Diagnosing the Fe line complex of the intracluster medium by XRISM high-resolution spectroscopy
K. Fukushima, L. Hirata, N. Y. Yamasaki +17
We aim to test the validity of the CIE framework in the ICM by performing line diagnostics based mainly on resolved Fe-K emission lines. Methods. We analyse Resolve full-array spec…
ORIGIN: Metal Creation and Evolution from the Cosmic Dawn
J. W. den Herder, L. Piro, T. Ohashi +156
ORIGIN is a proposal for the M3 mission call of ESA aimed at the study of metal creation from the epoch of cosmic dawn. Using high-spectral resolution in the soft X-ray band, ORIGI…
Precise determination of the 1s Lamb Shift in hydrogen-like lead and gold ions using microcalorimeters
S. Kraft-Bermuth, V. Andrianov, A. Bleile +9
Quantum electrodynamics in very strong Coulomb fields is one scope which has not yet been tested experimentally with suffcient accuracy to really determine whether the perturbative…
The Hot and Energetic Universe: The X-ray Integral Field Unit (X-IFU) for Athena+
D. Barret, J. W. den Herder, L. Piro +55
The Athena+ mission concept is designed to implement the Hot and Energetic Universe science theme submitted to the European Space Agency in response to the call for White Papers fo…
The Structure of the Relativistic Fe Line in GX 340+0 as Viewed with XRISM/Resolve, NICER, and NuSTAR
R. M. Ludlam, R. Ballhausen, P. Chakraborty +13
We present a 152 ks XRISM/Resolve observation of the persistently accreting Z source GX 340+0. Simultaneous observations also occurred with NuSTAR and NICER for 22.47 ks and 2.7 ks…
A XRISM/Resolve view of the dynamics in the hot gaseous atmosphere of M87
XRISM Collaboration, M. Audard, H. Awaki +138
The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of AGN feedback in a cluster. This proximity allows us…
ASTRO-H White Paper - High Resolution Spectroscopy of Interstellar and Circumgalactic Gas in the Milky Way and Other Galaxies
F. Paerels, N. Yamasaki, N. Anabuki +23
We describe the potential of high resolution imaging spectroscopy with the SXS on ASTRO-H to advance our understanding of the interstellar- and circumgalactic media of our own Gala…
Constraints on the Chemical Enrichment History of the Perseus Cluster of Galaxies from High-Resolution X-ray Spectroscopy
A. Simionescu, S. Nakashima, H. Yamaguchi +32
High-resolution spectroscopy of the core of the Perseus Cluster of galaxies, using the satellite above 2 keV and the - Reflection Grating Spectrometer at lowe…
Science Objectives for an X-Ray Microcalorimeter Observing the Sun
J. Martin Laming, J. Adams, D. Alexander +57
We present the science case for a broadband X-ray imager with high-resolution spectroscopy, including simulations of X-ray spectral diagnostics of both active regions and solar fla…
High-resolution X-ray spectroscopy with XRISM/Resolve reveals super-Solar abundance ratios in Virgo/M87
J. Martin, A. Simionescu, F. Mernier +26
The chemical composition of the intracluster medium (ICM) provides key insights into the enrichment history of galaxy clusters. However, high-resolution abundance measurements with…
Dynamics of AGN feedback in the X-ray bright East and Southwest arms of M87, mapped by XRISM
A. Simionescu, C. Kilbourne, H. R. Russell +24
As the central galaxy in the nearest cluster, M87 provides the best spatial resolution for disentangling the complex interactions between AGN jets and the surrounding environment.…
