A systematic study of AGN feedback in a disk galaxy using MACER. III. High Gas Fractions in AGN Hosts

Posted by klaurent Peking

Kavli Affiliate: Jinyi Shangguan | Summary:We use high-resolution hydrodynamic simulations in the MACER framework to explain why low-redshift PG quasar hosts can retain substantial cold-gas reservoirs, with gas fractions and gas-to-stellar mass ratios showing little dependence on instantaneous AGN luminosity. This paper is the third in a series systematically studying AGN feedback in a disk […]

A Beta-Binomial Model for Estimating Zero- or One-inflated Pain Trajectories

Posted by dbos Hopkins, This Week: Neuroscience

Kavli Affiliate: Martin Lindquist | Authors: Yanxi Liu, Richard E. Harris, Daniel Clauw, Emine Bayman, Andrew Leroux and Martin A. Lindquist | Summary: Chronic pain is a widespread public health issue that imposes substantial health, emotional, and economic burdens on individuals and communities. Because pain is subjective and lacks objective biomarkers, it is typically measured […]

Directional alignment of turn-related activity with locomotor dynamics in the superior colliculus

Posted by dbos This Week: Neuroscience, UCSD / Salk

Kavli Affiliate: Massimo Scanziani and Loren Frank | Authors: Cameron Wilhite, Loren M. Frank and Massimo Scanziani | Summary: Fluid behavior requires temporal coordination across brain systems that orchestrate movement. A clear example is locomotion, in which left and right turns are not only precisely coordinated with the ongoing stepping rhythm but occur at opposite […]

AlV$_2$O$_4$ thin films via in-situ interfacial topotaxy

Posted by klaurent Caltech

Kavli Affiliate: Joseph Falson | Summary:Conventional oxide epitaxy approaches face challenges when the oxidation conditions of constituent elements differ significantly. Here we demonstrate that V–O thin films can serve as solid-phase precursors for epitaxial AlV$_2$O$_4$, comprising a pyrochlore V$^2.5+$ network coexisting with AlO$_4$ tetrahedra within the spinel structure. The epitaxial AlV$_2$O$_4$/Al$_2$O$_3$ (0001) heterostructures are realized […]

NIRC2-Pol: First Light of Near-Infrared Polarimetry on Keck II

Posted by klaurent Caltech

Kavli Affiliate: Dimitri Mawet| Summary:NIRC2, the Near Infrared Camera 2 on the Keck II telescope, was recently upgraded with a new suite of polarimetric observing modes. The new polarimetry modes (referred to as NIRC2-Pol) open up a wide range of new studies, including investigations of exoplanets, the Galactic center, active galactic nuclei, and solar system […]

The Photonic Lantern Nuller: from concept to laboratory and on-sky demonstrations

Posted by klaurent Caltech

Kavli Affiliate: Dimitri Mawet| Summary:This thesis work presents the conceptual design and experimental characterization of the Photonic Lantern Nuller instrument, which uses a multimode-to-single-mode demultiplexing waveguide to cancel out starlight while maintaining planet light, allowing for the direct characterization of planets at a telescope’s diffraction limit. The PLN was experimentally characterized in the lab, where […]

Active gaze behavior organizes V1 activity in freely-moving marmosets

Posted by dbos This Week: Neuroscience, UCSD / Salk

Kavli Affiliate: Cory Miller | Authors: Jingwen Li, Vikram Pal Singh, Jude F. Mitchell, Alexander C. Huk and Cory T. Miller | Summary: Human and nonhuman primates rely heavily on vision to actively explore and navigate their environment. Although primate visual cortex has been studied extensively in head-fixed animals, little is known about how the […]

Working memory retention by medial entorhinal cortex low-dimensional neural dynamics

Posted by dbos Hopkins, This Week: Neuroscience, UCSD / Salk

Kavli Affiliate: Jill Leutgeb | Authors: Li Yuan, Jiarui Wang, Xiaohe Li, Wenxi Li, Johnatan Aljadeff, Jill K Leutgeb and Stefan Leutgeb | Summary: The ability to retain information over tens of seconds is essential for carrying out many routine tasks. Recurrently connected circuits are thought to support memory over these timescales, yet how they […]

Spatiotemporal Dissociation of Human Amygdala Response to Negative Affect

Posted by dbos Hopkins, This Week: Neuroscience

Kavli Affiliate: Martin Lindquist | Authors: Ke Bo, Martin Lindquist, Peter J Gianaros and Tor Wager | Summary: The amygdala is central to negative affect and a primary target of top-down regulation, yet its temporal dynamics remain poorly characterized. Most fMRI studies model stimulus-evoked amygdala activity with a canonical hemodynamic response function and collapse across […]
