Relativistic outflows power a quasi-periodic eruption: constraints on energetics, mass loss, and emission mechanisms

Joheen Chakraborty, Erin Kara, Wenbin Lu +17

Quasi-periodic eruptions (QPEs) are recurring bursts of X-ray radiation originating from supermassive black holes (SMBHs). They are an unprecedented type of structured, high-amplit…

Kinematically Resolving the Fe K Complex in Her X-1: The Accretion Disk and Ionized Wind Across X-ray Eclipses

Koh Sakamoto, Teruaki Enoto, Peter Kosec +8

We present XRISM/Resolve spectroscopy of Her X-1 across three X-ray eclipses observed in September 2024, resolving its iron K complex through the ingress, mid-eclipse, and egress p…

Dissecting the Nuclear Structure of NGC 5548 with XRISM. I. Physical Properties of the Highly Ionized Outflows

Missagh Mehdipour, Jon M. Miller, Jelle S. Kaastra +21

We present a detailed spectral analysis of an X-Ray Imaging and Spectroscopy Mission (XRISM) observation of the prototypical Seyfert 1 galaxy NGC 5548. XRISM's Resolve microcalorim…

Peering through the dip: IXPE unveils the extended scattering environment of GX 13+1

Alessandro Di Marco, Fabio La Monaca, Luigi Stella +17

Neutron star low-mass X-ray binaries feature complex accretion geometries, often including an accretion disk corona or disk winds. Here, a study of the highly inclined dipping sour…

Investigating the Periodic X-ray Behaviour in the Eclipsing AGN NGC 6814

T. O. Hodd, L. C. Gallo, A. G. Gonzalez +2

A 2016 XMM-Newton X-ray light curve of the Seyfert 1.5 galaxy NGC 6814 exhibited clear eclipsing behaviour, with distinct ingress and egress, during half of the observation. Here,…

Sloshing Motions in Abell 3571 Revealed by XRISM/Resolve Velocity Mapping

Itsuki Aihara, Congyao Zhang, Sora Nakajima +12

Minor mergers can induce sloshing motions in the intracluster medium, leaving characteristic signatures in the thermodynamic structure and gas kinematics of cluster cores. Abell 35…
