Discovery of soft and hard X-ray time lags in low-mass AGNs

Posted by klaurent Stanford

Kavli Affiliate: Daniel R. Wilkins | First 5 Authors: Labani Mallick, Daniel R. Wilkins, William N. Alston, Alex Markowitz, Barbara De Marco | Summary: The scaling relations between the black hole (BH) mass and soft lag properties for both active galactic nuclei (AGNs) and BH X-ray binaries (BHXRBs) suggest the same underlying physical mechanism at […]

Measuring $H_0$ using X-ray and SZ effect observations of dynamically relaxed galaxy clusters

Posted by klaurent Stanford

Kavli Affiliate: Adam B. Mantz | First 5 Authors: Jenny T. Wan, Adam B. Mantz, Jack Sayers, Steven W. Allen, R. Glenn Morris | Summary: We use a sample of 14 massive, dynamically relaxed galaxy clusters to constrain the Hubble Constant, $H_0$, by combining X-ray and Sunyaev-Zel’dovich (SZ) effect signals measured with Chandra, Planck and […]
