Development and characterization of a fast and low noise readout for the next generation X-ray CCDs

Kavli Affiliate: Sven Herrmann | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Peter Orel, R. Glenn Morris, Gregory Prigozhin | Summary: The broad energy response, low electronic read noise, and good energy resolution have made X-ray Charge-Coupled Devices (CCDs) an obvious choice for developing soft X-ray astronomical instruments over the last half century. They also […]

The Origin of the Relation Between Stellar Angular Momentum and Stellar Mass in Nearby Disk-dominated galaxies

Kavli Affiliate: Luis C. Ho | First 5 Authors: Min Du, Luis C. Ho, Hao-Ran Yu, Victor P. Debattista, | Summary: The IllustrisTNG simulations reproduce the observed scaling relation between stellar specific angular momentum (sAM) $j_{rm s}$ and mass $M_{rm s}$ of central galaxies. We show that the local $j_{rm s}$-$M_{rm s}$ relation ${rm log} […]

The Origin of the Stellar Angular Momentum-Mass Relation: Connecting Galaxies and Halos in IllustrisTNG

Kavli Affiliate: Luis C. Ho | First 5 Authors: Min Du, Luis C. Ho, Hao-Ran Yu, Victor P. Debattista, | Summary: The IllustrisTNG simulations reproduce well the observed scaling relation between specific angular momentum (sAM) $j_{rm s}$ and mass $M_{rm s}$ of galaxies, i.e., the $j_{rm s}$-$M_{rm s}$ relation. This relation develops in disk galaxies […]

Accretion Disk Size Measurements of Active Galactic Nuclei Monitored by the Zwicky Transient Facility

Kavli Affiliate: Luis C. Ho | First 5 Authors: Wei-Jian Guo, Yan-Rong Li, Zhi-Xiang Zhang, Luis C. Ho, Jian-Min Wan | Summary: We compile a sample of 92 active galactic nuclei (AGNs) at z<0.75 with $gri$ photometric light curves from the archival data of the Zwicky Transient Facility and measure the accretion disk sizes via […]
