Discovery of 30 Repeating Fast Radio Burst Sources and Uniform Population Statistics of 80 Repeating Sources from CHIME/FRB

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi Masui | Summary:We present 30 newly discovered repeating fast radio burst (FRB) sources from the second catalog of bursts detected by the FRB backend on the Canadian Hydrogen Intensity Mapping Experiment (CHIME/FRB). These repeaters have extragalactic dispersion measures (DMs) spanning $99.4-1446.0 textpc cm^-3$ and burst rates between $10^-5.7$ and $10^-0.5$ hr$^-1$ scaled […]

Detection of persistent helium absorption in the 91bg-like type Ia Supernova 2022an

Posted by klaurent Peking

Kavli Affiliate: Subo Dong | Summary:We present optical and near-infrared observations of the fast-declining Type Ia supernova (SN Ia) 2022an. The photometric and spectroscopic properties identify it as a standard 91bg-like event; however, our data reveal a relatively narrow absorption feature with a full width at half maximum (FWHM) of 75 angstroms near $1.037,μ$m in […]

Uncovering and Shaping the Latent Representation of 3D Scene Topology in Vision-Language Models

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:Decades of cognitive science establish that humans navigate environments by forming cognitive maps, defined as allocentric and topology-preserving representations of 3D space. While modern Vision-Language Models (VLMs) demonstrate emergent spatial reasoning from 2D egocentric inputs, it remains unclear whether they construct an analogous 3D internal representation. In this paper, we demonstrate […]
