Detecting the Black Hole Candidate Population in M51's Young Massive Star Clusters: Constraints on Accreting Intermediate Mass Black Holes
Kristen C. Dage, Evangelia Tremou, Bolivia Cuevas Otahola +24
Intermediate mass black holes (10^2 < M_BH< 10^5 Msun) are an open question in our understanding of black hole evolution and growth. They have long been linked to dense star cluste…
A spectro-temporal view of normal branch oscillations in Cygnus X-2 as seen by NICER and NuSTAR
Malu Sudha, Renee M. Ludlam, Diego Altamirano +2
We report the spectro-temporal study of the neutron star low mass X-ray binary Cygnus X-2 using NICER and NuSTAR data while the source was in the normal branch (NB). We detect a no…
Connecting the X-ray/UV variability of Fairall 9 with NICER: A Possible Warm Corona
Ethan R. Partington, Edward M. Cackett, Rick Edelson +7
The Seyfert 1 AGN Fairall 9 was targeted by NICER, Swift, and ground-based observatories for a 1000-day long reverberation mapping campaign. The following analysis of NICER s…
STROBE-X Mission Overview
Paul S. Ray, Peter W. A. Roming, Andrea Argan +54
We give an overview of the science objectives and mission design of the Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays (STROBE-X) observatory, which has been…
AGN STORM 2: X. The origin of the interband continuum delays in Mrk 817
Hagai Netzer, Michael R. Goad, Aaron J. Barth +26
The local (z=0.0315) AGN Mrk 817, was monitored over more than 500 days with space-borne and ground-based instruments as part of a large international campaign AGN STORM 2. Here, w…
