A0538-66: A transient ultraluminous X-ray source with a relativistic outflow, 69ms pulsations, and anomalous optical activity
Lorenzo Ducci, Sandro Mereghetti, Ciro Pinto +8
A0538-66 is a peculiar Be/X-ray binary in the Large Magellanic Cloud, hosting the fastest spinning neutron star of its class (~69ms) and showing the brightest optical bursts of any…
A relativistic inflow candidate in a quasar at cosmic noon
Yerong Xu, Xiurui Zhao, Elena Bertola +14
Cosmic noon () marks the peak epoch of cosmic star formation and black hole accretion activity, where strong accretion and outflows are expected. We report two candidate ab…
XRISM/Resolve observations of Hercules X-1: a pulsating, highly broadened Fe K emission line from the neutron star accretion column
Peter Kosec, Laura Brenneman, Erin Kara +11
The study of X-ray pulsar accretion columns helps us characterize accretion physics in this extreme regime of strong gravity and strong magnetic fields. Previous observations of th…
XRISM/Resolve observations of Hercules X-1: vertical structure and kinematics of the disk wind
Peter Kosec, Laura Brenneman, Erin Kara +11
X-ray binary accretion disk winds can carry away a significant fraction of the matter transferred from the companion and hence strongly affect the accretion flow and the long-term…
Millihertz Oscillations Near the Innermost Orbit of a Supermassive Black Hole
Megan Masterson, Erin Kara, Christos Panagiotou +22
Recent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repet…
Line detections in photospheric radius expansion bursts from 4U 1820-303
F. Barra, D. Barret, C. Pinto +3
Context: NICER (Neutron star Interior Composition ExploreR) is the instrument of choice for the spectral analysis of type I X-ray bursts, as it provides high throughput at X-ray CC…
