Rapid Orbital Decay in the Ultracompact Double-degenerate Binary eRASSU J060839.5704014
Rahul Sharma, Chandreyee Maitra, Frank Haberl +9
We present timing and spectral analysis of the recently identified ultracompact double-degenerate (DD) white dwarf binary eRASSU J060839.5704014 using observations from NICER an…
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…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
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…
Thermonuclear X-ray bursts across the eclipse transitions in the LMXBs EXO 0748-676 and XTE J1710-281
Ketan Rikame, Biswajit Paul, Rahul Sharma +1
The primary radiation from thermonuclear X-ray bursts observed in the neutron star low-mass X-ray binary (LMXB) systems can interact with various parts of the binary system. This i…
Intriguing nature of AM Her type candidate CXOU J204734.8+300105
Rahul Sharma, Chetana Jain, Biswajit Paul +2
The detection and characterization of periodic X-ray signals are crucial for identifying new compact objects and studying the mechanisms powering their emission. We report on the t…
