New Constraints on Axion-Like Particles from IXPE Polarization Data for Magnetars
Ephraim Gau, Fazlollah Hajkarim, Steven P. Harris +4
We derive new constraints on axion-like particles (ALPs) using precision -ray polarization studies of magnetars. Specifically, we use the first detection of polarized -rays f…
IXPE and XMM-Newton observations of the Soft Gamma Repeater SGR 1806-20
Roberto Turolla, Roberto Taverna, Gian Luca Israel +96
Recent observations with the Imaging X-ray Polarimetry Explorer (IXPE) of two anomalous X-ray pulsars provided evidence that X-ray emission from magnetar sources is strongly polari…
Evaluation of several explanations of the strong X-ray polarization of the black hole X-ray binary 4U 1630-47
Henric Krawczynski, Yajie Yuan, Alexander Y. Chen +6
The Imaging X-ray Polarimetry Explorer (IXPE) observations of the X-ray binary 4U 1630-47 in the high soft state revealed high linear polarization degrees (PDs) rising from 6% at 2…
The First X-ray Polarization Observation of the Black Hole X-ray Binary 4U 1630-47 in the Steep Power Law State
Nicole Rodriguez Cavero, Lorenzo Marra, Henric Krawczynski +107
The Imaging X-ray Polarimetry Explorer (IXPE) observed the black hole X-ray binary 4U 1630-47 in the steep power law (or very high) state. The observations reveal a linear polariza…
A strong X-ray polarization signal from the magnetar 1RXS J170849.0-400910
Silvia Zane, Roberto Taverna, Denis Gonzalez Caniulef +99
Magnetars are the most strongly magnetized neutron stars, and one of the most promising targets for X-ray polarimetric measurements. We present here the first Imaging X-ray Polarim…
ASCENT - A balloon-borne hard X-ray imaging spectroscopy telescope using transition edge sensor microcalorimeter detectors
Fabian Kislat, Daniel Becker, Douglas Bennett +26
Core collapse supernovae are thought to be one of the main sources in the galaxy of elements heavier than iron. Understanding the origin of the elements is thus tightly linked to o…
