A 2D Gabor-wavelet baseline model out-performs a 3D surface model in scene-responsive cortex

Posted by dbos UCSD / Salk

Kavli Affiliate: John Serences | Authors: Anna Shafer-Skelton, Timothy F Brady and John T Serences | Summary: Understanding 3D representations of spatial information, particularly in naturalistic scenes, remains a significant challenge in vision science. This is largely because of conceptual difficulties in disentangling higher-level 3D information from co-occurring features and cues (e.g., the 3D shape […]

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

Posted by klaurent MIT

Kavli Affiliate: Roland Vanderspek | 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 amplitude of $sim$ 2 days, the largest value ever observed, and a super-period of $sim$ […]

Isochronous and period-doubling diagrams for symplectic maps of the plane

Posted by klaurent Tokyo

Kavli Affiliate: Young-kee Kim | Summary:Symplectic mappings of the plane serve as key models for exploring the fundamental nature of complex behavior in nonlinear systems. Central to this exploration is the effective visualization of stability regimes, which enables the interpretation of how systems evolve under varying conditions. While the area-preserving quadratic Hénon map has received […]

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 […]
