Full-sky Models of Galactic Microwave Emission and Polarization at Sub-arcminute Scales for the Python Sky Model

Posted by dbos Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: The Pan-Experiment Galactic Science Group, :, Julian Borrill, Susan E. Clark, Jacques Delabrouille | Summary: Polarized foreground emission from the Galaxy is one of the biggest challenges facing current and upcoming cosmic microwave background (CMB) polarization experiments. We develop new models of polarized Galactic dust and […]

Aeos: The Impact of Pop III Initial Mass Function and Star-by-Star Models in Galaxy Simulations

Posted by dbos MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Kaley Brauer, Jennifer Mead, John H. Wise, Greg L. Bryan, Mordecai-Mark Mac Low | Summary: We explore the effect of variations in the Population III (Pop III) initial mass function (IMF) and star-by-star feedback on early galaxy formation and evolution using the Aeos simulations. We compare simulations […]

Spectroastrometry and Reverberation Mapping of Active Galactic Nuclei. II. Measuring Geometric Distances and Black Hole Masses of Four Nearby Quasars

Posted by dbos Peking

Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Yan-Rong Li, Jinyi Shangguan, Jian-Min Wang, Ric Davies, Daryl J. Santos | Summary: The geometric distances of active galactic nuclei (AGNs) are challenging to measure because of their exceptionally compact structure yet vast cosmic distances. A combination of spectroastrometry and reverberation mapping (SARM) of broad-line regions (BLRs) […]

Asteroseismic Study of Subgiants and Giants of the Open Cluster M67 using Kepler/K2: Expanded Sample and Precise Masses

Posted by dbos MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Claudia Reyes, Dennis Stello, Marc Hon, Yaguang Li, Timothy R. Bedding | Summary: Sparked by the asteroseismic space revolution, ensemble studies have been used to produce empirical relations linking observed seismic properties and fundamental stellar properties. Cluster stars are particularly valuable because they have the same metallicity, […]
