X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Accreting Compact Object Binaries with the SKA
Aru Beri, Francesco Carotenuto, Rob P. Fender +4
Accreting binary systems provide a time-resolved view of the accretion and ejection processes that are seen in all classes of compact objects, from stellar-mass to supermassive. Th…
Accretion geometry and spectral evolution in 1A 1118-61: a comparison of the 2009 and 2026 outbursts
Kinjal Roy, Aru Beri, Rahul Sharma +1
We present a detailed spectro-temporal study of the Be X-ray binary pulsar during its brightest recorded outburst in 2026, using \textit{Swift} and \textit{NuSTAR} o…
Probing accretion dynamics and spin evolution in the X-ray pulsar RX J0520.5-6932 during its 2024 Outburst
Rahul Sharma, Aru Beri, Biswajit Paul +3
After nearly a decade of quiescence, the transient Be/X-ray binary pulsar RX J0520.5-6932 underwent an outburst in 2024. We performed X-ray monitoring of the source with NICER and…
Probing spectral variability in NGC 4490 ULX-8 over 24 years of XMM-Newton, Chandra and Swift-XRT observations
Tarang Vashisht, Aru Beri, Tanuman Ghosh +2
We present a spectral variability study of the ultraluminous X-ray source NGC 4490 ULX-8 based on 14 Chandra, 6 XMM-Newton and 19 Swift-XRT observations obtained between 2000 and 2…
Broadband study of the Be X-ray binary RX J0520.5-6932 during its outburst in 2024
H. N. Yang, C. Maitra, G. Vasilopoulos +18
A new giant outburst of the Be X-ray binary RX J0520.5-6932 was detected and subsequently observed with several space-borne and ground-based instruments. This study presents a comp…
Identification of the optical counterpart of the fast X-ray transient EP240414a
S. Srivastav, T. -W. Chen, J. H. Gillanders +26
Fast X-ray transients (FXTs) are extragalactic bursts of X-rays first identified in archival X-ray data, and now routinely discovered by the Einstein Probe in real time, which is c…
Modelling Neutron-Star Ocean Dynamics
F. Gittins, T. Celora, A. Beri +1
We re-visit the calculation of mode oscillations in the ocean of a rotating neutron star, which may be excited during thermonuclear X-ray bursts. Our present theoretical understand…
