Long term optical variations in Swift J1858.6-0814: evidence for ablation and comparisons to radio properties
L. Rhodes, D. M. Russell, P. Saikia +5
We present optical monitoring of the neutron star low-mass X-ray binary Swift J1858.6-0814 during its 2018-2020 outburst and subsequent quiescence. We find that there was strong op…
Evolution of the Accretion Disk and Corona During the Outburst of the Neutron Star Transient MAXI J1807+132
Sandeep K. Rout, Teo Munoz-Darias, Jeroen Homan +4
Low-mass X-ray binaries with a neutron star as the primary object show a complex array of phenomenology during outbursts. The observed variability in X-ray emission primarily arise…
Polarized multiwavelength emission from pulsar wind - accretion disk interaction in a transitional millisecond pulsar
M. C. Baglio, F. Coti Zelati, A. Di Marco +17
Transitional millisecond pulsars (tMSPs) bridge the evolutionary gap between accreting neutron stars in low-mass X-ray binaries and millisecond radio pulsars. These systems exhibit…
Lack of emission lines in the optical spectra of SAX J1808.4-3658 during reflaring of the 2019 outburst
L. Asquini, M. C. Baglio, S. Campana +5
We present spectroscopy of the accreting X-ray binary and millisecond pulsar SAX J1808.4-3658. These observations are the first to be obtained during a reflaring phase. We collecte…
Geometry of the comptonization region of MAXI J1348630 through type-C quasi-periodic oscillations with NICER
Kevin Alabarta, Mariano Méndez, Federico García +5
We use the rms and lag spectra of the type-C quasi-periodic oscillation (QPO) to study the properties of the Comptonisation region (aka corona) during the low/hard and hard-interme…
X-ray and optical polarization aligned with the radio jet ejecta in GX 339-4
G. Mastroserio, B. De Marco, M. C. Baglio +27
We present the first X-ray polarization measurements of GX 339-4. IXPE observed this source twice during its 2023-2024 outburst, once in the soft-intermediate state and again durin…
An IXPE-Led X-ray Spectro-Polarimetric Campaign on the Soft State of Cygnus X-1: X-ray Polarimetric Evidence for Strong Gravitational Lensing
James F. Steiner, Edward Nathan, Kun Hu +134
We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May-June. Companion multiwav…
