Mixed Multi-Level Visual, Reward, and Motor Signals in Dorsomedial Frontal Cortex Area F7 during Active Naturalistic Video Exploration

Posted by klaurent Rockefeller

Kavli Affiliate: Winrich Freiwald | Authors: Farid Aboharb, Stephen Serene, Julia Sliwa and Winrich A Freiwald | Summary: In the primate brain the frontal lobes support complex functions, including social cognition. Understanding the functional organization of these regions requires an approach for rich functional characterization. Here we used a novel paradigm, the visual exploration of […]

Noise Reduction Methods for Large-scale Intensity-mapping Measurements with Infrared Detector Arrays

Posted by klaurent Caltech

Kavli Affiliate: James Bock | First 5 Authors: Grigory Heaton, Walter Cook, James Bock, Jill Burnham, Sam Condon | Summary: Intensity mapping observations measure galaxy clustering fluctuations from spectral-spatial maps, requiring stable noise properties on large angular scales. We have developed specialized readouts and analysis methods for achieving large-scale noise stability with Teledyne 2048$times$2048 H2RG […]

In-situ vs accreted Milky Way globular clusters: a new classification method and implications for cluster formation

Posted by klaurent Chicago

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Vasily Belokurov, Andrey Kravtsov, , , | Summary: We present a new scheme for the classification of the in-situ and accreted globular clusters (GCs). The scheme uses total energy $E$ and $z$-component of the orbital angular momentum and is calibrated using [Al/Fe] abundance ratio. We demonstrate that […]

Simulating ionization feedback from young massive stars: impact of numerical resolution

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Yunwei Deng, Hui Li, Rahul Kannan, Aaron Smith, Mark Vogelsberger | Summary: Modelling galaxy formation in hydrodynamic simulations has increasingly adopted various radiative transfer methods to account for photoionization feedback from young massive stars. However, the evolution of HII regions around stars begins in dense star-forming clouds […]
