Accurate Determination of Chemical Abundances near a Supermassive Black Hole

The XRISM collaboration

The metal abundances in galactic nuclei carry key information on the history of star formation and mass transfer in central regions of galaxies. X-ray fluorescence analysis is a un…

Evidence of mutually exclusive outflow forms from a black hole X-ray binary

Zuobin Zhang, Jiachen Jiang, Francesco Carotenuto +13

Accretion onto black holes often leads to the launch of outflows that significantly influence their surrounding environments. The two primary forms of these outflows are X-ray disk…

Stratified wind from a super-Eddington X-ray binary is slower than expected

XRISM collaboration, Marc Audard, Hisamitsu Awaki +132

Accretion discs in strong gravity ubiquitously produce winds, seen as blueshifted absorption lines in the X-ray band of both stellar mass X-ray binaries (black holes and neutron st…

Low-frequency spectra of neutron star + OB supergiant binaries: Does wind density drive persistent and flaring modes of accretion?

J. van den Eijnden, L. Sidoli, M. Díaz Trigo +10

Neutron star high-mass X-ray binaries are well-studied in wavebands between the infrared and hard X-rays. Their low-frequency millimeter and radio properties, on the other hand, re…

Chromatic periodic activity down to 120 MHz in a Fast Radio Burst

Inés Pastor-Marazuela, Liam Connor, Joeri van Leeuwen +34

Fast radio bursts (FRBs) are extragalactic astrophysical transients whose brightness requires emitters that are highly energetic, yet compact enough to produce the short, milliseco…

Accretion disks and coronae in the X-ray flashlight

N. Degenaar, D. R. Ballantyne, T. Belloni +10

Plasma accreted onto the surface of a neutron star can ignite due to unstable thermonuclear burning and produce a bright flash of X-ray emission called a Type-I X-ray burst. Such e…

Simultaneous X-ray and radio observations of the radio-mode switching pulsar PSR B1822-09

W. Hermsen, L. Kuiper, J. W. T. Hessels +7

We report on simultaneous X-ray and radio observations of the radio-mode-switching pulsar PSR B1822-09 with ESA's XMM-Newton and the WSRT, GMRT and Lovell radio telescopes. PSR B18…

Searching for small-scale diffuse emission around SGR 1806-20

D. Viganò, N. Rea, P. Esposito +6

Diffuse radio emission was detected around the soft gamma-ray repeater SGR 1806-20, after its 2004 powerful giant flare. We study the possible extended X-ray emission at small scal…
