planet formation theories. We present high-contrast coronagraphic imaging of the TW Hya disk from JWST/NIRCam across four filters (F187N, F200W, F356W, and F444W). […]

Harnessing X-ray Absorption Spectroscopy Data through Multimodal Mining of Battery Literature

Posted by klaurent July 26, 2026Berkeley

Kavli Affiliate: Gerbrand Ceder| Summary:X-ray absorption spectroscopy (XAS) is central to understanding the local electronic and atomic structure of materials, yet most published spectra remain inaccessible to data-driven analysis because they are embedded in figures and described through fragmented textual context in the literature. Here, we use multimodal (image and text) literature mining to transform […]

Bias-preserving cat-cat CNOT gate via vacuum-conditional beam-splitter

Posted by klaurent July 24, 2026Caltech

Kavli Affiliate: Oskar Painter | Summary:Cat qubits can exhibit strong noise bias due to their exponentially enhanced bit-flip times and only polynomially reduced phase-flip times with increasing photon number, which makes them attractive candidates for hardware-efficient quantum error correction. However, it is difficult to maintain this strong noise bias in logical operations such as CNOT […]

Payne4GAIN: NLTE Corrections for Red Giants in Milky Way Mapper using H-Band Neural Network Emulators

Posted by klaurent July 24, 2026July 27, 2026Chicago, This Week: Astrophysics

Kavli Affiliate: Alexander Ji | Summary:The majority of spectroscopic surveys assume local thermodynamic equilibrium (LTE) during the modeling of stellar spectra. This assumption begins to break down for luminous stars, like the red giants targeted by SDSS-V’s Milky Way Mapper Survey in its Galactic Genesis program. In this work, we present non-LTE (NLTE) abundances for […]

Optical design of VIPER: a high-resolution multimode fiber-fed VIPA spectrograph for characterizing exoplanet atmospheric escape

Posted by klaurent July 24, 2026July 27, 2026Harvard, This Week: Nanoscience

Kavli Affiliate: David Charbonneau | Summary:We present the optical design of VIPER: a high-resolution, multimode fiber-fed, narrowband, cross-dispersed, seeing-limited spectrograph based on a Virtually Imaged Phased Array (VIPA), a spectral disperser that provides higher dispersion and a more compact form factor than conventional diffraction gratings. VIPER is specifically designed to probe exoplanet atmospheric escape through […]

A Kalman Filter Based Approach to NV Diamond Data Fusion For Improved Temperature Sensing

Posted by klaurent July 24, 2026July 27, 2026Stanford, This Week: Astrophysics

Kavli Affiliate: Zeeshan Ahmed | Summary:Nitrogen-vacancy (NV) centers in diamond have been demonstrated to enable highly sensitive temperature measurements using multiple modalities. Standalone optically detected magnetic resonance (ODMR) provides robust temperature estimates, albeit with high latency, whereas all-optical measurements provide millisecond resolution but suffer from poorer long-term accuracy. In this work, we demonstrate a hot-start […]

ANDES, the high-resolution spectrograph for the ELT: design and performance analysis of the YJH spectrograph

Posted by klaurent July 24, 2026July 27, 2026Cambridge, This Week: Astrophysics

Kavli Affiliate: Roberto Maiolino | Summary:The ArmazoNes high Dispersion Echelle Spectrograph (ANDES) is a powerful second-generation high-resolution spectroscopic instrument for the Extremely Large Telescope (ELT). The UBV, RIZ, and YJH modules comprise fibre-fed spectrographs of the ANDES baseline design and will offer continuous wavelength coverage of 0.35-1.8 $μ$m, with the addition of a K-band channel […]

Self-adjoint extensions of $k$-photon light-matter Hamiltonians

Posted by klaurent July 24, 2026July 27, 2026Berkeley, This Week: Nanoscience

Kavli Affiliate: Felix Fischer | Summary:Multiphoton light-matter interactions, in which a bosonic mode exchanges $k$ excitations at a time with a quantum system, are a source of genuine nonlinearity in quantum optics and are increasingly accessible experimentally. Here we study the class of operators $H = H_rm matotimes I + Iotimesωa^ast a + Σotimes(a^ast)^k + […]
