EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics

Paolo Soffitta, Sebastien Guillot, Ian Hutchinson +137

The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of…

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…

Time lags as proxy of spectral evolution in gamma-ray bursts

C. Maraventano, F. Daigne, R. Mochkovitch +3

Positive lags in gamma-ray bursts (GRBs), where hard photons anticipate softer ones, provide a unique window into the temporal evolution of their prompt emission. Negative lags, wh…

The first IXPE view of the eclipsing ADC source 4U 1822-37

A. Anitra, A. Gnarini, T. Di Salvo +17

Accretion-disc corona sources are high-inclination low-mass X-ray binaries in which the innermost regions are hidden and the observed X-ray emission is dominated by radiation scatt…

A mysterious feature in the NICER spectrum of 4U 1820-30: A gravitationally redshifted absorption line?

R. Iaria, T. Di Salvo, A. Anitra +6

A mysterious absorption feature at approximately 3.8 keV has been identified in the NICER spectrum of the low-mass X-ray binary system 4U 1820-30. We interpret this feature as a gr…

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…
