Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry

Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97

RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…

A binary system in the S cluster close to the supermassive black hole Sagittarius A*

Florian Peißker, Michal Zajacek, Lucas Labadie +4

High-velocity stars and peculiar G objects orbit the central supermassive black hole (SMBH) Sagittarius A* (Sgr A*). Together, the G objects and high-velocity stars constitute the…

Discovery of a Dense Association of Stars in the Vicinity of the Supermassive Black Hole Sgr A*

S. Elaheh Hosseini, Andreas Eckart, Michal Zajaček +3

We focus on a sample of 42 sources in the vicinity of the bow-shock source IRS 1W (N-sources), located at the distance of north-east of the supermassive black hole (SMBH)…

Repeated Partial Tidal Disruptions and Quasi-Periodic Eruptions in SwJ023017.0+283603

Dheeraj Pasham, Eric Coughlin, Chris Nixon +5

SwJ023017.0+283603 (SwJ0230) exhibited soft X-ray (0.3-1.0 keV) eruptions recurring roughly every 22 days. We present results from an extended monitoring campaign of SwJ0230 using…

Revealing EMRI/IMRI candidates with quasiperiodic ultrafast outflows

Michal Zajaček, Petra Suková, Vladimír Karas +7

The first detection of the quasiperiodic ultrafast outflow in the ASASSN-20qc system was reported by Pasham et al. (2024). The outflow is revealed in the soft X-ray spectra as an a…

A combined timing/spectral study of IRAS 13224-3809 using XMM-Newton data

M. D. Caballero-Garcia, I. E. Papadakis, M. Dovciak +3

We present the results from an X-ray variability study of IRAS 13224-3809. This is probably the best source for X-ray reverberation studies since it is X-ray bright, extremely vari…

Monitoring dusty sources in the vicinity of Sgr A*

F. Peißker, S. E. Hosseini, M. Zajacek +5

We trace several dusty infrared sources on their orbit around the supermassive black hole (SMBH) SgrA* in the center of our galaxy. We give an overview of known and unknown sources…
