The missing FeII bump in faint JWST AGN: possible evidence for metal-poor broad-line regions at early cosmic times

Posted by dbos October 29, 2024November 11, 2024Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Bartolomeo Trefoloni, Xihan Ji, Roberto Maiolino, Francesco D’Eugenio, Hannah Übler | Summary: Recent JWST observations have revealed a large population of intermediate/low-luminosity AGN at early times with peculiar properties, different from local AGN or luminous quasars. To better understand the physical conditions in the BLRs of these […]

Separating the control of moving and holding still in post-stroke arm paresis

Posted by klaurent October 29, 2024November 11, 2024Hopkins

Kavli Affiliate: Reza Shadmehr | Authors: Alkis M. Hadjiosif, Kahori Kita, Scott T. Albert, Robert A. Scheidt, Reza Shadmehr and John W. Krakauer | Summary: Moving and holding still have been posited to be under separate control regimes for both eye and arm movements. The paretic arm after stroke is notable for abnormalities both at […]

Sex chromosome gene expression associated with vocal learning following hormonal manipulation in female zebra finches

Posted by klaurent October 28, 2024November 11, 2024Rockefeller

Kavli Affiliate: Erich Jarvis | Authors: Matthew Davenport, Ha Na Choe, Hiroaki Matsunami and Erich D Jarvis | Summary: Zebra finches are sexually dimorphic vocal learners. Males learn to sing by imitating mature conspecifics, but females do not. Absence of song in females is associated with atrophy and apparent repression of several vocal learning brain […]

A circuit model for transsaccadic space updating and mislocalization

Posted by dbos October 28, 2024November 11, 2024Columbia

Kavli Affiliate: Michael Goldberg | Authors: Xiao Wang, Sophia Tsien, Michael E. Goldberg, Mingsha Zhang and Ning Qian | Summary: We perceive a stable, continuous world despite drastic changes of retinal images across saccades. However, while persistent objects in daily life appear stable across saccades, stimuli flashed around saccades can be grossly mislocalized. We address […]

Unfolding X-ray Spectral Data: Conditions and Applications

Posted by dbos October 28, 2024November 11, 2024MIT

Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, David P. Huenemoerder, , , | Summary: We present conditions for which X-ray spectra can be “unfolded” to present accurate representation of the true source spectra. The method we use to unfold the data is implemented in the textit{Interactive Spectral Interpretation Software} citep{Houck2000} […]

Connecting the X-ray/UV variability of Fairall 9 with NICER: A Possible Warm Corona

Posted by dbos October 28, 2024November 11, 2024MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Ethan R. Partington, Edward M. Cackett, Rick Edelson, Keith Horne, Jonathan Gelbord | Summary: The Seyfert 1 AGN Fairall 9 was targeted by NICER, Swift, and ground-based observatories for a $sim$1000-day long reverberation mapping campaign. The following analysis of NICER spectra taken at a two-day cadence provides […]

Blind source separation of the stellar halo

Posted by dbos October 28, 2024November 11, 2024Chicago

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Elliot Y. Davies, Vasily Belokurov, Andrey Kravtsov, Stephanie Monty, GyuChul Myeong | Summary: The stellar halo of the Milky Way comprises an abundance of chemical signatures from accretion events and textit{in-situ} evolution, that form an interweaving tapestry in kinematic space. To untangle this, we consider the mixtures […]

$texttt{StreamSculptor}$: Hamiltonian Perturbation Theory for Stellar Streams in Flexible Potentials with Differentiable Simulations

Posted by dbos October 28, 2024November 11, 2024Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Jacob Nibauer, Ana Bonaca, David N. Spergel, Adrian M. Price-Whelan, Jenny E. Greene | Summary: Stellar streams retain a memory of their gravitational interactions with small-scale perturbations. While perturbative models for streams have been formulated in action-angle coordinates, a direct transformation to these coordinates is only […]
