Dimming GRS 1915+105 observed with NICER and Insight--HXMT
M. Zhou, V. Grinberg, A. Santangelo +6
The black hole X-ray binary GRS 1915+105 was bright for 26 years since its discovery and is well-known for its disk instabilities, quasi-periodic oscillations, and disk wind signat…
A NICER View of a Highly-Absorbed Flare in GRS 1915+105
J. Neilsen, J. Homan, J. F. Steiner +4
After 26 years in outburst, the black hole X-ray binary GRS 1915+105 dimmed considerably in early 2018; its flux dropped sharply in mid-2019, and it has remained faint ever since.…
The destruction and recreation of the X-ray corona in a changing-look Active Galactic Nucleus
C. Ricci, E. Kara, M. Loewenstein +16
We present the drastic transformation of the X-ray properties of the active galactic nucleus 1ES 1927+654, following a changing-look event. After the optical/UV outburst the power-…
A Persistent Disk Wind in GRS 1915+105 with NICER
Joey Neilsen, E. Cackett, R. A. Remillard +13
The bright, erratic black hole X-ray binary GRS 1915+105 has long been a target for studies of disk instabilities, radio/infrared jets, and accretion disk winds, with implications…
The Closest Look at 1H0707-495: X-ray Reverberation Lags with 1.3 Ms of Data
E. Kara, A. C. Fabian, E. M. Cackett +4
Reverberation lags in AGN were first discovered in the NLS1 galaxy, 1H0707-495. We present a follow-up analysis using 1.3 Ms of data, which allows for the closest ever look at the…
