Resolving structure within the iron line profile of Serpens X-1 with XRISM and NuSTAR

Hayden Hall, Renee M. Ludlam, Edward Cackett +2

We present the first simultaneous XRISM and NuSTAR observations of the neutron star low mass X-ray binary Serpens X-1. We perform spectral modeling on the joint observations of XRI…

The emergence of X-ray emission lines during relativistic radio-jet formation in the changing-look active galactic nucleus 1ES 1927+654

Dev R. Sadaula, Sibasish Laha, Eileen T. Meyer +27

We present results from a comprehensive multi-wavelength monitoring campaign of the changing-look active galactic nucleus 1ES 1927+654 during the onset and evolution of a relativis…

Evidence for a shock-compressed magnetic field in the northwestern rim of Vela Jr. from X-ray polarimetry

Dmitry A. Prokhorov, Yi-Jung Yang, Riccardo Ferrazzoli +97

Synchrotron X-ray emission has been detected from nearly a dozen young supernova remnants (SNRs). X-rays of synchrotron origin exhibit linear polarization in a regular, non-randoml…

A View of the Long-Term Spectral Behavior of Ultra Compact X-Ray Binary 4U 0614+091

David L. Moutard, Renee M. Ludlam, Edward M. Cackett +3

In this study, we examine 51 archival NICER observations and 6 archival NuSTAR observations of the neutron star (NS) ultra-compact X-ray binary (UCXB) 4U 0614+091, which span over…

Exploring the high-density reflection model for the soft excess in RBS 1124

A. Madathil-Pottayil, D. J. Walton, Javier García +13

'Bare' active galactic nuclei (AGN) are a subclass of Type 1 AGN that show little or no intrinsic absorption. They offer an unobscured view of the central regions of the AGN and th…

Next Generation Accretion Disk Reflection Model: High-Density Plasma Effects

Yuanze Ding, Javier A. García, Timothy R. Kallman +5

Luminous accretion disks around black holes are expected to have densities of cm, which are high enough such that plasma physics effects become important.…

Modeling Multiple X-Ray Reflection in Super-Eddington Winds

Zijian Zhang, Lars Lund Thomsen, Lixin Dai +7

It has been recently discovered that a few super-Eddington sources undergoing black hole super-Eddington accretion exhibit X-ray reflection signatures. In such new systems, one exp…

Sub-relativistic Outflow and Hours-Timescale Large-amplitude X-ray Dips during Super-Eddington Accretion onto a Low-mass Massive Black Hole in the Tidal Disruption Event AT2022lri

Yuhan Yao, Muryel Guolo, Francesco Tombesi +32

We present the tidal disruption event (TDE) AT2022lri, hosted in a nearby ( Mpc) quiescent galaxy with a low-mass massive black hole ($10^4\,M_\odot < M_{\rm BH} < 10…

Long term variability of Cygnus X-1. VIII. A spectral-timing look at low energies with NICER

Ole König, Guglielmo Mastroserio, Thomas Dauser +19

The Neutron Star Interior Composition Explorer (NICER) monitoring campaign of Cyg X-1 allows us to study its spectral-timing behavior at energies keV across all states. The…
