TOI-4504: Exceptionally large Transit Timing Variations induced by two resonant warm gas giants in a three planet system

Posted by dbos MIT

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Michaela Vítková, Rafael Brahm, Trifon Trifonov, Petr Kabáth, Andrés Jordán | Summary: We present a joint analysis of TTVs and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known transit timing variations (TTVs), with a peak-to-node […]

The First JWST View of a 30-Myr-old Protoplanetary Disk Reveals a Late-stage Carbon-rich Phase

Posted by dbos Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Feng Long, Ilaria Pascucci, Adrien Houge, Andrea Banzatti, Klaus M. Pontoppidan | Summary: We present a JWST MIRI/MRS spectrum of the inner disk of WISE J044634.16$-$262756.1B (hereafter J0446B), an old ($sim$34 Myr) M4.5 star but with hints of ongoing accretion. The spectrum is molecule-rich and dominated […]

SZ-X-ray Surface Brightness Fluctuations in the SPT-XMM clusters

Posted by dbos Chicago

Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Charles Romero, Massimo Gaspari, Gerrit Schellenberger, Bradford A. Benson, Lindsey E. Bleem | Summary: The hot plasma in galaxy clusters, the intracluster medium (ICM), is expected to be shaped by subsonic turbulent motions, which are key for heating, cooling, and transport mechanisms. The turbulent motions contribute […]

A quantized anomalous Hall effect above 4.2 K in stacked topological insulator/magnet bilayers

Posted by dbos Cornell

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Rakshit Jain, Matthew Roddy, Vishakha Gupta, Benjamin Huang, Hasan M. Sayeed | Summary: Quantized anomalous Hall effects (QAHEs) occur in remarkable electronic states which possess not only quantized Hall signals but in some cases regions of dissipationless electron transport. The initial demonstrations of a QAHE in […]

Baseband control of single-electron silicon spin qubits in two dimensions

Posted by dbos Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Florian K. Unseld, Brennan Undseth, Eline Raymenants, Yuta Matsumoto, Saurabh Karwal | Summary: Micromagnet-enabled electric-dipole spin resonance (EDSR) is an established method of high-fidelity single-spin control in silicon. However, the resulting architectural limitations have restrained silicon quantum processors to one-dimensional arrays, and heating effects from the associated […]

Towards Flexible 3D Perception: Object-Centric Occupancy Completion Augments 3D Object Detection

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Chaoda Zheng, Feng Wang, Naiyan Wang, Shuguang Cui, Zhen Li | Summary: While 3D object bounding box (bbox) representation has been widely used in autonomous driving perception, it lacks the ability to capture the precise details of an object’s intrinsic geometry. Recently, occupancy has emerged as a […]

EvTTC: An Event Camera Dataset for Time-to-Collision Estimation

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Kaizhen Sun, Jinghang Li, Kuan Dai, Bangyan Liao, Wei Xiong | Summary: Time-to-Collision (TTC) estimation lies in the core of the forward collision warning (FCW) functionality, which is key to all Automatic Emergency Braking (AEB) systems. Although the success of solutions using frame-based cameras (e.g., Mobileye’s solutions) […]
