Discovery of EP J175257.3-351923 as a Candidate Black Hole Low-Mass X-ray Binary

G. L. Huang, Q. C. Zhao, L. Tao +30

We report the discovery of a new X-ray transient, EP J175257.3-351923 (EP250916a), by the Einstein Probe (EP) near the Galactic plane. The outburst lasted for at least 250\,days, r…

A FAST search for radio pulsations during the dormant state of the AMSPs IGR J00291+5934 and MAXI J1957+032

A. Marino, E. Parent, F. Coti Zelati +15

Accreting millisecond pulsars (AMSPs) and transitional millisecond pulsars (tMSPs) are neutron star low-mass X-ray binaries which can evolve into "recycled" radio millisecond pulsa…

The X-ray emission of the long-period transient and accreting cataclysmic variable ASKAP J174508.9-505149

M. Imbrogno, M. Veresvarska, Y. L. Wang +8

Long-period transients (LPTs) challenge our knowledge of the mechanism producing radio periodic pulsations in compact objects. Some LPTs have been associated with systems hosting a…

Multiwavelength Analysis of the Einstein Probe X-ray Transient EP240305a

Ruican Ma, Ye Li, Lian Tao +32

We report multiwavelength observations of EP240305a, an uncatalogued X-ray transient detected by the Einstein Probe on March 5, 2024. The source exhibits distinct characteristics a…

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

A deep X-ray and UV look into the reflaring stage of the accreting millisecond pulsar SAX J1808.4-3658

Caterina Ballocco, Alessandro Papitto, Arianna Miraval Zanon +12

We present an X-ray and UV high-time-resolution monitoring of the final flaring phase of the 2022 outburst of the AMSP SAX J1808.4-3658, based on simultaneous XMM-Newton and HST ob…
