VLBiMan++: Expanding the Generalization Boundary of Vision-Language Anchored One-Shot Bimanual Manipulation

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:Generalizable bimanual robotic manipulation requires a reusable task prior that can persist across increasingly diverse tasks, objects, scenes, embodiments, and execution conditions, thus avoiding the prohibitive cost of large-scale teleoperated demonstrations and policy retraining. In this work, we present VLBiMan++, an extended framework that expands the generalization boundary of vision-language anchored […]

Chemo-dynamical Analysis of a CNO-Enhanced Ultra Metal-poor Star ($rm[Fe/H] < -4$): Insights into Early Enrichment by Faint Population III Supernova

Posted by klaurent MIT

Kavli Affiliate: Anna Frebel | Summary:We report an independent identification of the ultra metal-poor (UMP) star ($rm[Fe/H] =-4.06$) $Gaia$ DR3 $textttsource_id$ 4795913112968206720 (GDR3_479591) in the $Gaia$ mission’s Blue and Red Photometer ‘XP’ spectro-photometric catalog. We combine multi-band photometry, astrometry, and high-resolution spectroscopy to confirm GDR3_479591 as a red giant-branch (RGB) star located at $sim 6,rm […]

Reigniting the FUSE II: O VI Emission in Massive Elliptical Galaxies

Posted by klaurent MIT

Kavli Affiliate: Michael McDonald | Summary:This is the second paper in a series where we examine archival far-ultraviolet spectroscopy of 29 massive elliptical galaxies from the Far Ultraviolet Spectroscopic Explorer (FUSE) with modern methods. In the first paper, we performed SED modeling with aperture-matched photometry and analyzed the young and old stellar populations in these […]

Spinning Between Models: Continuum and Reflection Constraints in the Intermediate States of GRS 1716-249 and GRS 1739-278

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | Summary:Measurements of stellar-mass black hole spin probe accretion under strong gravity and constrain black hole formation and evolution. Intermediate states, in which thermal disk, coronal, and reflection emission all contribute significantly, are particularly complex environments for spin measurements and useful for probing spectral-modeling systematics. We investigate these effects using paired, […]

Mesoscale Crystallographic Helicity in Confined Tellurium Quantum Wires

Posted by klaurent Berkeley

Kavli Affiliate: Ali Javey | Summary:Helical order can facilitate symmetry breaking and emergent physical responses in crystalline materials, yet how intrinsic chirality manifests beyond atomic length scales remains poorly understood. Here, the direct observation and quantitative characterization of long-range crystallographic helicity in template-grown tellurium (Te) quantum wires on amorphous substrates are reported. Four-dimensional scanning transmission […]

Limits on a Host Star around a Saturn-mass Free-floating Planet Candidate KMT-2024-BLG-0792/OGLE-2024-BLG-0516

Posted by klaurent Peking

Kavli Affiliate: Subo Dong | Summary:Recent studies found a number of short-timescale microlensing events that are thought to be produced by free-floating or wide-orbit planets. The microlensing event KMT-2024-BLG-0792/OGLE-2024-BLG-0516 is currently the only free-floating planet candidate with a directly measured mass ($0.73^+0.25_-0.15$ Saturn masses), derived from joint ground-based and Gaia satellite observations. However, it remains […]

A systematic study of the long-term mid-infrared color variations of Seyfert 1 galaxies

Posted by klaurent Peking

Kavli Affiliate: Luis Ho | Summary:We present a comparative analysis of long-term mid-infrared (MIR) color variations (MCVs) for 1,977 narrow-line Seyfert 1 (NLSy1) and 4,113 broad-line Seyfert 1 (BLSy1) galaxies at $z < 0.3$. Using 14 years of WISE and NEOWISE data, we quantify the correlation between $W1-W2$ color and $W1$ magnitude. We categorize sources […]

Deterministic patterning and alignment of tellurium quantum wires using nanoscale templates

Posted by klaurent Berkeley

Kavli Affiliate: Ali Javey | Summary:Tellurium (Te) is an intriguing one-dimensional (1D) semiconductor that has recently attracted considerable interest as a p-type channel material. However, scalable synthesis methods have lacked control over the orientation and patterning of the Te atomic chains, thus limiting its practical use. Guided by theory, we overcome this challenge using nanowire-shaped […]
