Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Dominika Ďurovčíková, Dominika Ďurovčíková, , , | Summary: Measurements of quasar lifetimes at high redshift indicate that the earliest billion-solar-mass supermassive black holes (SMBHs) have only been active as luminous quasars for less than a million years. Recently, extended Ly$alpha$ nebulae around $zsim6$ quasars have revealed […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Chenghao Wang, Chenghao Wang, , , | Summary: Multi-modal ground-aerial robots have been extensively studied, with a significant challenge lying in the integration of conflicting requirements across different modes of operation. The Husky robot family, developed at Northeastern University, and specifically the Husky v.2 discussed in this […]
Kavli Affiliate: John Silverman | First 5 Authors: Qian Wang, Qian Wang, , , | Summary: During cosmic noon ($zsim1-3$), when both star formation and black hole growth peaked, galaxy mergers are predicted to trigger dual active galactic nuclei (AGN) that eventually coalesce as supermassive black hole (SMBH) binaries. However, observations of dual quasars with […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Xunda Sun, Xunda Sun, , , | Summary: We employ the high-redshift suite of FIRE-2 cosmological hydrodynamic zoom-in simulations to investigate the evolution of gas-phase metallicity radial gradients in galaxies in the epoch of reionization (EoR). Our sample consists of 22 galaxies spanning the redshift range […]
Kavli Affiliate: Erin Kara | First 5 Authors: Laura W. Brenneman, Laura W. Brenneman, , , | Summary: We present a time-averaged spectral analysis of the 2024 XRISM observation of the narrow-line Seyfert-1 galaxy MCG–6-30-15, taken contemporaneously with XMM-Newton and NuSTAR. Our analysis leverages a unique combination of broadband and high-resolution X-ray spectroscopy to definitively […]
Kavli Affiliate: Adam Mantz | First 5 Authors: Benjamin J. Vaughan, Benjamin J. Vaughan, , , | Summary: The conversion of gravitational potential to kinetic energy results in an intracluster medium (ICM) gas with a characteristic temperature near 10 keV in the most massive galaxy clusters. X-ray observations, primarily from Chandra and XMM-Newton, have revealed […]
Kavli Affiliate: Jeremy Nathans | Authors: Yanshu Wang, Amir Rattner, Zhongming Li, Philip M Smallwood and Jeremy Nathans | Summary: In mice, postnatal endothelial cell (EC)-specific knockout of the genes coding for Transforming Growth Factor-Beta Receptor (TGFBR)1 and/or TGFBR2 eliminates TGF-beta signaling in vascular ECs and leads to distinctive central nervous system (CNS) vascular phenotypes. […]
Kavli Affiliate: Zachary Knight | Authors: Brooke C Jarvie, Anagh Ravi, Rhea Nanavati, Longhui Qui, Truong Ly, Jun Y Oh, Olivia K Barnhill and Zachary A Knight | Summary: Calcitonin Gene-Related Peptide (CGRP) neurons in the parabrachial nucleus are critical for sickness and malaise but have also been proposed to control non-aversive (rewarding) satiation. How […]
Kavli Affiliate: Xin Duan | Authors: Daniela Santamaria-Munoz, Raenier V. Reyes, Miranda R. Krueger, Andrea Garcia-Llorca, Brennan Marsh-Armstrong, Xin Duan, Yang Hu, Derek S. Welsbie, Nicholas Marsh-Armstrong, Elisenda Sanz, Albert Quintana, Sergi Simo and Anna La Torre | Summary: Mitochondrial dysfunction is a central hallmark of many optic neuropathies, yet the mechanisms linking intrinsic metabolic […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Xiuwei Xu, Xiuwei Xu, , , | Summary: Towards the aim of generalized robotic manipulation, spatial generalization is the most fundamental capability that requires the policy to work robustly under different spatial distribution of objects, environment and agent itself. To achieve this, substantial human demonstrations need to […]
