Supercritical accretion onto compact objects powers a massive wind that is optically thick and Eddington-limited. If most of the hard X-rays from the central disk are obscured by the wind, the source will display a blackbody-like spectrum with a luminosity scaled with the mass of the compact object. From the Chandra archive of nearby galaxies, we selected a sample of luminous and very soft sources and excluded contaminations from foreground objects and supernova remnants. They are found to be… Expand

A Wind-disk Self-irradiation Model for Supercritical Accretion
Optical emission from actively accreting X-ray binaries is dominated by X-ray reprocessing on the outer disk. In the regime of supercritical accretion, strong radiation will power a massive wind thatExpand
Super-Eddington accretion onto the Galactic ultraluminous X-ray pulsar Swift J0243.6+6124
We report on the spectral behavior of the first Galactic ultraluminous X-ray pulsar Swift J0243.6+6124 with NuSTAR observations during its 2017-2018 outburst. At sub-Eddington levels, the sourceExpand
A model for microquasars of Population III
Current simulations indicate that the first stars were formed predominantly in binary systems. The study of the contribution of the first accreting binary systems to the reionization and heating ofExpand
The unusual broad-band X-ray spectral variability of NGC 1313 X-1 seen with XMM–Newton, Chandra, and NuSTAR
We present results from the major coordinated X-ray observing program on the ULX NGC 1313 X-1 performed in 2017, combining $XMM$-$Newton$, $Chandra$ and $NuSTAR$, focusing on the evolution of theExpand
M51 ULX-7: superorbital periodicity and constraints on the neutron star magnetic field
In the current work we explore the applicability of standard theoretical models of accretion to the observed properties of M51 ULX-7. The spin-up rate and observed X-ray luminosity are evidence of aExpand
Possible Periodic Dips in the Pulsating Ultraluminous X-Ray Source M51 ULX-7
We report the discovery of possible periodic X-ray dips in a pulsating ultraluminous X-ray source, M51 ULX-7, with archival Chandra observations. With ∼20 days of monitoring in the superorbitalExpand
A Sparkler in the Fireworks Galaxy: Discovery of an Ultraluminous X-ray Transient with a Strong Oxygen Line in NGC 6946
We discovered and studied an ultraluminous X-ray source (CXOU J203451.1+601043) that appeared in the spiral galaxy NGC 6946 at some point between 2008 February and 2012 May, and has remained atExpand
Linking Soft Excess in Ultraluminous X-Ray Sources with Optically Thick Wind Driven by Supercritical Accretion
Supercritical accretion onto compact objects may drive massive winds that are nearly spherical, optically thick, and Eddington limited. Blackbody emission from the photosphere is the directExpand


Soft, potentially thermal spectral components observed in some ultra-luminous X-ray sources (ULXs) can be fit with models for emission from cool, optically thick accretion disks. If that descriptionExpand
An ultraluminous X-ray source powered by an accreting neutron star
The majority of ultraluminous X-ray sources are point sources that are spatially offset from the nuclei of nearby galaxies and whose X-ray luminosities exceed the theoretical maximum for sphericalExpand
Supercritically accreting stellar mass black holes as ultraluminous X-ray sources
We derive the luminosity‐temperature relation for the supercritically accreting black holes (BHs) and compare it to the data on ultraluminous X-ray sources (ULXs). At super-Eddington accretion rates,Expand
Evidence for Precession due to Supercritical Accretion in Ultraluminous X-Ray Sources
Most ultraluminous X-ray sources (ULXs) are thought to be supercritical accreting compact objects, where massive outflows are inevitable. Using the long-term monitoring data with the Swift X-rayExpand
Optically thick outflows in ultraluminous supersoft sources
Ultraluminous supersoft sources (ULSs) are defined by a thermal spectrum with colour temperatures ~0.1 keV, bolometric luminosities ~ a few 10^39 erg/s, and almost no emission above 1 keV. It hasExpand
A spectral-timing model for ULXs in the supercritical regime
Ultraluminous X-ray sources (ULXs) with luminosities lying between ∼3 × 10^(39) and 2 × 10^(40) erg s^(−1) represent a contentious sample of objects as their brightness, together with a lack ofExpand
An accreting pulsar with extreme properties drives an ultraluminous x-ray source in NGC 5907
Observations showing that NGC 5907 ULX is instead an x-ray accreting neutron star (NS) with a spin period evolving from 1.43 seconds in 2003 to 1.13 seconds in 2014 suggest that other extreme ULXs (x-ray luminosity ≥ 1041 erg second−1) might harbor NSs. Expand

Resolved atomic lines reveal outflows in two ultraluminous X-ray sources
It is concluded that the compact object in each source is surrounded by powerful winds with an outflow velocity of about 0.2 times that of light, as predicted by models of accreting supermassive black holes and hyper-accreting stellar-mass black holes. Expand
Pulsator-like spectra from Ultraluminous X-ray sources and the search for more ultraluminous pulsars
