In March 2024 Cygnus X-3 (Cyg X-3) was in a quenched/hypersoft state (soft/high). During this state a 67 ksec XRISM observations was triggered along with ToO observations with the SMA. During this period there were also supporting observations being made with AMI (radio), NuSTAR (hard X-ray), and Fermi (gamma-ray). The SMA submillimeter observation taken during the XRISM observation revealed...

7. Probing accretion disk plasmas in LMXBs with XRISM

Low mass X-ray binaries (LMXBs) are systems composed of a compact object (black hole or neutron star) and a low mass (< mSun) companion star. The compact object accretes matter from the companion, forming an accretion disk. The gas in the disk is ionized by the strong X-ray emission from the inner disk region, leading to the appearance of photoionized plasmas. Characterizing their properties...

26. The XRISM view of outflows in Black Hole Low-Mass X-ray Binaries

The first year and a half of XRISM science has led to a select number of observations of Black Hole Low Mass X-ray Binaries (BHLMXB), most of which in very unusual states. We will briefly present the context of all these observations, and notably results for :
-A faint soft state exposure of the Black Hole candidate 4U 1630-47 taken at the end of its 2022-2024 outburst. Despite the closest to...
