Ultra-long period compact sources: a glimpse into observational breakthroughs and theoretical challenges
Francesco Coti Zelati, Alice Borghese
At the Seventeenth Marcel Grossman meeting, researchers gathered to discuss significant advances in the study of ultra-long period sources. Presentations covered key aspects, inclu…
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-…
Millisecond pulsars phenomenology under the light of graph theory
C. R. García, G. Illiano, D. F. Torres +4
We compute and apply the minimum spanning tree (MST) of the binary millisecond pulsar population, and discuss aspects of the known phenomenology of these systems in this context. W…
High-temporal-resolution optical spectroscopic observations of the transitional millisecond pulsar PSR J1023+0038
M. M. Messa, P. D'Avanzo, F. Coti Zelati +2
Transitional millisecond pulsars (tMSPs) represent a dynamic category of celestial sources that establish a crucial connection between low-mass X-ray binaries and millisecond radio…
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 2.9-hour periodic radio transient with an optical counterpart
N. Hurley-Walker, S. J. McSweeney, A. Bahramian +12
We present a long-period radio transient (GLEAM-X J0704-37) discovered to have an optical counterpart, consistent with a cool main sequence star of spectral type M3. The radio puls…
Discovery of Polarized X-Ray Emission from the Accreting Millisecond Pulsar SRGA J144459.2-604207
Alessandro Papitto, Alessandro Di Marco, Juri Poutanen +22
We report on the discovery of polarized X-ray emission from an accreting millisecond pulsar. During a 10-day-long coverage of the February 2024 outburst of SRGA J144459.2-604207, t…
Einstein Probe discovery of EP J005245.1-722843: a rare BeWD binary in the Small Magellanic Cloud?
A. Marino, H. Yang, F. Coti Zelati +32
On May 27 2024, the Wide-field X-ray Telescope onboard the Einstein Probe (EP) mission detected enhanced X-ray emission from a new transient source in the Small Magellanic Cloud (S…
Swift X-Ray and UV Observations of six Gaia Binaries supposedly containing a Neutron Star
B. Sbarufatti, F. Coti Zelati, A. Marino +3
Recent observations have led to the discovery of numerous optically selected binaries containing an undetected component with mass consistent with a compact object (neutron star or…
An X-ray and radio view of the 2022 reactivation of the magnetar SGRJ1935+2154
A. Y. Ibrahim, A. Borghese, F. Coti Zelati +19
Recently, the Galactic magnetar SGR J1935+2154 has garnered attention due to its emission of an extremely luminous radio burst, reminiscent of Fast Radio Bursts (FRBs). SGR J1935+2…
Long-term study of the 2020 magnetar-like outburst of the young pulsar PSRJ1846-0258 in Kes 75
Rajath Sathyaprakash, Nanda Rea, Francesco Coti Zelati +14
Magnetar-like activity has been observed in a large variety of neutron stars. PSR J1846-0258 is a young 327 ms radio-quiet pulsar with a large rotational power ($\sim 8 \times 10^{…
