NuSTAR's Intentional Stray Light Observation of Scorpious X-1
S. Li, R. M. Ludlam, M. Sudha +8
We present the first spectral analysis of Scorpius X-1 (Sco X-1) using intentional stray light (SL) observations taken by NuSTAR. Unlike focused observations that have high telemet…
Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry
Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97
RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…
Spatially resolved polarization variation of the Crab Nebula
Chao Zuo, Fei Xie, Mingyu Ge +6
We examined the spatially resolved polarization variations in the Crab Nebula over 2 yr, using observational data from the Imaging X-ray Polarimetry Explorer, and offer key insight…
First X-ray polarimetric view of a Low-Luminosity Active Galactic Nucleus: the case of NGC 2110
Sudip Chakraborty, Ajay Ratheesh, Daniele Tagliacozzo +20
Low-Luminosity Active Galactic Nuclei (LLAGN) provides a unique view of Comptonization and non-thermal emission from accreting black holes in the low-accretion rate regime. However…
The IXPE View of Neutron Star Low-Mass X-ray Binaries
Francesco Ursini, Andrea Gnarini, Fiamma Capitanio +9
Low-mass X-ray binaries hosting weakly magnetized neutron stars (NS-LMXBs) are among the brightest sources in the X-ray sky. Since 2021, the Imaging X-ray Polarimetry Explorer (IXP…
X-ray Polarization of the Eastern Lobe of SS 433
Philip Kaaret, Riccardo Ferrazzoli, Stefano Silvestri +103
How astrophysical systems translate the kinetic energy of bulk motion into the acceleration of particles to very high energies is a pressing question. SS 433 is a microquasar that…
A Spatially resolved X-ray Polarization map of the Vela Pulsar Wind Nebula
Kuan Liu, Fei Xie, Yi-Han Liu +12
In this paper, we present a full spatially resolved polarization map for the Vela Pulsar Wind Nebula (PWN) observed by IXPE. By employing effective background discrimination techni…
The X-ray Polarization View of Mrk~421 in an Average Flux State as Observed by the Imaging X-ray Polarimetry Explorer
Laura Di Gesu, Immacolata Donnarumma, Fabrizio Tavecchio +100
Particle acceleration mechanisms in supermassive black hole jets, such as shock acceleration, magnetic reconnection, and turbulence, are expected to have observable signatures in t…
