X-ray Reverberation Mapping of Ark 564 using Gaussian Process Regression

Posted by klaurent Stanford

Kavli Affiliate: Daniel R. Wilkins | Summary:Ark 564 is an extreme high-Eddington Narrow-line Seyfert 1 galaxy, known for being one of the brightest, most rapidly variable soft X-ray AGN, and for having one of the lowest temperature coronae. Here we present a 410-ks NuSTAR observation and two 115-ks XMM-Newton observations of this unique source, which […]

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Kevin B. Burdge, Kareem El-Badry, Thomas R. Marsh, Saul Rappaport, Warren R. Brown | Summary: In over a thousand known cataclysmic variables (CVs), where a white dwarf is accreting from a hydrogen-rich star, only a dozen have orbital periods below 75 minutes. One way to achieve these […]
