Three-Dimensional Expansion of Iron Ejecta in Cassiopeia A with Chandra and XRISM
Aya Bamba, Tomoki Kadoya, Kouichi Hagino +4
Measurement of the expansion structure of ejecta in supernova remnants (SNRs) provides important information about their explosion mechanism. We combine Chandra proper-motion measu…
The 2021 outburst of the recurrent nova RS Ophiuchi observed in X-rays by the Neil Gehrels Swift Observatory: a comparative study
K. L. Page, A. P. Beardmore, J. P. Osborne +12
On 2021 August 8, the recurrent nova RS Ophiuchi erupted again, after an interval of 15.5 yr. Regular monitoring by the Neil Gehrels Swift Observatory began promptly, on August 9.9…
A Swift study of long-term changes in the X-ray flaring properties of Sagittarius A*
A. Andrés, J. van den Eijnden, N. Degenaar +12
The radiative counterpart of the supermassive black hole at the Galactic Centre, Sagittarius A*, displays flaring emission in the X-ray band atop a steady, quiescent level. Flares…
Long-term X-ray Variability of the Symbiotic System RT Cru based on Chandra Spectroscopy
A. Danehkar, M. Karovska, J. J. Drake +1
RT Cru belongs to the rare class of hard X-ray emitting symbiotics, whose origin is not yet fully understood. In this work, we have conducted a detailed spectroscopic analysis of X…
The X-ray Emissivity of Low-Density Stellar Populations
C. O. Heinke, M. G. Ivanov, E. W. Koch +17
The dynamical production of low-mass X-ray binaries and brighter cataclysmic variables (CVs) in dense globular clusters is well-established. We investigate how the X-ray emissivity…
XMMSL2 J144605.0+685735 : a slow tidal disruption event
R. D. Saxton, A. M. Read, S. Komossa +6
Aims. We investigate the evolution of X-ray selected tidal disruption events. Methods. New events are found in near-real time data from XMM-Newton slews and are monitored by multi-…
