AstroSat timing and spectral analysis of the accretion-powered millisecond X-ray pulsar IGR J17591--2342
Akshay Singh, Andrea Sanna, Sudip Bhattacharyya +5
IGR J17591--2342, a transient accretion-powered millisecond X-ray pulsar, was discovered during its 2018 outburst. Here, we present a timing and spectral analysis of the source usi…
Tentative Blazar Candidate EP240709A Associated with 4FGL J0031.5-5648: NICER and Archival Multiwavelength Observations
Mason Ng, Jeremy Hare, Gaurava K. Jaisawal +3
We report on follow-up observations of the recently discovered transient by the Einstein Probe, EP240709A, with the Neutron star Interior Composition Explorer (NICER). We also inco…
Connecting the X-ray/UV variability of Fairall 9 with NICER: A Possible Warm Corona
Ethan R. Partington, Edward M. Cackett, Rick Edelson +7
The Seyfert 1 AGN Fairall 9 was targeted by NICER, Swift, and ground-based observatories for a 1000-day long reverberation mapping campaign. The following analysis of NICER s…
X-ray view of emission lines in optical spectra: Spectral analysis of the two low-mass X-ray binary systems Swift J1357.2-0933 and MAXI J1305-704
A. Anitra, C. Miceli, T. Di Salvo +6
We propose a novel approach for determining the orbital inclination of low-mass X-ray binary systems by modelling the H and H line profiles emitted by the accretion disc, wit…
X-ray spectral properties of the accreting millisecond pulsar IGR J17498-2921 during its 2023 outburst
Giulia Illiano, Alessandro Papitto, Alessio Marino +13
We present a comprehensive study of the X-ray spectral properties of the accreting millisecond pulsar IGR J174982921 during its 2023 outburst. Similar to other accreting millise…
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…
Fast X-ray/IR observations of the black hole transient Swift~J1753.5--0127: from an IR lead to a very long jet lag
Alberto Ulgiati, Federico Maria Vincentelli, Piergiorgio Casella +16
We report on two epochs of simultaneous near-infrared (IR) and X-ray observations with a sub-second time resolution of the low mass X-ray binary black hole candidate Swift J1753.5-…
HERMES: Gamma Ray Burst and Gravitational Wave counterpart hunter
G. Ghirlanda, L. Nava, O. Salafia +67
Gamma Ray Bursts (GRBs) bridge relativistic astrophysics and multi-messenger astronomy. Space-based gamma/X-ray wide field detectors have proven essential to detect and localize th…
The puzzling orbital residuals of XTE J1710-281: is a Jovian planet orbiting around the binary system?
R. Iaria, T. Di Salvo, A. Anitra +8
XTE J1710-281 is a transient eclipsing binary system with a period close to 3.28 hours, hosting a neutron star. The average eclipse duration is 420 seconds, and eclipse arrival tim…
Long gamma-ray burst light curves as the result of a common stochastic pulse-avalanche process
Lorenzo Bazzanini, Lisa Ferro, Cristiano Guidorzi +9
Context. The complexity and variety exhibited by the light curves of long gamma-ray bursts (GRBs) enclose a wealth of information that still awaits being fully deciphered. Despite…
Distribution of number of peaks within a long gamma-ray burst
C. Guidorzi, M. Sartori, R. Maccary +10
The variety of long duration gamma-ray burst (LGRB) light curves (LCs) encode a wealth of information on how LGRB engines release energy following the collapse of the progenitor st…
Ordered magnetic fields around the 3C 84 central black hole
G. F. Paraschos, J. -Y. Kim, M. Wielgus +279
3C84 is a nearby radio source with a complex total intensity structure, showing linear polarisation and spectral patterns. A detailed investigation of the central engine region nec…
