An Ultra-Short Period Super-Earth and Sub-Neptune Spanning the Radius Valley Orbiting the Kinematic Thick Disk Star TOI-2345

Posted by klaurent MIT

Kavli Affiliate: Robert Goeke | Summary:A crucial chemical link between stars and their orbiting exoplanets is thought to exist. If universal, this connection could affect the formation and evolution of all planets. Therefore, this potential vital link needs testing by characterising exoplanets around chemically-diverse stars. We present the discovery of two planets orbiting the metal-poor, […]

E-MoFlow: Learning Egomotion and Optical Flow from Event Data via Implicit Regularization

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Wenpu Li, Wenpu Li, , , | Summary: The estimation of optical flow and 6-DoF ego-motion, two fundamental tasks in 3D vision, has typically been addressed independently. For neuromorphic vision (e.g., event cameras), however, the lack of robust data association makes solving the two problems separately an […]

Conductance Plateaus at Quantum Hall Integer Filling Factors in Germanium Quantum Point Contacts

Posted by klaurent Delft

Kavli Affiliate: Giordano Scappucci| First 5 Authors: Karina Hudson, Karina Hudson, , , | Summary:Constricting transport through a one-dimensional quantum point contact in the quantum Hall regime enables gate-tunable selection of the edge modes propagating between voltage probe electrodes. Here we investigate the quantum Hall effect in a quantum point contact fabricated on low disorder […]

Enhanced Localization of Dark Lensed Gravitational Wave Events Enables Host Galaxy Identification and Precise Cosmological Inference

Posted by klaurent Peking

Kavli Affiliate: Qingjuan Yu | Summary:Lensed gravitational wave (GW) events are expected to be powerful new probes of cosmology, contingent on redshift measurement by electromagnetic observations. Host galaxy identification is thus crucial but challenging due to poor localization by GW signal alone. In this paper, we show that the third-generation ground-based GW detectors will detect […]

Association of cold gas, massive galaxies, and AGNs in a filamentary protocluster traced by triple narrow-band imaging

Posted by klaurent Tokyo

Kavli Affiliate: Tadayuki Takahashi| First 5 Authors: Kazuki Daikuhara, Kazuki Daikuhara, , , | Summary:We investigate galaxy populations in the HS1700+64 protocluster at $z=2.30$, characterized by two prominent linear filaments traced by spatially extended Ly$α$ blobs. We conducted a wide area mapping of emission line galaxies across the protocluster using the unique combination of three […]

YSO Variability in the W51 Star-Forming Region

Posted by klaurent Peking

Kavli Affiliate: Gregory Herczeg | Summary:Time-domain studies of mid-infrared and submillimeter variability have shown that at least half of protostars are variable. We present a statistical analysis of mid-infrared variability among young stellar objects (YSOs) in the distant, massive star-forming region W51 using NEOWISE data. From a catalog of 81 protostars, 527 disk objects, and […]
