Characterizing the Broadband Reflection Spectrum of MAXI J1803-298 During its 2021 Outburst with NuSTAR and NICER
Oluwashina Adegoke, Javier Garcia, Riley Connors +12
MAXI J1803-298 is a transient black hole candidate discovered in May of 2021 during an outburst that lasted several months. Multiple X-ray observations reveal recurring "dipping" i…
Self-Consistent Disk-Reflection Analysis of the Black-Hole Candidate X-ray Binary MAXI J1813-095 with NICER, Swift, Chandra, and NuSTAR
Santiago Ubach, James F. Steiner, Jiachen Jiang +5
We present our analysis of MAXI J1813-095 during its hard state ``stalled'' outburst in 2018. This self-consistent analysis has been carried out using \NICER, \Swift, \Chandra, and…
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…
Detection of Reflection Features in the Neutron Star Low-Mass X-ray Binary Serpens X-1 with NICER
R. M. Ludlam, J. M. Miller, Z. Arzoumanian +17
We present Neutron Star Interior Composition Explorer (NICER) observations of the neutron star low-mass X-ray binary Serpens X-1 during the early mission phase in 2017. With the hi…
A Potential Cyclotron Resonant Scattering Feature in the ULX Pulsar NGC 300 ULX1 seen by NuSTAR and XMM-Newton
D. J. Walton, M. Bachetti, F. Fuerst +14
Based on phase-resolved broadband spectroscopy using - and , we report on a potential cyclotron resonant scattering feature at keV in the pulsed sp…
