The growth of the gargantuan black holes powering high-redshift quasars and their impact on the formation of early galaxies and protoclusters

Posted by klaurent Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Jake S. Bennett, Debora Sijacki, Tiago Costa, Nicolas Laporte, Callum Witten | Summary: High-redshift quasars ($zgtrsim6$), powered by black holes (BHs) with large inferred masses, imply rapid BH growth in the early Universe. The most extreme examples have inferred masses of $sim ! 10^9,$M$_odot$ at $z = […]

Multicore fiber optic imaging reveals that astrocyte calcium activity in the cerebral cortex is modulated by internal motivational state

Posted by klaurent Hopkins

Kavli Affiliate: Jin Kang, Dwight Bergles | Authors: Yung-Tian A. Gau, Eric Hsu, Jaepyeong Cha, Rebecca W. Pak, Loren L. Looger, Jin U. Kang and Dwight E. Bergles | Summary: Astrocytes are a direct target of neuromodulators and can influence neuronal activity on broad spatial and temporal scales through their close proximity to synapses. However, […]

Inverse problems for Dirac operators with a constant delay less than half of the interval

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: In this work, we consider Dirac-type operators with a constant delay less than half of the interval and not less than two fifths of the interval. For our considered Dirac-type operators, an inverse spectral problem is studied. Specifically, reconstruction of two […]
