Long-Period Transients as a new frontier in time-domain astronomy
Manisha Caleb, Dougal Dobie, Natasha Hurley-Walker +8
Long-period radio transients (LPTs) are relatively new astrophysical objects occupying the observational gap between canonical pulsars and slowly varying radio variables. They emit…
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…
Einstein Probe discovery of EP J171159.4-333253: an eclipsing neutron star low-mass X-ray binary with clocked bursts
Y. L. Wang, F. Coti Zelati, E. Parent +27
EP J171159.4-333253 is a new neutron-star low-mass X-ray binary discovered in outburst by the Einstein Probe (EP) on 2025 June 23, exhibiting clocked type-I X-ray bursts, eclipses…
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…
Einstein Probe Discovery of EP J182730.0-095633: A New Black Hole X-ray Binary Candidate in Faint Outburst?
Huaqing Cheng, Qingchang Zhao, L. Tao +77
Black hole X-ray binaries (candidates) currently identified in our galaxy are mainly transient sources, with the majority discovered through the detection of their X-ray outbursts.…
Einstein Probe discovery of the short period intermediate polar EP J115415.8-501810
Y. Xiao, M. Ge, N. Rea +21
The X-ray transient source EP240309a/EP\,J115415.8501810 was first detected by the Wide-Field X-ray Telescope (WXT) on board Einstein Probe (EP) during the commissioning phase.…
New X-ray Supernova Remnants in NGC 7793
Maria Kopsacheili, Konstantina Anastasopoulou, Nanda Rea +2
This work focuses on the detection of X-ray Supernova Remnants (SNRs) in the galaxy NGC 7793 and the study of their properties. X-ray SNRs in galaxies beyond the Local Group are ra…
On the nature of the X-ray binary transient MAXI J1834-021: clues from its first observed outburst
A. Manca, A. Marino, A. Borghese +14
MAXI J1834-021 is a new X-ray transient that was discovered in February 2023. We analysed the spectral and timing properties of MAXI J1834-021 using NICER, NuStar and Swift data co…
Multi-band study of the flaring mode emission in the transitional millisecond pulsar PSR J1023+0038
M. C. Baglio, F. Coti Zelati, A. K. Hughes +17
We present a comprehensive study of the flaring mode of the transitional millisecond pulsar (tMSP) PSR J1023+0038 during its X-ray sub-luminous state, using strictly simultaneous X…
Detection of X-ray Emission from a Bright Long-Period Radio Transient
Ziteng Wang, Nanda Rea, Tong Bao +46
Recently, a class of long-period radio transients (LPTs) has been discovered, exhibiting emission on timescales thousands of times longer than radio pulsars. Several models had bee…
Einstein Probe discovery of EP240408a: a peculiar X-ray transient with an intermediate timescale
Wenda Zhang, Weimin Yuan, Zhixing Ling +136
We report the discovery of a peculiar X-ray transient, EP240408a, by Einstein Probe (EP) and follow-up studies made with EP, Swift, NICER, GROND, ATCA and other ground-based multi-…
Short-term variability of the transitional pulsar candidate CXOU J110926.4-650224 from X-rays to infrared
F. Coti Zelati, D. de Martino, V. S. Dhillon +14
CXOU J110926.4-650224 is a candidate transitional millisecond pulsar (tMSP) with X-ray and radio emission properties reminiscent of those observed in confirmed tMSPs in their X-ray…
X-ray and optical observations of the millisecond pulsar binary PSRJ1431-4715
D. de Martino, A. Phosrisom, V. S. Dhillon +7
We present the first X-ray observation of the energetic millisecond pulsar binary PSR J1431-4715, performed with XMM-Newton and complemented with fast optical multi-band photometry…
A very young radio-loud magnetar
P. Esposito, N. Rea, A. Borghese +20
The magnetar Swift ,J1818.0-1607 was discovered in March 2020 when Swift detected a 9 ms hard X-ray burst and a long-lived outburst. Prompt X-ray observations revealed a spin perio…
Discovery of a new accreting millisecond X-ray pulsar in the globular cluster NGC 2808
A. Sanna, A. Papitto, L. Burderi +6
We report on the discovery of coherent pulsations at a period of 2.9 ms from the X-ray transient MAXI J0911-655 in the globular cluster NGC 2808. We observed X-ray pulsations at a…
Comparing supernova remnants around strongly magnetized and canonical pulsars
J. Martin, N. Rea, D. F. Torres +1
The origin of the strong magnetic fields measured in magnetars is one of the main uncertainties in the neutron star field. On the other hand, the recent discovery of a large number…
