The discovery of the 528.6 Hz accreting millisecond X-ray pulsar MAXI J1816-195

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Peter Bult, Diego Altamirano, Zaven Arzoumanian, Deepto Chakrabarty, Jérôme Chenevez | Summary: We present the discovery of 528.6 Hz pulsations in the new X-ray transient MAXI J1816-195. Using NICER, we observed the first recorded transient outburst from the neutron star low-mass X-ray binary MAXI J1816-195 over a […]

The Host Galaxy and Rapidly Evolving Broad-line Region in the Changing-look Active Galactic Nucleus 1ES 1927+654

Kavli Affiliate: Erin Kara | First 5 Authors: Ruancun Li, Luis C. Ho, Claudio Ricci, Benny Trakhtenbrot, Iair Arcavi | Summary: Changing-look active galactic nuclei (AGNs) present an important laboratory to understand the origin and physical properties of the broad-line region (BLR). We investigate follow-up optical spectroscopy spanning $sim 500$ days after the outburst of […]

Towards precision particle background estimation for future X-ray missions: correlated variability between Chandra ACIS and AMS

Kavli Affiliate: Richard Foster | First 5 Authors: Catherine E. Grant, Eric D. Miller, Marshall W. Bautz, Richard Foster, Ralph P. Kraft | Summary: A science goal of many future X-ray observatories is mapping the cosmic web through deep exposures of faint diffuse sources. Such observations require low background and the best possible knowledge of […]
