Radio properties of the quasi-periodic eruption source RXJ1301.9+2747 at parsec scales
S. D. von Fellenberg, R. Arcodia, P. Benke +6
Quasi-periodic eruptions (QPEs) are repeating soft X-ray flares associated with galactic nuclei. Several recent works have found evidence that the accretion flow in the galactic nu…

Rapid onset of a Comptonisation zone in the repeating tidal disruption event XMMSL2 J140446.9-251135
R. D. Saxton, T. Wevers, S. van Velzen +11
We report here on observations of a tidal disruption event, XMMSL2 J1404-2511, discovered in an XMM-Newton slew, in a quiescent galaxy at z=0.043. X-ray monitoring covered the epoc…

NICER observations reveal doubled timescales in Ansky's quasi-periodic eruptions (QPEs)
L. Hernández-García, P. Sánchez-Sáez, J. Chakraborty +11
Quasi-periodic eruptions (QPEs) are recurring X-ray bursts originating from the vicinity of supermassive black holes, but their driving mechanisms remain under debate. This study a…
