Super-Eddington Accretion through a Multiwavelength Lens: Searching for Counterparts of Ultraluminous X-ray Sources
R. Amato, M. Bachetti, R. Soria +8
Ultraluminous X-ray sources (ULXs) represent the closest and most accessible laboratories to study sustained super-Eddington accretion onto compact objects. Over the past decade, t…
Double-hump spectrum, pulse profile dip, and pulsed fraction spectra from the low-accretion regime in the X-ray pulsar MAXI J0655-013
C. Malacaria, S. N. Pike, A. D'Aì +18
Accreting X-ray pulsars (XRPs) undergo different physical regimes depending on the mass accretion rate. Recent observations have shown a dramatic change in the emission properties…
A magnetar outburst with atypical evolution: the case of Swift J1555.2-5402
A. Borghese, F. Coti Zelati, M. Imbrogno +12
The magnetar Swift J1555.2-5402 was discovered in outburst on 2021 June 3 by the Burst Alert Telescope on board the Swift satellite. Early X-ray follow-up revealed a spin period P~…
Aql X-1 from dawn 'til dusk: the early rise, fast state transition and decay of its 2024 outburst
A. Marino, F. Coti Zelati, K. Alabarta +36
Transient Low-Mass X-ray Binaries (LMXBs) are usually first detected by all-sky X-ray monitors when they enter new outbursts, typically at X-ray luminosities above 10…
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…
A supermassive black hole under the radar: Repeating X-ray variability in a Seyfert galaxy
Matteo Imbrogno, Andrea Sacchi, Giovanni Miniutti +4
In the last few years, a few supermassive black holes (SMBHs) have shown short-term (of the order of hours) X-ray variability. Given the limited size of the sample, every new addit…
An ultraviolet burst oscillation candidate from the low-mass X-ray binary EXO 0748-676
A. Miraval Zanon, F. Ambrosino, G. Illiano +15
X-ray burst oscillations are quasi-coherent periodic signals at frequencies close to the neutron star spin frequency. They are observed during thermonuclear Type I X-ray bursts fro…
The hunt for new pulsating ultraluminous X-ray sources: a clustering approach
Nicolò Oreste Pinciroli Vago, Roberta Amato, Matteo Imbrogno +5
The discovery of fast and variable coherent signals in a handful of ultraluminous X-ray sources (ULXs) testifies to the presence of super-Eddington accreting neutron stars, and dra…
The population of hyperluminous X-ray sources as seen by XMM-Newton
Roberta Amato, Erwan Quintin, Hugo Tranin +7
Ultraluminous and hyperluminous X-ray sources (ULXs and HLXs) are among the brightest astrophysical objects in the X-ray sky. While ULXs most likely host stellar-mass compact objec…
Physics of Strong Magnetism with eXTP
Mingyu Ge, Long Ji, Roberto Taverna +47
In this paper we present the science potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission, in its new configuration, for studies of strongly magnetized compact obj…
A NuSTAR study of quasi-periodic oscillations from the ultraluminous X-ray sources in M82
Hamza El Byad, Matteo Bachetti, Silvia Columbu +13
The study of quasi-periodic oscillations in X-ray binaries provides valuable insights into the physics of accretion around compact objects. The M82 galaxy hosts two ultraluminous X…
Wobbling around the clock: magnetically-driven quasi-periodic oscillations in pulsating ultraluminous X-ray sources
M. Veresvarska, M. Imbrogno, R. Amato +8
Ultraluminous X-ray sources (ULXs) are X-ray binary systems containing an accreting neutron star (NS) or black hole emitting at luminosities above the Eddington limit of a $10M_{\o…
On the Binary Nature of the Progenitor of SN2015ap: Insights from Its Light Curve and Spectral Evolution
Fabio Ragosta, Giulia Illiano, Andrea Simongini +3
Stripped-envelope supernovae (SESNe) display a wide range of photometric and spectroscopic behaviours, often reflecting complex progenitor evolution. SN~2015ap is a type Ib event l…
A new pulsating neutron star in the Ultraluminous X-ray source NGC 4559 X7?
F. Pintore, C. Pinto, G. Rodriguez-Castillo +17
Ultraluminous X-ray sources (ULX) are extragalactic objects with X-ray luminosities above the Eddington limit for a 10 Msun black hole (BH). ULXs may host super-Eddington accreting…
