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

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 […]

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

Kavli Affiliate: Daniel R. Wilkins | 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 work in accreting BH systems spanning a broad range of mass. However, the low-mass end of AGNs has […]

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

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 […]

Enhancing the sensitivity of the LUX-ZEPLIN (LZ) dark matter experiment to low energy signals

Kavli Affiliate: T. A. Shutt | Summary:Two-phase xenon detectors, such as that at the core of the forthcoming LZ dark matter experiment, use photomultiplier tubes to sense the primary (S1) and secondary (S2) scintillation signals resulting from particle interactions in their liquid xenon target. This paper describes a simulation study exploring two techniques to lower […]

Dark Matter Constraints from a Unified Analysis of Strong Gravitational Lenses and Milky Way Satellite Galaxies

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Simon Birrer, Daniel Gilman, Risa H. Wechsler, Xiaolong Du | Summary: Joint analyses of small-scale cosmological structure probes are relatively unexplored and promise to advance measurements of microphysical dark matter properties using heterogeneous data. Here, we present a multidimensional analysis of dark matter […]
