Mapping the merging zone of late infall in the AB Aur planet-forming system

Kavli Affiliate: Ruobing Dong | First 5 Authors: Jessica Speedie, Ruobing Dong, Richard Teague, Dominique Segura-Cox, Jaime E. Pineda | Summary: Late infall events challenge the traditional view that planet formation occurs without external influence. Here we present deep ALMA $^{12}$CO $J=2-1$ and SO $J_{N}=5_6-4_5$ observations toward AB Aurigae, a Class II disk system with […]

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

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) […]

Disturbed cold gas in galaxy and structure formation

Siwei Zou, Robert A. Simcoe, Patrick Petitjean, Celine Peroux, Jaclyn B. Champagne | Summary: [[{“value”:”Cold and cool gas (T $leq 10^4$ K) in the circumgalactic medium (CGM) and its interaction with galaxies remain poorly understood. Simulations predict that cold gas flows into galaxies through cosmic filaments, determining the disk formation and galaxy evolution. The cold […]
